As with any industry, technology in CCTV has made rapid advances, and there are now some very clever tricks that our systems can do for you.
Tripwire, or Line Crossing, sets a virtual line in the field of vision of a camera. If an object moves from one side of that line to another, it triggers a reaction. For instance, many retailers use this technology to monitor how many people enter their shops – the reaction that is triggered is to add another customer to the count. It’s also used to monitor boundaries – when an object crosses the line from the safe side to the secure side, an alarm is triggered.
Area Intrusion is similar, whereby we set up your system with a virtual box in the field of vision. When an object moves into the box, the reaction is triggered.,
Loitering Detection and Unattended Object Detection are also very similar technologies – they both detect when there has not been a change, or a significant change, within a defined area on screen, for a defined period of time. The former is primarily used to deter anti-social behaviour, whilst the latter can help with crime prevention.
Facial Recognition allows a system to compare a face detected by the camera with a face in a database. This has myriad uses:-
- Access Control – check that the face of a person attempting to use an access control fob matches that of the person to whom the fob was issued
- Retail – detect the presence of known shoplifters
- Sports – detect the presence of people with banning orders
