Public transportation is a vital service that millions of people rely on every day. However, it also faces many challenges and risks, such as vandalism, crime, violence, terrorism, accidents, and congestion.
CCTV cameras can help enhance the security and safety of public transportation by deterring and detecting potential threats, providing evidence for investigations and prosecutions, monitoring passenger behavior, and improving customer experience.
Some of the technical points that need to be considered are:
✔ Camera type and location: Depending on the vehicle type, size, layout, and purpose, different types of cameras may be needed, such as dome cameras, bullet cameras, fisheye cameras, dual lens cameras, etc. The cameras should be placed in strategic locations that cover key areas of interest, such as doors, windows, seats, the driver’s cabin, luggage compartments, etc. The cameras should also be resistant to vandalism, weather conditions, shock and vibration, dust and dirt, etc.
✔ Camera resolution and frame rate: The quality of video footage depends largely on the resolution and frame rate of the cameras. Higher resolution and frame rate provide more details and clarity but also consume more bandwidth and storage space. Therefore, a balance between quality and efficiency should be achieved based on the specific needs and objectives of each project.
✔ Video recorder and storage: The video recorder is the device that captures and stores video footage from the cameras. It should have enough capacity and durability to handle multiple channels of high-definition video for long periods of time. It should also have features such as encryption, tamper-proofing, GPS tracking, wireless connectivity, etc. The video recorder should be securely mounted in a hidden or locked location within the vehicle to prevent unauthorized access.
✔ Video transmission and streaming: Video transmission and streaming refer to the process of sending the video footage from the vehicle to a central location or a mobile device for real-time monitoring or remote access. This can be done using wired or wireless networks such as Ethernet, Wi-Fi, cellular data, etc.
✔ Video analysis and management : The video analysis and management refers to the process of extracting and utilizing useful information and insights from video footage using software applications such as video analytics, artificial intelligence, machine learning, etc. Video analysis and management can help to improve the efficiency and effectiveness of public transportation by providing features such as face detection, people counting, line crossing, traffic flow analysis, collision prevention, bus lane enforcement, etc. The video analysis and management should be integrated with other systems such as passenger information systems, public display monitors, driver assist monitors, etc.
