The best Door intercoms, compared.
Top pick: Mercury 2-wire audio door phone Best value: TMEZON MZ-V20 7-inch wired video intercom – Wired 7-inch monitor with no app, 4.2 from 416 reviews, at about £79.99, after the missing cable is deducted. Updated October 2026.
A door intercom is an outdoor call station with an indoor handset or monitor, so you can speak to someone at the door and, on many kits, release a separate electric lock. You separate them by the cable in the wall, whether you need a picture, and whether anyone must answer away from home. A one-button house kit does not serve several flats. The cable and the lock are not in that box. The order of the decisions is in the [door intercom buying guide](/hub/electronic-surveillance/door-intercom/sub/door-intercom-buying-guide). Trade two-wire and IP kits are not in this table. Two-wire audio, or a video kit the manufacturer says can reuse a pair, is a different buy from four-wire video. Do not assume an old pair will carry a four-wire camera. The 1,000 m claim on the voice radios is open air. One UK review reported a working gate at about 50 m.

Personal buying guide
Question 1 of 2
Do you need to see the caller?
The Mercury 2-wire audio door phone is an indoor handset and an outdoor panel at £28.99, with a hardwired UK power lead of 1 m and a rain shade in the box. The amazon.co.uk line is 5.0 from 2 reviews. The shorter review says it works very well and the buzzer is clear. The other buyer says previous units of the same make failed from damp even inside an enclosed box, and that they feel stuck with the indoor handset if this third unit fails too. Electronic lock control is stated, and the lock itself is not in the box list. Weatherproof is claimed without an IP code. Two reviews are not a reliability record, so this set does not treat the 5.0 as the top pick. You get a confirmed BS 1363 lead and two-wire speech, and you do not get a picture or a weather test.
Pros
Cons
Best for: You are replacing a two-wire audio phone, you want a stated UK lead, and you will not treat two reviews as a track record.
Less suitable: You need to see the caller, or you need a weather rating written as an IP code.
Specifications
Common questions
Does the box include a UK power lead?
Yes. The box contents list an indoor unit with a hardwired UK power lead of 1 m, plus the outdoor unit, rain shade, fixings, a bracket, and a user guide.
Is a weatherproof rating given as an IP code?
No. The listing says weatherproof and includes a rain shade. It does not state IP54, IP65, or any other IP code. One of the two reviews reports damp failure on earlier units of the same make.
Is the electric lock in the box?
Lock control is stated. The box-contents line does not include an electric lock.
The EZVIZ CP5 is a 7-inch touch video door phone at £161.49, rated 4.4 from 1,330 amazon.co.uk reviews. The listing states a 1080p camera with a 134° view, infrared to 5 m, and unlock from the monitor, from two RFID tags, or from the EZVIZ app. A UK review says the install needs two wires indoors, ideally a twisted pair, so the Wi-Fi on the monitor does not remove the cable to the door. Another UK buyer returned the set because the description had no wiring diagram for the cable already in the wall. The included-components field reads "36 EU", which does not confirm a BS 1363 plug, and the electric lock is not listed in the box. Weatherproof is stated without an IP code. Only two reviews in the scraped file are marked United Kingdom, so the 1,330 figure is the listing total rather than a count of UK-only texts. In this set it is the top pick when you will answer on the wall and on a phone, and a poor match if you want no account and a confirmed UK plug from this scrape.
Pros
Cons
Best for: You can run two or four cores to the door and you need to answer on the monitor or from the EZVIZ app when you are out.
Less suitable: You want no account, a confirmed UK plug from this scrape, or a kit that works with no cable to the door.
Specifications
Common questions
Can you answer this door phone on a mobile?
The listing says you can talk to the visitor and unlock from the EZVIZ app, as well as from the 7-inch indoor monitor.
Does it still need a cable to the door?
The listing states 2-wire installation and compatibility with a 4-wire system. A UK review says you need two wires, ideally a twisted pair, indoors.
Is a UK three-pin plug confirmed?
No. The included-components field in the scrape reads "36 EU", which does not state a BS 1363 plug.
The TMEZON MZ-V20 is a wired 4-wire video kit with one 7-inch monitor at £79.99, rated 4.2 from 416 amazon.co.uk reviews. UK reviewers praise a large, clear picture and a loud chime, and several bought it because it does not call a phone or need a cloud account. The outdoor camera is listed as IP65 with black-and-white infrared, and the listing says you can unlock from the monitor and connect most electronic locks. The lock is not in the box, and the extension cable is not included: a UK review describes the supplied leads as about 4 inches, with little room behind the monitor. One buyer could not use it as a drop-in replacement for a TMEZON system from 2019, and another reported the doorbell push failing after delivery drivers used it. Touch controls stay bright at night and are fiddly when you change a setting. A UK plug is not stated. It is the best value in this set when you are at home, you can run four cores, and you do not need an app.
Pros
Cons
Best for: You are at home, you can run a four-core cable, and you want a 7-inch picture without an app.
Less suitable: You only have one old pair in the wall, you are out all day, or you need the long cable in the box.
Specifications
Common questions
Is the cable between door and monitor included?
No. The listing says the extension cable is not in the box. A 4-pin connector is supplied so you can fit your own 4-wire cable. A UK review describes the leads that are supplied as extremely short.
Does it call a smartphone?
The listing does not state a phone app. UK reviews include buyers who chose it because it has no app, and one buyer who returned it because it would not connect to a phone.
Can you release the door from the monitor?
The listing says you can unlock from the indoor monitor and that the outdoor station can connect most electronic locks. The lock itself is not named in the box contents.
The Dioche wireless voice intercom is an outdoor bell and a portable indoor unit at £38.29, rated 4.2 from 53 amazon.co.uk reviews. There is no camera and no Wi-Fi. UK reviews describe clear speech, a loud bell, and an indoor unit you can carry around the house, including one gate about 50 m from the house that worked. The listing states IP54 and about 1,000 m with no obstruction, plus an outdoor battery of about six months at five presses a day. Reviewers say the batteries do not last as long as that claim, even though one person charged the outdoor unit after about six months. Door release is not stated, and the box-contents line is empty in this scrape. Delivery drivers still ring and leave the parcel without using the intercom, which the kit cannot change. It is a practical voice swap for someone who will not use a smartphone, and the wrong buy if you need to see the caller.
Pros
Cons
Best for: You want speech at the door or a nearby gate, with no app, and you do not need a picture.
Less suitable: A dark step you must see, a lock you must release, or a run you have not range-tested through walls.
Specifications
Common questions
Is there a camera?
No. UK reviews describe it as a voice door intercom. The listing does not state video or night vision.
Is the outdoor unit weatherproof?
The listing states IP54 for the outdoor bell. That is the only weather code given.
Does the indoor unit have to stay by the door?
UK reviews say the indoor unit is portable and can be carried around the house. The listing also claims a long open-air range, which walls will reduce.
The TMEZON two-monitor kit, model MZ-V20*2+MZ-A2, is a 4-wire video set for one family at £135.99, rated 4.1 from 153 amazon.co.uk reviews. The title says a 1-family house with two 7-inch screens and one bell, and a UK reviewer put the second screen upstairs so they did not walk down to answer. The box lists two monitors, two power supplies, a doorbell, a screw bag, a short cable and a 1 m test cable. The extension cable for the real run is not included, and the electric lock is not in the included-components list. Each screen needs its own supply and its own setup, which the UK notes treat as extra work rather than a single pairing. Only three scraped reviews are marked United Kingdom, so the 153 count is the listing total. IP65 and night vision are seller claims, not a test in this file. Bullets that mention apartments do not turn this into a block system.
Pros
Cons
Best for: You already have a four-wire run in one house and you want a screen downstairs and another upstairs.
Less suitable: You only have a single bell pair, you need the long cable in the box, or you are trying to serve two flats.
Specifications
Common questions
Is this two flats, or two screens in one home?
The title says it is for a 1-family house, with two monitors and one bell. A UK reviewer fitted the second screen upstairs in the same home.
What cable is in the box?
The included-components line lists a 1 m test cable, a short cable, two monitors, one doorbell, screws, and two power supplies. The feature text says the extension cable for the run is not included.
Does each monitor need power?
Yes. The box lists two power supplies, and a UK reviewer said each screen needs its own supply and its own setup.
The QingTianTongYun V168M4 is a 4-core wired video kit with a 4.3-inch monitor at £79.99, rated 4.0 from 34 amazon.co.uk reviews. The listing states infrared at 700 TVL, a rain cover, 25 ringtones, do-not-disturb, and a cable run of up to 100 m. One UK review calls the picture very good by day and at night and the install easy. Other UK notes say a unit did not work at all, another failed after a few weeks, and a matching-looking unit in a rented flat rang at random until it was unplugged and lost its settings when the power went off. The parts list includes a 3-pin UK adapter, while a feature bullet says the power supply is not included, so those lines conflict. The electric lock and the exit button are excluded. There is no IP code. At the same £79.99 as the TMEZON 7-inch kit, the smaller screen and the failure notes are why it is not the best value row.
Pros
Cons
Best for: You can run four cores, you want a stated UK adapter, and you accept a small, mixed review file.
Less suitable: You want the 7-inch review file at the same price, or a listing whose power-supply lines agree.
Specifications
Common questions
Is the electric lock included?
No. The listing says the package does not include the electric lock or the exit button. It does say the monitor can connect a lock.
Is there a UK plug?
The included-components line lists one 3-pin UK power adapter, plus the monitor and the outdoor camera. A feature bullet also says the power supply is not included, so those two lines conflict.
How far can the camera be from the monitor?
The listing states a maximum of 100 m using a 4-core cable.
The Winnes 24A08016 is a pre-paired wireless video doorbell with a 4.3-inch monitor at £52.99, rated 3.8 from 378 amazon.co.uk reviews. The listing says it needs no Wi-Fi, no app and no subscription, with 1080p, a 170° view, night vision to 5 m, and an open-air range of up to 80 m that walls reduce. UK reviews describe a usable daytime picture and a night view that is enough to see a visitor, and one buyer said the two units had to be very close together before they would work. Door release is not stated. The outdoor bell slots onto the bracket and is not locked, so UK reviews say it can be lifted off, and the securing screw is described as too small. There is no battery-level indication, one review says no power pack was in the box, and push-to-talk failed in one direction for another buyer. A microSD card is not included; without one the monitor stores up to 50 photos. It is the set's no-cable video option when you do not need to release a lock, and a weak choice if the bell must stay on the wall.
Pros
Cons
Best for: You cannot run a cable, you will answer on a small indoor screen, and you do not need to unlock the door.
Less suitable: You need a lock release, a bell that is locked to the wall, or a picture when the two units are far apart through brick.
Specifications
Common questions
Does this video doorbell need Wi-Fi?
The listing says it is pre-paired and needs no Wi-Fi, no app, and no subscription. The indoor monitor is how you see and talk.
Is a memory card in the box?
No. Without a card the monitor stores up to 50 photos. A TF card, not included, is what the listing says you add for video, up to 32 GB.
Can it unlock the door?
Door release is not stated on this listing. The included parts are the camera, the display, a USB cable, and an installation kit.
The Fockety wireless voice doorbell is a rechargeable outdoor bell and a press-to-talk indoor unit at £30.79, rated 3.4 from 35 amazon.co.uk reviews. The listing claims about 1,000 m with no barrier, frequencies of 434 MHz and 462 MHz, and about eight months on the outdoor battery at five presses a day. UK reviews do not support that battery line: one unused unit needed charging after a day, another charge lasted about five minutes, and an outdoor battery lasted about five hours after a month and then failed again. There is no charge indicator, and one review says the bell is hard to turn off so it keeps ringing. One short review calls the range good on an outdoor gate when the unit works, and another buyer could not return a dead unit because the packaging had been thrown away. No camera, no IP code, and no door release are stated. The lower price against the Dioche is not a saving if the outdoor cell dies in days.
Pros
Cons
Best for: You want the cheaper voice radio kit and you will charge it often after a range test.
Less suitable: You need a picture, a stated weather code, or a battery claim you can trust from the UK reviews.
Specifications
Common questions
Does this doorbell show a picture?
No. It is a voice intercom doorbell. The listing does not state a camera, a screen, or night vision.
How long does the battery last?
The listing claims about 8 months on the outdoor unit at five presses a day. UK reviews report charges lasting hours, a day, or about five minutes, not months.
Is an IP rating stated?
No. The listing does not give an IP code for the outdoor bell.
Shelf prices, stars and review counts are the amazon.co.uk listings for these eight door intercoms, read on 19 October 2026. A wider set of listings was looked at and not kept on this page. This is not a lab test. None of these listings shows a test to BS EN IEC 62820-1-1. An IP54 or IP65 line is seller text, not a weather result. A 5.0 from two reviews is not scored above 4.4 from 1,330. Weights sum to 100.
Amazon evidence
30%Star rating on amazon.co.uk, then a deduction when the count is tiny or when almost none of the scraped reviews are marked United Kingdom. A 5.0 from two reviews is not scored above 4.4 from 1,330.
Door-entry fit
35%A real outdoor station, a stated cable count or a local radio claim, speech, and a stated unlock where the listing claims one. A missing extension cable, a missing lock, an unconfirmed BS 1363 plug, or a box line that contradicts the title loses points.
Review outcome
20%UK reviews that describe a finished call score higher than a damp failure, a battery that dies in hours, a bell that lifts off its bracket, or a return because the wiring diagram was missing.
Value
15%Shelf price in GBP against a job a UK review can finish. The lowest price does not win this block when the outdoor unit failed or the sample is two reviews.
Buy the dwelling, the cable and the picture before the lowest sticker. These eight amazon.co.uk listings run from a two-wire audio handset at about £28.99 to the EZVIZ CP5 at about £161.49. The top pick is the CP5 when you will answer on the monitor and on a phone. Best value is the TMEZON MZ-V20 when you are at home, you can run four cores, and you do not want an app. Voice is enough if you can still see the caller. A one-button house kit does not serve several flats.
A door intercom is an outdoor call station paired with an indoor handset or monitor. You use it to speak to someone at the door. On many kits you can also release a separate electric lock. The lock is usually a second purchase. Voice-only kits in this set are about £29 to £40. Video kits are about £53 to £80. A two-monitor kit or a Wi-Fi door phone is about £136 to £162. Those bands are the eight amazon.co.uk listings kept here.
A door intercom in this set is an outdoor station plus an indoor handset or monitor. A replacement handset on its own does not give you a call point at the door. Check the box line for the outdoor unit before you order.
The TMEZON and QingTianTongYun listings are four-wire. The Mercury listing is two-wire audio. EZVIZ states both two-wire and four-wire installation. An old bell pair will not carry a four-wire camera just because both ends are labelled door phone.
The electric lock is not in any box in this set. On the TMEZON kits the extension cable is not included either. UK reviews of the single-monitor TMEZON call the supplied leads about 4 inches. A 1,000 m range line is open air, not a through-wall result. A house kit on a shared door is the wrong object.
Start with how many homes the door serves. A single call button is one household. A block needs a directory or a multi-button panel for that entrance. Two monitors in one house, which is what the TMEZON two-screen kit is titled for, are not two flats. Bullets that mention apartments do not turn that box into a block system. Then the cable already in the wall. Two-wire audio, the Mercury listing, is a different buy from four-wire video.
Where the answer happens is the next decision: a fixed handset, a portable indoor unit, a second monitor upstairs, or a phone app. Only the EZVIZ CP5 listing in this set states a phone app and remote unlock. UK reviews of the wired TMEZON kit treat no app as a reason to buy. The Mercury is a corded handset. The Dioche indoor unit is portable. The two-monitor TMEZON is for one house, with each screen on its own supply.
Three typical situations, each with a recommendation from this comparison.
You are replacing a dead audio handset, or adding a first video monitor, and you can reuse a cable. You do not want an account. The TMEZON MZ-V20 is a wired 7-inch kit at about £79.99, with 4.2 from 416 reviews. The extension cable and the lock are not in the box, and a UK plug is not stated.
You are buying for someone who will not use a phone. The Dioche is voice only, with a portable indoor unit, at about £38.29 and 4.2 from 53 reviews. There is no picture and no unlock stated. UK reviews say the battery is shorter than the six-month claim.
You control only your own entrance, and you need permission before you drill. The Winnes is a no-Wi-Fi video bell and a 4.3-inch monitor at about £52.99, with 3.8 from 378 reviews. Door release is not stated, and UK reviews say the bell lifts off the bracket. A shared street door is a different system.
The top pick is the EZVIZ CP5 at about £161.49. It scores highest here: a 7-inch touch monitor, unlock from the screen, two RFID tags or the EZVIZ app, and 4.4 from 1,330 amazon.co.uk reviews. The UK plug is not confirmed, and only two scraped reviews are marked United Kingdom. Best value is the TMEZON MZ-V20 at about £79.99, a wired 7-inch monitor with no app, IP65 stated, and 4.2 from 416 reviews, after the missing extension cable is already deducted. The Dioche ties that score and stays a voice-only kit. A 5.0 from two Mercury reviews is not the top pick. None of these listings claims BS EN 62820, and the electric lock is not in the box.
TMEZON MZ-V20 7-inch wired video intercom
Wired 7-inch monitor with no app, 4.2 from 416 reviews, at about £79.99, after the missing cable is deducted.
