Security system with a long range and intelligent information system
Securing solar farms via microwave or infrared detectors systems with a very long range come into operation. The current detectors have a range of 50 to 200 m. A detection unit consists of a transmitter and a receiver that are installed opposite of each other. In between there is an electro-magnetic field which triggers an alarm when it identifies a changing object or a person moving. Volume and movement speed of the object are being analysed in order to filter and interpret the perturbation of the field.
The corner arrangements are overlapping as the detectors can only build up full power after a few metres and the ellipsoidal fields near the transmitter and receiver have a small diameter. This prevents crawling under.
Microwave barriers are proven and versatile applicable technologies to secure long straight distances preventatively. Outside influences have to be considered during concept phase as fog, heavy rain and terrain conditions can affect the functionality. Using high quality components provide a trouble-free surveillance with a small amount of unwanted alarms.
With microwaves it should be noted however that because of the shaping of the electromagnetic field, a space of up to 5 – 6 m between the fence and the first row of panels is required, especially for long tracks.
