Description
There is a specific anxiety that comes with parking a motorcycle in an unfamiliar city, or leaving a work van loaded with tools overnight. It is not paranoia — it is the absence of information. The Sentinel exists to close that gap: a 4G GPS tracker that tells you, in seconds, exactly where your vehicle is, where it has been, and the moment it moves without permission.
Under its compact 96 x 72 x 35 mm shell sits a 20-channel GPS receiver with five-meter accuracy, a 4G LTE modem with a free SIM card included, and a 7,500 mAh battery engineered for endurance — up to 30 days of real-time tracking on a single charge and 15+ days in power-saving mode. The TrackerOne app (iOS and Android) delivers one-tap location, custom geofences of any shape with instant movement alerts, and 270 days of route history playback, so a fleet manager or a worried owner can reconstruct exactly what happened, minute by minute. The strong magnetic housing attaches in seconds and detaches just as fast, with no wiring, no installation and no trace.
Security is not about locks. Locks are defeated; information is not. When a vehicle can report its own position, its own history and its own abnormal movement, theft stops being a mystery and becomes a recoverable event. The Sentinel turns your vehicle into its own witness — and turns worry into the quiet confidence of knowing.
The car you love should never be the car you worry about.

Frequently Asked Questions
Q: Do I need to buy a SIM card separately?
A: No. A free SIM card is included with the device. After you activate a service plan, the device appears online in the TrackerOne app within 5-10 minutes of acquiring a GPS signal.
Q: How much does the service plan cost?
A: Plans vary by region: from $8.99/month in Europe, $12.99/month in Australia and the Middle East, and $21.99/month in the US. Annual plans bring the cost down to as little as $5.83/month, and multi-month bundles save more.
Q: How long does the battery last?
A: In real-time tracking mode the 7,500 mAh battery supports up to 30 days of standby; in power-saving mode it runs at least 15 days. You can adjust the reporting interval to extend battery life further.
Q: Can I set alerts for when my vehicle moves?
A: Yes. The TrackerOne app lets you draw custom geofences of any shape around your vehicle; any entry or exit triggers an instant alert to your phone.
Q: How accurate is the location?
A: The 20-channel GPS receiver delivers up to 5 m accuracy in open-sky conditions, with unlimited tracking distance worldwide.
Q: Does it work on motorcycles?
A: Yes — the compact size and strong magnetic mount make it ideal for motorcycles, scooters and ATVs, as well as cars, trucks, trailers and boats.
Q: Can I track multiple vehicles with one account?
A: Yes. The TrackerOne app supports multiple devices under a single account, which makes The Sentinel a practical choice for families with two cars or small fleets. Each device reports independently, and you can name and locate them individually.
Q: What happens if the device is removed from the vehicle?
A: Because the unit is fully magnetic and self-powered, it keeps reporting its position even if it is removed and hidden elsewhere. Combined with the movement alerts and history playback, this gives you a strong recovery trail whether the vehicle is moved or the device itself is relocated.
Q: Is the tracker waterproof?
A: The housing is sealed for outdoor vehicle use and withstands rain, humidity and the vibration of daily driving. For permanent installation, we recommend a dry, concealed location such as under a seat or inside a fairing.
