The best 3 apartment intercom systems, compared.
Top pick: Digiteck 903 3-way audio Best value: uoweky 4.3 inch, 3 monitors – Lowest shelf price among those reviewed three-monitor video kits, at £200.99, after buzz and adapter notes are already in the score. Updated October 2026.
A 3 apartment intercom system is a door-entry kit for three dwellings that share one entrance. You fit an outdoor station, one indoor station per flat, and a way to release the door. Speech-only, a four-wire video door phone, and a trade two-wire or system are different products. Quality is the match to the building: the right number of indoor stations, a cable the conduit can hold, a lock that fails in the safe direction, and a camera that does not film the pavement. Cable, lock, weather and privacy are set out in the [3 apartment intercom buying guide](/hub/electronic-surveillance/3-apartment-intercom-system/sub/3-apartment-intercom-system-buying-guide). Specialist 3-flat video outside this shop sits higher. The variation line must say one outdoor station and three indoor stations, or it must be a true three-flat audio layout. Up to 12 and 3-way are not that count. The box line lists an outdoor unit, an indoor electric lock kit and a power supply. It does not state three handsets, and the number-of-items field is 1. The 10 inch title says three monitors and a bullet says two indoor screens. Both lines are on the same listing, so the station count is not settled.

Personal buying guide
Question 1 of 2
Do you need a picture of the caller?
The Digiteck 903 is an audio door phone at £194.00, rated 4.4 from 12 amazon.co.uk reviews, with no camera on the listing. The box line includes an outdoor unit, an indoor electric lock kit, and a power supply, which is the only kept listing that states a lock in the box. The name says 3-way and the features line says three-way communication, but the box line does not say three indoor handsets, and the number-of-items field is 1. Three captured UK reviews, from 2017 to 2019, say it worked, included the parts an installer needed, or was right for the job. One of those reviews is only Ok. No fault is described in that small set, and fail-safe or fail-secure is not stated. Water resistant is claimed with no IP code.
Pros
Cons
Best for: You want speech and a lock kit in the box, and you have confirmed how many handsets you will actually receive.
Less suitable: You need a picture of the caller, or a listing that states three indoor stations.
Specifications
Common questions
Is this a video intercom for three flats?
It is an audio door phone. The name says 3-way. The box line lists an outdoor unit, an indoor electric lock kit, and a power supply. It does not state three indoor handsets.
Is the lock included?
Yes. The title and the box-contents line include an electric lock kit and a power supply. Fail-safe or fail-secure is not stated.
What do the captured reviews say?
The listing is 4.4 from 12 reviews. The three captured UK reviews, from 2017 to 2019, say it worked or was right for the job. They do not describe a fault.
The uoweky V70N is listed at £209.99 as one outdoor camera and three 7 inch indoor monitors for three households, and it sits at 3.6 from 93 amazon.co.uk reviews. That station count, the 7 inch screen, and the largest review file among the three-monitor kits make it the top pick in this amazon.co.uk set, which is a listing comparison and not a lab test. Reviewers call the picture good and the night picture usable, though most written reviews are from outside the United Kingdom. One detailed review measured about 3 V on the lock terminals at rest and about 12 V when the button was pressed, and a gate stayed open until a relay was added. The same notes describe about 12 cores to the outdoor station, wall plates that miss a standard back box, and an outdoor housing that needed silicone and a canopy. Other reviews mention a dead screen on arrival, a monitor that went blue after a few months, and a button that rang a second flat. The lock is not in the box, and waterproof is claimed with no IP code.
Pros
Cons
Best for: You want a reviewed kit that states three indoor monitors and a 7 inch screen, and you will add the lock and the weather cover yourself.
Less suitable: You need a printed IP code, a dry contact for a gate, or a quiet install into a standard back box.
Specifications
Common questions
How many flats is it described for?
The style line and the bullets say one outdoor camera and three indoor monitors for three households.
Is it waterproof?
The camera bullet says the outdoor station is metal and waterproof. No IP code is printed.
What do reviewers say about the lock output?
One detailed review measured about 3 V on the lock terminals at rest and about 12 V when the button was pressed, and added a relay before an automatic gate would stay shut. Other reviews mention a dead screen, a blue screen later, and a button that rang a second flat.
The uoweky model 168 is a wired 4.3 inch kit at £200.99, rated 3.5 from 77 amazon.co.uk reviews. The bullets say three call buttons, each calling one indoor monitor, which is the clearest three-apartment statement at this price in the set. Reviewers describe picture and speech as acceptable, including at night, and the specification line lists night vision at 2 m beside an IP54 claim. A UK review from 21 June 2022 describes a continuous buzz that a neighbour could not stop, and other notes say the bell will not go quiet and the lamp will not switch off. Written reviews are mostly from outside the United Kingdom. Owners also report one adapter per handset, cable that will not fit an existing conduit, weak rain protection, and units that later ring on their own or stop ringing after about a year. The lock is not in the box. On price against a stated three-monitor video kit, it is the best value in this set.
Pros
Cons
Best for: You want the cheapest reviewed three-monitor video kit in this set and you can live with a buzz and separate adapters.
Less suitable: You need a quiet bell, a two-wire riser, or a lock in the box.
Specifications
Common questions
Is it sold for three flats?
The bullets say three call buttons, each connected to one indoor monitor, and that this suits three apartments.
Does it include the electric lock?
The bullets say you can connect an electric lock and open it from the monitor. The lock is not listed as included.
What do the reviews repeat?
The listing is 3.5 from 77 reviews. Repeated themes are a constant buzz, weak rain protection, many cables and separate adapters, and units that later ring on their own. Most written reviews are not from the UK.
The ANJIELO SMART 520-705 variation is sold as one doorbell and three 7 inch hands-free monitors at £285.99. The captured amazon.co.uk page has no star line and no review text, so you are buying the variation title rather than a record of three-flat installs. A bullet states 960p, night colour, a 5 m lead, and a 60-second cut-off if nobody answers. The title says wired, while the specification block says Wi-Fi, and a bullet says IP65 where the specification block prints no IP code. The included-components line lists a doorbell and a monitor, not three monitors and not an electric lock. The lock bullet says you need a separate power controller. The wider title also names kits from 2 to 12 units, so the wrong variation is the risk you check before you pay.
Pros
Cons
Best for: You have confirmed this variation is the three-monitor kit and you can add a lock power controller.
Less suitable: You want UK review text, one wiring story, or a lock in the box.
Specifications
Common questions
How many monitors does this variation include?
The variation title says 1 doorbell and 3 monitors. The broader title also names kits from 2 to 12 units, so check the variation before you order.
Is the electric lock in the box?
The bullets say it works with an electronic lock and that you need a power controller. The included-components line lists a doorbell and a monitor, not a lock.
Does the listing show a star rating?
The captured amazon.co.uk page has no customer-review line, so the rating is n/a.
The ANJIELO SMART 530-168 is listed at £299.99 with a title that says one doorbell and three 4.3 inch monitors. The captured page has no star rating and no review text. Bullets describe hands-free and handset speech, 25 ringtones, and electric unlocking from the monitor. The specification line says 1080p while the camera bullet says 700TVL CMOS night vision, and the title says wired while the specification block says Wi-Fi. The included-components line names only the doorbell, the number-of-items field is 4, and the page also prints 100 kg and 50 x 10 x 100 mm. Those two figures are listing errors, not a measured weight or size. A capacity bullet says up to 12 devices and tells you to contact the seller above six, and waterproof is claimed with no IP code.
Pros
Cons
Best for: You want the 4.3 inch three-monitor title and you will ignore the weight and size fields.
Less suitable: You need reviews, a parts list that matches the title, or a screen larger than 4.3 inch.
Specifications
Common questions
Is this the three-flat kit?
The title says 3 units and 1 doorbell plus 3 monitors. The number-of-items field is 4 and the included-components line names only the doorbell.
What screen and calling styles are listed?
A 4.3 inch monitor with hands-free and handset calling, and 25 ringtones, is what the bullets describe.
Should you use the listed weight?
The specification block prints 100 kg and 50 x 10 x 100 mm. Those figures are on the page and are not a measured weight or size.
The ANJIELO SMART 94229 is listed at £599.99, the highest price in this set, and the captured page has no star line and no review text. The title says one white doorbell and three black 10 inch monitors. A bullet says one outdoor camera and two indoor 10 inch screens for two occupants. Both lines are on the same listing, so you cannot treat this as a confirmed three-flat kit until the seller confirms the count. Where the page is consistent, it states four wires from monitor to doorbell, 3 m of four-core cable per doorbell, Wi-Fi on the main monitor for phone viewing, 1080p, unlock by ID card, app, and monitor, and a 32 GB card in the recording bullet. A rain cover is stated and no IP code is printed. The included-components line says doorbell, not three monitors.
Pros
Cons
Best for: You have written confirmation that the parcel is the three-monitor version and you want the stated app and card.
Less suitable: You need a listing whose station count agrees with itself, or a reviewed kit under £210.
Specifications
Common questions
Do you get two monitors or three?
The title says 3 units and 1 doorbell plus 3 monitors. A bullet says 1 outdoor camera and 2 indoor screens for two occupants. Both lines are on the listing.
How is it wired?
The wiring bullet says four wires from monitor to doorbell, with 3 m of four-core cable supplied per doorbell and a 1.2 m power lead per monitor.
Can you view it on a phone?
The same bullet says the main monitor can join home Wi-Fi so you can view visitor information on a phone. No review text is on the captured page.
Six amazon.co.uk listings were scored from the stored pages and the review notes already on file. Shelf date 19 October 2026. There is no laboratory test. A trade-shop price is context only and is not a score. The highest score is the top pick among kits that state three indoor monitors and have review text. It does not mean the safest door-entry system in the UK. The best value is the lowest shelf price among those same reviewed three-monitor video kits, after the fault pattern is already in the score. One of each. The weights below sum to 100.
Amazon evidence
25%Star rating and review count on amazon.co.uk. A missing rating line scores low. A small sample, or written reviews that are mostly not from the United Kingdom, is a deduction.
Fit for three dwellings
40%A stated one-outdoor and three-indoor kit scores higher. A title that clashes with a bullet, a parts line that does not match the title, a Wi-Fi line on a wired kit, or a 3-way name that does not list three handsets, is a deduction.
Review outcome
20%A captured note of a finished install scores higher than a file that repeats buzz, weather trouble, a dead screen, cross-ringing, or a lock voltage that would not hold a gate. No review text cannot earn this block.
Value
15%Shelf price in GBP against a kit whose station count you can actually read. A low price does not score when the handset count is unproven. A high price does not score when the page disagrees with itself.
Match the station count, the cable and the lock before you match the screen size. Prices below are amazon.co.uk shelf prices on 19 October 2026, plus trade-shop context that is not a score. This is not a laboratory test.
A 3 apartment intercom system is for three dwellings on one entrance. You need an outdoor station, one indoor station per flat, and a release for the door. Speech-only, a four-wire video door phone, and a trade two-wire or PoE system are different products. The six amazon.co.uk listings kept on 19 October 2026 run from £194.00 for the Digiteck audio kit to £599.99 for a 10 inch ANJIELO SMART listing. Specialist 3-flat video outside this shop sits higher.
Up to 12 and 3-way are not an indoor-station count. The variation line has to say one outdoor station and three indoor stations, or a true three-flat audio layout. The Digiteck box line does not state three handsets.
Works with an electric lock does not mean the lock is included, that the output is a dry contact, or that it releases on a fire alarm. Only the Digiteck listing states a lock kit, and it does not say fail-safe or fail-secure.
A four-wire kit wants a home-run toward each monitor. A short seller lead is not a riser loom. If the conduit is full, the kit will not shrink to fit. A two-wire bus or PoE system is a different product.
Count the stations on the variation you will actually order. The uoweky V70N style line says one outdoor camera and three indoor monitors for three households. The uoweky 4.3 inch bullets say three call buttons, each calling one monitor. The Digiteck name says 3-way and the box line does not say three handsets. The ANJIELO SMART 10 inch title says three monitors and a bullet says two.
Fail-safe unlocks when power is lost. Fail-secure stays locked. Only the Digiteck box line states a lock kit, and it does not name either behaviour. One V70N review measured about 3 V on the lock terminals at rest and about 12 V when the button was pressed, and a gate needed a relay. Quote only the IP code the ASIN prints. The 4.3 inch uoweky prints IP54. The V70N says waterproof and prints no IP code.
Three typical situations, each with a recommendation from this comparison.
You are replacing a dead audio system and you want a picture of the caller. The uoweky V70N states three 7 inch monitors and one outdoor camera at £209.99, with 3.6 from 93 reviews. You still add the lock, and no IP code is printed.
You are comparing a kit near £200 with specialist 3-flat video around £825 to £1,022. Screen size is not that gap. The uoweky 4.3 inch kit is £200.99, states three monitors, prints IP54, and sits at 3.5 from 77 reviews. Buzz and separate adapters are already in the notes.
You want speech at a shared door and you do not want a camera on the pavement. The Digiteck 903 is £194.00, with 4.4 from 12 reviews, and the box line includes an electric lock kit and a power supply. It does not state three handsets.
The top pick is the uoweky V70N at £209.99. It states three 7 inch indoor monitors and one outdoor camera, with 3.6 from 93 reviews, and it scored highest among kits that state three indoor monitors and have review text. The best value is the uoweky 4.3 inch kit at £200.99, the lowest shelf price in that same reviewed group, with IP54 printed and 3.5 from 77 reviews. The Digiteck 903 at £194.00 includes a lock kit and has no camera, but the box line does not state three handsets. None of these scores is a laboratory test.
uoweky 4.3 inch, 3 monitors
Lowest shelf price among those reviewed three-monitor video kits, at £200.99, after buzz and adapter notes are already in the score.
