Metro operations are increasingly relying on IP-based CCTV systems to ensure passenger safety and higher efficiency. The need for effective video surveillance has led to increased investment in onboard IP CCTV systems with a greater number of cameras and NVR computing platforms being deployed in more and more locations throughout the train.

With increasing deployment of IP cameras and computers onboard a train, there is a corresponding increase in the performance, reliability, and design requirements for IP cameras and computers. These requirements include more cameras with different form factors and easy installation for different locations on the trains; crystal-clear image quality in a wide dynamic range of dark and light environments; high performance video streams for smooth video surveillance; and vibration, humidity, and dust resistant devices for harsh onboard environments.

Wide range temperature tolerance

Moxa’s IP-based CCTV systems offer compliance with essential sections of EN 50155 and EN 50121-3-2; VPort P06-1MP-M12-T IP camera operating safely in -40°C to 70°C temperatures without fan or heater, and compliant with the highest EN 50155 TX temperature criteria; computers with SafeGuard technology using passive heat exchange to keep cool in high temperatures; and Moxa’s Intelligent Heat Solution for operating in extremely low temperatures, guaranteeing quick booting with an automated, PCB-integrated hardware utility that will postpone system initialisation as the hard drive is heated up.

Superior image quality under any lighting conditions

Video surveillance can be impacted in a train as the lighting conditions onboard vary wildly when it passes through a variety of different environments, including tunnels, open air, and shade. IP cameras must therefore capture a wide dynamic range of dark and light, as well as reduce noise and motion blur to continuously provide crystal clear image quality. Moxa’s IP cameras capture sharp full motion video images at HD resolution, and use advanced image technologies such as DNR (Digital Noise Reduction), BLC (Backlight Control or Black Level Control), and WDR (Wide Dynamic Range) to provide clear pictures in any lighting condition or environment.

Optimal streaming performance in low-bandwidth environments

A major component of IP surveillance systems that affects both the network and video performance, video streaming in Moxa’s systems occurs via custom technology to deliver consistent video quality without overwhelming network resources. Moxa’s IP cameras deliver up to three independent video streams (two H.264, one MJPEG) simultaneously, with CBR Pro technology stabilising the bit rate and guaranteeing that the system will maintain consistent video performance even in low-bandwidth environments.

Moxa’s video streaming capabilities include DynaStream to control video frame rate for system and network efficiency; advanced CBR Pro to secure video stream transmission to provide better image quality by eliminating dropped packets; and multi-stream video supported for different application requirements.

Advanced Ethernet train backbone

Given that it takes a lot of bandwidth to deliver the advanced technology, rich audio, and video data used in an onboard CCTV system, Moxa’s EN 50155 managed Ethernet switches create future-proof Turbo Ring networks that can deliver large amounts of video data. These solutions meet increasing demands, have backup links that quickly respond to link failures, and also improve surveillance functionality without imposing additional operational costs.

Moxa’s EN 50155 managed Ethernet switches feature Dynamic Ring Coupling technology that excels in inter-consist network redundancy. When train carriages are reordered, Dynamic Ring Coupling technology reduces configuration time and potential human error, ensuring high reliability and efficiency in everyday operations.

Secure and reliable disk access under extreme vibrations

Maintaining the integrity of the video data and preventing any data loss are priorities for NVR computers. Moxa’s SafeGuard technology secures the data on NVR computers and rugged NAS devices with intelligent protection against data corruption, even during extreme vibrations or shocks.

Wide selection for all onboard locations

Moxa provides a variety of EN 50155 IP cameras to suit different applications, carriages, and installation environments in onboard CCTV systems.

Moxa also provides diverse NVR computing platforms and NAS devices to fulfil various customer demands. Moxa’s onboard NVR portfolio includes solutions for driver car NVR, passenger car NVR, NAS, or gateway applications. Options are also available for different performance levels, device role, functionality, and form factor.

Easier maintenance via industrial auto configuration technology

Onboard CCTV systems operating in dynamic, complex network environments must maintain high availability and minimise the amount of time spent on maintenance for the railway service to stay on schedule. Moxa’s FIL (Flexibile, Location-based, Intelligent) technology improves system availability by making maintenance and replacement of network devices faster and more consistent. Moxa’s railway devices can automatically determine their own device and network settings based on where they are attached to the network, facilitating quick and error-free device maintenance and replacement, even when the maintenance team is unfamiliar with IP network technology.
