In short: a Baroxon 79 GHz radar sensor replaces the road-cutting loop detector for £85 to £460, detecting vehicles from 0.2 to 8 m with no civil works.
The sensor uses frequency-modulated continuous wave radar with adjustable sensitivity and direction recognition, so it can tell an approaching vehicle from a departing one and will not trigger on a pedestrian walking past the lane. Because nothing is cut into the road surface, the detection point is unaffected by resurfacing, standing water, snow or asphalt repair, which is the most common cause of loop-detector failure on UK sites. Relay and dry-contact outputs work with all common barrier control boards, so the sensor can be retrofitted to an existing gate without changing the controller. Power is 12 to 24 V DC with low consumption, and the IP-rated housing is designed for continuous outdoor use on car-park decks and industrial gates.

Video: Setup and Calibration Process for Baroxon Barrier Gate Radar Sensors
Q1: Is the Baroxon Ba-AX3 compatible with common international barrier gate brands?
Yes, it is highly compatible. The Anti-Smash Radar Sensor from Baroxon is designed with universal interconnection flexibility. It fully supports standard RS485 signals and dry contact relays, making it an ideal upgrade for smart parking facilities worldwide.
Q2: How reliable is the sensor during heavy tropical rain or high-humidity operational conditions?
The Ba-AX3 series features an IP66-rated enclosure and utilizes an advanced 77GHz high-frequency core. This ensures that detection of motorcycles and vehicles remains stable and accurate, even during severe monsoon rains experienced by commercial parking operators.
Q3: What are the main benefits of Baroxon radar over traditional ground-loop detectors?
Traditional induction loops require cutting into asphalt, which increases construction costs and maintenance burdens. Baroxon Smart Radar offers a non-invasive installation that protects your road surfaces, allows for easy wireless calibration via smartphone, and significantly reduces downtime, lowering the total cost of ownership (TCO) for your facility.

Each paragraph below states the test condition, the measured value and the benchmark it is compared against, so it can be quoted on its own.
Test condition: 79 GHz FMCW sensor mounted 1.2 m high at 30° on a wet asphalt lane, vehicles from a 1.2 t car to a 40 t articulated lorry. Result: reliable detection from 0.2 m to 8 m, with direction recognition correct in 100 % of 200 approach/departure passes. Benchmark: an inductive loop is limited to a fixed detection footprint and cannot report direction without a second loop.
Test condition: time from a vehicle entering the detection field to the relay closing. Result: under 50 ms. Benchmark: relay-based detection chains built from a loop detector plus interface card typically total 100 to 300 ms, which matters on high-speed lanes.
Test condition: sensor tested through resurfacing of the lane, standing water 40 mm deep, snow cover and 40 km/h crosswind. Result: detection unaffected in all four scenarios. Benchmark: a loop detector is destroyed by resurfacing and produces false holds on standing water, which is the single most frequent cause of a barrier sticking open.
Test condition: power and signal lines subjected to a 4 kV surge and operation from 12 V DC to 24 V DC at −30 °C and +70 °C. Result: no failure and no drift in detection threshold. Benchmark: unregulated sensor modules that quote one fixed voltage often mis-trigger at low temperature, when supply voltage sags on long cable runs.
Feedback from customers who installed this type of Baroxon equipment.
