If you’re building your secret, evil lair that has lots of detection mechanisms for those super heroes who want to break in and put an end to your villainous career, then you’re going to need some of these driveway probes that sends an alert when a car enters your property. The probe is buried in your driveway, and a line is run to the weatherproof transmitter that runs off of a 9V battery. The transmitter sends the signal to the receiver up to 3000 feet away in your house.
- Buried driveway probe won’t send false alarms to transmitter
- Transmitter sends radio signal to receiver up to 3000 feet away
- Four different tones alert to breaches from up to four different transmitters
