A problem with unwanted visitors has been overcome for this farmer based in Lincolnshire by installing an external beam system, a master blaster and a locally monitored CCTV system. 

If an intruder enters the site the external infrared beams will detect movement and switch on the security lighting around the farmyard and activate the master blaster sirens. This then triggers the CCTV system, linked to a screen in the nearby farmhouse, providing enhanced security.
