A screen inside the house works when the phone is upstairs on charge · review
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.
The conclusion Seven hundred dollars buys the best-built door station on this shelf — die-cast aluminum, vandal resistant, LED illumination, a backlit nameplate — and the one figure nobody else publishes: how far the cable can run, 165 feet on 22AWG and 330 on 18AWG. For a gate at the end of a drive that figure is the whole purchase. Two things to check first: the ceiling is two stations, and the page names JV parts in its bullets and JO parts in its description.
No screen resolution. No camera angle. No door-release contact rating.
JV in the bullets. JO in the description.
JV-DV, JV-1MD, PS-2420UL above. JO-DV, JO-1MD, PS-1820UL below.
Two different Aiphone lines, and two different transformers — twenty-four volts against eighteen.
The reference JVS-1V and the bullet detail agree with each other, so JV is the consistent reading. Confirm it with the seller: the power supply is not interchangeable.
The only distance on this shelf.
Twenty-two gauge: 165 ft. Eighteen gauge: 330 ft.
This shelf’s buying tip is about the conductors. Distance is the other half of the same question, and it decides whether a gate at the end of a drive is reachable.
No other maker here publishes one. With any of them, a long run is a gamble.
Which is where the money goes.
Die-cast aluminum, weather and vandal resistant, with LED illumination that comes on in low light and a backlit nameplate.
The cheaper stations on this shelf are an aluminum and acrylic front on a plastic body, with infrared and no lit nameplate.
On a dark gate post, a backlit nameplate is the difference between a caller pressing your button and pressing next door’s.
Which is hard to defend at this price.
One optional JV-1FD, and that is all. A 1×2 system.
The apartment system on this shelf ships six monitors and states twelve, for four hundred dollars less.
For one entrance, the door station justifies it. For a monitor on three floors, it does not.
On sale at around $700 on the American Amazon store at the time of checking.

| Wiring | 24 V DC from the included power supply, with runs up to 165 ft on 22AWG or 330 ft on 18AWG between the door and master stations — stated. It is the only cable run length published on this shelf, and it is the figure this shelf's buying tip is really about |
|---|---|
| Outdoor unit | A die-cast aluminum JV-DV surface-mount door station, stated weather and vandal resistant, with a fixed camera, automatic low-light LED illumination, and a backlit call button and nameplate. Die-cast aluminum rather than the aluminum-and-acrylic panels used elsewhere on this shelf |
| Monitor | A 7-inch JV-1MD master station with hands-free or push-to-talk operation and door monitoring. No screen resolution is published, which it shares with three other listings here |
| Recording | Up to 30 still images stored from calls in the master station — stated. No card slot and no video: it is a call log with pictures, not a recorder |
| Expansion | One optional JV-1FD expansion station, making a 1×2 system — stated, and that is the ceiling. The apartment system on this shelf supports twelve monitors for four hundred dollars less |
| Access control | Activates a connected door release from the master station — stated, with no contact type, voltage or current rating. The release device is not included |
| Supplied | A JV-DV door station, a JV-1MD master station and a PS-2420UL power supply — stated in the bullets. The description on the same page instead lists a JO-DV door station, a JO-1MD master station and a PS-1820UL power supply, which is a different Aiphone series and a different transformer |
| Camera | Fixed, with automatic low-light LED illumination — stated. No field of view angle and no resolution appears, where four listings on this shelf publish an angle |
| Amazon reference | B00JHBTV2G |
| EAN | 0053926347537 |
The page says both, and that needs resolving before you order. The title and every bullet name the JV series — a JV-DV door station, a JV-1MD master station and a PS-2420UL power supply — while the description underneath describes a JO-series box set with a JO-DV station, a JO-1MD master and a PS-1820UL supply. Those are two different Aiphone lines with two different transformers, 24 V versus 18 V. The reference JVS-1V and the bullet detail agree with each other, so the JV reading is the consistent one; confirm it with the seller, because the power supply is not interchangeable.
Because it is the one thing on this shelf that tells you whether an installation is possible. This shelf's buying tip says identifying the conductors before ordering is the difference between an afternoon and a different project entirely, and distance is the other half of that: 165 feet on 22AWG and 330 feet on 18AWG tells you a gate at the end of a drive is within reach on the heavier gauge and not on the lighter. No other maker here publishes a distance at all, so with any of them a long run is a gamble.
That is the stated ceiling, and it is the hardest thing to defend about this set. One optional JV-1FD makes it a 1×2 system and there is no more. The apartment system on this shelf runs six monitors as supplied and states support for twelve, for four hundred dollars less. What seven hundred dollars buys instead is the door station — die-cast aluminum, vandal resistant, backlit nameplate, LED illumination — plus the distance figure and a manufacturer whose parts are still available a decade on. For a single entrance that is a real argument; for a house that wants a monitor on three floors it is not.
Between security devices of the same category and nearby price. Shown: what they all state. A half-filled column says nothing.
| Model | Price | Wiring | Recording | Access control | Camera |
|---|---|---|---|---|---|
| Aiphone JVS-1V JV Series 1×1 wired video intercom box set, 7-inch monitor | $700 | 24 V DC from the included power supply, with runs up to 165 ft on 22AWG or 330 ft on 18AWG between the door and master stations — stated. It is the only cable run length published on this shelf, and it is the figure this shelf's buying tip is really about | Up to 30 still images stored from calls in the master station — stated. No card slot and no video: it is a call log with pictures, not a recorder | Activates a connected door release from the master station — stated, with no contact type, voltage or current rating. The release device is not included | Fixed, with automatic low-light LED illumination — stated. No field of view angle and no resolution appears, where four listings on this shelf publish an angle |
| AMOCAM V70C-520-6 apartment video intercom, 6 households | $425 | 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 | None. No card slot and no capture | 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 | 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 |
| LUMOBELL LMIP7_08C_2F two-wire two-family video intercom with 7-inch touch screens | $250 | 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 | Photos and videos to an included SD card, with no subscription — stated, and stated to save both families the monthly cost. The card capacity is not given, and the listing does not say whether the two households share one card or have separate storage | 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 | 1080p with a 140-degree wide angle, infrared night vision and human detection — stated. Human detection rather than motion alone is what stops a two-household panel notifying four phones every time a cat crosses |
| 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 | 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 | 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 | 1080p with a 140-degree wide angle and infrared night vision, stated. A hundred and forty degrees is the widest on this shelf, against ninety-two on the AMOCAM stations |
