DITRA Luminance Sensor

Modbus-RTU/Wireless luminance sensor and camera for tunnel safety monitoring

The Luminance Sensor is a multifunctional device that integrates both a sensor and a camera, specifically designed for tunnel lighting management, object surveillance, and high-resolution image transmission to a control center. It can be optionally equipped with a night vision system and a light level sensor. This device ensures safety monitoring and surveillance in dark or hard-to-reach areas within tunnels.

The Luminance Sensor communicates with other systems via the RS-485 (Modbus-RTU) interface, while 2G/3G/4G mobile networks enable interaction with the control system.

The unit operates on a

• Durable Die-Cast Waterproof Metal Casing

• Effortless Installation and Programming

• Integrated Power Supply

• Built-in 2G/3G/4G Modem

• Embedded Luminance Sensor

• Automatic Heated Thermo Cover for All-Weather Operation

• Scheduled and Manual Image Capture
