Our driveway is 300 feet long and the only way onto our property. I have a large workshop at the end of the driveway and separate from the house. I wanted several things. I wanted a visual way to warn "visitors" that they had been detected entering my property, and I wanted an audible alert to warn us that someone had entered the property. For that to happen, I needed a battery powered sensor that could easily transmit a signal 300 feet from the entrance to our driveway through a wall to a receiver in my workshop/house. Because I only wanted this to happen after dark, I needed a sensor that would only detect motion between sunset and sunrise. Furthermore, because my workshop is small compared to my house, I wanted to be able to turn the alert volume down to minimum in the workshop, yet maximum volume in the house to wake us in the middle of the night. I attached a 12 volt SECO-LARM SL-126Q/B Blue Security Strobe Light to the receiver in the workshop. The Guardline receiver allows me the option of powering the strobe light for up to 60 seconds! Imagine an intruder walking or driving into our driveway at night only to be greeted by a blue flashing light at the end of a dark driveway! Of course, I also wanted a battery back-up. There would be no alerts in the event of a power failure. With one Guardline wireless sensor, two Guardline receivers (with battery back-up), and one 12 volt SECO-LARM SL-126Q/B Blue Security Strobe Light, I was able to make all of this happen. I applied a generous coating of Magic Lube silicone grease to the seams of the sensor and strobe light to prevent water damage. It works every time and we've never had a false alarm.
