Video intercom electric lock release UK

Updated: 23 October 2026

You press the indoor monitor button and expect the front door to click open. On these kits, a video intercom electric lock release UK is a second purchase. The button, the tag or the app only switches a strike or a maglock that was not in the carton, and people still have to get out if that door is the way you would leave in a fire. The [single household video intercom system](/hub/electronic-surveillance/single-household-video-intercom-system) table shows which listings claim a release. This page stays on the lock. A qualifying purchase through our links can earn us a commission at no extra cost to you.

The button is not the lock

Read the included-components line, not the word unlock in the title. Both TMEZON kits claim unlock from the indoor monitor, and neither box contains a strike. ReaIOKbii says the same. KurDunly unlocks via the Tuya app. EZVIZ names two RFID tags, the monitor and the app. The included line says 36 EU and does not name a strike. Hikvision’s box is the door station, the monitor and two power supplies. The V168 says the electric lock, the exit button and the power supply are not included, while another line lists a 3-pin UK adapter. JASAG is indoor key only, and outside unlocking is not supported. Winnes and LUCINE do not state a lock output.

Match the lock to the output you can prove

Voltage and the contact type come from the lock you buy and from the manual of the door station you actually have, not from a guessed milliamp figure. An ESP Aperta manual shows the pattern on that station: normally closed for a maglock, normally open for a strike, and a 12 V DC output limited to 300 mA. Those limits are not these kits. Do not copy 300 mA onto TMEZON, EZVIZ or Hikvision. Hikvision’s 12 V DC and 10 W line is the kit supply, not a lock current. Do not use Aiphone colours on a TMEZON tail. A 12 V strike can still be the wrong 12 V if it is AC rather than DC, or if the station cannot supply the current. If the manual does not state the output, you do not have a figure to match. Cable type is chosen on the wired or Wi-Fi video intercom page.

An escape door is a different rule

Fail-secure means the door stays locked when power fails. Fail-safe, or power-to-lock, opens when power is removed. Paxton’s escape note states the principle: a fail-secure lock is not the escape method, and a request-to-exit button is not a break-glass. If the door already has panic hardware to BS EN 179 or a panic exit device to BS EN 1125, escape does not depend on the intercom. The NSI note says BS 7273-4 is the fire-alarm interface where escape depends on powered locking, and it is not a substitute for mechanical escape hardware. Do not put a fail-secure device on a door that must open when the power fails, including a front door you would use to leave in a fire, until someone competent tells you it is not an escape route.

When not to connect it yourself

Call an electrician, or the person who already maintains that door, when the release is on an escape route. A lock on an escape route is not a plug-in monitor job. Call them too when you do not own the leaf, the frame or the cable in a block. You can still plan the purchase: confirm the listing omits the lock, buy a strike whose voltage the manual states, and keep fail-secure off the escape door. The Consumer Rights Act 2015 does not make a missing strike a fault if the listing never included it. A monitor that will not switch the output the manual describes, once a correct lock is connected, is a different complaint.

Common questions

Is the electric lock in the video intercom box?
On these amazon.co.uk listings, no. TMEZON, ReaIOKbii, KurDunly, EZVIZ and Hikvision claim a way to unlock and leave the strike out of the included list. The V168 says the electric lock and the exit button are not included. JASAG does not support outside unlocking. Winnes and LUCINE do not state a lock output. Budget for a separate release, or accept a speak-only door.
What is the difference between fail-secure and fail-safe?
Fail-secure stays locked when power fails. Fail-safe, or power-to-lock, releases when power is removed, which is how many maglocks behave. A strike that needs a pulse of power to open will not open in a power cut. It is the wrong device on a door people need when the lights go out.
Can I put a powered lock on the door I would use in a fire?
Not a fail-secure one, and not a doorbell relay standing in for escape hardware. If escape depends on the lock losing power, that interface is a specified system, and BS 7273-4 is not a substitute for a mechanical panic device where the door already needs one. A request-to-exit button is not a break-glass. If you are unsure whether the door is an escape route, stop and ask an electrician before you connect anything.
Does JASAG open the door from outside?
No. The listing says indoor key only, and outside unlocking is not supported. It can still be a 7 inch wired monitor for seeing and speaking, at £58.03 on the day we captured it, on a file of six ratings. It is not the kit you buy because a bullet on a different brand says connect an electric lock.
Who should wire the release?
An electrician, when the door is an escape route or when you do not own the door and the cable in a block. A competent householder can connect a stated extra-low-voltage output to a matching strike on a private door that is not the escape route, using the manual for that station, after the monitor already works on the bench.
