A screen inside the house works when the phone is upstairs on charge · review
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.
The conclusion Six 7-inch monitors for four hundred and twenty-five dollars works out at about seventy dollars a screen, and a stated ceiling of twelve is six times what anything else on this shelf supports — for a small block, or a house that wants a monitor on every floor, nothing here competes. Two things the price does not cover: the RVV-4 interconnect cable, which AMOCAM tells you to buy separately, and any recording. The camera is 700TVL analog, not 1080p.
No screen resolution. No recording. No release contact rating.
Which is the only real answer to this shelf’s multi-monitor question.
Six monitors ship. Twelve are supported.
The seven-hundred-dollar single-door set on this shelf caps at two stations. The two-wire systems ship two.
Six screens at four hundred and twenty-five dollars is about seventy dollars each.
Which AMOCAM says outright, and names the listing for.
RVV-4 wire for the indoor-to-outdoor connection is a separate purchase.
Six monitors means a run to each apartment, so the quantity is substantial.
This shelf’s buying tip is about counting conductors before ordering. Here you count meters as well.
Which is an older measuring system, and worth translating.
TVL counts horizontal analog lines. Seven hundred is a good analog CCTV camera, roughly equivalent to a little under a megapixel.
The 1080p cameras on this shelf are digital and about two megapixels.
On a 7-inch screen, 700TVL is a usable, slightly soft color picture that identifies a caller. For a six-household entrance panel, that is the job.
On a system for six households.
The screens are buttons rather than touch, which on a shared entrance is arguably the more durable choice.
Nothing is stored. Six families, one camera, no card — and unlike the two single-door AMOCAM kits here, this listing carries no warning about what the unlock output will and will not drive.
On sale at around $425 on the American Amazon store at the time of checking.

| Dwellings | One outdoor camera and six indoor monitors, stated to support one building of six households — each monitor answering, monitoring and unlocking |
|---|---|
| Expansion | Stated support for a maximum of twelve monitors. That is the highest figure on this shelf by a wide margin: the seven-hundred-dollar single-door set here caps at two stations, and the two-wire systems ship two |
| Monitors | Six 7-inch LCD press-key screens, with door answering, monitoring, unlocking, two-way intercom and a mute function — stated. Press-key rather than touch |
| Camera | A 700TVL CMOS night-vision camera, stated. TVL is an analog television-line count rather than a pixel figure: 700 lines is a competent legacy CCTV camera and is not comparable to the 1080p claims on this shelf |
| Wiring | Wired, and the interconnect cable is NOT included: AMOCAM states that if you need RVV-4 wire for the indoor-to-outdoor connection you should search a separate listing, and names it. Four conductors, and a purchase the price does not cover |
| Resolution | Not published for the screens. The 700TVL figure belongs to the camera |
| Monitor | Sixteen chimes with adjustable volume, brightness and contrast — stated, as on the rest of the AMOCAM range here |
| Access control | Unlock from each monitor, stated. No contact type, voltage or current rating appears, and no warning about strike or magnetic locks on this listing, unlike the two single-door AMOCAM kits on this shelf |
| Recording | None. No card slot and no capture |

That you are reading two different measuring systems, and that it is older. TVL is television lines — an analog measure of horizontal resolution, where 700 lines is roughly equivalent to a little under a megapixel and represents a good analog CCTV camera. The 1080p cameras on this shelf are digital and about two megapixels. In practice: 700TVL on a 7-inch screen is a usable, slightly soft color picture that identifies a caller, and it is not comparable to the sharpness of a 1080p feed. For a six-household entrance panel that identifies visitors, it is sufficient.
Unknown from this page, and that is the one thing to settle before ordering. AMOCAM states that RVV-4 wire for the indoor-to-outdoor connection is a separate purchase and names the listing to find it on — which is honest, and it means the four hundred and twenty-five dollars is not the whole price. A six-monitor installation needs a run to each apartment, so the cable quantity is substantial. This shelf's buying tip is about counting conductors before ordering; here you also have to count meters.
It is the stated maximum and it is the largest figure anyone on this shelf publishes, so it is the only product here that answers the introduction's multi-monitor question at any scale. Six ship in the box. What the listing does not say is how the additional six are powered, whether a bus or a distributor is needed, or whether a second outdoor panel can be added — and at twelve monitors on one camera the practical questions are about the cable topology rather than the electronics. Ask AMOCAM for the wiring diagram before planning a twelve-apartment install.

| Model | Price | Monitors | Wiring | Resolution | Access control |
|---|---|---|---|---|---|
| AMOCAM V70C-520-6 apartment video intercom, 6 households | $425 | Six 7-inch LCD press-key screens, with door answering, monitoring, unlocking, two-way intercom and a mute function — stated. Press-key rather than touch | Wired, and the interconnect cable is NOT included: AMOCAM states that if you need RVV-4 wire for the indoor-to-outdoor connection you should search a separate listing, and names it. Four conductors, and a purchase the price does not cover | Not published for the screens. The 700TVL figure belongs to the camera | Unlock from each monitor, stated. No contact type, voltage or current rating appears, and no warning about strike or magnetic locks on this listing, unlike the two single-door AMOCAM kits on this shelf |
| LUMOBELL LMIP7_08C_2F two-wire two-family video intercom with 7-inch touch screens | $250 | One 7-inch touch screen per household. Whether a third can be added is not stated | Two-wire, stated to use existing doorbell wiring. This shelf's introduction makes this the installation detail that decides the job, and on a converted house with one original bell cable to the street it is the only workable route | The 1080p figure is the camera's. No screen resolution is published for either 7-inch monitor | Door or gate release from the Tuya app, RFID keycards or the indoor displays — stated, with tenants and landlords both named. No contact type, voltage or current rating appears |
| LUMOBELL 2W_KW02_IP7 two-wire video intercom with dual 7-inch touch screens | $210 | Two 7-inch touch screens, with two-way calling between rooms as well as to the door — stated. Room-to-room calling is a genuine intercom function that only this listing and its two-family sibling claim | Two-wire, stated to use existing lines. This shelf's introduction calls this the installation detail that decides the job: a two-wire system reuses an existing bell cable and a four-wire one usually does not. Three listings on this shelf need four conductors | The 1080p figure is the camera's. NO SCREEN RESOLUTION IS PUBLISHED, so what the 7-inch touch panel actually displays is unknown — a 1080p feed on an 800 × 480 panel looks like 800 × 480 | Door release from the monitors, the Tuya app or RFID tags — stated. No contact type, voltage or current rating appears, which this shelf's introduction asks for specifically |
| AMOCAM 70H-M42 wired video door phone system, 7-inch touch screen, two monitors | $156 | Two 7-inch color LCD touch screens with one outdoor camera, stated in the description. Touch rather than the button operation on the single-monitor version of this same system | A four-wire setup, surface mounted, with a rain cover, connection terminals and screws supplied — stated. This shelf's introduction warns that a four-wire system usually cannot reuse an existing bell cable, so count the conductors to the gate before ordering | Not published. The single-monitor version of this same system states 800 × 480; this listing states a touch screen and no pixel count | Electric lock control from the monitor — and the listing states the limit plainly: an electric bolt lock, electric strike or electromagnetic lock needs an extra power supply controller between the intercom and the lock. It is one of only two listings on this shelf to admit this, and no contact rating is given |
