What is Cat8 Cable? For the past two decades, people have challenged the use of Ethernet and Network Cabling. It was believed by some that Ethernet would soon be a thing of the past. Yet, even after Google’s attempts with fiber optics, Ethernet remained the standard for home and commercial networks.
Throughout the years, Ethernet has developed and changed. Every so often new iterations would arise. The various “Cat” designations have gone from Cat5e to Cat6 and Cat6a, and then Cat7 in previous years. But now, we have Cat8 Cables. Cat8 has caused a lot of excitement with IT Network Technicians, Data Centers and now even installers who work in the field of Video/Audio Surveillance. With Cat8, many iterations were surpassed making Cat8 the Ethernet cable one would select to go further into the future. Although this is particularly beneficial in larger applications such as Data Centers, many enthusiastic tech savvy business owners and even gamers have already looked at Cat8 for their networks.
Just to review the differences between all “the Cats” we can see why Cat8 is taking us on a forward path to faster and more efficient data transfer and recovery. Cat5 operates at 100 MHz and transfers data at speeds up to 1000 Mbps. Cat6 works at 250 MHz and can get up to 1 Gbps. Cat7 is impressive with 600 MHz and 10 Gbps rates. These are the numbers on each Category Cable that have been tested and vetted.* Yet Cat8 uses 2000 Mhz signals to move data from 25 Gbps (Cat8.1) to 40 Gbps (Cat8.2). This is exponentially higher than each iteration of Ethernet cable previously.
So, why is Cat5 slower? First of all, it’s cheaper. The production of Cat5 requires less twists and shielding. Cat5 is therefore less expensive to produce. With fewer twists in the cable pairs it becomes increasingly difficult to shield higher frequencies, interference and crosstalk.
So, if it’s the twists and shielding we need to get higher frequencies, the production costs makes Cat7 and Cat8 more expensive. But the raw materials made Cat7 much more expensive. Cat7 often uses gold plates for shielding. Cat8 is less expensive than Cat7. One of the most popular and trusted types of shielding for Cat8 is S/FTP. This is a process that insures each pair shielded is foil wrapped and then a 4-pare shield is around the group of wires. The raw material is copper, much less expensive than gold.
With the exponentially higher Mhz signals Cat8 will “Future Proof” your home or business. And with all the wrapping and shielding Cat8 still has the physical appearance of the lower category cables, but is significantly thicker. Cat8 uses the 8-pin modular (RJ45) connector, the same used in previous versions. This means that Cat8 (Cat-8, Category 8) Cables are backwards compatible with Cat5e, Cat6, Cat6a and Cat7 cabling.
What particularly attractive about Cat8 is it does not require more power. The 25GBASE-T/40GBASE-T equiptment is designed to operate over shorter distances up to a maximum of 30 meters. The power needed to transmit a signal 30 meters at 40 Gb/s is approximately the same as the power needed for 10GBASE-Tn transmission for distances up to 100 meters. There are always contributing factors to deciding which Network Cabling will work best for your application. However, if you are looking for Category Cables that will stand up to the requirements of the future, CAT8 is a perfect option!

1080p (1920×1080 px: also known as Full HD, is a set of HD High Resolution Video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as full HD, to contrast 1080p with 720p resolution.
4 Megapixel Cameras security cameras that are capable of providing video resolutions up to 2560 x 1440 pixels which is 30% greater than HD1080p.
This refers to one of two resolutions. 3840 x 2160, or 4096 x 2160. It is 4 times the resolution of 1080p. This will also allow much higher zoom rates on stills taken from any video clips.
5 Megapixel CCTV cameras are capable of resolutions up to 2560 x 1920. These cameras do have a different aspect ratio than 4MP, however. So there is a slight trade off.
720p refers to an image resolution of 1280 pixels wide by 720 pixels tall. Originally a standard for HD (high-definition) television, it can refer to the resolution of video content, the recording capability of a video camera.

This can be a physical wired device like PIR Sensor, Door sensor, Glass break sensor, Smoke sensor etc., that recognize any suspicious activity that triggers alarm output such as sending e-Mails and uploading video on FTP server. Alarm inputs on a DVR, XVR or NVR can be used for connecting additional devices.
In CCTV, analog refers to a Camera Video Format. This refers to systems and components that use the Video standard NTSC/PAL composite video formats. New technology has allowed Analog to attain high resolutions which are reffered to as HD Analog or HDCCTV. Current HD Resolutions are up to 8MP as of 2019.
Angle of View

In CCTV DVR context backup refers to saving a selected clip of video to an external device for the purpose of reviewing the clip in a standard PC. This is also called as Export
Balun (Active / Passive)
This is a device that allows video to travel over a twisted pair (Cat 5) wire rather than coax (RG 59) cable. This device matches the impedances of the different signals. Balun stands for balanced-unbalanced. A balun is required at the transmitting device (camera) and receiving device (DVR, monitor, etc.). Passive distance can be up to 990’ (300Mtrs) and active can be up to 9900’ (3 Km). Also referred to as a Video Balun.
Device bandwidth is the range of signal frequencies that a piece of audio or video equipment can encode or decode (the operating frequency). Video uses a wider/higher frequency range than audio, thus requires a wider bandwidth.
This refers to a feature in some DVRs and Remote Software that limits the size of the network traffic provided. This feature restricts DVR/Remote software communication so more bandwidth remains available for other network traffic.
Base Band Video
This is the video signal used in CCTV. It is the NTSC or PAL format minus the broadcast frequency modulation and many other embedded signals used in Broadcast TV. It consists of video, horizontal sync and vertical sync. This is all that is required to view a video signal on a monitor
Bit rate is measured in bits per second. In IP video it usually refers to the bit rate from an IP camera. Controlling the bit rate controls the bandwidth needed to transfer data from the camera. The camera processor will automatically limit the maximum bit rate sent from the camera to the bit rate setting selected.
Individual parts of data communication. A bit is the smallest part of the overall data stream. Serial communication is measured in bits per second (RS-232, RS-485, etc.).

This is the standard connector type used in CCTV. It provides an easy snap-on connection for a coax cable. What BNC stands for is less clear. Some say it means British Naval Connector. Others attribute it to the type and the inventor; Bayonet Neil Councilman.
This is the basic video collection device that has many forms and configurations. Some are: box cameras (require a separate lens), bullet cameras (slim line all in one construction), dome camera (all in one in a dome design), PTZ camera (mounted on a PTZ platform device), PTZ dome (all in one package). An IP or HD camera can be any of these and connect directly to a network.
CAT5 is a network cable that supports Ethernet speeds (up to 100 Mbps). As with all other types of twisted pair EIA/TIA cabling, CAT5 cable runs are limited to a maximum recommended run length of 95mtrs (313 feet) & it can be available in 2. Market contains four pairs of copper wire.
Is similar to CAT-5, the ‘e’ standing for enhanced. This cable has more ability for data transmission. Cat-5e also can be used for Gigabit Ethernet and generally has less near-end crosstalk. In new cabling system CAT5e cables are almost always used over CAT5.
Is a most sophisticated cables, it is also comprised of four pieces of twisted pair copper wire, it has a longitudinal separator. This allows the cables to be separated from each other and, in turn, allows not only for an increased data transfer speed, but less crosstalk and double the bandwidth. CAT6 cabling is a good choice for IP Camera & NVR, especially those that are evolving and might need more options in the future. CAT-6 is perfect for 10 Gigabit Ethernet and can work at up to 250 MHz.
Charged Coupled Device is a type of image sensor used in CCTV cameras. The sensor converts optical images in to electrical signals. These are also known in the market as HAD CCD, IT CCD, Super HAD CCD.

The Internet has changed all that. Now you can access any DVR with browser software through the Internet. CCTV has continued to be used to refer to surveillance Cameras and systems of all types.
An acronym for Common Intermediate Format, a set of standard video formats, defined by their resolution. CIF resolution is 352 x 288 pixels and is also known as D1 720 x 576, 2CIF, 4CIF, 960H.
Complementary Metal Oxide Semiconductor imaging chip is a type of Active Pixel Sensor made using the CMOS semiconductor process. Extra circuitry next to each photo sensor converts the light energy to a voltage. Additional circuitry on the chip may be included to convert the voltage to digital data. CMOS cameras were originally low in quality but typically less expensive than a CCD sensor. This has been known in the market as HDIS/ HQIS/ DIS/ QIS Sensors, or flicker less camera etc.

This is an acronym for Central Management Software. This is a generic term used to indicate the installable remote software packages provided by any DVR manufacturer. Each manufacturer has a specific name for their CMS product.
Coaxial Cable (COAX)
A type of shielded cable capable of carrying a wide range of frequencies (video or radio) with very low signal loss. Used in CCTV and HD CCTV applications with BNC Connectors
This stands for Compressor/De-compressor. Some people call it encoder/decoder. This refers to the software that compresses or decompresses the video.
Video must be compressed in size in order to make it manageable in the record and remote transmit functions. Typical compression standards include H.264 / M-JPEG & MPEG-4. Some DVR manufacturers use proprietary compression methods that are usually modified versions of the standards.
Contrast is the difference in the color and brightness of the object and other objects within the same field of view.
The ratio between white and black. The larger the contrast ratio the greater the ability of a projector to show subtle color details and tolerate extraneous room light. There are two methods used by the projection industry: 1) Full On/Off contrast measures the ratio of the light output of an all white image (full on) and the light output of an all-black (full off) image. 2) ANSI contrast is measured with a pattern of 16 alternating black and white rectangles. The average light output from the white rectangles is divided by the average light output of the black rectangles to determine the ANSI contrast ratio. When comparing the contrast ratio of projectors make sure you are comparing the same type of contrast. Full On/Off contrast will always be a larger number than ANSI contrast for the same projector.
A covert camera is a camera that is not visible or noticeable. It is intentionally obscured from view and often used for surveillance of employees. Covert Cameras can be hidden in a variety of devices, including PIR Sensors, Smoke Detectors etc. These Cameras are also referred to as Hidden Cameras, Nanny Cameras and Concealed Cameras.

HD-CVI (High Definition Composite Video Interface). This video format enabled analog CCTV signals to move into the high-definition range. Prior to this, it was limited to 960h.
DDNS stands for dynamic DNS, or more specifically dynamic Domain Name System. It’s a service that maps internet domain names to IP addresses. DDNS is commonly used for NVR’s, DVR’s and IP Cameras when attempting to remotely connect to your system.
Depth of Field
This is the in-focus range of the image produced by the lens. Objects in the focus area are clear. They will become less clear as they get closer to, or further away from the camera. The distance of the area of clear focus is the depth of field.
This is an acronym for Dynamic Host Configuration Protocol. This is a function that allows a network to automatically assign an IP address to a PC when the user logs on to the system. All devices on a network require an IP address. DHCP does this automatically. The alternative is to manually enter a static IP address in each device.
This refers to enlarging a portion of an image by adding additional pixels within the image to fill the larger area. It makes the picture area larger at the expense of video quality. The intelligence for this feature can be in a camera or a DVR. The opposite would be Optical Zoom in which a camera physically zooms into an image using all available pixels.
Domain Name System matches internet computer names to IP numbers.
A number of computer devices administered as a group. A Domain server is set up and maintained by the network administrator (the person in charge of the network).
Device Driver is a software program that allows a computer to communicate with a peripheral. You need the appropriate driver to allow your printer to work with your system. Many drivers are available on a PC as part of the operating system. However, don’t depend on this as drivers for devices newer than the operating system will not be installed. You typically get a copy of the driver with the purchased device. The manufacturer’s web site is a common place to get the latest available drivers for a device. Drivers are often referred to as DLLs (dynamic link library). Virtually all drivers used in CCTV devices are proprietary. So once you get away from the standard stuff you have to rely upon the manufacturer’s good will for interface help.
An acronym for Digital Video Recorder, this is a manufacturer designed hardware platform for recording. It may have many functions like Recorder/ Multiplexer/ Remote surveillance/ Alert notification. It is a proprietary design that is unique to an individual manufacturer. DVR’s are commonly used in HD CCTV and generally will have BNC Inputs. DVR’s range from 4 Channel to 32 Channel. New versions of HD DVR’s which support multiple HD Formats are called XVR’s.
This refers to IP addresses that are automatically assigned to a network device when the user logs on to the system. See DHCP.
Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether.

Each complete video image in NTSC/PAL (frame) is composed of two fields. One field consists of the odd numbered lines in the frame and the other field consists of the even numbered lines. When viewed together in rapid succession, these lines form the complete frame image. The NTSC and PAL formats called for double scanning fields to reduce the visual flicker that was common on early TV monitors. Monitors got better over time but the “standard” did not change. Each individual field independently forms a picture.
The distance between the secondary principal point in the lens and the plane of the imaging device. The longer the focal length, the narrower is the angle of view.

These are IP based video cameras using IP networking as their basis rather than the traditional video signal used in broadcast and closed circuit systems. Migration to IP Cameras increased due to higher resolution capabilities as well as capabilities. However, HD Analog Cameras have bridged the gap on resolution dramatically (Currently up to 8MP).
This stands for Ingress Protection. It is a measure of the ability of an enclosure to resist dust and water. It is expressed (usually) as two numbers as in IP66. This rating would mean your outdoor dome enclosure is totally resistant to dust and water entry.
IPv4 Internet Protocol Address form of IP address is a number address of 32 bits appearing by 4 numbers that is parted by period. Each number can be from to 255 from 0.
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.
Infra-Red light is the wavelength of light produced below the visible part of the spectrum. Humans can’t see this light but cameras can. IR cameras use Infra-Red LEDs to light an area and provide usable (black and white) images in total darkness.
IR Cut Filter
IR light can distort colors in CCD and CMOS cameras. An IR filter is often used in cameras to filter out IR light during bright daylight conditions. An IR cut filter is automatically removed at low light to allow the camera to take advantage of IR light in lower light conditions. The camera usually switches to black and white operation at this time since B/W works better than color in low light. However, new Starlight Cameras have emerged as a way for Cameras to stay in color in extremely low light levels.

The term private network is pretty generic. Generally it means that the network is restricted to specific users. This could range from a separate grouping of computers connected locally, two LANs connected together through a phone connection, to a complex “Intranet” that is accessed through the Internet, yet only available to authorized users. The Intranet version is often referred to as a “Virtual Private Network.” In the case of Digital Video Recorders and their remote software connections, we refer to a private network as a separate grouping of security devices that are not connected directly to the normal company business network. The advantage of this private network is that you have all the bandwidth available for a specific purpose and you will not affect other company business in the case of a failure.
In CCTV context proprietary indicates a non-standard method of accomplishing something. This may be good or bad depending on the results. (usually bad). Some proprietary software solutions were developed by manufacturers before the current standards were implemented. Some are attempts to intentionally circumvent the ability to work with other manufacturer’s equipment. Most were just developed separately with no thought of how anyone else approached the same issue. A downfall of Proprietary equipment is that once the manufacturer stops supporting it, your system is effectively defunct.
In CCTV context a protocol is the command set used to control one device from another. An example is that each manufacture develops their own code to send commands to PTZ domes. This is why you see so many options for camera control in DVRs. The protocol is the software element. The hardware element is RS-422, RS-485, etc.

The data is transferred during the Vertical Blanking Interval (that wide black line you might see on a rolling image) and does not interfere with the video display. This is especially helpful in installation and allows UTC compatible cameras and DVR’s to communicate with each other without having to run an additional cable. Our STOiC XVR’sare all UTC Supported.
An acronym for Unshielded Twisted Pair, known as network cable CAT 5 UTP or CAT 6 UTP Cable
Vari-Focal Lens (Variable Focus)

A camera viewing an image with very bright and very dark sections will probably not show any detail in the dark areas as the camera is adjusted to tone down the bright areas. With WDR the camera view will be much improved showing detail in both light and dark areas. This feature also provides better image detail in low light conditions.
Is a WLAN (Wireless Local Area Network) technology. It provides short-range wireless high-speed data connections between IP cameras to nearby Wi-Fi access points. Wi-Fi has different types of encryptions standard WPA / WPA2 / WEP for secured access. There are variants of Wi-Fi, 802.11g, is capable of providing speeds of up to 54Mbps and is backwards compatible with 802.11b.
An XVR is a DVR that can support multiple formats. HD XVR’s can support AHD, TVI, CVI, CVBS and IP simultaneously. They also have an auto detect feature so cameras from multiple formats can be recognized instantly without having to switch any settings.

UL and C-UL Classifications for Hazardous Locations
Gain a better understanding of the definition of a Hazardous Location and area classification as well as the UL and C-UL Certification for North America.
What is a Hazardous Location?
Location where explosion or fire hazards exist due to the presence of flammable gases, flammable or combustible liquid-produced vapors, combustible dusts, or ignitable fibers or flyings.
How are Hazardous Areas Classified?
Area Classification – Hazardous Locations are classified by the likelihood of an ignitable concentration of combustible material being present. There are two systems in place, including the traditional North American Division system as well as the alternative Zone system. See below for further details:
DIVISION SYSTEM (NEC ARTICLE 500 THROUGH 503/CEC SECTION 18)
Division 1 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produces vapors can exist under normal operating conditions.
Division 2 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produces vapors are not likely to exist under normal operating conditions.
Class – Materials are divided by type:
Class I – Flammable gases, flammable liquid produced vapors, and combustible liquid produced vapors
Class II – Combustible dusts
Class III – Ignitable fibers / flyings
Groups – Materials are further divided into Groups for Class I, Divisions 1 and 2:
A – Acetylene
B – Hydrogen
C – Ethylene
D – Propane
Groups – Materials are further divided into Groups for Class II, Division 1 and 2:
E – Metal Dusts (Div. 1 only)
F – Carbonaceous Dusts
G – Non-Conductive Dusts (flour, grain, wood, plastic, etc.)
What is the difference between a Class I, Division 1 Location and Class I, Division 2 Location? What about the differences between the other locations?
Class I, Division 1 Location
Ignitable concentrations of flammable gases, vapors or liquids:
can exist under normal operating conditions;
may exist frequently because of repair or maintenance operations or leakage; or
may exist because of equipment breakdown that simultaneously causes the equipment to become a source of release.
Class I, Division 2 Location
Volatile flammable liquids or flammable gases or vapors exist, but are normally confined within closed containers;
Ignitable concentrations of gases, vapors or liquids are normally prevented by positive mechanical ventilation; or
Adjacent to a Class I, Division 1 location where ignitable concentrations might be occasionally communicated.
Class II, Division 1 Location
Ignitable concentrations of combustible dust can exist in the air under normal operating conditions;
Ignitable concentrations of combustible dust may exist because of equipment breakdown that simultaneously causes the equipment to become a source of ignition; or
Electrically conductive combustible dusts may be present in hazardous quantities.
Class II, Division 2 Location
Combustible dust is not normally in the air in ignitable concentrations;
Dust accumulations are normally insufficient to interfere with normal operation of electrical equipment;
Dust may be in suspension in the air as the result of infrequent malfunction of equipment; or
Dust accumulation may be sufficient to interfere with safe dissipation of heat or may be ignitable by abnormal operation.
Class III, Division 1 Location
A location in which easily ignitable fibers or materials producing combustible flyings are handled, manufactured or used.
Class III, Division 2 Location
A location in which easily ignitable fibers are stored, or handled other than in the process of manufacture.
ZONE SYSTEM (NEC ARTICLE 505-506 / CEC SECTION 18)
Zone 0 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produces vapors are present continuously or for long periods of time under normal operating conditions.
Zone 1 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produces vapors are likely to exist under normal operating conditions.
Zone 2 – Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produces vapors are not likely to exist under normal operating conditions.
Zone 20 – Ignitable concentrations of combustible dust or ignitable fibers/flyings are present continuously or for long periods of time under normal operating conditions.
Zone 21 – Ignitable concentrations of combustible dust or ignitable fibers/flyings are likely to exist occasionally under normal operating conditions.
Zone 22 – Ignitable concentrations of combustible dust or ignitable fibers/flyings are not likely to occur under normal operating conditions.

Equipment Protection Level (EPL) –Level of protection assigned to equipment based on its likelihood of becoming a source of ignition and distinguishing the differences between explosive gas atmospheres, explosive dust atmospheres, and the explosive atmospheres in mines susceptible to fire damp.
EPL Ma – Equipment for installation in a mine susceptible to firedamp, having a very high level of protection, which has sufficient security that it is unlikely to become an ignition source in normal operation, during expected malfunctions or during rare malfunctions, even when left energized in the presence of an outbreak of gas.
EPL Mb – Equipment for installation in a mine susceptible to firedamp, having a high level of protection, which has sufficient security that it is unlikely to become a source of ignition in normal operation or during expected malfunctions in the time span between there being an outbreak of gas and the equipment being de-energized.
EPL Ga – Equipment for explosive gas atmospheres, having a very high level of protection, which is not a source of ignition in normal operation, during expected malfunctions or during rare malfunctions.
EPL Gb – Equipment for explosive gas atmospheres, having a high level of protection, which is not a source of ignition in normal operation or during expected malfunctions.
EPL Gc – Equipment for explosive gas atmospheres, having an enhanced level of protection, which is not a source of ignition in normal operation and which may have some additional protection to ensure that it remains inactive as an ignition source in the case of regular expected occurrences (for example failure of a lamp).
EPL Da – Equipment for explosive dust atmospheres, having a very high level of protection, which is not a source of ignition in normal operation, during expected malfunctions, or during rare malfunctions.
EPL Db – Equipment for explosive dust atmospheres, having a high level of protection, which is not a source of ignition in normal operation or during expected malfunctions.
EPL Dc – Equipment for explosive dust atmospheres, having an enhanced level of protection, which is not a source of ignition in normal operation and which may have some additional protection to ensure that it remains inactive as an ignition source in the case of regular expected occurrences (for example failure of a lamp).

So H.264 vs H.265. We’ve been hearing a lot about H.265 compression and how it’s better than H.264. Well… how do you quantify ‘better’? Seeing hypothetical numbers on paper is one thing but seeing it in a real-world application is quite another. We decided to see exactly what kind of gain we would get in compression on a 4K system.
Our test system is a TruView 4K 4ch NVR (THK-NR32P4-4) with a 1TB Western Digital WD10PURX (Purple). Our camera is the TruView 4K NC-328-XB.
We’re keeping everything fairly stock, but we’re bumping up the recording quality to ‘Highest’ and maxing out the frame rate. Essentially, we want to make sure that there’s a good amount of drive space being taken up. The picture above is for the first 24 hours on H.264.
We formatted the hard drive and began the test at 4:15PM. Again, this will run for a full 24-hour period, and we’ll record how much drive space was taken up. Then we’ll run the same test with H.265 compression and see how it differs.
You may be wondering what exactly H.264 and H.265 are.
“H.264 or MPEG-4 Part 10, Advanced Video Coding is a block-oriented motion-compensation-based video compression standard. As of 2014 it is one of the most commonly used formats for the recording, compression, and distribution of video content. It supports resolutions up to 8192×4320, including 8K UHD. (H.264/MPEG-4 AVC, n.d.)”
H.265 takes this a step further.
So, what does that mean exactly? In the most oversimplified way that I can think to put it, it’s an encoding method that allows video to look great while not taking up as much storage space. Older encoding methods, for example MPEG-2, take up quite a bit more storage space than MPEG-4. With the introduction of H.265 to the CCTV world, it could mean much more efficient hard drive use. Especially for those who need a couple of weeks of video on hand. Or for those who need to store video for even longer periods of time. Some industries require a month or more for storage. This becomes even more significant in larger installs with 30 or more cameras.
We completed our first 24 hours and here are the results:
Start Time: 4:15PM 6/4/18
Camera: NC328-XB @8MP 4K 3840×2160
Duration: 24 Hours Continuous Recording
Starting Drive Space: 931GB
Ending Drive Space: 827GB
Space Used: 104GB
Exported Video Size: 1GB (14min 11sec)
Now that we have our first day finished, let’s switch over to H.265, format the HDD, and begin the wait. The only thing we’re changing here is H.264 to H.265.
While we’re waiting on the H.265 video to finish up, let’s check the video quality of the previous recording.
In my opinion, the video looks good. Pretty much as expected for this camera and this compression.
You can even make out the small lettering in my tattoo.
Let’s see how the H.265 turns out.
Start Time: 4:27PM 6/5/18
Camera: NC328-XB @8MP 4K 3840×2160
Duration: 24 Hours Continuous Recording
Starting Drive Space: 929GB
Ending Drive Space: 904GB
Space Used: 25GB
We wanted to see what kind of HDD use we would get over the weekend, so we left the camera running. From 6/7/18 @ 3:10PM to 6/11/18 @ 9:30AM, the drive only used a further 44GBs of storage space. So in total, less than 70GB of storage for about three and a half days. 34GBs less than H.264 took up within 24 hours. It should be mentioned at this point that both sets of data were gathered in a room with very little motion.
This space savings does come at a bit of a cost, though.
The processing power needed to achieve this level of compression is fairly high. Quality doesn’t suffer as much as you may think, but there is a difference. Here’s how I’d personally break this down, at least until the processing concerns are settled.
3x 8TB HDDs (24TB Total)
32 8MP IP Cams
5 of those cameras are in important areas that need to be recording 24hrs a day. We’ll call this Group A.
27 are for overview or in areas that aren’t going to be occupied at night or on weekends. This will be Group B.
My recommended set up would be to keep Group A on 24 hour recording on H.265, and keep Group B on motion recording with H.264. This would allow coverage where it’s needed and conserve HDD space. It would also conserve CPU usage. Like I said earlier, some people may not be as concerned with disk space, but there are situations where it’s a necessity.
In the end, we recommend it if you need the storage space and if you have the resources to utilize H.265.
If you are searching for a better camera for your HD Security Camera System we have some great options for you. The new 5MP Starlight Bullet Cameras from Stoic Technologies, are a welcome addition to our 5MP HD over Coax Line Up. These new starlight cameras have been extremely well received by our Dealers and End Users alike. While many manufacturers have been focusing their efforts on current IP trends, Stoic has been concentrating on image quality, and it shows.
We have tested the Stoic Technologies 5MP Cameras against several leading security camera manufacturers and one common theme seems to be evident. Image quality (based on several aspects) is consistently highest in the Stoic Cameras. Especially significant is that the Stoic Starlight Cameras visibly outperform in the dark, including a one to one test with popular EXIR style cameras. We tested this without activating the Starlight Capabilities, and just going IR mode to IR mode.
New 5MP Zoom Models:
The newest 5MP Vari-Focal Starlight Bullet Cameras from Stoic, are available in two models. The STH-B5580W has Manual Zoom and Focus, and the STH-B5571AFW features Motorized Zoom and Auto Focus. Both models deliver images up to 200 Feet in complete darkness and employ a Sony Starlight Back-Lit Image Sensor for acquiring Color Images in extremely Low Light situations.
Manual Zoom means that you can manually (or physically) adjust the angle of view, or zoom the camera in and out in order to get the perfect picture for your application. Most cameras sold today are ‘Fixed’ lens cameras which cannot be adjusted to compensate for different applications. The benefit of a Vari-Focal, or Zoom Camera is its flexibility. For example, let’s say you need one of your Security Cameras to Zoom out to the end of your driveway, but another needs to cover a wider area. A vari-focal or zoom camera can handle either application. With a 2.8-12mm Lens, you have significant zoom capabilities (out to 12mm) or wide angle (2.8mm) as well as anything in between.
Why Do I Need Motorized Zoom?
If you have ever tried to get the focus just right on a manual zoom camera, you know how difficult it can be. With the STH-B5571AFW, you just zoom in, or out to the picture you want, and the cameras Auto Focus automatically gets the perfect focus for you. The 2.7-13.5mm Lens makes this an extremely versatile camera for many installs. You can also control the camera’s zoom function through UTC (Up The Coax). Security cameras that allow for controlling the Zoom at the DVR side make installation easier and also provide additional functionality since the camera can be zoomed in or out at any time. (Also See our PTZ’s for Motorized Pan, Tilt AND Zoom.) Pan Tilt Zoom Cameras!
These two 5MP Bullet Cameras are IP66 Weatherproof and built to last. The cameras have a metal housing, ‘Through The Bracket’ Cable, and several Mounting Options are Available.
Are they Compatible with My System?
The Stoic 5MP CCTV Bullets are 4 in 1 Switchable so they are compatible with most 5MP DVR’s. Currently the most popular and widely used HD Analog Surveillance formats in the USA are HD-TVI, HD-CVI and AHD. The Stoic Cameras will do all of these, and can be set via OSD or Joystick Control on the Camera. They are also capable of CVBS or Standard Analog Resolution for those systems that are a little older. The cameras are also easy to switch from 5MP to 4MP so they can be used on a 4MP DVR as well.
What do you mean by Starlight?
Stoic Technologies Starlight Bullet Cameras see color in extremely low light levels. When other cameras have long since switched to black and white mode, these Starlight Cameras are still providing Color Images! This is accomplished with a Sony STARVIS Back-Lit Sensor that can use a relatively small amount of existing light to produce an image. This is especially beneficial if your business operates in low light situations. If you have ever installed Night Vision Cameras in a Bar or Internet Café, you are probably aware that they are nearly always in Black and White (IR Mode). This is an issue because important details are lost such as the color on somebody’s shirt or the color of a product purchased. With the Stoic Starlight Cameras, color images are still capable down to unbelievably low light levels, preserving important details.
With Starlight Sensor Standard IR at same Light Level
