INTRODUCTION
TSR18 is a 24GHz high performance traffic speed radar that uses the frequency difference between the transmitted radio waves and the return waves to accurately measure information such as target speed. TSR18 adopts microstrip array antenna design, with detection range up to 180 meters, accurate speed measurement, and can distinguish between incoming and outgoing vehicles. Installed next to the road, it can automatically measure the speed of motor vehicles traveling in 1 to 4 lanes.
Features:
- Adopting advanced AI algorithm to effectively identify following cars and large vehicles and prevent missing and re-shooting
- Based on spectrum refinement technology to improve the accuracy of distance and speed measurement
- Vehicle capture position within ±0.5m, with consistency greater than 99%
- Automatic identification of vehicle direction of travel: incoming and outgoing
- Integrated design, integrated level and angle scale, easy installation
- Strong environmental adaptability, radar performance is not affected by light, dust, rain, snow, haze and other harsh environments
- Simultaneous RS485, RS232, Wi-Fi communication function, convenient configuration parameters
Application:
- Roadside speeding capture, intersection incoming traffic reminder, speed feedback instrument application needs, applied to the highway, ordinary highway, community entrance, school section, practice section and other scenes that need to display vehicle speed

FAQ
TSR10/TSR18 | Camera Not Triggering
Verify communication cable connection and pin configuration
Confirm camera protocol compatibility
Check serial port settings: function selection and baud rate
Ensure "Capture Mode" is enabled in Intelligent Traffic Settings
Validate radar parameters in camera settings:Working mode, Minimum target interval, Detection direction, Sensitivity
TSR10/TSR18 | No Speed Output
Verify radar alignment with target lanes
Confirm installation angle is within ±3° range
Ensure detection distance is within 30m operational range
TSR10/TSR18 | Missed Detections
Recalibrate radar alignment with target lanes
Adjust capture trigger line position
Increase sensitivity if set below threshold (default: 60)
Correct horizontal displacement if biased
