CCTV and security tech, explained plainly.
A clear picture of a face is only half the story. If the clock on your CCTV is out by minutes, hours or a day, an otherwise useful clip can become awkward to use in an insurance claim or a police request. Here is how clock drift happens and how to keep a mixed system honest.
The UK's minimum-security rules for connected devices have been in force since April 2024, but plenty of CCTV kits are still commissioned as if default logins were fine. This is a practical look at what the rules actually require, where installed systems fall short, and the fixes that take an afternoon rather than a redesign.
Most UK cameras ship with sound capture switched on, and hardly anyone thinks about it again. Audio is a separate question from pictures — and a shared driveway or shop counter is where it gets awkward.
Nearly every UK system is set to keep a month of footage, and almost nobody can say why. Here's the storage arithmetic behind retention, what the ICO does and doesn't require, and how to write a rule you could actually defend.
Most UK camera systems go up in an afternoon and get forgotten for years — until someone asks for the footage. Here's the plain-English version of the notice, the retention policy and the subject-access basics that should sit alongside any home or small-business CCTV setup.
Most small-shop CCTV is installed by whoever had a ladder and a free Saturday. The result is four cameras pointed at nothing useful and a very well-documented kettle. Here's a layout that gets evidence you can actually use — without turning the staff room into a surveillance zone.
Four thousand pixels across sounds like plenty until you work out how few of them land on a number plate fifteen metres away. Here's the arithmetic that actually predicts whether your camera can read a registration — plus three tests you can run in your own driveway before you spend a penny.
Half the alerts on your phone are foxes, posties, drizzle and a wheelie bin catching the light. The other half might be genuinely useful — if you know what the camera is really doing when it says 'person detected'. Here's how to tell smart analytics from expensive noise.
A camera bought to watch a van ends up watching next door's patio, and suddenly the street WhatsApp group is involved. Here's what the law and the ICO actually say, where the genuine risk sits, and the cheap fixes that cost nothing but a ladder and twenty minutes.
From now until Christmas, more parcels will go missing than at any other point in the year — and most doorbell footage of the moment is unusable. Here's how to frame a doorstep so the faces, timings and evidence actually hold up.
You can add a camera to a rented flat without turning the walls into a colander, but no-drill kit still comes with tenancy, privacy and neighbour considerations. Here is the practical route through permission, mounting, window cameras and getting your deposit back.
A knock at the door and a request for your camera footage can feel straightforward, but handing over the whole recording is rarely the best move. Here is a calm, plain-English approach to police requests, insurance claims and neighbour disputes.
A £30 doorbell camera looks like a bargain until you add up five years of cloud subscriptions, battery packs and a replacement unit. Here's the honest maths — plus what UK GDPR actually asks of householders filming shared paths.
Sunset in Manchester is around 4.30pm on 7 November, and it gets worse from here. Here's why home cameras fall apart in the wet, dim, low-sun months — and the settings changes that actually fix it, without buying anything new.
