Home security designed around the property
NOX designs professionally installed CCTV, Ajax alarms, perimeter protection and smart security for family homes, larger properties, rural sites, driveways, garages and outbuildings across Chesterfield, Sheffield, Derbyshire and South Yorkshire. The property, routine and level of protection decide the system rather than a fixed package.

Choose the requirement first, then the technology
Intruder alarms, CCTV, perimeter detection and smart cameras solve different parts of the property. NOX can design one system or combine several without unnecessary duplication.

Home CCTV
Recorder-based CCTV for driveways, entrances, gardens, vehicles, garages and outbuildings with remote viewing and playback.

Explore Support for an Existing Home System →From a normal family home to a property with several external areas
The same property-led approach works for a normal family home, a renovation, a larger house or a site with several external areas. The specification reflects the building and how it is used.
Family homes
Protection planned around pets, children, bedrooms, extensions, night mode and everyday entry routes.
Driveways and vehicles
CCTV and suitable detection for approaches, parking areas, gates and vulnerable side access.
Garages and outbuildings
Detached spaces assessed for distance, construction, power, network and system communication.
Larger and rural properties
Longer boundaries, several buildings and higher camera counts planned as one project or delivered in phases.
Takeovers, faults and sensible upgrades
NOX can assess suitable wired, wireless, hybrid and CCTV systems installed by another company. The inspection identifies access, condition, compatibility and whether service, repair, selective upgrade or replacement is the sensible next step.

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.

Solar and floodlight smart-home CCTV
The customer wanted external visibility around the home without the cabling and recorder arrangement of a conventional multi-camera CCTV system. The property was therefore better suited to a carefully planned smart-camera route rather than a generic wired package. NOX selected Eufy solar and floodlight options for the relevant areas, checked the intended views, wireless connection and charging conditions, configured the app and detection settings, and demonstrated how the homeowner could use live view and alerts after installation.

Residential CCTV and intruder protection
This Sheffield home required CCTV and intruder protection to work together around the front approach, driveway and main access points. NOX installed external cameras alongside an Ajax alarm system, using a visible external siren, door protection and a centrally connected hub for straightforward everyday control.
Questions to answer before choosing a system
Clear advice, tidy work and a proper handover
“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
