IndigoVision Deploys Largest IP Video System In Asia At Delhi International Airport
IndigoVision’s integrated end-to-end IP Video solution has been used for a more than 3,700 camera surveillance system in the new Terminal 3 at Delhi International Airport (DIAL). The project is believed to be the largest single installation of an IP video system anywhere in Asia.
The new terminal was built as part of the massive infrastructure development for Delhi ahead of the highly successful 2010 Commonwealth Games. Delhi is India’s second largest airport and with the recent expansion can handle 34 million passengers per year.
Airport’s create one of the most demanding security environments, with multiple operators from different agencies and departments requiring access to live and recorded video 24/7, from different locations in and around the terminal building. This requires the surveillance system to be flexible, reliable, easy to use, and low maintenance in order to avoid any delays or problems in the operation of the airport. IndigoVision’s distributed server-less IP Video architecture provides the airport with such a solution, being scalable, resilient and through a virtual matrix easy to operate, even for a project of this scale.
Commenting on the success of the project, an Operations Manager at DIAL’s state of the art AOCC control room said, “The Control Room and all 3,700 cameras run extremely well and without any problems. The video quality is excellent and the software is easy to use by our operators. Due to the high number of cameras and amount of activity in the airport, it was important to have a system that provides a smooth user experience and no downtime – IndigoVision has exceeded all of our expectations.”
IndigoVision’s ‘Control Center’ Security Management Software is at the heart of the system and is used by operators throughout the airport. IndigoVision’s distributed architecture allows ‘Control Center’ workstations to be used at any point on the network.
The software provides advanced Identification Authentication Management (IAM) features, which ensure only the operators with the correct permissions are allowed to access the video. This allows the various cameras to be partitioned into groups for various departments and agencies. For added security, 120 cameras for the Immigration department have been allocated to a separate site database, with recording on their own dedicated Network Video Recorders (NVRs).
A total of 80 ‘Control Center’ workstations have been installed in three separate control rooms; the Airport Operation Control Centre (AOCC), situated in the terminal; the Airport Security Building (ASB), located off-site 850 feet away; and in the Air Traffic Control (ATC) centre, where aircraft ground movements are monitored. The AOCC, which is the main monitoring centre for the airport, boasts the biggest video wall in Asia. The 32 X 16 foot wall holds twenty-eight 70” screens that display the information inputs from all the airport departments through live camera feeds. Each screen can display up to 25 multiple camera images, providing the AOCC with the capacity to display 700 images at one time.
Monitoring so many cameras in such a complex building is a major task for any security team. DIAL has extensively deployed IndigoVision’s real time analytics, which run at the network-edge in IndigoVision IP cameras and encoders, to help operators improve efficiency and incident response. Analytics are configured to create alarms when certain conditions in a camera scene are met, automatically alerting operators to potential problems.
Examples of the analytics deployed include Virtual Tripwire for alerting entry into secure areas and Abandoned Object, used to identify luggage stuck on a conveyor belt in the baggage handling system. Operator efficiency is further enhanced by the use of IndigoVision’s integration modules to interface to the access control system (over 3000 card readers) and the series of travelators and escalators (using an OPC interface). Again the operators are automatically alerted if for example, a forced entry alarm is triggered by a door or an emergency stop button is pushed on an escalator.
Another area that is vitally important for the airport is the quality and reliability of recorded video; operators and law enforcement agencies need to rely on high-quality evidential video to aid investigations and cannot afford to lose video through missing frames or unreliable equipment. IndigoVision is unique in the ability to deliver very high-quality full-framerate video with a guarantee to never drop a frame under any circumstances. This coupled with its fault-tolerant recording solution provides DIAL with the archive security they require. The airport uses a total of 57 IndigoVision 10TB Windows NVRs for recording video continuously for 30 days from all of the cameras. Ten of the NVRs are used as backups, automatically recording video from any of the primary NVRs that go off line.
