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.

Q1: Is Baroxon radar easier to install than traditional ground loops in London projects?
Absolutely. Traditional ground loops require road cutting which is time-consuming and prone to damage from heavy rain. Baroxon radar can be mounted directly on the barrier gate housing, saving installation time and maintenance costs for projects in London, Manchester, or Derby.
Q2: Can the detection distance be adjusted for narrow toll booths or parking exits?
Yes, the Ba-79G-PRO features an adjustable detection distance (0.5m-0.7m standard, configurable via Bluetooth) to prevent false triggering from adjacent lanes or pedestrians, making it ideal for mall parking and residential barrier gates.
Q3: Does the radar support all types of UK barrier arms?
Yes, it works perfectly with 90° Folding Arms, Fence Arms, and straight Boom Gate poles. It provides high-reliability anti-drop protection for vehicles ranging from motorcycles to large trucks.

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.
