Bharat Electronics Limited (BEL) is in the process of revamping the security set-up at the Parliament with its CCTV surveillance system with video analytics.
A model of the system is on display at the defence pavilion in the ongoing Trade Fair at Pragati Maidan.
The new surveillance system will involve installation of more CCTV cameras in the Parliament complex. A three-dimensional (3D) map of the complex will be created from images generated by the cameras, explained Manish K Chourasia,deputy engineer at BELs Navi Mumbai facility,which has developed the system.
Chourasia did not disclose the number of cameras to be installed,or details of the contract.
According to him,the system is designed to be more intelligent than conventional ones interestingly,these cameras will not record all that they see.
A crime is typically five minutes long,and sometimes day-long footage will have to be reviewed to identify these five minutes, Chourasia said. The cameras,therefore,are designed to record only aberrations.
Chourasia said the move will save time,manpower and memory. Since the system identifies potential trouble on its own,it would thus avoid the need for multiple individuals monitoring all cameras at the same time,he said.
A camera will start recording when it notices movement towards a restricted zone,or when movement occurs against the stipulated direction on a one-way stretch, Chourasia said. It can also be designed to spot unclaimed bags in a crowded area or spot sharp changes in light conditions at night.
When such aberration is spotted,an alarm is raised at the central monitoring station,unknown to the intruder,he said. At the same time,a recording of the event pops up in the main control screen,with the suspicious activity encircled in red.
Not all alarms turn out to be a hazard, Chourasia said,so the operator is asked whether he/she wants to handle the event first. If the operator is convinced the alarm is not false,he/she can request for a 3-D map of the concerned area.
The map will provide the exact location of camera and location of the nearest security post.
The annual maintenance contract for the security set-up has been awarded to BEL-Navi Mumbai.
Chourasia did not reveal the full range of applications due to security reasons.
In new system
* Camera designed to record only aberrations
* Starts recording when it notices movement towards a restricted zone,for instance
* Alarm raised at central monitoring station when aberration is spotted
* A recording of event pops up in main control screen,with suspicious activity encircled in red
* Operator can request for 3-D map of concerned area
* Map will provide exact camera location,and location of nearest security post
The move will save time,manpower and memory
