Park with Confidence – No Drilling Required

The Shunmaii Electromagnetic Parking Sensor Kit is the easiest, most discreet way to add reverse backup radar to your car, truck, RV, or minivan. The invisible antenna mounts inside your bumper with simple peel-and-stick tape — no holes, no drilling, no permanent modifications. A high-output piezo buzzer alerts you as you back up, so you can park safely every time.

Made in Mainland China.

How It Works

The electromagnetic sensor detects obstacles behind your vehicle and signals you with progressively urgent beeps as you get closer:

🔔 Long interval beep — obstacle approx. 0.5–0.8 m away
🔔🔔 Short interval beep — obstacle approx. 0.3–0.5 m away
🔔🔔🔔 Continuous beep — obstacle less than 0.3 m away

Frequently Asked Questions

Q: Does this electromagnetic parking sensor really require no drilling?

A: Yes! The sensor antenna uses peel-and-stick foil tape that attaches to the inside of your bumper. No holes are drilled into your vehicle, keeping your bumper looking factory-fresh. The entire system is invisible from the outside.

Q: What vehicles is this backup radar kit compatible with?

A: This kit is compatible with virtually any vehicle that runs on a 12V DC electrical system, including cars, trucks, RVs, and minivans. As long as your reverse lamp runs on 12V, this electromagnetic parking sensor kit will work.

Q: How accurate is the buzzer alarm distance detection?

A: The system provides three distinct alert zones: a long-interval beep from 0.5–0.8 m, a short-interval beep from 0.3–0.5 m, and a continuous beep under 0.3 m, giving you clear, real-time distance feedback as you reverse.

Q: Is any maintenance required for this parking sensor?

A: No maintenance is needed. Because the antenna is installed inside the bumper, it is protected from dirt, rain, and car washes. There is no external sensor to clean or replace.
