Viking Electronics E-35-EWP Handsfree SIP Video Door Entry Phone
The Viking Electronics E-35-EWP is a stainless steel, vandal-resistant handsfree video entry phone built for demanding door and gate access points where you need SIP-integrated two-way audio, a color video feed, and hardware tough enough to survive both a Wisconsin winter and a Phoenix summer. The E-35-EWP (often searched as E 35 EWP) ships with a plastic rough-in box for flush mounting into a standard 4×4 electrical box, or pairs with the optional VE-5x5 surface enclosure for installations where cutting into the wall is not practical. This is not a consumer video doorbell — it is a commercial-grade SIP entry endpoint designed to register on your existing VoIP phone system and deliver a live video stream to any compatible video management client.
Why This Phone Belongs in Commercial Entry Applications
Most entry phones force a choice: weatherproofing or easy integration. The E-35-EWP delivers both. PoE Class 1 means the phone draws under 4 watts from a standard 802.3af switch port — no separate power supply, no conduit run for AC, no electrician coordination. SIP 2.0 (RFC 3261) compliance means it registers on Asterisk, Cisco UCM, Avaya, and virtually any standards-based VoIP platform without a proprietary gateway. The built-in color video camera provides a CCTV feed that can be monitored independently of the audio call, which matters in lobby and loading dock deployments where security staff need persistent visual coverage rather than just answering inbound calls.

Key Features
- Enhanced Weather Protection (EWP) up to 100% Humidity: The standard E-35 handles 5–95% non-condensing humidity. The EWP rating extends tolerance to 100% — meaning condensation, car washes, covered outdoor entries, and coastal fog are all within spec. If your installation is a covered parking garage or a coastal resort entry, this is the rating you need, not a standard IP66 dome camera enclosure.
- Operating Range -40°F to 140°F: This is a genuine full-range spec — not a narrow ±10°F indoor band. Surface-mount outdoor installations in northern climates that see -40°F wind chills, or southwestern environments that hit 140°F at a sun-baked metal door frame, stay within operating spec. Most commercial intercoms top out at 0°F or -4°F; this goes lower.
- PoE Class 1 (<4 Watts): Draws under 4W from a standard 802.3af switch port. On a 24-port 370W PoE budget switch, you can power 90+ of these phones without concern. No injector, no wall transformer, no separate power run — the single Cat5e/6 drop handles data and power together.
- SIP 2.0 RFC 3261 Compliance: Registers on any standards-compliant SIP server. No proprietary integration layer required. This means your existing PBX extension dial plan works — security staff on desk phones or softphones answer entry calls like any internal extension, without a dedicated intercom management app.
- Built-In High-Resolution Color Video Camera: Provides a live CCTV-style video feed in addition to the SIP audio path. Two-way door entry systems with integrated video eliminate the need to run a separate analog camera drop at the door — one cable does both the phone call and the video stream.
- Audio Codecs G.711u, G.711a, G.722: G.722 wideband codec support delivers HD audio (50Hz–7kHz) versus the 300Hz–3.4kHz narrowband of G.711. In a noisy loading dock or outdoor entry where ambient sound competes with speech, wideband audio meaningfully improves intelligibility without requiring any server-side configuration beyond codec negotiation.
- Maximum SPL 95 dB @ 1m: Loud enough to be heard over ambient noise in industrial and commercial entry environments — forklift traffic, HVAC exhausts, parking lot noise. At 95 dB at one meter, even a worker in hearing protection in a moderately noisy area can detect the alert tone.
- 2-Amp Relay Contacts: Integrated dry-contact relay for direct strike or magnetic lock control — no separate relay board required. Ties the door release to the SIP call flow, so the operator presses a DTMF key to unlock rather than running a separate control cable back to an access panel. Pair with a access control system for centralized credential management when relay-only control is insufficient.
- Non-Volatile Memory and Intelligent Call Progress Detection: The dialer retains its programming through power interruptions — useful in environments with unstable PoE infrastructure or utility power outages. Intelligent call progress detection means the unit correctly identifies ring, busy, and answer states rather than requiring timed fallback logic.
- RJ45 10/100 + 6 Gel-Filled Butt Connectors: The RJ45 handles the primary network/PoE drop. The six included gel-filled butt connectors are a practical detail — they allow field splices in wet or damp junction boxes without potting compound or heat shrink tools, which matters for flush-mounted installations in exterior walls where moisture intrusion at the junction is a real concern.
Integration and Compatibility
The E-35-EWP operates on 100BASE-Tx Ethernet and complies with IEEE 802.3af for PoE delivery and SIP 2.0 RFC 3261 for call signaling. It will register on any SIP-compliant PBX or hosted VoIP platform. The unit meets FCC Part 15 and Canada ICES-3 Class A emissions standards, making it deployable in commercial and light-industrial environments in both the US and Canada. The integrated 2-amp relay contacts interface directly with most electric strikes and magnetic locks rated for low-voltage dry-contact control. For deployments requiring higher current or fail-safe power sequencing, external relay boards are needed — the onboard relay is rated at 2A and should not be used to switch inductive loads above that threshold. Consult your VoIP accessories and cabling inventory for compatible PoE switches and structured cabling components to complete the installation.
Mounting Options
The E-35-EWP ships with a plastic rough-in box (4″ × 4″ × 2.12″) for flush installation into new or existing wall construction using a standard electrical box cutout. The overall phone footprint is 5″ × 5″ × 2.25″. Surface mount installations require the optional VE-5x5 enclosure, which is sold separately and adds the full EWP (100% humidity) capability. Both mounting configurations place the unit at standard ADA-accessible height when positioned correctly — verify rough-in height against your local accessibility code during rough-in framing.
Frequently Asked Questions
Q: What SIP platforms does the E-35-EWP work with?
A: The E-35-EWP is SIP 2.0 RFC 3261 compliant, meaning it will register on any standards-based SIP server — Asterisk, FreePBX, Cisco UCM, Avaya, 3CX, hosted VoIP platforms, and others. No proprietary gateway or adapter is required.
Q: Does the E-35-EWP require a separate power supply?
A: No. The E-35-EWP is powered via PoE Class 1 over the same Cat5e/6 Ethernet cable used for network connectivity. It draws under 4 watts and works with any IEEE 802.3af-compliant PoE switch or midspan injector. No separate AC power or transformer is needed.
Q: What is the difference between the standard E-35 and the E-35-EWP?
A: The E-35-EWP adds Enhanced Weather Protection, raising the humidity tolerance from 5–95% non-condensing (standard) to up to 100% — allowing deployment in fully exposed outdoor locations, covered parking structures, coastal environments, and car wash entry points where condensation or saturation is expected.
Q: Can the E-35-EWP control a door strike or magnetic lock directly?
A: Yes. The unit includes integrated 2-amp dry-contact relay outputs. Most electric strikes and magnetic locks rated for low-voltage dry-contact control can be wired directly. For inductive loads above 2A or fail-safe sequencing requirements, an external relay board is recommended.
Q: What are the flush mounting dimensions for the E-35-EWP?
A: The phone itself measures 5″ × 5″ × 2.25″ overall. The included plastic rough-in box is 4″ × 4″ × 2.12″ and fits a standard 4×4 electrical box cutout. Surface mounting requires the optional VE-5x5 enclosure, sold separately.
Q: Is the E-35-EWP approved for use in Canada?
A: Yes. The E-35-EWP meets FCC Part 15 (US) and Canada ICES-3 Class A emissions standards, making it compliant for commercial installation in both the United States and Canada.
I work with a lot of SIP entry phone deployments and the spec that makes or breaks an outdoor installation is temperature range — the E-35-EWP's -40°F to 140°F operating range is the widest I see regularly quoted at this price tier, and it's a real number, not a conservative indoor estimate padded with marketing margin. If you're specifying entry phones for a northern-climate outdoor vestibule or a sun-exposed southwestern loading dock, this is the unit I reach for first.
Technical Highlights:
- PoE Class 1 (<4W): At under 4 watts, this is one of the most switch-budget-friendly entry phones on the market. A standard 802.3af port handles it with headroom to spare — no need to audit your PoE switch budget or upgrade to 802.3at for this device.
- G.722 Wideband Audio: Most installers overlook codec selection on entry phones, but G.722 wideband (50Hz–7kHz) makes a real difference at a noisy loading dock versus the 300Hz–3.4kHz narrowband G.711 you get from cheaper units. If the receiving desk phone also supports G.722, the call quality improvement is audible and reduces repeat-yourself friction at busy entries.
- Integrated 2A Relay + Non-Volatile Memory: The relay lets you tie door release directly into the SIP call flow via DTMF — no separate relay panel needed for a single-door install. Non-volatile memory means a power cycle at a remote gate doesn't wipe the dialer configuration, which saves a service truck roll.
Deployment Considerations:
- The EWP rating (up to 100% humidity) requires the optional VE-5x5 surface enclosure for surface-mount installs — flush mounting with just the included rough-in box provides the standard 5–95% non-condensing rating, not EWP. Confirm which humidity spec you're designing to before the rough-in phase.
- The 2A relay contact rating is adequate for most electric strikes but watch for inductive loads — solenoid-heavy mag locks at higher current draws need an external relay board interposed, or you risk contact wear and erratic operation over time.
The E-35-EWP is best suited to covered outdoor lobbies, secure parking structure pedestrian gates, and commercial building main entries where you need SIP integration into an existing phone system, a live video feed at the door, and hardware that won't require a service call after the first hard winter.
