Continue Arcade in Derby protected by a professional CCTV system installed by NOX
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.

Telesis industrial premises with Fire and intruder systems installed by NOX
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.

Chesterfield home protected by a NOX Ajax intruder alarm and black CCTV cameras
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.

Why NOX

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.

01

Property before products

Entrances, routines, risks, appearance, existing equipment and future support are understood before the final device list is selected.

02

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.

03

Careful installation finish

Positions, cable routes, equipment colour, communication range and access for future maintenance are considered as part of the finished property.

04

Usable handover

Apps, playback, users, operating modes, records and practical limitations are explained clearly before the project is signed off.

05

Connected support after installation

Monitoring, servicing, repairs, takeovers and future upgrades stay connected to the same local business instead of disappearing into separate departments.

06

Real evidence, not stock claims

Genuine project photography, detailed case studies and verified customer reviews show the type of work NOX has actually delivered.

★★★★★
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
★★★★★
We had NOX Fire & Security install our commercial fire alarm system alongside an intruder alarm, and the whole experience was spot on from start to finish. Clean, professional installation, everything clearly explained, and the system is easy to manage through the app with instant alerts. The fire system is clear, reliable and easy for the team to manage without overcomplicating things. No pushy sales, no unnecessary contracts — just honest advice and proper workmanship. You can tell they care about doing things right. Highly recommend NOX for any business looking for fire or security systems in Chesterfield / Sheffield.
