This solution mainly consists of a 7″ 4CH AHD monitor, 3 side view cameras, 1 rear view license plate reversing camera, and a pair of optional wireless video signal transmission receiver boxes.
The components are installed in detail
7 Inch 4CH monitor: mounted on the dashboard inside the cab, the driver is able to view the images from the 4 cameras in real time. The easy-to-use operation of the basic functions ensures that the driver can manage the surveillance system efficiently.
3 Side View Cameras: These 3 cameras are mounted above the upper and lower doors on the outside of the 3-door bus and are specifically designed to monitor passengers as they get on and off the bus. In this way, in addition to ensuring the safety of passengers getting on and off the bus, the driver is able to control the doors more accurately through the surveillance images, effectively preventing the potential risk of passenger entrapment.
Rear View Licence Plate Reversing Camera: mainly installed near the licence plate frame, its function is not limited to rear traffic monitoring. When reversing, the monitor screen can provide a reversing guide line to assist the driver to reverse safely, which improves the convenience of reversing.
Wireless Transmission Receiver Box: Since the monitor and reversing camera are located at the front and rear of the vehicle, we have introduced this optional component in order to solve the cumbersome wiring problem caused by the length of the bus. This pair of wireless transmission boxes is very important. With this pair of boxes, the video signal is no longer transmitted by wired means, but by a more flexible wireless method, thus eliminating the need for complex wired wiring along the entire bus body. In the system, the monitor is connected to the receiver box, and the rear-view licence plate reversing camera is connected to the transmission box, ensuring that the video signal is transmitted steadily and efficiently between the two.
The vision solution for the 3-door public buses was designed to address potential hazards in the operation of public buses. Passengers may face safety hazards during boarding and alighting, especially during peak hours when the crowd is large and the risk of passenger entrapment increases. To effectively monitor this situation, side-view cameras are installed above the boarding and alighting doors of the buses to ensure that the driver can better control the doors with real-time footage, reducing the potential risk of passenger entrapment.
In addition, buses have rear blind spots during travelling and reversing, which may make it difficult for the driver to detect obstacles and traffic conditions at the rear when reversing. To address this deficiency, a rear view licence reversing camera is installed near the licence plate frame to provide a full-screen rear view and reversing guide lines, enabling drivers to perform reversing manoeuvres more safely and reducing the risk of collisions and accidents.
The core objective of this programme is to create a safer and more efficient operating environment for public buses by improving the safety of passenger boarding and alighting through a surveillance solution, while reducing the risk of drivers’ blind spots when reversing.
