The GL2000 model has a 500 ft (150 m) range and the GL5000 model has a 1/4-mile (400 m) range. The system runs on a radio frequency, and uses PIR technology to detect unwanted visitors. When triggered, the sensor will send a signal to the receiver which will play a melody.
Both models are great for multiple applications, including:
• Alerting you when visitors enter your driveway
• Deterring trespassers and thieves from entering your property or building
• Alerting you to wildlife on your land
• Using in drive-thrus to signal that a customer has pulled in, and more!
