Eight-sensor layout
The body lists four front and four rear sensors with brake/reverse activation logic.
R300 · ultrasonic warning system R300 is a 12/24V ultrasonic obstacle-warning system using eight sensors for configured front and rear zones. The current body lists a 0–5m range, 0.1m detection accuracy and 0.14s response, but those values require confirmation under the intended mounting and test conditions. Buyer overview The body lists four front and four rear sensors with brake/reverse activation logic. The current body provides this project range, not a universal guaranteed range. Alarm behavior and compatible I/O or RS232 are listed for system integration. The current record lists commercial-vehicle power input. System fit Confirm vehicle or site layout, sensing or camera zones, alerts, power, interfaces, storage or network and operator response before installation. Document target types, required zone, mounting, environment, test method and acceptable false-alert behavior. Confirm power, connectors, I/O, display or controller, storage, network, calibration and maintenance scope. Current structured record Use the structured record as the current baseline. Conflicts with older body copy are disclosed below. Preserved from the original page Existing product video Commissioning planning Test zones, target response, alarm timing, nuisance alerts, visibility or ranging, storage/network workflow and operator response before rollout. Example applications Commission rear sensors around bumper geometry, ground clearance and target conditions. Validate brake-trigger logic, front sensor placement and nuisance-alert behavior. Confirm sensor count, harness, monitor/buzzer, controller, power and alarm thresholds. R300 is an ultrasonic warning aid, not a collision-prevention guarantee and not a substitute for direct observation. Range, 0.1m accuracy and 0.14s response depend on target material, angle, mounting, weather, contamination and test method. Structured temperature is -30°C to 80°C while the body says -40°C to 85°C. The structured video-resolution field appears unrelated to ultrasonic sensing and should not be used to define radar performance. Buyer questions The body lists 0–5m. Confirm the required zone and test it on the actual vehicle. The body describes four front sensors activated during braking and four rear sensors during reversing. No test conditions are supplied. Treat it as a listed value requiring project validation. The body lists 0.14s, but real alert timing depends on configuration and conditions. No. It is described as an ultrasonic warning system; a structured video-resolution field appears unrelated. Sensor placement, ground clearance, activation logic, alarm thresholds, controller, buzzer/display and false-alert behavior. Confirm the complete project AlwayCare can review sensing or camera layout, alerts, interfaces, storage, network and commissioning requirements.What is R300?
