ITRTSC-072B-HS
Dahua Traffic Signal Controller
> Built with a modular design, it is easy to configure, operate and maintain.
> Stable and reliable, it has a standby main control board and power-off protection.
> Supports temperature and humidity reporting, access control, and electricity meter.
> Supports configuring start sequence. Smooth transition mechanism for signal control helps ensure traffic safety at intersections.
> Detects failures such as green conflict, lights off, red and green lights on, and designed with automatic degradation mechanism.
> Offers multiple functions to control traffic lights such as manual control, coordination of all the traffic lights for emergency vehicles, and changing the light to its next status. It can also make traffic lights flash yellow or turn off, and trigger all the traffic lights to turn red.
> Supports configuring special tasks through DSS ASCS client and configuration tool.
> Communicates with various front-end devices and outputs traffic light signals to cameras through the network. It also triggers cameras to take snapshots of traffic violations.
> Supports platform central control by sending data of traffic flow statistics, traffic saturation and lane occupancy to the platform.
> Network storm protection function ensures the normal operation of the device under abnormal network conditions.
