My new wonderful neighbors are crackheads who can't keep from stealing from people. I currently have an alarm system with motion sensors on the interior and motion sensors and a driveway sensor on the exterior. I also have cameras. The problem is that the exterior motion sensors are not always accurate and neither are the cameras (light changes and bugs). I was looking at automatedoutlet and say the aleph ALL-MY-100 IR beams with 400 ft range and was wondering if anyone has used them. I don't want another device that will give me lots of false positives. I need to know which direction to shoot (which direction my neighbors have entered the property and in Florida we can shoot first ask questions later). I would plan on using multiple sensors (3 acres) to cover all entry points to the property. anyways... anybody ever used on of these IR Beam Sensors.
