Review on π Dahszhi Dual Laser Detector Alarm Beam Sensor: Indoor 300m & Outdoor 60m Infrared Detection for Optimum Security by Mahmut Ojeda
Haven't installed it yet
looks like the DS Electric Eye detection system I've installed for years. When setting up the electric eye, bring a flashlight and chair with you to calibrate it. You don't need a second person if you place a chair directly in front of your eyes and have a lantern on the chair facing the other end.
- Application: Ideal for installing in a security system in a school, office building, hospital, home yard, etc.
- Protection
