Review on 🔒 Dahszhi Dual Laser Detector Alarm Beam Sensor: Indoor 300m & Outdoor 60m Infrared Detection for Optimum Security by Ryan Dot

Two of them have been working on our territory for more than a year. They are outdoors in the rain and hot weather. You need to know what you're doing to set up a true perimeter system. This product gives you the ability to have a folding system simply by adding a ground release. I asked the local sheriff's department to confirm how well built it was. I've used many other $200-$800 systems that have failed. I built them as a standalone perimeter system with a rear battery for less than $180, including 500 feet of underground cable. never have problems
