Choosing the right CCTV installation company in London determines how well your property is protected and whether your footage holds up as evidence. CCTV Installation London has been designing and fitting security camera systems for commercial and residential clients across the capital since 2010. Our NSI Gold approved engineers manage every stage, from initial site survey through to camera positioning, cable installation, NVR configuration and system handover.
This page covers the types of system we install, the installation process, and what you receive at handover. For a free, no-obligation site survey, call 0800 000 0000 or use our contact form to arrange a visit at a time that suits you.
Types of CCTV System We Install
We install analogue HD, IP and hybrid CCTV systems, selecting the right technology for your budget, existing infrastructure and coverage requirements.
HD Analogue (HD-CVI and HD-TVI)
HD analogue cameras deliver 1080p or 4K resolution over existing coaxial cable. They are the most cost-effective upgrade route if your property already has analogue cabling in place. Our engineers fit HD cameras with night-vision IR LEDs that provide clear footage in complete darkness to ranges of up to 30 metres. All images are stored on a digital video recorder (DVR) with configurable retention periods. Book a free survey to discuss HD analogue options.
IP Camera Systems
IP cameras connect over a standard network, delivering four to eight megapixel resolution and supporting advanced features such as video analytics, line-crossing detection and remote access via encrypted app. They run over Cat6 cable or existing network infrastructure, powered by PoE switches, and store footage on a network video recorder (NVR).
IP systems are the preferred choice for commercial sites where high-detail coverage of wide areas, car parks or vehicle access points is required. Read our full guide to IP camera systems.
PTZ Cameras
Pan-tilt-zoom cameras can be remotely directed to follow movement across large open areas such as car parks, yards and retail floors. Modern PTZ units use AI-assisted auto-tracking, identifying and following individuals without operator input. Our engineers specify PTZ cameras where a fixed camera cannot cover a wide enough field of view from a single mounting position.
The Installation Process
Free Site Survey
Every installation begins with a thorough site survey carried out by one of our senior engineers. We walk the entire perimeter and interior of your property, identify vulnerable points, assess lighting conditions and decide on the optimal camera positions to cover all key areas without unnecessary overlap. The survey report forms the basis of your fixed-price quotation.
Camera Positioning and Cabling
Our engineers position cameras to cover entry points, access roads, loading bays, stairwells and any other areas of specific concern. We dress all cabling into conduit or surface trunking for a professional finish, minimising visual impact on your property. Where possible, we use existing cable routes to reduce installation time and disruption.
NVR/DVR Configuration and Testing
Recording equipment is configured to your specific requirements: resolution, frame rate, motion detection zones, retention period and remote access settings. We test every camera channel before we leave, confirming that day and night footage is clear, motion detection is properly zoned and remote access is working on your phone.
Handover and Training
At handover, we walk you through the system controls, show you how to review recorded footage and explain how to access the remote viewing app. We provide a full documentation pack including a site layout drawing, camera specifications, NVR settings record and user guide. Our engineers are available by phone if you have questions after we leave.
CCTV Standards and Compliance
All CCTV systems we install comply with BS EN 62676, the current British and European standard for CCTV surveillance systems. NSI Gold approval confirms that our survey, installation and commissioning procedures meet this standard and that our work is subject to independent annual audit by the National Security Inspectorate.
We also advise on GDPR and ICO compliance for systems that capture footage of public spaces, neighbouring properties or employees. Our site survey report includes recommendations on signage, data retention periods and access controls to keep your system on the right side of UK data protection law.

Frequently Asked Questions
How Many Cameras Do I Need for My London Property?
Most domestic properties in London require four to eight cameras to cover front door, rear access, side gates and driveways. A typical London office or retail unit needs eight to sixteen cameras, while larger warehouses or multi-storey premises may require twenty or more. Our site survey gives you a precise recommendation based on your specific layout.
What Resolution Should I Choose?
For most domestic and small commercial installations, 1080p (2MP) cameras deliver clear, detailed footage at a cost-effective price. For applications where you need to read vehicle number plates or identify faces at distance, we specify 4MP or 8MP cameras. Our survey assesses each camera position and recommends the appropriate resolution for that specific task.
How Long Does CCTV Installation Take in London?
A typical domestic four-camera installation takes four to six hours. A commercial system with eight cameras on a straightforward site usually takes one full day. We confirm the installation programme at the point of quotation and minimise disruption to your business or home during the work.
What Happens if a Camera Stops Working?
Cameras covered by one of our maintenance contracts receive priority response if they develop a fault. For non-contract clients, we offer reactive repair visits. In both cases, our engineers carry a stock of replacement cameras, cables and connectors so most faults can be resolved in a single visit. Find out about our maintenance contracts.
Are Your Installations Covered by a Warranty?
Yes. We provide a five-year workmanship warranty on all CCTV installations. Manufacturers also provide standard warranties on equipment, typically two to three years depending on the brand. Your installation documentation pack contains full details of all applicable warranties.
