It is estimated that 70 percent of the city’s residents use buses to travel within the city. To ensure the comfort of passengers and drivers alike, the Public Transit Branch of Shenzhen Public Security Bureau decided to install security cameras on all the buses in Shenzhen, to promote safety and discourage thieves, including pickpockets.
Pixim-Powered Coship cameras meet the challenges
After evaluating available video cameras for on-bus security, the Public Transit Branch of Shenzhen Public Security Bureau chose Coship™ CS66-52CT WDR [Wide Dynamic Range] Dome Cameras, powered by Pixim® Digital Pixel System® technology.
Traditional CCD video cameras are unable to “see” well when lighting conditions are less than optimal. But Pixim-Powered cameras such as the Coship Wide Dynamic Range Dome Camera perform well regardless of changes in lighting, making them ideal for providing security aboard buses.
Pixim’s patented Digital Pixel System technology revolutionizes the way video cameras capture and process images. Pixim’s is the only video image capture technology that employs hundreds of thousands of pixels, each of which acts like an individual self-adjusting camera. Using this all-digital system, Pixim-Powered cameras can efficiently capture the whole picture, regardless of lighting condition or location. Pixim-Powered cameras offer the highest total resolution, natural color and clarity available, and they accurately capture highlights and lowlights in the same scene.
The Shenzhen bus project uses the Pixim D1400 Mobile chipset, which is specially designed for embedded and hidden security applications, where it is not possible or desirable to adjust camera settings. The new Pixim Orca chipset also brings Pixim’s award-winning image quality to environments that experience vibration, such as buses.
The uncomplicated “fix, focus, forget” operation of cameras using the cost-effective D1400 makes this new Orca chipset ideal for use in solid-state wide dynamic range cameras in environments where moving parts, such as a DC Iris and other auto-iris lenses, would be impractical or cost-prohibitive. In fact, Pixim has the only wide dynamic range chip technology that does not require a DC Iris lens.
In addition to using the Pixim technology, the Coship cameras chosen by Shenzhen Transit Group offer the compact dome shape, vibration tolerance and anti-vandal, hard plastic shell needed to operate effectively on board Shenzhen’s buses.
Clear identification means peace of mind
So far, approximately 2,000 Shenzhen buses have Pixim-Powered Coship security cameras installed facing the front door, to capture images of everyone who gets on and off the bus. Passengers can be clearly identified as they step onto the bus, pay the fare and move to a seat – and again as they exit the bus at the end of their journey.
As the buses move throughout Shenzhen, day and night, the Pixim-Powered security cameras automatically adjust to whatever lighting conditions are present. If someone misbehaves – for instance, tries to board without paying the proper fare, or tries to steal from another passenger – authorities will have an accurate picture of the person, which can be used for identification and, if appropriate, prosecution.
In addition, the Shenzhen Transit Group believes that by knowing security cameras are recording accurate pictures of them, potential misbehavers will be deterred from their actions. In either case – as a deterrent or as evidence – the Pixim-Powered Coship security cameras are providing valuable security services for the bus-riding people of Shenzhen.
Due largely to the success of the Shenzhen bus installation, Coship also is providing Pixim-Powered security cameras for various buildings and banks around the city of Shenzhen, and the camera company plans to install Pixim-Powered wide dynamic range dome cameras on more than 10,000 buses in other cities in China.
