Product Description

79G 80G 81G Road Gate Anti-Smash License Plate Identification Millimeter Wave Radar Detector Sensor Parking System

An 80GHz millimeter-wave radar sensor for vehicle barrier gates provides high-precision, non-contact detection (0.3-6m range) for anti-smashing and automatic gate lifting. Operating in the 79-81GHz range, these sensors feature IP66 protection, ±45° horizontal beam width, and work well in various weather conditions.

Important Usage Precautions

Please read carefully before installation and use:

In logistics park trailer scenarios, install one radar above and below to ensure complete vehicle detection coverage and eliminate blind spots
Radar installation should not be level with the pole. For cars: install 65cm-75cm from radar bottom to driving surface. For trailers: install 100cm-110cm from radar bottom to driving surface
If radar's front is obstructed by license plate recognition systems or other objects, install on a separate pole to avoid interference
Not recommended for areas with extensive ground covers or large metal plates. Small area covers or tracks may be used (consult manufacturer's technical staff)
Not recommended for sharp turn scenarios or mixed pedestrian/vehicle roads as pedestrians can interfere with detection
In simultaneous vehicle entry/exit scenarios, each vehicle requires a dedicated pole; avoid following vehicles or lingering under the arm
For advertisement arms, barrier arms, or fold arms, optimal installation faces incoming vehicle direction. If not possible, use dedicated poles per vehicle and avoid lingering under arm
Do not power radar using 12V output from barrier gate motherboard; requires independent 12V 1A~2A power supply

Installation Instructions

The radar indicator light should be facing upward and installed vertically on the barrier box.

Installation height for cars: 65cm-75cm from radar bottom to ground
Installation height for large vehicles: 100cm-110cm from radar bottom to ground
Distance between radar and barrier arm: 20cm
