Viking E-35 PoE Handsfree Video Entry Phone Vandal-Resistant

Viking Electronics E-35 Handsfree Video Entry Phone with Color Camera

The Viking Electronics E-35 is a vandal-resistant, weather-proof handsfree door entry phone that combines SIP VoIP communication with a built-in analog NTSC color video camera — purpose-built for access points where you need two-way voice and live video over a single Ethernet run. The E-35 (often searched as E 35) draws under 4 watts via IEEE 802.3af PoE Class 1, so it won't strain your switch power budget, and it operates from -40°F to 140°F, making it a legitimate choice for northern exterior vestibules and loading dock entries that defeat most commercial devices.

Overview

The E-35 targets facilities requiring integrated door communication and visual verification at controlled entry points: corporate lobbies, apartment building entries, school vestibules, industrial perimeter gates, and healthcare access control checkpoints. It flushes into standard 4-inch electrical boxes using the included rough-in box, or surface-mounts with an optional VE-5x5 adapter — two install paths that cover nearly every field condition without special fabrication.

Key Features

• PoE Class 1 (under 4W): Runs on any 802.3af-capable switch port without triggering power-budget alarms. No local power supply, no conduit run for 120VAC — one Cat5e/6 cable handles data and power both.
• SIP 2.0 (RFC 3261) over 100BASE-Tx: Registers natively on any standards-compliant SIP PBX or hosted UCaaS platform. No proprietary middleware, no extra gateway hardware to provision or license.
• G.711u, G.711a, G.722 Audio Codecs: G.722 delivers wideband (HD) audio at 16kHz — noticeably clearer than legacy 8kHz narrowband, which matters when a receptionist needs to accurately verify a visitor's name through background noise.
• 95 dB SPL @ 1m Speaker Output: Loud enough to cut through loading dock ambient noise, HVAC equipment, or busy lobby foot traffic without requiring staff to shout back.
• Built-in NTSC Color Video Camera with Wide Viewing Angle and Tilt/Swivel: Lets the answering party visually confirm identity before releasing a door strike — the tilt/swivel adjustment means you can dial in the frame to cover a wheelchair-height visitor or a tall exterior staircase without repositioning the entire unit.
• 2-Amp Relay Contacts: Sufficient to directly drive most electric door strikes and magnetic locks without an intermediate relay panel. Check your lock's inrush current spec — most fail-secure strikes fall well under 2A.
• -40°F to 140°F Operating Range with EWP Humidity to 100%: The Extended Weather Protection rating tolerates full condensation and rain ingress, not just splash resistance. This is the spec that separates the E-35 from indoor-only SIP intercoms dressed up in a metal housing.
• RJ45 10/100 + Six Gel-Filled Butt Connectors: The gel-filled connectors allow direct splice to existing two-conductor or CAT-cable field wiring without a punchdown block — useful on retrofits where the rough-in conduit is tight.

Integration and Compatibility

The E-35 registers as a standard SIP endpoint — configure it the same way you would any SIP desk phone: assign an extension, set a dial string for the door release relay, and route calls to a hunt group or operator. It is compatible with SIP-based VoIP phone systems from major PBX vendors. The 100BASE-Tx Ethernet interface connects to any managed or unmanaged PoE switch; for multi-door deployments consider pairing with a PoE network switch sized to your port and power requirements. FCC Part 15 and Canada ICES-3 Class A certification covers standard commercial installations in both the US and Canada. Overall unit dimensions are 5" x 5" x 2.25"; the included plastic electrical box is 4" x 4" x 2.12" — verify rough-in depth before ordering in renovation projects with shallow wall cavities.

Frequently Asked Questions

Q: Does the E-35 require a separate power supply?

A: No. The E-35 draws under 4 watts via standard IEEE 802.3af PoE (Class 1) — any 802.3af-capable switch port powers it directly over the same Cat5e/6 cable used for data. No local 120VAC outlet or power adapter is needed.

Q: What SIP PBX systems is the E-35 compatible with?

A: The E-35 implements SIP 2.0 per RFC 3261, the industry-standard protocol. It registers as a standard SIP endpoint on any RFC 3261-compliant PBX or hosted SIP platform. Consult your PBX vendor's intercom or door phone configuration guide for door-relay call routing specifics.

Q: Can the E-35 be installed outdoors in freezing climates?

A: Yes. The E-35 is rated from -40°F to 140°F and carries an Extended Weather Protection (EWP) humidity rating of up to 100% — it handles full condensation and rain, not just splash resistance, making it suitable for northern exterior entrances and unheated vestibules.

Q: What are the two mounting options for the E-35?

A: The E-35 can flush-mount into a standard 4" x 4" electrical box using the included rough-in box (electrical box dimensions: 4" x 4" x 2.12"), or surface-mount using the optional VE-5x5 adapter. The overall unit is 5" x 5" x 2.25".

Q: What relay output does the E-35 provide for door control?

A: The E-35 includes relay contacts rated at 2 amps, sufficient to directly drive most electric door strikes and magnetic locks without an intermediate relay panel. Verify the lock's inrush current does not exceed this rating.

Q: What audio codecs does the E-35 support?

A: The E-35 supports G.711u, G.711a, and G.722. G.722 enables HD wideband audio at 16kHz for noticeably clearer two-way conversation compared to legacy 8kHz narrowband codecs.

James Everett

The E-35 is one of the few SIP entry phones I'd specify without hesitation for an unheated northern exterior entry — the -40°F floor on the operating temperature isn't marketing copy, it's a real design constraint that rules out most competing units. Pair that with 100% EWP humidity tolerance and you have a device that will survive a Minnesota winter without heater accessories.

Technical Highlights:

• PoE Class 1 (<4W): Well inside 802.3af headroom — even a budget 8-port PoE switch with a 30W total budget can run multiple E-35 units simultaneously without port power management gymnastics.
• G.722 Wideband Audio: At 16kHz sample rate, voice intelligibility through the 95 dB SPL speaker is noticeably better than narrowband G.711-only intercoms — relevant anywhere ambient noise is a factor (dock doors, HVAC rooms, outdoor kiosks).
• 2A Relay Contacts: Covers direct drive of virtually all fail-secure electric strikes on the market today. Eliminates the relay module line item that adds cost and a failure point on competing entry phone deployments.

Deployment Considerations:

• The included rough-in box targets new construction or open-wall retrofits — confirm wall cavity depth is at least 2.12" before committing to flush mount on tile or masonry installations where the VE-5x5 surface adapter is the cleaner path.
• The video output is analog NTSC, not IP — it feeds a separate CCTV input or DVR, not your NVR. Plan the coax run separately from the Cat5e PoE run if you need recorded video from the door camera.

The E-35 is the right spec for controlled-entry points in K-12 schools, multifamily building lobbies, and light industrial facilities where you need a single-cable install, sub-zero temperature tolerance, and direct SIP registration without proprietary hardware — not a general-purpose IP camera replacement.
