INTRODUCTION
TSR20 Speed measurement radar is mainly used in speed feedback instrument to measure the speed of motor vehicles. When the speed measured by radar exceeds the set value, the speed feedback device will warn the driver through LED flashing (or changing color), to timely remind the driver to pay attention to reduce the speed of driving, so as to effectively reduce road traffic accidents caused by over speed.
Features：
- Small size, light weight, easy installation
- Can cover multiple lanes
- Trigger distance up to 300 meters
- Not affected by weather and light intensity
- Accurate speed measurement ability
Application：
- School Hospital 3D Parking Stadium Factory entrance and exit Road turn Road junction Highway section

FAQ
TSR20 | Firmware Upgrade Failure
TSR20 has two firmware versions:
Type A: RS232 for host communication + RS485 output
Type B: RS485 for host communication + RS232 output
Cross-flashing prohibited - requires dedicated programmer
TSR20 | Speed Measurement Range
Upper limit: 200 km/h (hardware-limited)
Lower limit: 5 km/h (configurable)
False positives from wind-blown debris can be mitigated by raising minimum speed threshold
TSR20 | Indoor Pedestrian Detection Issues
Multipath interference in indoor environments may cause directional filter anomalies. Field deployments exhibit no such issues.
