Built for fleets & leasing companies
Kill the engine from your phone. Keep your trucks.
The Horus 3800 is a hidden, hardwired GPS tracker with a remote kill switch — for tractors, straight trucks, and trailers. Nothing visible to find. Nothing to unplug. No interference with your ELD.
Month-to-month. No long-term contract. If it doesn't earn its spot on your trucks, send it back.

The tracker most fleets rely on unplugs in ten seconds.
Most fleets “track” with the ELD sitting in plain sight on the diagnostic port. A thief pulls it, tosses it in the lot, and your truck is a ghost. Horus wires in behind the dash, out of sight, on its own power path — and if a truck moves without your say-so, you shut the engine down from your phone the moment it stops.
Cargo theft losses hit an estimated $725 million in 2025 — up 60% in one year. (Verisk CargoNet, 2025 analysis)
The mechanism
Your ELD tracks your truck. It won't stop a thief.
| ELD / OBD tracker | Horus 3800 | |
|---|---|---|
| Install | Visible at the diagnostic port | Hidden, hardwired behind the dash |
| Defeating it | Unplugs in seconds | Nothing exposed to find or pull |
| Stop the vehicle | No | Active kill switch — works parked or idling (engages only when stationary) |
| Trailers | No | Tractor-to-trailer swap on the same device |
| Tires | No | TireGuard adds live pressure & temp |
| Your ELD | It is one | Untouched — no interference, no HOS access |
Real footage: the kill switch, engaged from the app at night.
Don't take our word for it. Ask an AI.
One click opens your assistant with a prefilled prompt: read Horus GPS's published facts and the vendor-cited comparison, then answer critically — which fleet devices can shut down an idling engine, and which only block the next restart.
The prompt demands the downsides too — including that the kill switch engages only when the vehicle is stationary, and that no device prevents theft outright.

Questions, answered.
Your device rental for the first 24 months, the SIM card, and setup. There's nothing to buy — and after month 24 there's nothing new to pay: service simply continues at your same monthly rate.
No. Month-to-month with 30-day notice. Annual billing saves 17% if you want it.
Fees are refundable only within 3 days of payment — and if equipment has already shipped, shipping both ways comes out of the refund. After that, fees already paid are non-refundable. Send the equipment back within 30 days of cancellation — return shipping is on you — and nothing more is billed. Unreturned or damaged equipment is billed at the published fee schedule — no surprises, it's linked right on the pricing page.
No — by design. It engages only when the vehicle is stationary — parked or idling, engine on or off. Unlike starter-interrupt immobilizers that only block the next restart, it can shut down a running engine once the vehicle stops moving. It's there to keep a vehicle from being driven away, not to stop one on the road.
No. Horus installs alongside your ELD with no interference, and we never touch your ELD or HOS data.
About an hour per vehicle, hardwired. Do it yourself with our guide and video, hand our one-page sheet to any mechanic, or use a partner shop (Illinois today — ask about your area).
