Moxa is extending the advantages of IP video surveillance to challenging transit applications with the debut of its new VPort 07-3, an EN 50155-compliant onboard dome camera.
An ideal surveillance solution
Hardened against service interruptions caused by heavy vibration, impact, or water ingress, the new camera is an ideal surveillance solution for light rail, buses, and passenger rail fleets.
Built around a 3MP progressive-scan CMOS sensor, it captures sharp 2048 x 1536 pixel images at up to 20 frames-per-second, leveraging bandwidth-efficient H.265/H.264 and MJPEG compression to support multiple independent streams, while benefitting from Moxa's innovative DynaStream™ and CBR Pro™ network technologies.
Around-the-clock surveillance
VPort 07-3 easily manages scenarios where there are significant variations in light intensity
As trains enter and exit passenger stations, underpasses, and tunnels, lighting can abruptly fluctuate from dark to light. Adding to these challenges, most rolling stock is in continuous operation both day and night.
Regardless of lighting conditions, the VPort 07-3 assures forensic-quality imaging by adopting a powerful combination of Dynamic Noise Reduction (DNR), Wide Dynamic Range (WDR), and an advanced Auto White Balance (AWB) algorithm that resolves lighting challenges and reduces motion blur.
Due to its 100dB WDR, the VPort 07-3 easily manages scenarios where there are significant variations in light intensity within the same frame, ensuring the smallest of details are visible in both bright and dark areas.
Flexible design options
Designs of trains and buses can vary greatly, and all surveillance projects have distinct specifications that need to be met. Versatile Moxa VPost 07-3 cameras are available in a variety of models featuring fixed-focal-length lenses from 2.4mm to 8.0mm, line-in or microphone audio interfaces, and different temperature ranges to help create custom solutions to fit the requirements of any project deployment.
For maximum efficiency and minimal wiring costs, all models support PoE (802.3af) and 24VDC power inputs. ONVIF conformity assures interoperability with third-party devices and software.
Industrial-grade cameras
Moxa VPort 07-3 cameras are compliant with mandatory sections of the EN 50155 Railway Certification and the EN 62262 IK8 vandal-resistant rating. To meet these standards, the cameras have been rigorously tested and approved for rolling stock installation and railway deployments.
This includes being certified to withstand temperature ranges from -40° to 70°C, damaging EMI/surges, vibration, and other environmental pressures common on rolling stock.
Advantages
Moxa VPort 07-3 cameras feature an IP-66-rated metal housing, a PC dome cover with a built-in heater
Moxa VPort 07-3 cameras also feature an IP-66 rated metal housing, a PC dome cover with built-in heater and demister, plus a weatherproof M12 Ethernet port providing reliable connectivity where a standard RJ45 connector would fail.
In addition, there is 8GB of onboard storage to ensure continuous video recording even if recorder connectivity is lost due to a power outage. All these advantages make the cameras an outstanding choice for mission-critical mobile surveillance.
Bandwidth preservation
Because preserving network bandwidth is a pivotal issue in IP deployments, Moxa VPort 07-3 cameras incorporate the company's patented DynaStream™ function, which automatically changes the video frame rate to control network bandwidth budget and ease system management.
Another function, Moxa's CBR Pro™, guarantees no packet loss in limited bandwidth transmissions, ensuring that images will not exhibit the mosaic effect. Advanced network security functions prevent unauthorised access or data hijacking of surveillance video.
