Service & Monitoring
Monitoring, planned maintenance and support for installed systems
Start with the outcome you need. NOX will review the property, equipment, access, condition and required response, then confirm whether the next step is monitoring, a planned service visit, takeover assessment, repair or upgrade across Chesterfield, Sheffield, Derbyshire, Derby and the Peak District.

Explore support →Servicing & Maintenance
Choose the system that needs planned support
Each system keeps its own testing scope and records. Customers managing several systems can still coordinate suitable visits, renewals and reporting where practical.
Intruder Alarm Servicing
Devices, batteries, sirens, communication, user settings, event history and service records.
View service →CCTV Maintenance
Camera cleaning, image quality, recording, storage, playback, remote access and upgrade recommendations.
View service →Fire Alarm Servicing
Planned commercial testing, records, defect reporting, takeover inspections and remedial quotations.
View service →Emergency Lighting Servicing
Functional checks, annual duration testing, failed-fitting reports, records and coordinated remedials.
View service →System takeovers
Assess what can be retained before recommending replacement
A takeover starts with system access, ownership, documentation, faults, age, supportability and the outcome the customer needs. Useful equipment can be retained where practical, with repairs or selective upgrades separated clearly from routine servicing.
Monitoring
Defined signal handling when the premises is unattended
Suitable intruder alarms and commercial fire systems can connect to professional monitoring with agreed contacts and escalation. Compatibility, signalling, system condition and planned maintenance are confirmed before activation.
Ongoing Support Packages
A natural route for customers who want suitable systems looked after properly
Eligible alarm monitoring, intruder servicing, CCTV maintenance, planned visits and selected fire services can be coordinated under one support arrangement. The written proposal confirms what is included, what remains separate and how renewals are managed.
Planned visits
Service frequencies and access are arranged around the property, systems and operating requirements.
Consolidated dates
Suitable visits and renewals can be aligned where practical without mixing the technical service records.
One point of contact
Questions, faults, quotations and future upgrades remain easier to coordinate across the agreed systems.
Clear scope
Included systems, exclusions, parts, repairs and response routes are confirmed before the agreement begins.
Before ongoing support
Condition, access and responsibilities are made clear first
System make and age
Panels, devices, cameras, recorders, communication routes and parts support need to be understood.
Access and ownership
Engineer codes, app accounts, recorder passwords and available documentation affect the takeover route.
Faults and remedials
Known issues, disabled devices, storage faults and battery condition are separated from routine service work.
Written agreement
Included visits, exclusions, parts, response route and renewal terms are confirmed before ongoing support starts.

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.

Commercial CCTV · Retford, DN22
Ten-camera Hikvision CCTV system at a former bank
The former bank is a substantial multi-room commercial property where a small number of general camera views would not have provided useful coverage. Entrances, corridors, individual rooms and the external approach all needed to be considered separately. NOX designed and installed a ten-camera Hikvision system, introduced a new recorder and dedicated display, checked the live and recorded images across the building and completed a handover suited to the day-to-day management of the Retford premises.

Estate CCTV · Chatsworth Estate, Derbyshire
Rural estate CCTV upgrade with Ajax 8MP and AI detection
This project involved upgrading an older CCTV arrangement at Chatsworth Estate and replacing it with a more modern security setup better suited to a large rural property. The site included substantial stone buildings, open ground, yard areas, long external views and the sort of changing daily activity common at estates, farms and larger country homes. NOX planned the upgrade around the estate layout so the finished system would not only improve image quality, but also provide more practical coverage, clearer live viewing and a stronger overall CCTV platform for ongoing rural security.

Local support backed by real installation experience
“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
“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.”Rory StirlandCommercial Fire Alarm & Intruder Alarm
