Challenges and Solutions for Efficient CCTV in Road Transportation

Public transportation has been an important focus for city development in recent years to improve traffic management and quality of life. Bus Rapid Transit (BRT) systems are popular thanks to their low cost, high flexibility, high efficiency, and shorter development time compared to railways or MRTs, and have seen extensive development in both South America and China.

The city of Taichung, Taiwan, has invested in six BRT lines that will operate in 20 or more sections of the city. An important part of ensuring that the BRT system works reliably and efficiently is the implementation of a video surveillance system that encompasses every aspect of the BRT line, including stations, buses, and control rooms.

What to Look for in an IP CCTV System

Although IP CCTV video surveillance systems are now commonplace in cities around the world, not all systems are created equal. In particular, to be suitable for use with a BRT system, the IP CCTV system should at least satisfy the following criteria:

  • Produce a clear live video display with high frame rate
  • Support effortless video recording
  • Support real-time video sent from stations to the control room
  • Control room operators must be able to easily locate video data from specific cameras at specific times
  • Have an interface that can be integrated with other traffic control systems

Taking into consideration the hierarchical nature of BRT systems, the best solution for this kind of application is to use a centralized video management interface together with a distributed recording server.

System-Wide Observation

When the entire system is up and running, the CCTV systems in each station should connect with the CCTV system in the control room, with operators in the control room expected to watch live video feeds from cameras installed in each BRT station and along the bus route. In particular, events triggered at any part of the video surveillance system should automatically alert operators in the control room.

In addition to system design and software requirements, another major concern when building surveillance systems for BRTs is the choice of camera. Surveillance camera solutions for BRT systems, unlike residential video surveillance systems, require a variety of camera types to be installed in different parts of the system. For example, whereas mini dome cameras would be used at ticket vending machines, PTZ dome cameras should be used at station platforms. Furthermore, when designing a BRT surveillance system, don’t forget to choose “industrial-grade” hardware with enhanced reliability. General consumer surveillance equipment that carries a 1-year warranty is not really suitable for such applications.

Moxa’s IP CCTV Solution for BRT Systems

Moxa’s IP CCTV solution includes industrial-grade IP cameras and proven large-scale video management software. The system provided to Taichung will be used in the BRT control room as well as at more than 40 BRT stations scattered throughout the city. Products used in the system include:

 

 

The business benefits of using Moxa’s IP CCTV solution include:

  • Sophisticated software solutions: SoftNVR-IA for a full function NVR server, and SoftCMS for centralized video management
  • Complete camera product portfolio with fixed dome, mini dome, and PTZ dome options
  • Industrial-grade MTBF
  • 5-year warranty for fixed cameras and 3-year warranty for PTZ cameras

Industrial-Grade MTBF

Unlike traditional CCTV solutions, Moxa’s cameras feature an MTBF that exceeds 500,000 hours (the actual number depends on the model), which translates into higher reliability. By their very nature, transportation systems generally have cameras installed over a wide area and at remote locations, making it difficult to send technical support engineers into the field to handle maintenance tasks. This is one of the main reasons why it is especially important to use camera systems that have a higher MTBF.

3- or 5-Year Warranty for IP Cameras

Most CCTV cameras on the market provide a 1-year warranty, and some even exclude the camera’s moving parts. For Moxa cameras, the higher MTBF and longer warranty period (5 years for fixed cameras and 3 years for PTZ or zoom cameras) are the longest in the industry. End-users can reduce their total cost of ownership for CCTV systems, and also get the best deal on the market from a system life cycle perspective.
