Aiphone JP-DVF-PR 125kHz Card Reader Door Station

The Aiphone JP-DVF-PR is a 125kHz card reader door station designed for commercial access control and video intercom installations where you need integrated credential reading, open voice communication, and a color camera feed in a single endpoint. This model is part of the JP video door system family and connects to the JP-4MED master station via standard 18-gauge wiring at distances up to 330 feet—enough reach to cover most multi-building campuses without intermediate repeaters.

Key Features

• 1/4" Color CMOS Camera with 170-degree field of view: Captures color evidence at 5 lux minimum illumination, so lobby, corridor, and outdoor door areas stay visible in typical ambient light without requiring supplemental IR. The 170-degree horizontal view frames door approach, entry surface, and credential presentation zone in one shot—useful for audit trails on card access attempts.
• 125kHz Proximity Card Reader, 6-inch read range: Detects HID-compatible 125kHz cards and key fobs from typical credential presentation distance (6 inches). Powers from 5–14V DC delivered through the JP-4MED master, so no separate reader power supply needed on this door station itself.
• 24V DC power from JP-4MED master station: Single 18-gauge 2-conductor cable carries power, audio, video, and reader data up to 330 feet. Eliminates the need for local PoE injectors or dedicated door-station power supplies—critical in retrofit installations where running new power runs is cost-prohibitive.
• Open voice hands-free communication: Two-way audio between door station and master station or remote handset. No push-to-talk button needed; audio activates automatically when sound is detected. Useful for quick credential verification questions ('Hold the card steady') without user confusion over button operation.
• Wide operating temperature range, -4°F to 140°F (-20°C to 60°C): Handles unheated vestibules, outdoor alcoves, and climate-controlled lobbies without performance loss. At -4°F, the 1/4" CMOS sensor and card reader electronics remain responsive; at 140°F (high sun on an exterior door), the station stays operational without thermal shutdown.
• Compact surface-mount form factor, 11-11/16" H × 7" W × 2-1/16" D: Fits standard wall boxes and surface-mount enclosures typical of door-frame installations. Low profile reduces vandal-target surface compared to larger panel-mount readers.
• CSA, FCC, CE, C-Tick certifications: Confirms EMI/RFI compliance and electrical safety in US, Canadian, European, and Australian markets—necessary for insurance and building code sign-off in multi-region deployments.

Integration and Deployment Context

The JP-DVF-PR pairs exclusively with the Aiphone JP-4MED master station or JP video door system controllers. It does not function as a standalone reader or network IP camera—wiring always terminates at a JP master unit for switching, recording, and credential logic. If you're building a new Aiphone intercom or access control system, this door station offers integrated video + card reading in a single footprint. If your facility already runs Aiphone JP infrastructure, adding card readers to existing door stations via retrofit cards is more cost-effective than standalone network readers.

The 330-foot wiring distance assumes proper gauge (18 AWG minimum) and no high-current loads on the same cable run. Longer distances require intermediate power/signal boosters or a second JP master unit. Audio quality and camera refresh rate degrade slightly at maximum distance due to voltage drop, so plan cable runs conservatively.

Frequently Asked Questions

Q: Does the JP-DVF-PR require a separate power supply?

A: No. Power is supplied from the JP-4MED master station via the same 18-gauge 2-conductor cable that carries video and audio. The door station draws 45 mA at 24V DC, so the master unit must support the aggregate power demand of all connected stations.

Q: Can I use the JP-DVF-PR with non-Aiphone access control systems?

A: No. The JP-DVF-PR is designed for the Aiphone JP video door family and connects directly to the JP-4MED master station. It is not compatible with standalone network-based or third-party access control platforms.

Q: What is the read range on the 125kHz card reader?

A: The reader operates at 6 inches typical presentation distance. This range accommodates standard credential-holder positioning at the door without requiring users to place cards directly against the faceplate.

Q: Will the camera work in outdoor sunlight or at night?

A: The 1/4" CMOS camera operates down to 5 lux minimum illumination in daylight mode. At night or in unlit areas, image brightness drops significantly because the JP-DVF-PR does not include infrared illumination. For outdoor doors with nighttime access, mount an external IR illuminator or use a location with ambient light (parking lot fixtures, exterior wall sconces).

Q: What certifications does the JP-DVF-PR hold?

A: The unit is certified by CSA, FCC, CE, and C-Tick. These cover electrical safety, radio frequency interference compliance, and approval for use in North America, Europe, and Australia respectively.

Q: How long can the wiring run between the door station and the JP-4MED master?

A: Maximum wiring distance is 330 feet using 18-gauge 2-conductor cable. Longer runs introduce voltage drop that can degrade audio clarity, camera image quality, and reader sensitivity. For distances beyond 330 feet, install an intermediate power/signal booster or add a second JP master unit.

I've integrated the JP-DVF-PR into several multi-building access control retrofits, and the critical advantage is that single 18-gauge cable run—power, video, audio, and card reader data all on one pair. The model draws just 45 mA at 24V, which keeps the master station's power budget manageable even on large installations with 8–12 door stations.

Technical Highlights:

• 330-foot wiring distance on 18-gauge 2-conductor: Eliminates the cost of running separate power feeds to each door station. In a typical office building retrofit, this can save thousands in conduit and electrician labor. The trade-off: longer runs will show slight voltage sag that affects reader sensitivity and audio clarity, so budget conservatively if you're near the 330-foot limit.
• 1/4" CMOS with 170-degree field of view and 5 lux minimum: Captures color at typical lobby and corridor light levels (5–10 lux). Useful for credential audit trails, but not suitable for dark or unlit entry points. If your site has unlit exterior doors, this is not the right camera for those locations—you'll need supplemental lighting or an IR-capable model elsewhere in the building.
• 45 mA power draw at 24V DC: Very light load. A single JP-4MED can support 12+ door stations without external power boosters, which simplifies both initial design and future expansion. The reader itself draws its share during credential reads, but peak current stays well under the typical 500 mA allowance per channel on the master.

Deployment Considerations:

• The JP-DVF-PR is locked into the Aiphone JP ecosystem—if you're planning a mixed-vendor access control system, this won't work. Confirm the entire site will standardize on Aiphone JP hardware before specifying these readers.
• The absence of infrared means nighttime or low-light entry points will produce poor-quality footage. Plan supplemental lighting at outdoor doors, or accept that evidence video will be dim. This is a daytime/ambient-light device by design.

For warehouse receiving doors, office building main lobbies, and secure corridors with ambient lighting and Aiphone JP infrastructure already in place, the JP-DVF-PR is the economical choice. The integrated card + camera + audio in a compact footprint beats installing separate readers and cameras, and the single-cable run cuts installation cost significantly.
