BurookHi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so) -
KiranYes I don’t doubt you. Jutai is one of the most confident companies I came across in China

Product Description
Smart Barrier Gate Radar for Vehicle and Pedestrian Detection
Product Overview
The RD79-6M 79GHz Millimeter Wave Barrier Gate Radar Sensor provides advanced anti-crush protection and trigger detection for parking barrier gates, entrance and exit management systems, parking lots, underground garages, and vehicle access control systems.
This 79GHz millimeter wave radar sensor detects vehicles or pedestrians within the barrier arm zone, enabling safer lifting and lowering actions. Compared to traditional loop detectors or infrared sensors, the RD79-6M utilizes 79GHz LFM-CW radar technology with a 2T4R antenna structure, delivering high distance resolution, accurate target detection, and stable operation in outdoor or complex parking environments.
The radar supports multiple barrier arm types including straight arm, folding arm, fence barriers, and advertising barriers. It features multiple detection modes: anti-crush mode, trigger mode, and inclined-mount trigger mode. With Bluetooth app configuration and RS485 communication, installers can conveniently adjust parameters during project commissioning.

Installation Notes
The radar is installed on the barrier gate cabinet side. Installation requires a Φ17mm opening hole, with horizontal distance from the barrier cabinet approximately 23-33cm, and fixed hole distance from the ground varying according to barrier size.
Recommended installation points:
- Install the radar on the barrier gate cabinet side facing the barrier arm area
- Keep the radar detection area aligned with the barrier arm protection zone
- Set the correct barrier arm type and direction in the app
- Perform background learning after installation and parameter adjustment
- Keep people and vehicles away from the detection zone during background learning
- Save configuration after completing all parameter settings
