Viking X-35-BK HD Video IP Intercom 1080p SIP Wide-Angle PoE

Viking Electronics X-35-BK IP Entry Phone with HD Video

The Viking Electronics X-35-BK is a SIP-compliant IP video intercom built for demanding access points where you need reliable HD video identification, two-way audio, and door control in a single flush-mount unit. Deploying the X-35-BK means no separate camera, no separate intercom — it handles 1080p video calling, a dedicated NVR stream with audio, and relay-controlled door release all from a standard PoE drop. For integrators spec'ing lobby entries, gate stations, or controlled access corridors, this is a purpose-built endpoint that wires straight into your existing SIP infrastructure.

Key Features

• 1080p SIP Video Calling: H.264 video encoding at up to 1080p delivers evidence-grade caller identification during the call itself — not just a still snapshot. MJPEG is also supported for compatibility with legacy decoders. If your VMS or SIP video client can pull an RTSP stream, you have a real-time HD view of the entry point during every interaction.
• 126° Wide Viewing Angle: At 126 degrees, the built-in camera captures the full width of a standard doorway including both shoulders and any packages on the ground — useful at residential entry points and package delivery bays where partial coverage misses the reason for the visit.
• Separate NVR Stream with Audio: The X-35-BK pushes a dedicated NVR stream alongside the SIP call stream. That means your video management system records continuously independent of whether a call is active — a critical distinction for audit trails and post-incident review on access points.
• PoE Class 1 — Under 4 Watts: Drawing less than 4W via 802.3af PoE, this unit won't stress your switch's power budget even when deployed across a multi-port PoE injector on a small building. No local power supply, no additional wiring — just a single Cat5e/6 run handles both data and power.
• 2-Amp Relay Contacts: The onboard relay supports door strike and magnetic lock control at up to 2A — sufficient for the vast majority of commercial door hardware. You're wiring the intercom and the door release from the same endpoint without an external relay module.
• -40°F to 140°F Operating Range: Rated for -40°C to 60°C, this unit handles harsh winters and sun-exposed wall installations without a heated enclosure. The EWP (Extended Weather Protection) variant supports up to 100% humidity for coastal and high-humidity environments; the standard X-35-BK is rated 5%–95% non-condensing.
• 304 Stainless Steel Faceplate: The BK model uses 14-gauge 304 stainless steel with a durable powder-painted finish in textured black. The camera window is impact-resistant polycarbonate — both materials chosen for outdoor exposure and vandal deterrence at ground-level mounting heights.
• HD Audio Codecs — G.711u, G.711a, G.722: G.722 wideband audio (7kHz bandwidth) makes voice intelligibility noticeably better than standard G.711 narrowband — relevant at noisy loading docks or windy exterior entry points where garbled audio causes repeated call attempts and user frustration.
• 1000BASE-T Network Interface: Gigabit Ethernet means the unit won't bottleneck on a modern switched network even when streaming HD video continuously. This also simplifies cabling — any Cat5e/6 infrastructure already supporting IP cameras handles the X-35-BK without re-runs.
• Flush Mount in Double-Gang Box: The 5″ × 5″ × 2.25″ form factor is designed to flush-mount in a standard double-gang electrical box, keeping the installation clean and low-profile. Surface mount is also supported with an optional VE-Series box — useful for retrofit installs where cutting into the wall isn't practical.
• SIP 2.0 (RFC 3261) Compliance: Native SIP 2.0 means the X-35-BK registers as a standard SIP endpoint on any RFC 3261-compliant PBX or hosted VoIP platform — Cisco, Poly, Grandstream, 3CX, Asterisk, FreePBX. No proprietary gateway or middleware required.

Integration and Compatibility

The X-35-BK integrates directly with Viking Electronics IP intercoms and entry systems and any SIP 2.0 infrastructure following RFC 3261. It operates as a standard SIP endpoint, registering with hosted or on-premises PBX platforms and supporting video calls to SIP video phones or softclients capable of H.264 decoding. The dedicated NVR stream pairs with network video recorders for continuous recording independent of call activity. For multi-door deployments, this unit fits alongside the broader IP intercom product line. Power planning is straightforward — 802.3af Class 1 under 4W integrates with any standard PoE switch without a separate power budget calculation. If you're planning coverage for multiple entry points, review the IP intercom selection guide for SIP trunk sizing and relay wiring considerations.

Frequently Asked Questions

Q: Does the X-35-BK require a separate SIP PBX, or can it call directly to a SIP video phone?

A: The X-35-BK is SIP 2.0 (RFC 3261) compliant and can register with any standard SIP PBX or hosted VoIP platform. It can also be configured for direct SIP peer-to-peer calling to a SIP video phone without a PBX in simpler deployments.

Q: What is the difference between the X-35-BK and the X-35-BK-EWP?

A: The EWP (Extended Weather Protection) variant is rated for up to 100% humidity and uses 316 stainless steel faceplate material. The standard X-35-BK uses 304 stainless steel and is rated for 5%–95% non-condensing humidity. Both share the same -40°F to 140°F operating temperature range. The EWP is the right choice for coastal environments, car washes, or any location with direct water exposure.

Q: Can the X-35-BK stream to a VMS for continuous recording?

A: Yes. The X-35-BK provides a dedicated NVR stream with audio that operates independently from the SIP call stream. Your video management system can record this stream continuously regardless of whether an active call is in progress.

Q: What door hardware can the X-35-BK control directly?

A: The onboard relay contacts are rated at 2 amps, which covers most commercial door strikes and magnetic locks. Verify your specific door hardware current draw against the 2A relay rating before wiring — higher-draw hardware may require an external relay.

Q: Does the X-35-BK flush-mount in a standard electrical box?

A: Yes. At 5″ × 5″ × 2.25″, it is designed to flush-mount in a standard double-gang electrical box. For retrofit installs or locations where wall cutting isn't feasible, an optional VE-Series surface-mount box is available.

Q: What is the power requirement for the X-35-BK?

A: The X-35-BK is powered via IEEE 802.3af PoE, Class 1, drawing under 4 watts. No local power supply or separate power injector is required — a single Cat5e or Cat6 run from a PoE-capable switch handles both data and power.

The X-35-BK stands out in the SIP intercom space primarily because of the dual-stream architecture — you get a SIP video call stream for live operator interaction AND a separate NVR stream with audio for continuous recording, both from a single PoE endpoint drawing under 4 watts. That separation matters operationally: your VMS doesn't lose its recording window just because nobody answered the door call, and your call history doesn't get tangled up with your security recordings.

Technical Highlights:

• Sub-4W PoE Class 1: Running under 4 watts means you can put 12 of these on a 48W PoE budget with headroom — relevant for panel-fed PoE injectors at gate stations or remote building entrances where the switch is powering multiple devices from a single circuit.
• G.722 Wideband Audio: The 7kHz bandwidth of G.722 is a real operational improvement over standard G.711 at high-noise entry points — loading docks, parking garage entries, exterior gates in wind. Fewer repeated call attempts means less operator frustration and faster throughput at high-traffic doors.
• -40°F Cold-Start Rating: The -40°F lower limit means no heated enclosure add-on for northern US and Canadian installations. At loading docks and exterior entries in cold climates, this eliminates a common line-item on the BOM and one more point of failure during winter weather.

Deployment Considerations:

• The 2A relay rating covers most door strikes and mag-locks directly, but verify draw before wiring — some high-power mag-locks (500+ lb holding force models) pull more than 2A and will need an external relay. Check the hardware spec sheet before rough-in.
• The standard X-35-BK (non-EWP) is rated 5%–95% non-condensing humidity. If you're installing at a car wash entrance, pool facility, or coastal exterior where condensation or direct water spray is realistic, spec the EWP variant instead — same electrical footprint, 316 stainless steel faceplate, 100% humidity rating.

The X-35-BK (often searched as X 35 BK) is particularly well-suited for multi-tenant commercial buildings where the SIP infrastructure is already in place and the integrator needs a single-endpoint solution that records to the VMS, handles door release, and doesn't require a dedicated power circuit at each entry point. It's a clean fit for lobby control stations, parking garage pedestrian gates, and controlled access corridors on existing SIP PBX deployments.
