Viking K-1275-IP VoIP Entry Phone Prox Card Reader & Video

Viking Electronics K-1275-IP Vandal-Resistant VoIP Entry Phone with Proximity Reader, Video Camera & 12-Button Auto Dialer

The Viking Electronics K-1275-IP is a purpose-built SIP 2.0 VoIP entry phone system designed for multi-tenant residential and commercial access points where you need telephone directory dialing, proximity card access, and analog video monitoring in a single hardened unit. Built from 14-gauge louvered 316 stainless steel, the K-1275-IP handles everything from apartment lobbies to secure facility entrances — delivering audio entry, card-based door release, and composite video to a connected recorder or monitor, all over a single PoE network connection. If you're shopping for a VoIP entry phone that consolidates access control, intercom, and video into one device without requiring a separate power supply, this is the unit to evaluate.

Key Features

• SIP 2.0 over PoE Class 2 (802.3af, <6.5W): The K-1275-IP draws under 6.5 watts from any standard 802.3af PoE switch port — no dedicated power run, no transformer, no outlet near the door. It registers as a standard SIP endpoint, so it integrates with virtually any IP PBX or hosted VoIP platform without proprietary gateways.
• 12-Button Auto Dialer with Built-In Directory: Tenants or visitors select from a pre-programmed directory and the unit dials the corresponding SIP extension or PSTN number directly. For apartment buildings or multi-suite offices, this eliminates the need for a separate directory system wired to a separate entry device.
• 125KHz Proximity Card Reader (26-Bit Wiegand, up to 2.0″ read range): The integrated reader operates at 125KHz and outputs standard 26-bit Wiegand — compatible with the vast majority of commercial access control panels. Read range of 1.25″ to 2.0″ is appropriate for controlled-presentation enrollment; the 500 ft maximum cable run to the access control panel gives real flexibility in head-end placement.
• Dual SPDT Relay Contacts (2 Amp each): Two independent relay outputs let you drive a door strike on one relay and a secondary device (gate, turnstile, or alarm shunt) on the other without adding an external relay board. Each contact is rated 2 Amp — sufficient for most electric strikes and magnetic locks when paired with appropriate power.
• Built-In Analog Video Camera — 420-Line CMOS, 80° Horizontal FOV, 2.1mm Pinhole Lens: The 1/4″ color CMOS sensor captures composite NTSC video at 640×480 @ 30fps and outputs 1 Vp-p over 75-ohm coax. The 2.1mm conical pinhole lens delivers an 80° horizontal / 60° vertical / 100° diagonal field of view — wide enough to frame the approach zone in front of a standard entry door. The camera tilt adjusts ±20° vertically and ±30° horizontally so you can aim it post-installation without opening the enclosure. At 0.025 lux sensitivity (50 IRE, F1.2), it retains usable color video in dim vestibule lighting. Maximum wire run is 1,000 ft on RG59 or RG6 to a DVR or monitor.
• G.711u/a and G.722 Audio Codecs: G.722 wideband audio (HD voice) delivers noticeably clearer two-way communication compared to narrowband G.711 — important for intelligibility at noisy exterior entrances where a visitor may be competing with traffic or wind noise. G.711u/a fallback ensures compatibility with legacy SIP infrastructure.
• 316 Stainless Steel, 14-Gauge Louvered Faceplate — Permanent Weatherproofing: The 316 grade stainless resists corrosion in coastal and high-humidity environments where 304 grade faceplate hardware typically pits within a few seasons. The louvered design sheds standing water away from the speaker and keypad without additional covers.
• Operating Temperature: -34°C to 60°C (-30°F to 140°F): This range covers unheated exterior vestibules in cold-climate regions without supplemental heating. The EWP variant extends humidity tolerance to 100% for fully exposed outdoor installations.
• Compact Footprint — 5″ × 10″ × 2.5″ overall, 4.5″ × 9.12″ rough-in box: The rough-in box dimensions fit within a standard single-gang deep box rough opening with minor drywall or masonry modification. At 4.4 lbs shipping weight, a single-person installation is practical.
• Regulatory Compliance — FCC Part 15, CE, ICES-003 Class A: FCC Part 15 and CE marks confirm the unit ships ready for North American and European deployments without additional emissions testing or waivers.

Integration & Compatibility

The K-1275-IP registers as a standard SIP 2.0 (RFC 3261) endpoint over 100BASE-TX Ethernet. It will integrate with any SIP-compatible IP PBX (on-premise or hosted), including Asterisk, FreePBX, 3CX, and most enterprise UC platforms. The 26-bit Wiegand proximity reader output is the industry-standard format and connects directly to the card reader port of virtually all commercial access control panels without adapters.

The composite analog video output feeds any DVR, NVR with analog inputs, or standalone monitor that accepts NTSC composite — it is not an IP camera stream. If your recorder only accepts IP camera streams, you will need an analog-to-IP video encoder for the camera output. Plan the coax run separately from the Ethernet run; both are required for full functionality.

For deployments requiring enhanced moisture protection, the K-1275-IP-EWP variant is rated for 100% humidity and is the correct choice for exposed outdoor canopy installations or environments subject to direct water spray. The standard K-1275-IP is rated 5%–95% non-condensing humidity. See the full Viking Electronics product line for companion devices including door controllers and analog entry phones.

Proximity card reader cabling extends up to 500 ft to the access control head-end. The Wiegand output pairs with standard commercial door controllers for credential-based entry independent of the SIP call path — cardholders can unlock the door without initiating a call. Review your VoIP entry phone selection guide for wiring, SIP trunk, and relay sizing considerations before finalizing the installation design.

Frequently Asked Questions

Q: Does the K-1275-IP work with hosted VoIP platforms like RingCentral or 8x8?

A: The K-1275-IP implements SIP 2.0 (RFC 3261) and registers as a standard SIP endpoint. Most hosted VoIP platforms support third-party SIP devices; compatibility depends on whether the platform allows external SIP registration. Confirm with your hosted VoIP provider that they support third-party SIP device registration before purchasing.

Q: Is the built-in camera an IP camera or analog?

A: Analog only. The camera outputs 1 Vp-p composite NTSC video over 75-ohm coax (RG59 or RG6) at 640×480 @ 30fps. It is not an IP camera and does not stream over the Ethernet connection. You will need a separate coax run to a DVR, analog monitor, or analog-to-IP encoder to view or record the video.

Q: What proximity card format does the K-1275-IP support?

A: The integrated reader operates at 125KHz and outputs 26-bit Wiegand — the most common commercial access control format. It is compatible with standard HID, AWID, and other 125KHz proximity credentials. Read range is 1.25″ to 2.0″.

Q: Does the K-1275-IP require a separate power supply?

A: No. The unit is powered by PoE Class 2 (IEEE 802.3af) and draws under 6.5 watts. Any standard 802.3af-capable switch port or midspan injector powers the unit. No separate transformer or AC outlet is required at the door.

Q: What is the difference between the K-1275-IP and the K-1275-IP-EWP?

A: The EWP (Enhanced Weather Protection) variant is rated for humidity up to 100% and is designed for fully exposed outdoor installations subject to direct rain or spray. The standard K-1275-IP is rated for 5%–95% non-condensing humidity — suitable for covered vestibules and interior-facing entries. The EWP ships at 4.6 lbs vs. 4.4 lbs for the standard unit.

Q: What is the maximum cable run for the proximity card reader?

A: The Wiegand output supports cable runs up to 500 ft to the access control panel. The analog video camera supports up to 1,000 ft on RG59 or RG6 coax.

The K-1275-IP earns its place in multi-tenant entry deployments by doing something most entry phones can't: consolidating SIP calling, 26-bit Wiegand card access, and 640×480 analog video into a single 14-gauge 316 stainless enclosure powered by a single PoE drop. That sub-6.5W Class 2 draw means any 802.3af switch port in your IDF cabinet can power it — no electrician, no outlet, no transformer at the door frame.

Technical Highlights:

• G.722 Wideband Audio: At noisy exterior entries — loading docks, parking garage booths, outdoor lobbies — G.722's higher audio bandwidth makes a measurable difference in call intelligibility vs. narrowband G.711. The K-1275-IP supports both, so you get wideband where the SIP platform supports it and automatic fallback where it doesn't.
• 2.1mm Pinhole Lens, 100° Diagonal FOV: The wide diagonal covers the full approach zone in front of a standard door without requiring a separate camera. The ±20° vertical / ±30° horizontal physical adjustment means you can aim it at installation time without dismounting the faceplate — a genuine time-saver on retrofit installations where the rough-in box position is fixed.
• 500 ft Wiegand Cable Run: The reader-to-panel cable can run up to 500 ft, which in a mid-rise residential building typically means the access controller can live in a ground-floor IDF rather than a closet on every floor. Combine with the 1,000 ft analog video run capability and you have real flexibility in head-end architecture.

Deployment Considerations:

• The analog camera output requires a dedicated coax run (RG59 or RG6) separate from the Ethernet/PoE cable. Budget for both runs in your cable schedule — it is a common oversight that surfaces during rough-in when only Cat6 was pulled.
• The standard K-1275-IP is rated 5%–95% non-condensing humidity. If the installation is fully exposed to rain, wind-driven moisture, or high-humidity outdoor environments, specify the K-1275-IP-EWP at rough-in — retrofitting to EWP after the box is set in masonry or drywall is a significant rework.

For apartment buildings, mixed-use properties, and secure office entries where a single door position needs directory dialing, card-based access, and video evidence in one stainless vandal-resistant package — with no dedicated power circuit — the K-1275-IP is the right unit to put in the gang box.
