Viking X-35-BN with Enhanced Weather Protection (EWP) - X-35-BN-EWP

Viking Electronics X-35-BN-EWP IP Video Intercom with Enhanced Weather Protection

The Viking Electronics X-35-BN-EWP is a SIP-compliant IP video intercom built for outdoor entry points that face real weather — standing water, condensation, driving rain, and temperature swings that would kill a standard unit. Where the base X-35-BN tops out at 95% non-condensing humidity, the X-35-BN-EWP handles up to 100% humidity and operates across a -40°F to 140°F range, making it the variant to specify when the installation is exposed to precipitation rather than just ambient moisture. It integrates directly into SIP VoIP phone systems and delivers up to 1080p video to both the answering station and a dedicated NVR stream with audio — no separate video encoder required.

Overview

The X-35-BN-EWP occupies a 5" × 5" × 2.25" footprint behind a 14-gauge stainless steel faceplate — the kind of construction spec that matters when the unit is surface-mounted at a loading dock or parking structure entry where it will get bumped, hosed down, or hit with windblown debris. Power comes from standard 802.3af PoE (Class 1, under 4 watts), which means a basic PoE switch or injector handles it without budget line items for a local power supply. The unit ships at 1.6 lbs with the EWP package — slightly heavier than the standard variant due to the added sealing.

Key Features

• Enhanced Weather Protection — Up to 100% Humidity: The EWP treatment seals the unit against condensation and direct precipitation. If your installation is a covered vestibule with no direct rain exposure, the standard X-35-BN at 95% non-condensing will serve fine and saves a few dollars. If the unit faces open sky, takes wind-driven rain, or is mounted in a cold-storage environment where condensation is routine, the X-35-BN-EWP is the correct model.
• -40°F to 140°F Operating Range: That lower bound handles unheated parking structures and northern outdoor installations without supplemental heaters. The 140°F upper limit covers direct sun exposure in hot climates — useful for south-facing walls in desert environments where enclosure temps can spike well above ambient air temperature.
• Up to 1080p SIP Video Calling: The intercom delivers HD video to any SIP-compatible endpoint that supports video — compatible IP phones, softphones, or video-capable SIP clients. Image quality at the door is determined by the negotiated SIP video session, not just the camera hardware.
• Separate NVR Stream with Audio: Beyond the live SIP call, the unit provides an independent network video recorder stream. This lets you archive entry events without routing video through your phone system — the access control and surveillance paths stay cleanly separated. H.264 and MJPEG encoding are both supported, giving you codec flexibility based on your recorder's capabilities and storage budget.
• 126° Wide Viewing Angle: At 126 degrees, a single unit covers a standard doorway and captures anyone approaching from either side — useful for double-door entries and wide vestibules where a narrow field of view would leave blind spots at the edges of the frame.
• PoE Class 1 — Under 4 Watts: Drawing less than 4 watts, this is one of the lightest PoE loads you'll put on a switch. A 48-port 802.3af PoE switch budgeted at 15.4W per port has no difficulty powering a bank of these intercoms alongside cameras and access control readers on the same infrastructure.
• SIP 2.0 (RFC 3261) and 1000BASE-T: Standard SIP compliance means the unit registers to any RFC 3261-compliant SIP server — hosted PBX, on-premise Asterisk, Cisco UCM, or a SIP trunk provider. Gigabit Ethernet (1000BASE-T) ensures the network connection won't be a bottleneck for video quality.
• Audio Codecs — G.711u, G.711a, G.722: G.722 wideband audio delivers noticeably clearer speech than narrowband G.711 when the answering device supports it — relevant for installations where background noise at the door (traffic, HVAC, loading equipment) makes clear communication critical.
• 2-Amp Relay Contacts: The onboard relay lets you wire door strike or gate control directly to the intercom — no separate relay module needed for basic single-door access. Verify your door hardware's current draw stays within the 2-amp contact rating before specifying.
• 14-Gauge Stainless Steel Faceplate: Heavier gauge than most residential or light commercial intercoms. Resistant to casual vandalism and environmental wear. Appropriate for unattended entry points in commercial and industrial settings.

Integration and Compatibility

The Viking Electronics intercom line follows SIP 2.0 (RFC 3261) throughout, so the X-35-BN-EWP registers to the same SIP infrastructure you're already managing — no proprietary middleware, no vendor-specific call manager required. The separate NVR stream feeds directly into ONVIF-compatible video management systems via H.264 or MJPEG. For access control integration, the 2-amp relay output handles door strike or magnetic lock control within the intercom itself, though more complex multi-door or credential-based scenarios will require pairing with a dedicated access control panel. Audio codec negotiation (G.711u, G.711a, G.722) is handled automatically during SIP session setup based on endpoint capabilities.

Frequently Asked Questions

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

A: The EWP variant adds Enhanced Weather Protection sealing that raises the humidity tolerance from 95% non-condensing (standard) to up to 100%, making it suitable for installations exposed to direct precipitation or condensation. The operating temperature range and all other specs remain the same.

Q: Does the X-35-BN-EWP require a separate power supply?

A: No. It draws power via standard 802.3af PoE (Class 1, under 4 watts). Any 802.3af-capable PoE switch or midspan injector will power it with no additional power supply needed.

Q: What SIP servers is the X-35-BN-EWP compatible with?

A: The unit complies with SIP 2.0 (RFC 3261) and should register to any standards-compliant SIP server — including Asterisk, FreePBX, Cisco Unified Communications Manager, and hosted SIP/VoIP providers. Confirm video codec support on your SIP server if 1080p video calling is required.

Q: Can the X-35-BN-EWP record video independently, or does it only stream during a call?

A: The unit provides a separate NVR stream with audio that operates independently of the SIP call. This lets you record entry events continuously to an NVR or VMS without the call path being involved. H.264 and MJPEG are both supported for the NVR stream.

Q: What is the relay contact rating on the X-35-BN-EWP?

A: The onboard relay is rated at 2 amps. It can be used to directly control a door strike, magnetic lock, or gate release within that current rating. For hardware with higher current requirements, use an intermediate relay or power controller.

Q: Is the X-35-BN-EWP suitable for extreme cold environments?

A: Yes. The operating temperature range is -40°F to 140°F (-40°C to 60°C), which covers unheated outdoor installations in northern climates without supplemental heating.

The spec I look at first on the X-35-BN-EWP is the humidity ceiling — 100% with EWP versus 95% non-condensing on the standard variant. That gap sounds small until you're specifying a cold-storage facility entry, an outdoor parking structure in the Pacific Northwest, or any installation where the unit sits in a microclimate that regularly sees condensation. At that point the EWP model isn't optional, it's the correct SKU.

Technical Highlights:

• Sub-4W PoE Class 1: Drawing under 4 watts from 802.3af PoE, this intercom has one of the smallest power footprints of any IP video device you'll put on a switch. Budget a single 802.3af port and move on — no PoE+ switch, no injector math.
• Dual-Stream Architecture — SIP Call + Independent NVR: The simultaneous SIP video call and separate NVR stream with audio means you're not choosing between live answering and recorded evidence. H.264 and MJPEG give your recorder codec flexibility depending on your VMS license and storage budget.
• G.722 Wideband Audio: When the answering SIP endpoint supports G.722, speech clarity at a noisy industrial entry point — loading dock, parking gate, mechanical room — is noticeably better than G.711 narrowband. Worth confirming G.722 support on your desk phones or softphone clients before deployment.

Deployment Considerations:

• The 2-amp relay contact handles most door strikes and small magnetic locks directly, but verify your hardware's inrush current spec. Locks with high inrush at energize can exceed the contact rating momentarily — if in doubt, wire through an intermediate relay rated for the lock's actual load.
• The unit dimensions are 5" × 5" × 2.25" — confirm your surface backbox or gang box depth accommodates the 2.25" projection before rough-in. Flush mounting in a standard single-gang box will not work without an extension ring.

The X-35-BN-EWP is the right call for unattended outdoor entry control — loading dock doors, cold-storage vestibules, parking structure gates, and exterior building access points — anywhere a standard intercom would fail from condensation or temperature extremes within the first winter season.
