Ajax alarm installation, configuration and aftercare in Chesterfield
Ajax is NOX's preferred residential intruder platform because it supports flexible detection, visual verification, simple user control and future expansion. The equipment is selected around the property rather than sold as a standard kit.

The Ajax platform is strongest when it is designed and configured properly
Hub choice, device placement, user permissions, night mode, photo verification, sirens and communication paths should be planned as one system and tested before handover.

Ajax intruder and black CCTV for a Chesterfield home
The property was being renovated and needed a modern security system that would remain discreet against the finished brickwork. NOX combined app-controlled intruder protection with black external CCTV cameras, a keypad and a branded external warning device.

External Ajax detection at a Dronfield industrial site
The Dronfield site needed protection around its external approaches rather than relying only on detection inside the building. NOX designed a perimeter layer using five outdoor Ajax detectors and external sirens around the key routes into the premises.

Residential CCTV and intruder protection
A Sheffield home received both CCTV and intruder protection, planned as one residential project and configured for straightforward everyday control.

“We recently had NOX install cameras, smoke screens, and alarms at our office and the whole experience has been spot on from start to finish. From the very first phone call with Isaac, everything felt straightforward and reassuring. He took the time to explain our options, answered all our questions, and helped design a system that made sense for our building and our budget. No pushy sales tactics at all, which was refreshing. The installation was smooth, the team were professional, and even after everything was fitted, Isaac has been on hand to help with any follow-up questions. A really great service and a company I'd happily recommend.”Nathan De La RosaCommercial CCTV, Alarms & Smoke Screens
