By Edward J Primeau 2010As a video forensic expert, I have seen almost everything when it comes to Closed Circuit TV. Some of it is very disturbing, but much of it is benign — from the lady whose ex-husband is stalking her, to the bank that just captured a robbery on video. Understanding CCTV systems has become part of the video forensic examiner’s job because a majority of video evidence is made on CCTV systems. In the following article, I will give you my tips, from a forensic perspective, on CCTV.Imagine this. You are the proprietor of a convenience store. Last night at 11:06, you rang up a customer’s Snickers bar and a Jumbo Slurpee. The customer reached in his pocket, pulled out a gun, and put it to your head, demanding all the cash in the register. Terrified for your life, you gave him the money. Luckily you had a CCTV system and turned the tape over to the t5 fat burners police. The police sent it to a forensic expert because all you could see on the tape was a dark silhouette of the criminal. Unfortunately, the robber’s face and features were unidentifiable.Although CCTV systems can prove to be beneficial for many reasons, they can be useless without some well thought out considerations. My hope is that the law enforcement and legal community will read this article and pass on the information to the businesses in their community.CCTV is a network of cameras hooked to a monitoring system so that various locations or angles can be viewed and/or recorded. It does differ from broadcast television in that CCTV cameras are not openly broadcast through the airwaves. However, some CCTV systems have point-to-point transmissions (wireless cameras) that could be intercepted by someone with the equipment and knowledge to intercept that signal.
