Chinese airport

In China, Changchun Longjia International Airport saw a total volume of almost 13 million passengers in 2018. It needed an additional terminal. Its Terminal 2 building covers an area of 55,600 square metres. Opening in October 2018, Terminal 2 has been serving domestic flights from 22 airlines, while international flights are now in Terminal 1.

The airport wanted to integrate video security, intrusion detection, public address and access control for staff within one platform while meeting government security guidelines. Since 2017, these laws include mandatory storage of all video data for 90 days, which puts a premium on adequate data storage in a space covered by 1000 cameras. Given the scale, managers wanted to work with a one-stop provider for delivery on time. Bosch received the contract based on a track record the firm says of large-scale airport security installations and the ability to connect all components – video security, intrusion alarms, access control and public address systems – on its Building Integration System (BIS).

Bosch installed nearly 1500 cameras inside and outside Terminal 2, including the Autodome IP 4000i and IP 5000i and Flexidome IP 6000 VR series. All IP-based cameras are centrally managed on the Bosch Video Management System (BVMS) and can trigger automated alerts via video analytics. Outdoor cameras can withstand temperatures down to minus 40 degrees C, suitable for Changchun’s harsh winters. And to maintain a small data footprint while meeting the legal obligation for 90-day data storage, the cameras use H.265 compression, thereby reducing bandwidth to 2 Mbps and storage space by up to half it is claimed compared to other cameras.

“The reduced bandwidth leading to a fewer number of storage cabinets in the server room was a major reason why our client opted for the Bosch solution,” said Mustaine Hu, Technical Support Manager at Bosch Building Technologies.

The Building Integration System (BIS) supports unified management of access control for airport staff at nearly 350 doors. A mix of card reader and video security cuts the risk of non-employees accessing critical areas with a stolen card and lets in those authorised, without extra screening. A public address system allows security staff to broadcast real-time announcements via more than 1200 ceiling loudspeakers, for controlled evacuation in an emergency. The PA sounds alarms triggered by connected intrusion sensors.
