Sales and wholesale of commonly used equipment for electronic police at traffic checkpoints

The electronic police at traffic checkpoints mainly implements functions such as vehicle capture, license plate recognition, network deployment and control, speed measurement, and on-site audio. The communication system adopts a star networking method, that is, a point-to-point structure, one point and one fiber, and each traffic checkpoint is basically a grid. Distributed in a star shape and uploaded to the traffic command center through their respective optical fibers, forming a star optical transmission network. In order to save investment in optical communication channel construction and equipment, TV surveillance images and red light violation records/control information can be multiplexed into an optical terminal and transmitted to the traffic command center. The video can be connected to a large-screen projection system to monitor different intersection conditions. Jiangmen Municipal Traffic Management Bureau uses Tianwei Telecom's multi-service optical transceiver. The middle video interface is mainly used to take pictures of vehicles, and R realizes the control of the on-site pan/tilt. An Ethernet port realizes networking with the center, and the other isolated network port connects to Wanwan. Pixel's high-definition camera and two-way audio realize on-site audio collection and intercom/announcement. If there is a duty point on site, a telephone interface can also be provided to extend the center's telephone switch port to the site to realize internal calls.
