CCTV Systems for Commercial Premises
A CCTV system that nobody watches, nobody maintains and nobody reviews is not security - it is a false sense of security. The value of commercial CCTV is not in the cameras. It is in what the cameras are connected to, who is reviewing the footage, how it integrates with your other security and fire systems, and whether it is actually recording when an incident occurs.
Electrifire designs, installs and maintains CCTV systems for commercial premises across London, Kent and the M25 corridor. We design CCTV as part of the wider fire and security system rather than as a standalone product - integrating it with access control for visual verification of access events, with intruder alarms for alarm activation verification, and with vehicle barriers for ANPR-based vehicle recognition. Where out-of-hours monitoring is required, we can connect the system to an NSI-approved alarm receiving centre for professional remote monitoring.

CCTV Design and Installation
A commercial CCTV system starts with understanding what you need to see, when, and why. The site survey identifies the areas that require coverage, the lighting conditions, the camera positions, the recording requirements, and any integration points with other building systems. The design is then specified to meet the operational requirement - not to sell as many cameras as possible, but to provide effective coverage of the areas that matter.
- IP network cameras - high-resolution digital cameras connected via your data network, supporting remote viewing from any device with an internet connection
- HD analogue cameras - cost-effective option for simpler installations where network infrastructure is limited
- PTZ cameras (pan, tilt, zoom) - for large open areas, car parks and perimeters where active tracking or operator-controlled viewing is required
- Fixed cameras - for targeted coverage of specific entry points, corridors, stairwells and high-value areas
- Thermal cameras - for perimeter detection in low-light or no-light conditions
All cameras are selected for the specific application - indoor or outdoor, lighting conditions, field of view, resolution required for identification versus detection, and weatherproofing rating. We do not specify domestic-grade equipment for commercial applications.
Commercial CCTV systems typically use network video recorders (NVR) for IP systems or digital video recorders (DVR) for analogue systems. Storage capacity is specified based on the number of cameras, resolution, frame rate and the required retention period. For most commercial premises, a minimum of 31 days continuous recording is recommended, though specific retention periods should be justified under data protection law and documented in your CCTV policy.
Modern IP CCTV systems support remote viewing from smartphones, tablets and desktop computers. This allows site managers and security personnel to view live footage, review recorded events and receive push notifications from anywhere with an internet connection. Remote access must be secured with strong authentication and encrypted connections to prevent unauthorised access to your video feeds.
CCTV captures personal data, which means it falls under the UK GDPR and the Data Protection Act 2018. As the operator of a CCTV system, you have legal obligations including carrying out a data protection impact assessment before installation, displaying clear signage informing people they are being recorded, documenting a retention policy that justifies how long footage is kept, restricting access to footage to authorised personnel, and responding to subject access requests within the statutory timeframe. The Surveillance Camera Code of Practice provides 12 guiding principles for responsible operation. Electrifire can advise on the practical data protection considerations during system design, but you should also consult the ICO guidance for your specific obligations.
CCTV Remote Monitoring
A CCTV system that records footage is useful after an incident. A CCTV system that is actively monitored can prevent the incident from escalating or enable a faster response while it is happening.
Remote CCTV monitoring connects your camera system to a professional alarm receiving centre (ARC) where trained operators review footage in response to triggered alerts. When the system detects an event - whether from motion detection, analytics triggers, intruder alarm activation, or access control alerts - the monitoring operator evaluates the footage and initiates the appropriate response. That response could range from an audio challenge through on-site speakers to dispatching a keyholder or contacting the police.
- Detector-activated alerts trigger the ARC operator to review live and recorded footage from the relevant cameras
- The operator evaluates the situation and determines whether it is a genuine security event or a false alarm
- For confirmed events, the operator initiates the agreed response - audio warning, keyholder dispatch, police contact
- Every event is logged with timestamps, operator actions and footage references
- Monthly or quarterly reports summarise all activations, responses and trends for your review
Remote monitoring is particularly valuable for premises that are unoccupied out of hours - warehouses, offices, commercial estates and multi-site portfolios where employing on-site security guards across every location is not cost-effective. For premises managed in accordance with SFG20, CCTV monitoring aligns with the security system tasks specified in that framework.
When CCTV monitoring is integrated with the intruder alarm system, alarm activations automatically trigger the monitoring operator to view the relevant cameras. This provides visual verification of the alarm event, which is increasingly required by police forces as a condition of response. Without visual verification, many police forces will not attend a standard intruder alarm activation. See our intruder alarms page.
Some insurance policies require CCTV monitoring as a condition of cover, particularly for higher-value commercial premises, warehouses and premises with a history of security incidents. The monitoring must typically be provided by an NSI or SSAIB-approved alarm receiving centre, and the system must be installed and maintained to the relevant standards. Electrifire can advise on whether your insurance requirements include a monitoring obligation.
CCTV Maintenance and Support
A CCTV system that is not maintained will fail at the worst possible time. Cameras collect dust, condensation and cobwebs. Lenses lose focus. Connections corrode. Hard drives fill up or fail silently. If nobody is checking, you will not know the system has stopped recording until you need the footage and it is not there.
Electrifire provides planned maintenance for CCTV systems as part of a wider security and fire maintenance contract. A typical service visit includes cleaning and inspection of all cameras and housings, verification that every camera is recording correctly, playback testing of recorded footage, hard drive and storage health checks, network connectivity and cybersecurity verification, review of remote access credentials, and functional testing of any analytics or detection features. Any faults are reported immediately with a clear recommendation.
For FM and property management companies, CCTV maintenance can be coordinated across your portfolio as part of a wider planned maintenance contract. We schedule CCTV servicing alongside fire alarm and access control maintenance visits, so that the integration between systems is verified at the same time. See our planned maintenance page.
If you have an existing CCTV system installed by another company, we can inspect it, assess its condition, check whether it is actually recording, and bring it into a planned maintenance schedule. Where the system is outdated - analogue cameras with poor resolution, unsupported recording equipment, or systems with known cybersecurity vulnerabilities - we can advise on a phased upgrade path.
