Electro Guard Watch

"Anybody" approaching your house on foot or in a vehicle will be detected by the PIR sensor of and it sends a wireless signal to the receiver indoors, which chimes an alert. The device is wireless and has a range of ca. 50m (line of sight) It can work well if installed correctly at a suitable place. We offer a 3 month warranty for this item.

Please note: This is a basic entry level alarm system based on a PIR sensor. This model is often sold as “weather proofed”. We can not fully agree to that and strongly recommend installing the PIR sensor in a sheltered place to avoid water damage. The Sensor of this Driveway alarm system is based on PIR technology. A passive infrared sensor (PIR sensor) is a sensor that measures infrared (IR) heat radiating from objects in its field of view (ca. 8-12m). It happens that PIR sensors are triggered by wind, sun, birds etc. It can also happen that the sensor is missing a passing car now and then. This is not a problem of this particular PIR sensor but a systemic problem of all PIR sensors in an outdoor application. PIR sensors are relatively cheap and very reliable (indoors) but outdoors they are not 100% reliable. This can be minimized if installed correctly but it will never reach the 99.5% reliability of an IR beam sensor or a magnet field sensor (see our other driveway alarms).
