Overhead Catenary Work Vehicle Video Monitoring System

The overhead catenary work vehicle video monitoring system is our company’s latest developed high-definition video monitoring system. The onboard video integrated unit is installed inside the driver's cabin of the railway overhead catenary work vehicle. It integrates an NVR motherboard, hard drive, DC power module, switch module, and a 10.1-inch display screen, providing an all-in-one device for HD recording, storage, and playback, based on the N9M software platform. Each unit supports access to 8 IPC channels for recording and 1 Gigabit network port for cascading. The built-in 4G module and GPS positioning module allow video monitoring of road conditions, the driver’s cabin, and the workspace platform of the overhead catenary work vehicle. With the 4G and GPS features, it can achieve real-time positioning and the uploading, storing, and transmission of image data.

System Features

- Integrated design of the host and a 10.1-inch touch display, supporting both touch and mouse input.

- Each host supports 8 channels of high-definition camera input and 1 Gigabit network interface.
