The Ningbo city bus mobile surveillance project, one of the transportation installations in China, covers more than 3,600 buses belonging to 14 transportation companies in Ningbo city.
The Ningbo Transportation Department faced many of the common problems with security on their buses. They needed to protect their assets and provide passengers and drivers safety and security. Their security system needed to provide evidence in the event of theft or injury, helping to settle disputes between passengers and staff.
The surveillance system had to support high-quality video playback and store video data tracing back to two weeks ago. Antishock technology was adopted to ensure normal function of the mobile surveillance system when the bus is in motion. Hikvision provide a mobile solution which consisted of the mobile DVR, backup device and colored dome camera to meet these requirements.
In this elegant mobile surveillance system, four Hikvision cameras were installed separately in the windshield, carriage, front door and exit of each bus providing surveillance coverage of more than 90 percent of the bus.
The camera installed in the windshield mainly monitors whether the drivers go through a red light which would lead to traffic accidents. The camera fixed above the driver monitors whether passengers enter the bus without tickets. The camera in the middle of the bus monitors the security conditions like theft or dispute throughout the bus and the camera at exit keeps an eye on the passenger behavior getting on and off the bus.
This system creates a deterrent effect on criminals as well as unruly passengers, effectively ensuring the safety of the drivers, passengers and their property. In addition, if there are complaints about drivers from the passengers, or dispute between passengers, the related video footage can be retrieved and viewed for reference.
Different from mobile surveillance systems in other cities, the Ningbo city bus surveillance system delivers a high-quality video stream. Using the H.264 video codec, the Hikvision mobile DVR supports real-time viewing and playback with the resolution of up to 4CIF. Moreover, the color dome camera delivers horizontal resolution of 480 TVL, and it also features color and B/W auto switch, ensuring high image quality for 24/7 monitoring.
“As more than 3,600 buses are equipped with surveillance products, it's unrealistic to pay attention to the on-site status of each bus simultaneously,” said Chongguan Jin, VP of Scientific and Information Department in Ningbo city public transportation head office. “In addition, the real-time video transmission means higher cost. So we chose to store the video data locally for playback and retrieving instead of real-time monitoring in this project at moment.”
To realize high-capability local storage, the Ningbo transportation department chose the hard disk drives with the capability of up to 750 GB each, which can store video data at least 15 days. The Hikvision mobile DVR backup device was also used in this project for video data backup.
“To date, this project has covered most of the public bus routes in Ningbo city,” said Jin. “After evaluation of the products' utility, stability and reliability by actual use, Hikvision's products have proven to be superior to the surveillance products that have been used in the buses of other cities in China.”
"The video monitoring system created by Hikvision has improved the security of Ningbo bus transportation routes and dramatically decreased the rate of crime or illegal action on our buses,” said Dezhi Zhu, GM of Ningbo city public transportation head office. “The safety of passengers and their property was ensured, and the service quality of transportation companies also has had a positive change accordingly."
