From Our Website

Permanex have had a bespoke alarm panel made to our specifications that is purchased and then built by our trained engineers. The panel is designed to work alongside the NVR which has the cameras wired into. The alarm panel has zones and devices. Each zone will be associated with each camera and then up to 8 devices can be learnt onto each zone. That means one camera can have 8 wireless alarm sensors associated with it. Each sensor will constantly communicate with the alarm panel. This means that if the sensor is damaged or has a low battery or is relocated the alarm panel will issue a tamper alarm or low battery signal.


CCTV captures images in the event of a crime, providing vital evidence toward prosecuting the perpetrator. It also proves invaluable in assisting with accident investigations and assessing workforce productivity. Permanex offers the very latest in on and off-site CCTV monitoring for your construction site, void property, or temporary installation, with systems that capture detailed, crystal clear video. Our 24-hour monitoring and surveillance service protects your sites nationwide, with immediate response and swift resolution of any on-site issues.
