Security in transportation is a major issue in different cities worldwide which majorly contributes to an increase in demand of surveillance systems. In addition, urban transit authorities are under pressure to prevent fatalities due to road and rail accidents, while dealing with the rapidly growing problem of traffic congestion and overcrowding in public spaces. While governments and business establishments, airports, retail stores and city streets are increasingly adopting highly capable 4K cameras, the same benefits of safety and convenience have to be extended to public transportation systems. In addition, businesses also need to track and monitor their on-road vehicles to ensure that each delivery is secure, and on time.
Meeting the present day surveillance requirements of the transportation industry can be an extremely challenging affair. Here we list a few major concerns that fleet operators have.
4K surveillance solutions address the unique needs of a diverse range of transportation environments. Capturing live footage in extreme light and weather conditions is important, which can be used to ensure that the best picture quality is always achieved.
eInfochips has designed various solutions for camera design services including edge devices like 4k transit surveillance cameras, car NVRs etc. that have been deployed in mass transit, collision avoidance and school transport.
In one of our innovative use cases for camera-based surveillance in transportation systems, eInfochips has designed a camera configuration module in firmware design for a US-based client, consisting of H.264 encoding with different bit rates of 8 MBPS and 5 MBPS in front and rear respectively, and a mechanism to enable/disable wide dynamic range (WDR) on the camera and more.
The video storage unit is further mounted on SD cards using a container format to allow video, audio and sensor data to be fused together on a single timestamp (GPS, accelerometer and panic button details), dividing containers into multiple chunks/files, event trigger support for accelerometers and panic buttons, logging of all sensor data and more.
You can find out more details about this interesting use case in this whitepaper on intelligent transportation systems.
