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

Viking Electronics X-35-SS-EWP HD SIP IP Video Intercom with Enhanced Weather Protection

Overview

The Viking Electronics X-35-SS-EWP is a hardened outdoor IP video intercom built for SIP VoIP environments where standard weather resistance isn't enough. The EWP (Enhanced Weather Protection) variant is the answer when the unit faces direct precipitation, heavy condensation, or coastal humidity — conditions that push standard intercoms past their limits. Where the base X-35-SS handles typical outdoor exposure, the X-35-SS-EWP (often searched as X 35 SS EWP) extends humidity tolerance to 100%, making it viable for wash-down areas, covered entrances exposed to blowing rain, and maritime-adjacent deployments.

This is a flush-mountable or surface-mountable 1080p video intercom purpose-built for Viking Electronics SIP-based installations — gate entry, secured building access, and industrial access control points where hands-free voice communication and live video are both mandatory. It integrates directly with SIP 2.0 (RFC 3261) phone systems and service providers, removing the need for proprietary call servers or added middleware.

Key Features

• 1080p HD Video with 126° Viewing Angle: A 126-degree field of view is wide enough to capture the full entry area at a standard door or gate — you get context around the caller, not just a tight face shot. Combined with 1080p resolution, the image holds enough detail for identity verification at typical intercom distances without requiring optical zoom.
• H.264 + MJPEG Dual Encoding: H.264 compression keeps recorded stream bandwidth manageable on your network, while MJPEG is available for clients or VMS integrations that need individual frame access without decoding dependencies. Both are supported simultaneously, so you don't have to choose at commissioning time.
• Enhanced Weather Protection to 100% Humidity: Standard outdoor intercoms typically cap at 95% non-condensing. The EWP rating extends to 100% humidity — a meaningful difference in covered loading docks, carwash facilities, food processing entrances, or coastal installations where condensation is continuous rather than occasional.
• -40°F to 140°F Operating Range: This temperature envelope covers unheated outdoor enclosures in northern climates down to -40°F in winter and sun-baked metal door frames pushing 140°F in summer. Both extremes are real deployment conditions that cheaper intercoms don't reliably survive.
• 316 Stainless Steel Faceplate: 316-grade stainless (not the more common 304) offers meaningfully better resistance to chloride corrosion — relevant for coastal environments, food service, and chemical plant access points where surface pitting and rust would otherwise degrade the installation appearance and eventually the seal.
• PoE Class 1 (Under 4 Watts): Drawing less than 4W, this intercom runs on 802.3af PoE — any standard PoE switch port can power it. You won't need to upsize to PoE+ switches or add local power supplies, and it won't strain a switch with a tight power budget. A single Cat5e/Cat6 run handles power, data, and audio simultaneously.
• 2-Amp Relay Contacts: The onboard dry-contact relay rated at 2A gives you direct control of electric door strikes, magnetic locks, or gate controllers — no separate relay module, no extra wiring run. The intercom itself handles the access control switching.
• SIP 2.0 RFC 3261 Compliant with G.711u/a and G.722 Audio: Native SIP 2.0 integration means this device registers directly on your IP PBX (Cisco, Avaya, FreePBX, 3CX, and others) the same way a desk phone does. G.722 wideband audio support delivers noticeably clearer voice quality than standard G.711 — a practical advantage at noisy exterior entry points where 90 dB SPL speaker output needs to cut through ambient sound.
• 1000BASE-T Gigabit Network Interface: Gigabit Ethernet is standard here, eliminating any bottleneck on video streaming even if you're running 1080p continuously to a recording system.
• Flush or Surface Mount Options: Factory support for both flush (in-wall backbox) and surface mount (conduit box) installs means this unit adapts to new construction and retrofit scenarios without requiring additional adapter hardware beyond the chosen backbox.

Integration & Compatibility

The X-35-SS-EWP operates as a standard IP video intercom on any SIP 2.0 (RFC 3261) compatible phone system. It registers as a SIP endpoint — configure it the same way you'd provision a SIP door phone. Audio codec support includes G.711u, G.711a, and G.722, so the unit negotiates the best available codec with your PBX automatically. The 802.3af PoE compliance means it works with virtually any managed or unmanaged PoE switch without special configuration. The onboard 2A relay integrates directly with most commercial electric strikes and mag-lock controllers. For access control applications requiring video verification at the door, this intercom can be paired with your existing SIP-based door station workflow — no proprietary software license required on the intercom side.

Frequently Asked Questions

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

A: The X-35-SS handles standard outdoor humidity up to 95% non-condensing. The X-35-SS-EWP adds Enhanced Weather Protection (EWP), extending humidity tolerance to 100% — designed for installations exposed to direct precipitation, condensation, or wash-down conditions where the base model's rating is insufficient.

Q: Does the X-35-SS-EWP work with any SIP phone system?

A: Yes. The X-35-SS-EWP is SIP 2.0 (RFC 3261) compliant and registers as a standard SIP endpoint on any compatible IP PBX or SIP service provider. It supports G.711u, G.711a, and G.722 audio codecs for automatic codec negotiation with your phone system.

Q: What PoE class does the X-35-SS-EWP require?

A: The X-35-SS-EWP is PoE Class 1, drawing under 4 watts. It runs on standard 802.3af PoE — any 802.3af-capable switch port is sufficient. PoE+ (802.3at) is not required.

Q: Can the X-35-SS-EWP directly control a door strike or magnetic lock?

A: Yes. It includes onboard dry-contact relay contacts rated at 2 amps, allowing direct wiring to electric door strikes, magnetic locks, or gate controllers without a separate relay module.

Q: What video resolution and compression does the X-35-SS-EWP support?

A: The unit records and streams at up to 1080p HD using H.264 compression. MJPEG is also supported for frame-accurate access or VMS compatibility that requires it.

Q: What are the operating temperature limits for the X-35-SS-EWP?

A: The X-35-SS-EWP operates from -40°F to 140°F (-40°C to 60°C), covering extreme cold-weather outdoor installations and high-heat environments such as sun-exposed metal door frames in summer.

The spec that earns the X-35-SS-EWP its place in a project isn't the camera — it's the 100% humidity EWP rating. Most outdoor intercoms stop at 95% non-condensing, which sounds close enough until you're commissioning an entrance vestibule that gets blasted with humid air every time someone opens the door, or a covered loading dock that never fully dries out. That's where the X-35-SS-EWP is the correct part number and the base X-35-SS isn't.

Technical Highlights:

• PoE Class 1 (<4W): At under 4 watts, this is one of the lowest-draw PoE intercoms you'll spec. On a 48-port 370W switch, you could run 90 of these without hitting the power budget — not a realistic scenario, but it illustrates how little it taxes your switch infrastructure. 802.3af standard ports only, no PoE+ required.
• 2A Relay Output: The onboard relay handles most commercial door strikes and mag-locks directly. Verify your lock's inrush current stays under 2A — some larger mag-locks spike above this momentarily and need a separate relay in line.
• G.722 Wideband Audio + 90 dB SPL Speaker: G.722 is genuinely better than G.711 at noisy entry points. The 90 dB SPL output at 1 meter is loud enough for most exterior applications without adding an external horn speaker — reduces hardware count and weatherproofing complexity at the entry point.
