Electop 120dB Car Alarm System with Vibration Sensor & Sound, Car Security System Anti-Theft Device Car Alarm with Wireless Remote & Led Light for Cars, Trucks, Suvs

What It Is

This is a 120dB car alarm system with a vibration sensor, two wireless remotes, and an LED indicator light, designed for cars, trucks, and SUVs—not lawn mowers. It’s intended as a general aftermarket anti-theft security device for 12V DC vehicles.

Fitment & Compatibility

• Vehicle type: Works on any 12V DC negative-ground system (most cars, trucks, SUVs, and some motorcycles or boats). Not compatible with 6V or positive-ground systems.
• Wiring required: Hardwired into your vehicle’s electrical system (requires basic wiring skills). Not plug-and-play for most mowers.
• Mounting: Vibration sensor must be mounted to a solid, non-moving surface (e.g., chassis or frame). Not suited for plastic or thin metal panels that vibrate excessively.
• Obstacles: Very few lawn mowers have a standard ignition or door trigger circuit, so the alarm’s door/trunk trigger wires may have no practical use unless you add switches or sensors.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to connect power, ground, and optional trigger wires. No harness or adapter included.
• 120dB rating: Loud enough to deter theft, but sound quality is buzzy, not a true siren tone.
• Remote range: Claimed 100–200 feet, but real-world range is often shorter, especially through metal mower decks or engine blocks.
• Common gotcha: The vibration sensor is sensitive—false alarms from wind, rain, or even a passing truck are common unless you adjust the sensitivity screw (included) or mount it on a vibration-dampening pad.

Should You Buy It

If you’re looking for a cheap, loud alarm to protect a car or truck, this works decently for the price. For a lawn mower, it’s overkill and under-adapted—false alarms from engine vibration and weather will annoy you, and wiring it into a mower’s 12V system (if it has one) is a hassle. You’re better off with a simple motion-activated lock or a dedicated mower security device.
