A coordinated response
Light and speech work together to make the system’s response clear to the person at the vehicle.
PerimeterEye Vehicle Theft DeterrenceEvery way to steal a car
Every way to steal a car
starts with someone at your car.
Immobilizers, trackers, and steering locks protect the car’s own systems. A tow truck, a relay device, or a stolen key goes around them. None of those work without a person on your driveway, at your car, and that is where PerimeterEye responds, in seconds: a tracking searchlight finds them, a live AI voice addresses them, and a 130 dB siren escalates, while you watch live.
Real system response / Staged vehicle break-inYouTube
A staged vehicle break-in on a real property. Voice warning, tracking searchlight and a 130 dB siren — automatic, on-site, no operator. The scenario was staged for filming; the system's responses were not.
Play with sound to hear the voice warning and siren.Frame by frame, from the film
Five seconds from the door handle to running away.
Stills from the film with its on-screen analysis and phone alert, on the Front Door 2 camera’s own clock. The door handle registers at 21:04:26. By 21:04:29 all systems are activated, and at 21:04:31 the person is running.

The first alert
The person in the black hoodie is at the car, and the first alert already describes them: at the vehicle in the driveway, and has not approached the house.
2 of 6 · 21:04:26View full size
Contact with the door handle
The person reaches for the driver’s door. The analysis builds second by second: a person, no match to anyone it knows, loitering at the vehicle, and now contact with the door handle.

Car theft in progress
Three seconds after the door handle, the analysis is complete: the activity doesn’t match the household’s patterns and matches vehicle theft. All systems activate.

The searchlight lands
The searchlight hits the person at the driver’s door. The alert reads: spotlight, voice warning and siren activated, with a tap to cancel the escalation.

Running from the car, still lit
Five seconds after touching the door handle, the person is running from the car, and the searchlight stays on them.

Followed away from the car
The searchlight follows the person past the tree and along the drive. The car hasn’t moved.
Filmed September 15, 2026, on a real property. The break-in was staged for filming; the system’s response was automatic, with no operator. Play the film above with sound to hear the voice warning and the siren.
The tow-truck problem
In-car anti-theft assumes someone will try to drive the car.
Immobilizers, kill switches, and keyless settings share one idea: stop the car from being started or driven. The common ways cars are taken don’t need either.
- A tow truck or flatbed
- The car is lifted or winched, never started. The immobilizer, the kill switch, and the steering-wheel lock all leave with it.
- A relay device
- Keyless cars unlock and start when the key is close. A relay device carries the key’s signal from inside the house out to the car, so the car treats the thief like the owner.
- A stolen or copied key
- With a working key, the car’s own protections step aside, exactly as they were designed to.
- A GPS tracker
- Useful for finding the car afterward. Nothing happens while the car is being taken, and a tracker can be found and removed.
- A car alarm
- A door sensor, or on some cars a tilt sensor, sets off the horn. It is a noise from a car in the dark, and it tells nobody who is there.
Every one of these needs a person standing at your car.
A tow operator has to walk up to the car to hook it. A relay thief stands at your door, then at the car. Someone with a key still has to open it and drive it off your driveway. At a property covered by PerimeterEye, that person is found by a tracking searchlight, addressed by a live AI voice that speaks to what they are doing, and put under a 130 dB siren, while your phone shows you the live view. In the film, it took five seconds from the door handle to the person running.
What separates PerimeterEye
During the theft, or after it?
Most of these are worth having. Only one of them responds to the person at the car while it is happening.
| Option | While the car is being taken | Once it’s gone |
|---|---|---|
| Immobilizer or kill switch | Blocks the engine from starting. A tow truck never needs to start it, and a relay device or a stolen key gets past a factory immobilizer. | Nothing. |
| Steering-wheel or pedal lock | Makes driving it away slow and obvious, but rides along when the car is lifted onto a truck. | Nothing. |
| GPS tracker or tag | Nothing happens at the car. | Helps locate the car, unless the tracker was found and removed. |
| Car alarm | Sounds the horn when a door, or on some cars a tilt sensor, is triggered. Nobody is told who is there. | Nothing. |
| Cameras and floodlights | Record it and send a motion alert. A fixed light may switch on, but it doesn’t follow anyone. | A recording of the theft. |
| PerimeterEye | Finds the person at your car with a tracking searchlight, speaks to them, and escalates to a 130 dB siren within seconds, while you watch live and can talk to them yourself. | The Event Timeline keeps the whole event: the camera views, the analysis, and every response. |
The hardware behind the response
The Brain directs the searchlight at the activity.
A motorized searchlight is one connected part of the system. The Brain commands where it aims and what it follows, using the camera context, system assessment, and your settings.
Volume you control
The dedicated siren has adjustable volume and owner activation and stop controls.
The product photo shows the black and white searchlight finishes. Each unit has 355° rotation and 90° tilt; useful coverage depends on mounting, sight lines, and the property.

Coverage around the vehicle
Plan for where a person can approach.
A clear view of the vehicle is useful. A clear view of the activity around it is essential.
- Driver and passenger sides
- Check whether each side remains visible when another vehicle is parked nearby. Door-handle activity can be hidden by the vehicle body or the next parking space.
- Where a truck would line up
- A tow truck has to back up to the car or stop at the end of the drive. Include the apron and the approach in a camera view, not only the car.
- Front, rear, and walkways
- Include the paths people use to reach the car and the space around it. Trees, walls, and garage corners can interrupt a view.
- Open and detached parking
- Consider the approach to a detached garage, carport, trailer space, or outdoor collection, including suitable power and connectivity for the equipment.
- The parked arrangement
- Plan around how vehicles are actually stored. A camera angle that works for one low car may be obscured when a truck occupies the next space.

Vehicle Theft Deterrence questions
Can PerimeterEye stop a tow truck from taking my car?
It’s built to interrupt a tow-truck theft while it’s happening, not to record it for later. To hook up a car, someone has to walk up to it, and at a driveway PerimeterEye covers, they do it in a tracking searchlight, addressed by a live AI voice and put under a 130 dB siren, while you watch live and can speak to them yourself. Its tools are light, voice, sound, and alerts, and no security system can guarantee prevention of every incident.
My car already has an immobilizer and a tracker. Why add this?
Those protect the car’s own systems and help recover it afterward. They don’t react to a tow truck, and a relay device or a stolen key gets past a factory immobilizer. PerimeterEye covers the place the car is parked, so it responds to the person at the car whatever method they use.
How fast does it respond?
In the filmed vehicle break-in, the analysis registered contact with the driver’s door handle at 21:04:26 on the camera’s clock, all systems activated at 21:04:29, and the person was running from the car at 21:04:31: five seconds from the door handle.
Is the vehicle demonstration a real theft?
The attempted break-in was staged on a real property for filming. The working PerimeterEye system responded automatically with a targeted voice warning, tracking searchlight, and siren; an operator was not driving the response.
Does this require a device installed inside my car?
No. PerimeterEye responds around parked vehicles from the property: cameras and connected deterrence hardware cover the parking area. Nothing is installed in each vehicle, so it covers any car parked there, including a guest’s.
What happens when I walk out to my own car?
PerimeterEye learns your property and your household and assesses ordinary activity in context, so walking to your own car is not treated as a theft. There is nothing to arm or disarm. The deterrent response is for activity it assesses as concerning, and you can change or stop it from your phone or wall panel.
Can it cover several vehicles or a detached garage?
Yes. Coverage can be planned around multiple parking spaces, a detached garage, a carport, or a long drive. Camera angles need to account for the vehicles themselves blocking views, including taller vehicles or a changed parking arrangement.
What does vehicle coverage cost?
Essential covers a driveway and the approaches to the house, as low as $145.17/mo for Essential (36 monthly payments at 10% APR, $0 down, through Affirm or Klarna, subject to approval). The software and AI service is included for the first 6 months, then $99/month. Detached garages, several vehicles, and long drives usually suit Advanced or Estate, and a specialist can size it with you.
