“How much does CCTV cost?” is the first question most homeowners and business owners ask — and the honest answer is that it depends on what you are protecting, how the building is constructed, and how long you need to keep recordings. Ballpark figures help with budgeting, but a fixed quotation should always follow a site survey. Here is what shapes the price of CCTV installation across Hertfordshire.
Typical price ranges
These ranges reflect professional installation with PoE cameras, NVR, and commissioning — not consumer DIY kits from a supermarket.
Domestic homes
| Scope | Indicative range |
|---|---|
| 2–3 camera system, straightforward cabling | £800 – £1,400 |
| 4–6 camera system, standard house | £1,400 – £2,500 |
| 6–8 cameras, large property or complex routes | £2,500 – £4,000 |
| Wireless or hybrid with outbuildings | £2,000 – £4,500+ |
Homes in St Albans and Harpenden with detached garages and long driveways often sit at the upper end due to cable runs and camera count.
Commercial premises
| Scope | Indicative range |
|---|---|
| Small shop or office — 4–6 cameras | £2,000 – £3,500 |
| Trade counter or light industrial — 8–12 cameras | £3,500 – £6,000 |
| Warehouse with perimeter coverage — 12–20 cameras | £6,000 – £12,000+ |
Business CCTV adds factors like longer retention, higher mounting ( cherry pickers ), and out-of-hours working that increase labour.
These figures are indicative for 2026 market conditions. Your property may fall outside them — which is why we provide written quotations after visiting the site.
What drives the cost?
Camera count and type
Each camera adds hardware and labour. 4K turret cameras cost more than 2 MP fixed lenses but deliver better identification. PTZ cameras for large yards cost more again. We specify only what each location needs — not a round number for marketing.
Cabling complexity
Retrofit installation through occupied homes takes longer than surface trunking in a new build. Factors include:
- Loft access and insulation depth
- Brick vs timber frame construction
- Distance from NVR location to each camera
- Need for conduit on external walls
- Trenching to outbuildings or gates
A three-camera system on a modern Welwyn Garden City house may install in a day. The same camera count on a period property in Hertford with limited loft routes may take two.
Recorder and storage
NVR cost scales with channel count and hard drive capacity. Retention targets drive storage:
- 14 days — typical domestic
- 30 days — larger homes, small businesses
- 60–90 days — retail, trade, insurance-driven commercial
More retention means larger or multiple drives — budget accordingly.
Mounting height and access
Ground-floor cameras are straightforward. High-level warehouse cameras, soffit mounts on three-storey townhouses, or cherry picker work for car park poles add equipment hire and time.
Smart features and licensing
Some platforms charge per-camera licensing for advanced analytics or cloud backup. We quote ongoing costs separately so you are not surprised after installation.
Wireless bridges
Linking outbuildings adds bridge hardware and alignment time. See our wireless CCTV service for properties where trenching is impractical — common in Ware and rural Hertfordshire.
What is usually included in a professional quote
A proper quotation from Hertfordshire Security includes:
- Cameras, NVR, and storage sized to retention requirements
- PoE switch or integrated NVR ports
- Cabling, connectors, and fixings
- Installation labour and commissioning
- App setup and user training
- Basic privacy zone configuration
- Documentation for handover
Optional extras quoted separately:
- Monitor for local viewing
- Cloud backup subscriptions
- Additional hard drives for extended retention
- CCTV maintenance contracts
- Integration with intruder alarms or access control
DIY kits vs professional installation
Consumer kits from £200–£400 look attractive but often cost more long-term:
- Inadequate mounting and exposed cables fail early
- Wrong lens choice produces unusable identification footage
- Wi-Fi cameras drop offline under load
- No documentation for insurers
- No support when something stops recording
Professional installation costs more upfront because it includes survey, correct specification, concealed cabling, and accountability if the system does not perform.
Commercial cost considerations
Businesses should also factor:
- Insurance requirements — minimum camera counts or retention periods
- Downtime — installation scheduled around trading hours may need weekend rates
- Compliance — signage, data protection policies, secure export procedures
- Integration — linked office security systems with access control share infrastructure but add design time
Our dedicated CCTV installation cost page explains how we structure commercial quotations after walk-through surveys.
Hidden costs to watch for
Ask any installer:
- Is the quotation fixed, or “from” pricing?
- Are cables and fixings included?
- How many days of retention at quoted storage?
- Who owns the NVR admin password?
- What warranty applies to labour vs equipment?
- Are firmware updates included?
We provide fixed quotations after survey — no pressure to proceed.
Reducing cost without compromising security
Prioritise coverage where it matters most:
- Front door and driveway — identification and deliveries
- Rear access and patio doors — common entry points
- Side passages — often unobserved from inside
- Expand later — choose an NVR with spare channels
Installing conduit for future cameras during other building work saves significant retrofit cost.
Maintenance and total cost of ownership
Budget £150–£300 annually for domestic maintenance visits; commercial contracts scale with camera count. Maintenance catches failed cameras before you discover gaps after an incident — cheap insurance compared to the cost of missing footage.
Getting an accurate quote
The fastest path to an accurate number is a site survey. We assess:
- Property layout and vulnerable points
- Cable routes and installation time
- Retention and remote access requirements
- Privacy and compliance considerations
