CCTV and security tech, explained plainly.
A high camera above the front door feels safe and tidy, but it often gives you a lovely view of hoods, caps and the top of a van. This guide explains the practical height and angle that actually help you answer the only question that matters after an incident: who was that?
The hard drive inside your NVR or DVR is the part most likely to let you down first. Here is how to read the warning signs, run a sensible SMART check, and swap the drive before it takes your footage with it.
Remote viewing usually fails because your home broadband struggles to send video out, not because the camera has given up. Here is why live view stutters, why playback can still work, and how to tune bitrate and substreams without turning your recordings into mush.
A power cut is rarely the end of a CCTV system. The tricky part is what happens when the power returns: a recorder with the wrong clock, cameras stuck offline and remote access that quietly died with the router. Here is a practical UK plan for UPS sizing, surge protection and a simple quarterly test.
The hard drive inside your recorder is the one component in your CCTV setup that fails without making a fuss. No alarm, no flashing light, just fewer recordings than you thought you had. Here is why that happens, and a realistic five-minute check that keeps you ahead of it.
That IP65 badge on the box is a lab test with a nozzle, not a promise about sideways rain, salty air or condensation. Here's what the two digits actually cover, where water really gets in, and the checks worth making before you trust the word 'weatherproof' on a British exterior wall.
Fairy lights, foil garlands and an inflatable Santa can turn a perfectly good CCTV view into a mess of glare, ghosting and constant alerts. Here’s a plain-English guide to why festive decorations upset home and shop cameras — and a simple pre-December checklist to fix it before the dark nights really set in.
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.
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.
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.
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.
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.
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.
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 £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.
