LNKERCO 108dB Car Alarm — Magnetic Vibration Sensor with Remote & Flashing Red Light

LNKERCO's 108dB Car Alarm is a compact, magnet-mounted vibration sensor that emits a loud siren and flashing red light to deter vehicle tampering and signal nearby attention.

This portable anti-theft unit combines a high-sensitivity motion sensor with three selectable volume levels and a visual warning light, giving you a simple, tool-free way to protect cars, RVs, trucks, bikes or luggage. It runs on two common AAA batteries and includes a remote control for arming, disarming and helping you find your vehicle in crowded areas.

How does the alarm detect and respond to attempted theft?

The device uses an accelerometer-based vibration sensor with algorithm filtering to distinguish knocks from strong impacts. On the first trigger it issues a short chirp and flashes the red LED; repeated or stronger vibration activates a continuous alarm cycle to draw attention.

• Three sensitivity thresholds cut false alerts from wind or minor bumps
• Initial 2-second warning pulse followed by 30-second full alarm on stronger triggers
• Flashing red indicator mimics active security systems to deter intruders

What volume options and sound output can I expect?

You can pick from three alarm intensities — 96dB, 102dB and 108dB — to suit different environments. Higher settings are useful for outdoor parking lots while lower volumes work better in busy streets or attached garages where excessive noise is a concern.

• 108dB top-level for maximum attention in open areas
• Middle and low levels preserve neighborhood peace and reduce disturbance
• Adjustable sound profile helps tailor protection to your parking situation

How is the unit installed and powered?

Installation is magnetic: press the alarm onto any metal surface and it stays in place without drilling or adhesives. The unit runs on two AAA batteries, offering weeks to months of operation depending on activity and chosen volume level.

• Strong magnetic base for quick, non-destructive placement
• Battery-powered—no wiring required, ideal for temporary or rented vehicles
• Portable design lets you move it between vehicles or use on doors, bikes, luggage

How does the remote control improve everyday use?

The included wireless remote extends up to about 66 feet, allowing you to arm and disarm the alarm from a distance. It also helps you locate your vehicle in crowded lots with a quick audible/visual check.

• Up to 20 meters effective remote range for convenient operation
• One-button arm/disarm for fast security changes
• Remote-triggered sound aids vehicle location in parking areas

Who is this for: The LNKERCO 108dB vibration alarm suits drivers, RV owners and fleet users who want a no-fuss, portable deterrent for parked vehicles. It's also useful for cyclists, travelers securing luggage, or homeowners seeking a simple door/window alert — anyone needing a battery-powered, magnetic alarm that’s easy to move and adjust for different environments.
