12V Vibration Car Alarm Universal Remote Control

12V vibration-sensing car alarm: your vehicle monitored at all times

A compact 12V car alarm that keeps watch while you are away—that is what changes the way you leave your vehicle at night. This all-in-one unit combines the siren and electronics in a single housing, slips under the dashboard or behind a trim panel, and sounds a 115 to 120 dB wail at the slightest suspicious jolt. Were you looking for an easy-to-install car alarm without spending an entire day at an installer's? This kit connects to just two wires.

A discreet alarm unit that no one will spot in the cabin

The round black housing, ribbed on top, is no larger than the palm of your hand. Its shape allows it to fit behind a fuse panel, under the seat, or inside a wheel arch, invisible from the outside. That is precisely the strength of a wireless car alarm of this type: the thief hears the sound but cannot find the source quickly enough to disable it.

The two included remotes, in a two-button key fob format, fit in your pocket without cluttering your keyring. One press arms the system, another disarms it, and the siren confirms each action with a short beep: you always know whether your car is protected, even from twenty meters away, without having to go back and check.

120 dB siren and adjustable shock sensor: the mechanics of this anti-theft alarm

At the heart of the kit is a vibration sensor with adjustable sensitivity controlled directly from the remote, with four levels. Low setting for a busy street where trucks make the bodywork shake, high setting for an isolated parking lot: you adjust it without opening the housing or touching a single potentiometer. In the event of a light jolt, the system first emits a short warning; if the intrusion continues, the siren sounds for a full fifteen seconds at 115-120 dB.

The electronics operate on 12 V DC, the radio frequency is 315 or 433 MHz depending on the kit, and the remotes run on a standard 3 V battery that can be replaced in thirty seconds. A remote-controlled car anti-theft device is only useful if it remains operational for years: here, everything is made of common components.

• Integrated 115-120 dB siren — loud enough to scare off an intruder and alert the entire parking lot
• 4-level shock sensitivity — adjustable via remote control, without removing the housing
• Vehicle search function — the siren beeps to help you find its location in an underground parking lot
• 2 remotes included — one for you, one for the second driver or as a spare
• Universal 12 V power supply — compatible with almost all vehicles with a 12 V battery
• 2-wire installation — positive and negative, plus mounting the housing: nothing more

Installing this alarm on your car: two wires, one screw, that's all

The installation is deliberately minimalist. Connect the red wire to the permanent +12 V, the black wire to ground, then secure the housing in a dry and hidden location. No wiring harness decoding, no intervention on the ECU. The installation of a car alarm of this type takes about an hour with a wire stripper and a little heat-shrink tubing. If you are not comfortable with electrical circuits, a car electrician will install it very quickly, at a minimal workshop rate.

Operating at 12 V makes this kit compatible with the vast majority of passenger cars, vans, and SUVs equipped with a 12 V battery; 6 V or 24 V vehicles are excluded. Before installation, check the available space behind your dashboard depending on the version of your car.

Is a sound alarm really enough to deter theft?

That is the question everyone asks. In fact, the vast majority of break-ins—a forgotten bag, GPS, tools—are carried out in a few seconds of discretion. A 120 dB activation instantly destroys that discretion and makes most opportunists give up. An anti-vandalism car alarm does not replace a mechanical steering wheel lock, but the two complement each other perfectly: one makes noise, the other wastes time.

Order your alarm from a car security specialist

At Becquet Voiture, security equipment is part of everyday life: we select simple, repairable kits that are genuinely compatible with European vehicles, rather than locked systems that are impossible to maintain. Our support team answers in French if you are unsure about a connection point, and our catalog also includes steering wheel locks and central locking kits if you want to build complete protection.
