Case Studies

A few months into the project an intruder made his way onto site. The system picked up the intruder, our security manager and the Police were notified who quickly apprehended him. I was able to use the monitoring station to export the footage which was then sent to our client for further investigation.

Galliford Try PLC

A group lads wandering around a vacant property were so shocked by the P.A warning from the SiteDefender monitoring agent that if it wasn’t for the fact that their faces were caught so clearly on the way in, the blur as they ran off would have made recognising them nearly impossible.

Bit of a blur

A vacant property in Kettering was regularly broken into by a group of teenagers. The developers began work, SiteDefender was installed and by the weekend following the installation the police had the teens in custody and some nice supporting CCTV footage.

Perfect Timing

After a late night a worker decided that the site would be a good place to sleep it off; he climbed up and over hoarding and through the rafters of the site cabin, unfortunately for him SiteDefender had caught him as soon as his head crossed the barricade.
