Here’s another key outdoor automation component, the Cartell CP-2 Self Contained Driveway Sensor Probe. This is pretty self explanatory, your bury it about 6″ away from your driveway, 18″ deep and it senses when a car, motorcycle or other vehicle comes onto your driveway. This is a nice feature to automatically turn lights on, switch/record a video source (camera) or do something when a car approaches your driveway. The CP-2 is self contained and comes with a 4-conductor cable in lengths from 100-500′. You can even power it from your HAI OmniPro II since it takes low power 12v (via two conductors) and the other two conductors go to a zone. The CP-2 starts at about $200 for a 100′ version and goes up.
