Parameters & Specifications

More detailed information

1. Core Value

Ø Ultra-Slim & Stealth Deployment

Measuring just 69mm × 30mm × 9mm and weighing a mere 32g, the VM90-Light is the smallest in its performance class. This razor-thin design allows for effortless, highly concealed installations in the tightest vehicle spaces.

Ø Optical Tamper Detection

Security you can trust. The device features a built-in optical sensor (light-dependent resistor) on its back. If the tracker is maliciously removed from its mounting surface, it instantly triggers a tamper alert to the platform.

Ø 9V-90V Universal Compatibility & Protection

Designed to operate seamlessly across a DC 9V to 90V range, making it ideal for everything from e-bikes and motorcycles to passenger cars and trucks. It also features 200V reverse polarity protection to safeguard against installation errors.

Ø Intelligent Data & Power Management

Equipped with a 3D 3-axis accelerometer, the VM90-Light uses a smart sleep mode, drawing less than 10mA. During network blind spots, it caches up to 800 trajectory points, uploading them seamlessly upon reconnection to ensure zero data loss.

2. Target Applications

Ø Auto Finance & Leasing: (Ultimate concealment, optical anti-tamper alerts)

Ø E-bike & Motorcycle Tracking: (9-90V wide voltage, ultra-compact size)

Ø Corporate Fleet Management: (Mileage statistics, speed monitoring)

2. Anti-Dismantle Sensor Tip (Crucial)

The back of the device has a Light Sensor.
Installation: You must install the light sensor side facing inward/downward into a dark area.
Trigger: Once installed, if the device is removed and light hits the sensor, it triggers the alarm. Do not test this feature repeatedly indoors unless you turn off the alarm first.

3. Troubleshooting

Offline? Check SIM card balance and if the vehicle is in a basement.
Drifting? Ensure the 'Static Drift Suppression' is enabled (default is ON) to stop GPS jumping when parked.
