CCTV is about seeing and recording what happens around your property — whether that's checking who's at the door from your phone, keeping an eye on a driveway or side access, or simply having footage to fall back on if something happens. A well-positioned, properly installed system does far more for you than a cheap camera stuck up without much thought to angles or lighting. Every camera is properly configured for remote viewing before we leave, and all work is covered by a 12-month guarantee.

Common Problems
Signs You Might Need This Service
Blind spots around entrances
Front doors, side gates and driveways are the most common gaps in coverage that get exploited.
Poor night-time footage
Cheap or wrongly-positioned cameras often produce unusable footage after dark — proper night vision cameras and placement fix this.
No remote access set up
Many existing systems were never properly configured for phone access, meaning footage only exists locally and unreviewed.
Pricing
What Does It Cost?
CCTV costs depend on the number of cameras, resolution, cable runs and whether you need local or remote (cloud) recording. A single-camera doorway setup costs less than a multi-camera system covering a whole property. Call or WhatsApp us with your requirements and we'll give you a straightforward, itemised quote.
Every CCTV installation is covered by our 12-month guarantee, and carried out by DBS-checked, fully insured engineers.
