CCTV and security tech, explained plainly.
Cameras get the glossy spec sheets, but the cable is the bit you only get one real shot at. Here's how to choose outdoor CCTV wiring that copes with UK rain, frost, UV and the dreaded dangling connector.
Doorbell cameras rarely fail because they are bad cameras. More often they are fighting for airtime on a crowded 2.4GHz band at exactly the moment everyone gets home. Here is how to tell congestion from a duff unit, and what actually fixes it.
Every November, a handful of readers email us with the same story: the cameras worked all summer, and now they vanish at teatime. It's rarely the camera. It's the power budget nobody added up. Here's how to do the maths before you buy another lens.
Spiders and moths can turn a perfectly good night view into a glowing mess. Here is why insects pick your camera, how camera-mounted IR differs from a separate illuminator, and the UK-friendly fixes that do not involve spraying the casing.
Megapixels sell cameras, but darkness exposes the truth. Here's why sensor size and light handling often matter more than a 4K badge for UK homes and shops after sunset.
Solar cameras for sheds, garages and allotments look like a neat way to dodge an electrician. Then December arrives, the panel gets four useful hours of light and the battery has to carry the rest. Here's what the numbers actually look like in a British winter.
Putting a camera on the windowsill feels like a shortcut to outdoor coverage. After dark, though, the glass often turns the footage into a white blur of reflections. Here is why it happens, what makes double glazing worse, and how UK homeowners can choose a workable fix.
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 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.
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.
