Video Doorbell Basics: What You Need to Know

Thinking about adding a video doorbell? You’re not alone – UK homeowners are swapping old buzzers for smart cameras that let you see who’s at the door from your phone. The idea is simple: a camera, a microphone, and a speaker tucked into a weather‑proof housing, all hooked up to your Wi‑Fi. But before you click ‘buy’, there are a few practical things to sort out.

Wired vs Battery: Which Is Right for You?

Most people ask, “Do I need to run wires?” The answer depends on your home’s existing wiring and how hands‑on you want to be. A wired doorbell pulls power from the transformer that already runs your traditional buzzer – usually a 16‑volt AC unit in the UK. If that transformer is in good shape, a wired model gives you unlimited power, so you never worry about a dead battery.

Battery‑powered units are attractive because they’re quick to install – just snap the mount onto the wall, pair with the app, and you’re set. Modern batteries last 6‑12 months, especially if you tweak settings like motion‑triggered recording. Keep a spare on hand, though; a dead battery means you miss visitors.

Hybrid models exist too: they run on battery but can be plugged into the existing transformer for trickle‑charge. This gives you the best of both worlds – no digging for wires, and the battery never runs out.

Top Features to Look for in 2025

HD video and night vision. You want a clear picture day or night. Look for at least 1080p resolution and infrared LEDs for dark‑side clarity.

Two‑way audio. A built‑in speaker and mic let you talk to delivery drivers or chat with guests without opening the door.

Motion zones and smart alerts. Good systems let you draw zones in the app so you only get alerts when someone’s really at the door, not every passing car.

Chime compatibility. In the UK, many homes still have a traditional mechanical chime. Check that the doorbell can work with a standard 16‑V transformer and will still ring your indoor chime.

Local storage or cloud subscription. Some brands offer a microSD slot for on‑device recording, which avoids monthly fees. Others give you cloud storage but charge a subscription – weigh privacy, cost, and how long you need footage.

Privacy settings. Look for end‑to‑end encryption and clear options to delete recordings. A doorbell that streams video to the cloud should let you control who sees it.

Installation is usually a weekend project. Turn off the power at the fuse box, remove the old button, connect the wires to the new doorbell’s terminals (or mount the battery model), and secure the unit. If you’re not comfortable with wiring, a local electrician can finish the job in under an hour.

Pricing in the UK ranges from £70 for basic battery models to £250 for feature‑rich wired units with AI‑powered package detection. Factor in any extra costs for a new transformer, professional install, or monthly cloud fees.

Bottom line: decide whether you want limitless power (wired) or instant install (battery), then match the features to your lifestyle. A good video doorbell not only lets you see who’s at the door, it adds a layer of deterrence that can stop a burglar in their tracks. With the right choice, you’ll get peace of mind and a handy gadget that fits right into your smart home ecosystem.
