Often times, surveillance plays an integral role in any security apparatus. It is necessary for so many different business reasons, as well as personal ones. For instance, having a surveillance system is important for retailers, for the service industry, and for your homes security. It is applicable to so many situations for good reason; it is very effective, and offers a lot of insurance against failings in any other part of your security apparatus.

For any one of these situations, the requirements of a surveillance system can deviate slightly, making the standard surveillance model more or less suitable for the situation. Because of this, making sure that you have a system which is fit for purpose requires you to choose a specific surveillance system for your requirements. This could mean having a high tech system, which is better able to compile information, store recordings, or even recognise individuals. We can see this taken to the extreme with surveillance systems in big casinos, which are well known to monitor the body language of the people playing, helping the staff to determine if somebody is cheating and needs to be banned. Understanding your requirements of the system is the first step towards making an informed decision.
