Installing a video doorbell is one of the easier upgrades in a DIY system, as long as you handle the one risky part correctly: the wiring. A battery model needs only a bracket and a screw; a wired model uses your existing doorbell cables and a low-voltage transformer. This guide covers both, with the safety checks that manufacturers insist on. It is part of our DIY home security setup guide.
Battery or wired?
- Battery: no wiring, so it suits renters, but you recharge or replace the battery. Pair it with a chime or hub for sound inside.
- Wired: constant power and no battery chores, but it needs compatible wiring. Blink, for example, says its wired doorbell needs 16 to 24 volts AC at up to 40 VA from your transformer, and that the transformer voltage must match the chime.
Choose your model first; see video doorbells without a subscription for how recording and fees work.
Before you start: check compatibility
- Find the indoor chime and the transformer and read the voltage rating on the transformer.
- Compare it to the range the doorbell requires. Ring's UK guide says a transformer outside the 8 to 24 volt AC range is not compatible and you should consult a qualified electrician; a chime wired straight to 230 volts without a step-down transformer is not compatible either.
- Photograph the existing chime wiring so you can restore it later. Ring advises restoring the chime wiring if you ever uninstall the doorbell.
Installing a wired doorbell
- Turn off the power. Switch off the breaker that feeds the doorbell and chime. If you do not know which one it is, Ring suggests turning off the master breaker, then pressing the doorbell button: if the chime does not sound, the power should be off. Anker's guide also recommends confirming with a voltage tester.
- Prepare the chime. Many video doorbells need a chime kit or bypass inside the indoor chime. Lorex has you install it before touching the outside unit. Ring notes that its bypass isolates your existing chime, so a mechanical chime may stop ringing.
- Remove the old button and keep the low-voltage wires from falling into the wall.
- Fit the mounting bracket with the supplied screws, using wall anchors on brick or concrete.
- Connect the wires to the doorbell. Polarity does not matter on AC, according to Eufy. Lorex says to seal any exposed wiring with electrical tape.
- Restore power at the breaker, then finish setup in the app.
- Test the button, the chime and the live video.
If Blink's app shows "Wired power not supported," your existing chime wiring is not compatible. If anything is unclear, hire a licensed electrician.
Installing a battery doorbell
- Charge and insert the battery, then add the doorbell to the app.
- Check Wi-Fi at the door before drilling; see how to secure smart home devices for router tips.
- Mount the bracket, attach the doorbell and test the view.
- Set motion zones so passing cars do not trigger constant alerts.
Placement and settings
- Cover the approach to the door; see where to place security cameras.
- Use a strong account password and two-factor sign-in.
- Consider a gate or perimeter camera as well; see gate and perimeter security.
- Renters should ask permission before drilling or changing wiring; see home security for renters.
Video doorbell installation checklist
- Transformer voltage matches the doorbell's requirement.
- Power was off, and checked, before touching wires.
- Chime kit or bypass installed if required.
- Exposed wiring sealed.
- Button, chime and video tested.
- Password and two-factor sign-in set.
Frequently asked questions
Can I install a video doorbell without an existing doorbell?
Yes, with a battery model. A wired one needs a low-voltage power source.
Why does my indoor chime not ring?
The chime may be bypassed, incompatible or missing a kit. Check the manufacturer's guide for your model.
Is it safe to do myself?
Low-voltage doorbell wiring is usually a DIY job, but turn off the power first. Hire an electrician if you meet mains-voltage wiring or are unsure.
