A screen inside the house works when the phone is upstairs on charge · review
The cheapest video intercom here at eighty-two dollars, and the only one that says how many pixels its screen has.
The conclusion Eighty-two dollars for a 7-inch video intercom with the rain cover, terminals and screws in the box, and the only screen resolution anybody on this shelf publishes — 800 × 480, about 131 pixels per inch, which recognizes a face and will not read a label. It also states that its release output will not drive a strike, bolt or magnetic lock without an added controller. Four conductors required, one monitor, no recording.
No recording. No contact rating.
Eight hundred by four hundred and eighty.
Across seven inches that is about a hundred and thirty-one pixels per inch.
You will recognize a face, read a uniform logo and see a parcel. You will not read the address on it.
Two listings here claim 1080p. Both figures belong to their cameras, and neither says what its panel displays. Seven-inch intercom panels are commonly 800 × 480, so read this as the likely figure elsewhere too.
Which is the cheapest way onto this shelf.
This shelf’s buying tip decides whether you can take it: an existing two-core cable is an afternoon, four cores through a buried duct is a different project.
If the duct already has four cores, this is the whole system for eighty-two dollars — rain cover, terminals and screws included.
Which is one place to answer.
An apartment or a bungalow, fine. A house with the kitchen at the back and the bedroom upstairs, not.
The same system with two touch monitors is a hundred and fifty-six. Seventy-four dollars for a second screen, against two-monitor systems that start at two hundred and ten here.
Stated, which is a favor.
Only an electronic lock opens directly from the monitor. A strike, a bolt or a magnetic lock needs a power supply control added in between.
That is a board and a transformer, and no contact rating is published to size them against.
On sale at around $82 on the American Amazon store at the time of checking.

| Resolution | 800 × 480 on a 7-inch LCD — stated, and the only screen resolution published on this shelf. Across seven inches that is about 131 pixels per inch: enough to recognize a face at the door, not enough to read a delivery label |
|---|---|
| Monitors | One 7-inch LCD monitor with button operation and one outdoor camera. The 70H-M42 version of this same system ships two monitors with touch screens for seventy-four dollars more |
| Wiring | A four-wire setup, surface mounted, with a rain cover, connection terminals, screws and materials supplied — stated. This shelf's introduction warns that a four-wire system usually cannot reuse an existing bell cable |
| Access control | Electric lock control from the monitor, with the limit stated: only an electronic lock opens directly from the indoor monitor, and a strike lock, bolt lock or magnetic lock needs a power supply control to work with the system. No contact rating is published |
| Outdoor unit | A 92-degree camera with a color CMOS sensor behind an aluminum alloy and acrylic front panel, stated against vandalism, with weatherproofing and infrared night vision |
| Monitor | Sixteen chimes, adjustable volume, brightness and contrast, hands-free intercom, auto turn off — stated. The indoor monitor is acrylic and ABS with button operation |
| Installation | Three cautions stated: test with the original cable before installing, keep the units apart while testing or they howl, and connect the power adapter to the indoor monitor and never to the outdoor unit, which would burn it out |
| Recording | None. No card slot, no memory and no capture |
| Audio | Hands-free, two-way, stated |

About a hundred and thirty-one pixels per inch, which is legible rather than sharp — you will recognize a face, read a uniform logo and see a parcel, and you will not read the address on it. This is the only screen resolution published on this shelf, which makes it the only honest reference point: the 1080p figures that appear on two other listings here describe their cameras, and neither says what its panel displays. Seven-inch intercom panels are commonly 800 × 480, so take this as the likely figure elsewhere too.
For an apartment or a bungalow, yes. For a house where the kitchen is at the back and the bedroom is upstairs, it means missing callers or running. The same system in its two-monitor form is a hundred and fifty-six dollars and adds a touch screen, which is seventy-four dollars for a second screen — cheaper than the two-monitor systems that start at two hundred and ten here, and more than twice this price. This shelf's introduction lists multi-monitor support as something this shelf compares, and this is the single-monitor end of it.
Only if the lock is an electronic lock in AMOCAM's sense. The listing is specific and it is doing you a favor: only an electronic lock opens directly from the indoor monitor, and a strike lock, bolt lock or magnetic lock needs a power supply control added between the intercom and the lock. That is an extra board and transformer. This shelf's introduction asks whether the monitor can drive a strike and on which contact; here the answer is no, not directly, and no contact rating is given to size a controller against.
Between security devices of the same category and nearby price. Shown: what they all state. A half-filled column says nothing.
| Model | Price | Wiring | Access control | Recording |
|---|---|---|---|---|
| AMOCAM 70H-M4 wired video intercom kit, 7-inch 800 × 480 monitor | $82 | A four-wire setup, surface mounted, with a rain cover, connection terminals, screws and materials supplied — stated. This shelf's introduction warns that a four-wire system usually cannot reuse an existing bell cable | Electric lock control from the monitor, with the limit stated: only an electronic lock opens directly from the indoor monitor, and a strike lock, bolt lock or magnetic lock needs a power supply control to work with the system. No contact rating is published | None. No card slot, no memory and no capture |
| Aiphone LEM-1DLS Access Sentry audio intercom set, 1 door, 1 master station | $150 | Two-conductor with an overall shield, from the door station to the answering station, with Aiphone #822202 (22AWG) or #821802 (18AWG) named by part number. It is the only listing on this shelf to name a cable, and the shield matters: an unshielded run alongside mains cable hums | A normally-open dry contact rated 30 V AC/DC at 1 A — stated. This shelf's introduction makes gate release its second decisive specification and asks specifically on which contact; this is the only listing on this shelf that answers. A dry contact means the intercom closes a circuit and supplies no power, so the strike needs its own supply within that rating | None. No card, no memory and no capture |
| AMOCAM 70H-M42 wired video door phone system, 7-inch touch screen, two monitors | $156 | 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 | 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 | None. No card slot, no memory and no capture |
| LUMOBELL 2W_KW02_IP7 two-wire video intercom with dual 7-inch touch screens | $210 | 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 | 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 | Snapshots or video to an included SD card, with no monthly fee and no cloud — stated. The card capacity is not given. It is one of two listings on this shelf that record to card at all |
