The concept behind perimeter protection is to create an alert to trespassers and would be intruders, before they have the chance to enter your building or property. Covering walk-ways or surrounding your building with an invisible fence (as shown below) will provide high intruder detection without spoiling the overall look of your property. Detectors can be installed to cover almost any area. CDS recommend the REDWALL range of products for external detection. This type of system will pick up intruders at ranges in excess of 180m. As you can see from the pictures below the units are compact whilst remaining very effective.
   With or without   integral cameras, these units will become an effective addition to your security arrangements.
