02Design
Build the right system
CCTV, intruder, fire and support options are brought into one clear proposal with the reasons behind the design.
03Deliver
Install and hand over
Equipment placement, cable routes, testing, user setup and practical handover are treated as part of the finished job.
04Continue
Maintain, monitor and expand
Servicing, monitoring, repairs and future additions remain connected through the same local point of contact.

Installed by NOX. Supported by NOX.
Installation is the start of the system lifecycle. Monitoring, maintenance, fault support and future changes can remain connected to the original design.
Monitoring
Professional oversight and agreed escalation when the property is unattended.
Maintenance
Planned inspections, testing, cleaning and system-health checks.
Priority Support
A straightforward contact route for faults, changes and future upgrades.
One Provider
Fire, CCTV, intruder and emergency-lighting support coordinated through one local point of contact.
Larger commercial projects
One coordinated strategy for fire, CCTV, intruder and continued support

Commercial CCTV · Derby, Derbyshire
Commercial CCTV Installation for a Derby Retro Gaming Arcade
Continue Arcade is not a simple open retail unit. The venue contains gaming areas, customer routes and changing activity across several parts of the premises, with bright screens and busy movement affecting the recorded scene. NOX designed an Ajax CCTV layout around those individual zones, installed the cameras and NVR, configured a usable multi-camera live view and completed the handover so the site team could review the arcade without interrupting the customer experience.

Industrial Fire & Security · Derbyshire
Industrial Fire and Intruder Installation for a Derbyshire Warehouse
The Telesis Hitachi premises required modern fire protection and intruder security that could be installed around an operational industrial environment. The two systems needed to be coordinated as one project without confusing their separate life-safety and security functions. NOX installed the Ajax EN54 Fire Hub, manual call points and warning devices alongside the commercial intruder equipment, then tested normal operation, manual activation, alarm indication and evacuation functions before completing the handover with the responsible users.

Residential CCTV & Intruder · Chesterfield, Derbyshire
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.

Designed properly. Installed properly. Supported properly.
NOX is a Chesterfield-based Fire & Security company combining local accountability with the experience and standards required for commercial, industrial and larger-scale projects. Advice, quotation, installation and ongoing support remain connected throughout.
Property before products
Entrances, routines, risks, appearance, existing equipment and future support are understood before the final device list is selected.
A quotation with reasons
Important cameras, detectors, panels and service options are explained around the job they need to do rather than hidden inside a fixed package.
Careful installation finish
Positions, cable routes, equipment colour, communication range and access for future maintenance are considered as part of the finished property.
Usable handover
Apps, playback, users, operating modes, records and practical limitations are explained clearly before the project is signed off.
Connected support after installation
Monitoring, servicing, repairs, takeovers and future upgrades stay connected to the same local business instead of disappearing into separate departments.
