508D Double-Guard Proximity Sensor

Dual zone motion detector for Python security systems

The 508D Double-Guard proximity sensor triggers your alarm when a high-density object, like a hand or a tool, enters the cabin of your vehicle. You can set this sensitive dual-zone sensor to trigger a chirp when someone enters a warning zone just outside your vehicle, then to trigger a full alarm response when the second inner zone is violated. You'll enjoy an extra measure of protection when your alarm is armed.
