 Bosch introduces ‘event triggered’ video

Bosch Security Systems is introducing new Intelligent Video Motion Detection (IVMD) into its IP network video products to significantly increase the possibilities for fully-automated CCTV surveillance and to reduce demands on bandwidth and storage capacity.
Transmission and storage of continuous video streams during CCTV surveillance puts considerable strain on both bandwidth and storage capacity as well as on the security personnel who have to monitor scenes in which, for the majority of the time, nothing happens. By introducing a more event-based surveillance regime, says Bosch, IVMD ensures that only scenes in which important changes occur are captured, transmitted and stored. Utilizing the increased processing power and intelligence inherent in today’s IP network video products, Bosch’s IVMD essentially makes a series of basic pre-decisions governing scene capture based on parameters set by the user during system configuration.
Up to 16 independent detector fields can be set up for alarm generation. Bosch says the IVMD function also features camera calibration for metric or imperial measurements. This is done via a graphical user interface using a 3D grid to allow objects to be distinguished by their real size, including the addition of perspective relations necessary for reliable size and speed discrimination in all directions. With this function, it is possible to trigger alarms only on objects below or above a specified size, for example just for trucks or cyclists. Or to trigger alarms just for objects travelling below a specified speed, say pedestrians walking on a highway.
