SmartIR and How to Avoid Issues

At least a few times a week we get a call that normally goes like this:

Customer: I love the cameras in daytime, but at night I can’t see anything at all.

Tech Support: Are you able to send a screenshot for me to take a look at?

Customer: Sure. *Sends photo*

Tech Support: It looks like there’s a bit too much of the wall in your frame. I’d recommend moving the camera to the left just a bit to get rid of the reflection from the wall.

Customer calls the next day to tell me that just getting the wall or other reflective surface out of frame cleared up their issue. I should mention that these calls aren’t ever a bother. We completely understand that this isn’t something that the majority of people would even consider to be the cause of an issue.

A majority of newer CCTV cameras use Smart-IR, or some variant. Essentially it’s an adaptive IR that will adjust the focus of the IR to either foreground or overall image. If you have someone walking up to an older camera in IR mode, there was a chance that the image could be blown out from the over-saturation of light. Smart-IR solves this by adapting the intensity depending on what’s in the frame of the camera, and where it is.

In our first example we have a fairly balanced image. There are a few things in the foreground that are a bit more reflective, but it’s not disrupting the image too much.

 

In this next image, I’ve inserted a piece of paper into the frame. You can see that it’s beginning to affect the image, and the way the camera is picking it up.

 

Here I’ve placed the paper even further in frame, and now the entire background is pitch black. Granted, this is really a bit of a silly demonstration. So let’s go to something more practical.

 

Here we have a camera mounted in a pretty normal position. There’s a bit of the wall in the frame, but nothing that’s really causing the image to be affected. Let’s move the camera a bit to the right and see how the image changes. 

 

I do know that this is an extreme example, but this is exactly how reflective surfaces can affect your CCTV cameras in IR mode. Flooding the foreground with light, and basically removing the background.

As stated in a previous entry, it’s always good to plan your system layout before you start drilling and running cables. Consider where you’re mounting your cameras, and make sure that there aren’t going to be any obstacles you need to plan around. Gutters, soffits, light-colored walls, etc… If you have any of those in frame, adjust your camera and you’ll most likely be in good shape. If you’re still having issues, you’re always welcome to give us a call. If you’re in the market for some new security cameras with Smart-IR, we have a wide selection. Just let us know what your needs are.

IS IT COMPATIBLE?

With advances in CCTV technology, there come some challenges. If you purchased a home or business system more than a couple of years ago, you may have to consider compatibility when thinking about an upgrade. This may seem daunting, but in fact, might be a little easier than you think. Many of the security DVRs that we offer are actually backwards compatible, for the most part. This may not be the case if you’re using an older CAT5 system (don’t worry, there’s a solution for this as well!), but if your aging system uses BNC cable, we’ve got you covered! STOiC, TruView, Watchman, and Samsung are compatible with your existing cameras. So, what does this mean for the consumer? In a word, choice. In a few more words, choice, and an affordable way to upgrade your system in stages. You’re able to upgrade your DVR now, keeping your existing cameras, and over time upgrade cameras to get the full potential out of your CCTV system.

Something else to keep in mind is that if you’re using a system that is utilizing BNC cables, you won’t have to run new cable. This can keep costs way down, and turn it from a job needing a contrator, to something that can be done by many people on their own.

So, what about those who aren’t ready to upgrade their whole system? Yep, there’s a solution there, too! We offer one of the few security cameras on the market that is specifically designed to be a replacement for older SD Analog systems. Not only that, with its 4-in-1 capability, it’ll upgrade with you when you’re ready. The STH-B7300W is a wonderfully rounded camera. Capable of 720p in AHD, TVI, and CVI, as well as CVBS (SD Analog), this can replace everything from Samsung’s SDC-5340 and SDC-7340, to Night Owl, LOREX, and even Samsung’s SDC-8440. What’s better than that? Well… STOiC’s two-year warranty is pretty great, too.

Well… given my long-winded introduction, let’s get to the whole point of this entry. Below I’ve compiled a small compatibility chart. This will be updated from time to time, so check back periodically. One more bit of information for you to think about: the STOiC cameras that we offer are compatible with most systems. Not just the STH-B7300W, but all of our STOiC cameras. When you order, just let us know which system you have (or, using the handy chart below, just let us know which video type your DVR uses). We’ll take care of the rest for you!
