Case studies from technical interventions across CCTV, access control, intercom, automatic door servicing, and barrier repairs in London commercial and residential environments.
One Dorma automatic swing door was not moving at all when triggered by the push button, motion sensors, or access card.
Our engineers attended site and investigated the operator control unit. They found the operator PSU had been damaged, replaced it with a new PSU, and removed the problem.
A car park barrier could not be opened from the reception computer using Paxton Net2 software.
Our engineers attended site and carried out local testing. The barrier worked locally with the remote button and card reader, but remote opening from the reception computer was not working. They checked the network containing seven Paxton Net2 controllers, found the networking fault, removed the problem, and restored full remote control from reception.
A car park barrier was not moving at all when triggered by remote, induction loop, or access card.
Our engineers attended site and carried out fault finding on the control system. They found damaged photocells, replaced them with new photocells, and removed the problem.
A Hikvision CCTV system with over 100 cameras covered a modern residential area. One day, three camera images disappeared from the monitoring screen.
Our engineers attended site and carried out fault finding on the CCTV system. They found three IP cameras had been damaged by rainwater, replaced them with new cameras, and removed the problem.
