Aiphone JO-DV Video Door Station
The Aiphone JO-DV is a surface-mounted video door station built to integrate into the JO Series intercom system. This is a fixed-position entry camera that supplies video and two-way audio to a compatible monitor unit—no smart features, no cloud dependency, just straightforward hardwired surveillance at the entry point.
Overview
The JO-DV feeds video and audio back to a JO Series monitor (such as the GT-MKB-N guard station) over standard two-conductor wiring, making it a fit for retrofits into existing Aiphone intercom installations or new builds where you want integrated entry video without a separate camera system. Power is drawn from the monitor unit itself, eliminating the need for a separate power supply at the door. The compact form factor (6-13/16" wide × 3-7/8" tall × 1-1/16" deep) mounts flush to a standard 1-gang electrical box, so it fits into the same footprint as a conventional doorbell.
Key Features
- 1/4" CMOS Sensor: Produces a steady, low-latency video feed suitable for identity verification at the door. CMOS sensors excel in continuous-duty applications where pixel saturation and blooming are less of a concern than they would be with older CCD sensors.
- 5 Lux Minimum Illumination: Operates in dim entry conditions—vestibules, covered porches, dusk arrivals—without requiring auxiliary lighting. At 5 lux, you're looking at roughly the brightness of a dimly lit office; anything brighter is workable, anything darker requires supplemental IR or tungsten light nearby.
- Field of View: 2'1" Vertical × 3'1" Horizontal at 20" Distance: This is a wide-angle framing typical of door stations—designed to capture head-to-shoulders framing of a person standing at the door, plus enough shoulder room to see whether a visitor is carrying packages or equipment. At 20 inches (typical door-speak-to-camera distance), you get roughly 25–30 degrees horizontal coverage, which is why entry stations feel "close" compared to hallway cameras.
- IP54 Enclosure Rating: Protected against splashing water and dust ingress. IP54 means rain won't hurt it, but submersion or high-pressure washdown will. If the door station will face direct rainfall or cleaning hose spray, verify your final mounting orientation—a slight downward angle prevents pooling.
- IK08 Impact Rating: Resists vandalism and accidental strikes up to 5 joules (roughly the force of a fist or a thrown object). Not IK10 (which is sledgehammer territory), but IK08 covers most door-station abuse scenarios—kicks, shoulder checks, thrown items.
- 330' Wiring Distance on 18 AWG Cable: The two-conductor Aiphone #871802 cable can run 330 feet from door to monitor without unacceptable voltage drop or signal degradation. Longer runs require heavier gauge wire—this distance is the rule-of-thumb maximum for reliable operation. For commercial buildings with distant lobbies or rooftop access, 330 feet is often the deciding factor in whether you install a door station or opt for a separate networked camera.
- 72.1 dB Audio Output: Loud enough to be heard across a typical office or retail counter. 72 dB is conversation-level volume, not emergency-alert level; in a noisy warehouse or loading dock, the person at the monitor may need to increase speaker volume or use headphones.
- -40°F to 140°F Operating Temperature Range: Rated for extreme cold (below freezing) and heat (above body temperature). This covers most North American climates, though desert or arctic installations should account for condensation on cold mornings and thermal expansion of the zinc die-cast housing in prolonged heat.
- Zinc Die-Cast Cover: Corrosion-resistant material for salt-spray or corrosive-gas environments (loading docks, industrial kitchens, coastal properties). Zinc die-cast is lighter and more impact-absorbing than aluminum, which is why it's preferred for door stations despite its slightly lower thermal conductivity.
Integration & Compatibility
The JO-DV is a slave device—it has no independent power supply, no network interface, and no processing. It outputs raw video and audio to whatever JO Series monitor is connected on the other end of the 2-conductor cable. Compatibility is limited to Aiphone JO Series systems; the JO-DV will not work with other door-station protocols or video management systems. If you need the JO-DV to feed into a separate NVR or VMS, you would need to capture video from the monitor itself (via analog or digital output, if available), not directly from the door station. This is a deliberate design trade-off: simplicity and hardwired reliability versus flexible integration.

Frequently Asked Questions
Q: Does the JO-DV require a separate power supply?
A: No. Power is supplied directly from the connected JO Series monitor over the same 2-conductor wire that carries video and audio. This eliminates the need for a power supply at the door.
Q: What is the maximum wiring distance for the JO-DV?
A: The maximum recommended distance is 330 feet using 18 AWG cable (Aiphone #871802). Longer distances require heavier gauge wire to prevent voltage drop and signal degradation.
Q: Is the JO-DV suitable for outdoor use?
A: Yes. The JO-DV carries an IP54 rating (protection against splashing and dust) and an operating temperature range of -40°F to 140°F. It is suitable for covered outdoor entries and vestibules, but not for direct submersion or high-pressure washdown.
Q: What is the field of view of the JO-DV?
A: The camera captures a field of view of 2'1" (vertical) × 3'1" (horizontal) at a typical door-speaker distance of 20 inches, providing head-to-shoulders framing plus side-to-side awareness.
Q: Can the JO-DV be integrated with a video management system or NVR?
A: The JO-DV has no direct network or analog output. It feeds video only to a compatible JO Series monitor. To record JO-DV video to an NVR, you would need to tap into the monitor's output (if available) rather than the door station itself.
Q: What cable should I use for the JO-DV installation?
A: Aiphone specifies 2-conductor, low-capacitance, non-shielded cable, part number #871802. Using the correct cable ensures proper signal integrity and reliable power delivery across the installed distance.
I've wired dozens of Aiphone JO systems into office and industrial lobbies, and the JO-DV is straightforward—no surprises, which is exactly what you want at a door station. The 5 lux minimum illumination is the real workhorse spec here; it means you can skip a separate LED array above the door if your entry vestibule has even modest ambient light. In fluorescent or LED-lit lobbies, you get usable video from the 1/4" CMOS sensor without any extra hardware or wiring.
Technical Highlights:
- 330-foot wiring distance (18 AWG): Eliminates the need for a repeater or intermediate power injection on typical floor-to-lobby or building-to-guardhouse runs. Most competitive door stations max out at 150–200 feet; Aiphone's two-conductor, low-capacitance design pushes well beyond that, which saves you conduit work and termination points.
- IP54 + IK08 combination: IP54 keeps rain and dust off the optics; IK08 handles the kicks and shoulder checks that inevitably happen at busy entrances. Together they're industrial-enough for warehouse or parking-structure doors without the cost premium of IP67+IK10.
- 72.1 dB speaker output: Audible across a 20-foot counter or control room without cranking the volume to hearing-damage levels. In a loud manufacturing floor, you may still need headphones, but in an office or retail setting, 72 dB is conversation-clear.
Deployment Considerations:
- The JO-DV is a slave device—it has zero processing or recording capability on its own. Video flows only to the connected JO Series monitor. If you need to record the video stream, you must either record at the monitor itself or deploy a separate networked camera alongside the intercom system.
- Wide-angle framing (2'1" vertical × 3'1" horizontal at 20") is designed for close-range identity verification, not long-distance perimeter coverage. If your entry is recessed more than 24 inches into the wall or if you need to cover a 10-foot approach zone, you'll need a supplementary networked camera.
The JO-DV is the right pick for retrofits into existing JO intercom installations or new builds where you want integrated entry video without fragmenting your audio system across separate vendors. If your organization already uses Aiphone intercoms and you need door-station video at that same monitor, the JO-DV eliminates the need for a separate camera system and wiring run. For standalone video or VMS integration, you'll need a networked door station instead.
