Your ELD isn't an anti-theft device.
The ELD does its job: hours of service, compliance, a location dot. But it sits in plain sight on the diagnostic port, unplugs in seconds, and has no way to stop a vehicle from driving away. Here's the honest comparison.
| 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 |
Horus installs alongside your ELD — no interference, and we never touch your ELD or HOS data. Your compliance stack stays; the security layer gets added.
Common questions
No. Horus installs alongside your ELD with no interference, and we never touch your ELD or HOS data.
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.
