A screen inside the house works when the phone is upstairs on charge
An intercom is a doorbell that answers on a screen fixed to your wall rather than on a phone, which is the whole point: it works when the phone is charging in another room, and it works for people who do not want an app. The installation detail that decides the job is the wiring — a two-wire system reuses an existing bell cable, a four-wire one usually does not. The second is gate release: whether the monitor can drive an electric strike, and on which contact. We compare monitor size and clarity, wiring type, gate release output, multi-monitor support and recording to card.
1080p · 7-inch color touchscreen · 134° view · remote door and gate release · two-wire and Wi-Fi
A 7-inch touchscreen indoor monitor with a 134° outdoor unit and a gate release output, wired to the door over two wires (four-wire compatible) and joined to the router over dual-band Wi-Fi. EZVIZ states 1080p, night vision and two-way audio with voice change.
Best for: A house that wants a screen on the wall rather than an app, with a two- or four-wire cable already running to the door.
Audio only, NO screen · N/O dry contact rated 30 V AC/DC 1 A — the only door-release contact rating on this shelf · 2-conductor shielded wiring, with Aiphone #822202 (22AWG) or #821802 (18AWG) named · push-to-talk simplex · master station 7-1/16 × 5-5/8 × 2-1/8 in, door station 4-3/4 × 3-1/2 × 1-1/8 in
The only intercom on this shelf that tells you what its door-release contact is rated for — and the only one with no screen at all.
Best for: A gate or an entrance where the job is to speak and release, and a specified strike contact matters more than a picture
≈ $150
One outdoor camera and SIX 7-inch indoor monitors, one building of six households · stated support for up to 12 monitors, the highest expansion on this shelf · 700TVL CMOS night vision · the RVV-4 interconnect cable is NOT included and AMOCAM names the separate listing to buy it from
Six monitors in the box and twelve supported — the most expansion on this shelf, by a factor of six, at four hundred dollars less than the most expensive single-door kit.
Best for: A small block of six apartments, or a large house that wants a monitor on every floor
≈ $425
TWO 7-inch touch monitors and one outdoor camera · 4-wire surface mounting, rain cover and terminals supplied · 92° aluminum and acrylic vandal-resistant panel · 16 chimes · the monitor CANNOT drive a strike, bolt or magnetic lock without a separate power supply controller — stated
Two touch monitors for a hundred and fifty-six dollars, on a listing that admits its own release output will not drive most locks.
Best for: A two-floor house with four conductors already run, where a touch screen beats a row of buttons
≈ $156
7-inch LCD at 800 × 480 — the only screen resolution published on this shelf · one monitor, one camera · 4-wire surface mounting, rain cover and terminals supplied · 92° aluminum and acrylic panel · the monitor cannot drive a strike, bolt or magnetic lock without a separate controller — stated
The cheapest video intercom here at eighty-two dollars, and the only one that says how many pixels its screen has.
Best for: A single-entrance house with four conductors already run, on the smallest budget that still gets a screen
≈ $82
2-wire, reusing existing bell cable · TWO 7-inch touch monitors with room-to-room calling · 1080p camera, 140°, IP65 with a rain hood · SD card included, no subscription · Tuya app and RFID tags for entry · screen resolution not published, release contact not rated
Two 7-inch touch screens on two wires, with the card in the box — the shelf's cheapest route to a monitor on two floors.
Best for: A two-story house with an existing bell cable, where the kitchen and the bedroom both need a screen
≈ $210
One outdoor panel with DUAL CALL BUTTONS for two households, each with its own 7-inch touch monitor · 2-wire on existing bell wiring · dual-band Wi-Fi 6 · 1080p, 140°, IP65 · human detection · SD card included, no subscription · Tuya app and RFID keycards
Two call buttons on one panel and a private monitor for each household — the only two-dwelling system on this shelf under four hundred dollars.
Best for: A duplex, a converted house or an annexe, where two households share one front panel and share nothing else
≈ $250
Flush-mounted outdoor unit · 150° Full HD · 7-inch monitor · app · IP54 and IK07 · tamper alarm
A complete single-family set with a flush-mounted outdoor station, a 150° Full HD camera, a 7-inch monitor and app access. Balter states IP54 and IK07 ratings and a tamper alarm on the outdoor unit.
Best for: A new or renovated entrance where a recess can be cut and the outdoor unit should sit flush in the wall.
Surface-mounted outdoor unit · 150° Full HD · two 7-inch monitors · app · IP54 and IK07
The surface-mounted version of the ENTRI set, supplied with two 7-inch monitors. Same 150° Full HD camera, same IP54 and IK07 ratings, same tamper alarm — and no recess to cut.
Best for: An existing house with two floors, where cutting into the wall is not on the table.
2K · 7-inch touchscreen · 162° view · three ways to open · person detection with custom zones
The 2K version of EZVIZ's intercom, with a 162° field of view and three ways to release the door — from the monitor, from the app, or with the supplied RFID card — plus person detection with a user-defined area.
Best for: The same job as the CP5 with a wider, sharper image and a detection zone that can exclude the pavement.
2-wire bus · two 7-inch touch monitors · surface-mounted outdoor unit · 2 MP sensor · expandable
A two-wire bus system with two indoor monitors, designed to reuse an existing bell cable rather than needing new conductors. Goliath states a 2 MP sensor, capacitive touchscreens and expansion with further indoor or outdoor stations.
Best for: A house with an existing two-core bell cable and two floors that both need a panel.
7-inch master station · die-cast aluminum vandal-resistant door station · 24 V DC · 165 ft on 22AWG, 330 ft on 18AWG — the only cable run length on this shelf · 30 stored still images · expandable to 1×2 only · the page lists JV-series parts in its bullets and JO-series parts in its description
The only listing here that tells you how far the cable can run — on a page that names two different product families for the same box.
Best for: A long cable run to a gate, where the distance figure and die-cast construction justify seven hundred dollars
≈ $700
2-wire bus · four apartments · four 7-inch monitors · 140–170° fisheye · Full HD · Tuya app
A four-apartment two-wire system with four 7-inch touchscreens and a fisheye outdoor camera stated at 170° in the listing title and 140° in its description. MATHFEL states automatic recording on motion or on a ring, with playback from the monitors or the Tuya app.
Best for: A converted house or small block with four separate dwellings on one entrance.
The panel camera decides whether a visitor is recognized, often against the light. Both LUMOBELL kits state 1080p with a 140-degree wide angle, the widest stated on this shelf.
LUMOBELL 2W_KW02_IP7 two-wire video intercom with dual 7-inch touch screens
Every screen on this shelf is 7 inches, so size settles nothing. What changes is how many come in the box: the AMOCAM 70H-M42 ships two touch screens on four-wire, the LUMOBELL 2W_KW02 two on two-wire.
AMOCAM 70H-M42 wired video door phone system, 7-inch touch screen, two monitors
A four-wire intercom will not go onto a two-wire installation without pulling new cable. Both LUMOBELL kits run on two wires, stated to use existing doorbell wiring; the AMOCAM kits need four.
LUMOBELL LMIP7_08C_2F two-wire two-family video intercom with 7-inch touch screens
Wired systems need a cable between panel and monitor, which is the real installation work. Radio models avoid it, with the limits of a wireless link.
Conventional systems do, entirely. Only the remote answering functions depend on it.
Most monitors have a control output. Connecting it to the gate automation depends on the equipment already in place.
The immediate space in front of the door or gate. It must not frame the public road or a neighbor's property.
Panels generally have built-in short-range lighting. Against the light in daytime, the image is often harder.
Flush panels with a metal front stand up markedly better. It is a criterion on a gate at the roadside.
Most door panels feed two monitors, some four, and beyond that a separate supply is needed. The stated monitor count is checked before wiring an upstairs unit.
A conventional intercom works entirely without internet: only remote answering depends on it. The cable between panel and monitor is the real work, and the panel camera must frame neither the public road nor a neighbor's property.
There is no table here, and the reason is in the listings. The figure published most often across these 13 products is access control, given by 10 of them — short of the four in five a column needs to compare rather than to display gaps. Each product page says what its own maker published.
