INTRODUCTION
The TCM811 is a compact 80GHz radar using MIMO+DBF technology for 1.2-150m range and 6-lane detection. It tracks 128 targets, supports lane division, parking queue detection, frequency switching, and angle compensation. Ideal for monitoring large/small vehicles and electric bikes, it’s small, powerful, and easy to integrate.
Features：
- The maximum detection distance is 150m
- Support 1 to 6 lanes
- Capable of monitoring up to 128 targets simultaneously
- Support two capture modes of coming and going
- Easy installation, easy integration
- Free from external interference such as light, dust, rain and snow
Application：
- Traffic flow monitoring and intersection congestion detection

ADVANTAGES
 | Frequency Isolation for Absolute Anti-Interference Utilizes the 80GHz band, physically isolated from the 77GHz band (used by automotive radars), effectively preventing interference from vehicle radars. |
 | Dual-Beam Detection for Multi-Lane Coverage Features near-and-far dual-beam detection, enabling a measurement range of 150m and coverage of 1–6 lanes. Supports distance measurement, speed detection, and precise positioning for up to 128 targets. |
 | Strong Environmental Adaptability Unaffected by adverse conditions such as light, dust, rain, snow, fog, or sandstorms. Provides 24/7 real-time monitoring of road sections. |
