Frequently Asked Questions

Q: How does the 4-sensor car parking radar system work?

A: The system uses four ultrasonic sensors mounted on your rear bumper to detect nearby obstacles. When you engage reverse gear, the sensors activate automatically and the built-in buzzer emits sound alerts that increase in frequency the closer your vehicle gets to an object — giving you clear, real-time distance guidance.

Q: Is the parking sensor kit easy to install on my car?

A: Yes! The kit is designed for straightforward DIY installation. The sensors connect to your vehicle's 12V electrical system and are triggered automatically when reverse is engaged. The package includes a full wiring harness and installation guide to help you through the process. Most standard cars, SUVs, and vans are compatible.

Q: What is the detection range of the backup radar sensors?

A: The 22mm ultrasonic sensors are designed to detect obstacles typically within a range of approximately 0.3m to 2.5m (about 1 to 8 feet), depending on the size and surface of the object. The buzzer alert frequency increases progressively as the distance decreases, giving you plenty of time to react.

Q: Will the black sensor probes be visible on my bumper?

A: The sensors feature a low-profile 22mm design in a clean matte black finish that integrates neatly into most standard bumpers. They are compact enough to look factory-fitted on most vehicles.
