Introducing the Paradox NV780MR, this device allows your to cover a direct line of sight up to a total of 24 metres on your property, this is from achieved by 2 x 12 metre infrared beams from either side of the device. The device sends two beam left and two beams right and requires both beam on any given side to activate to generate an alarm state, this means less false alarms and your pets up to 40 kilograms will not activate the device either. With both hard wired and wireless models it gives us great installation flexibility on even the toughest two storey installations. If your thinking of installing a perimeter alarm at your premise or simply want to protect the front of your house at night, contact us for more information.
