Ajax Alarm and CCTV Installation for a Chesterfield Home
This Chesterfield property was being renovated and needed a security system planned around both the risk and the finished look of the home. The customer wanted protection across the main house, garage and external approaches, but standard white equipment would have stood out against the darker frames and brickwork. NOX combined Ajax intruder protection with black external CCTV, a matching keypad, recording equipment and a branded warning device, then configured the system around straightforward household use.

Perimeter Alarm Protection for an Industrial Site near Dronfield
The Dronfield site contained open approaches, working areas and stored materials that could be reached before an intruder entered the main building. Internal alarm detection alone would therefore have provided warning too late in the sequence. NOX surveyed the genuine routes into the site, selected positions around the yard and covered areas, installed five Ajax outdoor detectors and an external warning siren, then tested the individual perimeter zones around the way the industrial premises operates each day.

Advice, workmanship and local support
“Brilliant service from NOX. Super professional, knowledgeable, and they went out of their way to be helpful. Everything was explained clearly and in detail. The install was tidy, and the whole process was smooth from start to finish. We were thinking about getting a security system for a while and now we're so glad we went with NOX. Would 100% recommend to anyone.”Ryan HargreavesAjax Alarm System
“Really impressed with NOX Fire & Security. Isaac, Joe and James made everything super easy from start to finish — no pressure, just honest advice and a system tailored exactly to what I needed. Love how personalised it is, and being able to control my heating, washing machine and lights all from the same security app is a game changer. The lads were friendly, tidy, and took the time to show me how everything worked before they left. Feels good knowing it's all been done properly. Would definitely recommend.”Sasha BrailsfordAjax Smart Security & Automation
“Seamless journey from start to finish! I filled in the simple form and was soon contacted by the team. They were very knowledgeable, professional and really listened to my needs. I have since had a system installed. The price was much less than I had expected and so far the aftercare has been great. I can't recommend them enough!”Jeremy BuntingSecurity System Installation
