Viking E50-SS-EWP Stainless Steel Video Entry Phone IP67 EWP

Viking Electronics E50-SS-EWP Stainless Steel Entry Phone with Color Video Camera

The Viking Electronics E50-SS-EWP is a telephone-line-powered stainless steel entry phone combining two-way audio, a color video camera, and auto-disconnect — built for demanding door and gate entry points where weather resistance, vandal deterrence, and reliable hands-free communication all have to coexist. Flush-mounting into a single-gang box or surface-mounting with an optional VE-3x5 enclosure, the E50-SS-EWP covers commercial lobbies, apartment vestibules, gated facilities, and industrial access points where aluminum faceplates or plastic housings simply aren't durable enough.

Overview

Entry phones that depend on separate power supplies introduce wiring complexity and failure points. The E50-SS-EWP draws power directly from the telephone line — requiring a minimum 18V DC talk battery voltage and at least 20mA loop current — which means no power run to the door, no transformer to mount nearby, and no second cable to pull. That single-pair simplicity is one of the most underappreciated aspects of this form factor in retrofit access projects.

The blue LED indicator is functional, not decorative: it runs continuously to help visitors locate the push button in low-light conditions, dims to signal the line is off-hook, and flashes on incoming ring. It's the kind of feedback loop that cuts down on support calls from confused visitors.

Key Features

• 18-Gauge 304 Stainless Steel Faceplate (4.875" x 3.125" x 0.18"): 304 stainless resists surface corrosion in coastal and high-humidity environments. The 0.18" thickness gives the plate its rigidity without adding bulk — the entire assembly ships at 1.0 lb, making single-person installs practical.
• 316 Stainless Steel Push Button: 316 grade offers superior chloride resistance compared to 304 — the right call for marine environments, food processing areas, or anywhere salt spray or cleaning chemicals are routine. The push button carries an IP67 ingress rating, meaning it's sealed against temporary submersion up to 1 meter, not just splash resistance.
• EWP (Enhanced Weather Protection) — IP66 System Rating: The full assembly with the optional VE-3x5 enclosure achieves IP66, protecting against powerful water jets from any direction. Operating humidity reaches 100% in EWP configuration, versus 5–95% non-condensing on the standard model. If the installation faces direct rain exposure or pressure washing during building maintenance, the EWP variant is the correct choice.
• -30°F to 150°F Operating Range: That's a 180°F span — functional in Minnesota winters and Arizona mechanical-room summers without special thermal management. Most competing plastic-body entry phones cap out well below 150°F, which matters if the unit will be mounted on a south-facing metal door in a hot climate.
• Telephone Line Powered (Minimum 18V DC / 20mA): No auxiliary power required. The phone draws from the existing POTS loop — a significant installation cost reduction in retrofits where running new cabling to the door is expensive. Confirm your PBX or analog line supplies at least 18V talk battery; most modern FXS ports do, but some VoIP ATAs run lean.
• Auto Disconnect (300ms Minimum): The unit automatically terminates the call after the door is released, preventing line tie-ups if the visitor walks away without hanging up. The 300ms minimum disconnect time is fast enough that it won't delay subsequent calls on multi-door systems.
• 62dB Maximum Speaker Volume @ 1m: Adequate for standard commercial lobbies and covered entryways. In high-ambient-noise environments — loading docks, mechanical rooms, outdoor exposed locations near HVAC equipment — evaluate whether a horn speaker supplement is warranted.
• 25V AC RMS Minimum Ring Voltage: Standard POTS and most analog PBX ports comfortably exceed this. If you're driving the phone from a VoIP ATA, verify ring voltage output before specifying — some budget ATAs deliver only 20–22V RMS, which may cause intermittent ring failures.
• REN 0.8A: Low ringer equivalence number means the E50-SS-EWP imposes minimal load on the line. You can add a secondary ringer or door strike relay on the same loop without hitting the typical 5.0 REN limit on most lines.
• Color Video Camera: Provides visual verification of visitors at the door — standard in commercial access applications where audio-only entry phones no longer meet liability or security policy requirements. Connects to a compatible video door phone monitor or VoIP system with video capability.

Integration and Compatibility

The E50-SS-EWP integrates with Viking Electronics analog entry systems and connects to standard POTS lines, PBX analog extensions, or VoIP ATAs with FXS ports that meet the 18V DC / 20mA loop requirements. For installations requiring surface mounting, the optional VE-3x5 enclosure pairs with the E50-SS-EWP to achieve the full IP66 EWP system rating — plan for this accessory when conduit or wall construction prevents flush mounting in a single-gang box. This product belongs in the broader category of door entry phones and pairs logically with a compatible video door phone monitor for visual verification at the receiving station. For multi-door commercial installations, reference Viking's access control line for coordinated door strike and relay management.

Frequently Asked Questions

Q: What is the difference between the standard E50-SS and the E50-SS-EWP?

A: The EWP (Enhanced Weather Protection) version is designed for use with the optional VE-3x5 surface mount enclosure, achieving an IP66 system ingress rating and supporting operating humidity up to 100%. The standard model is rated for 5–95% non-condensing humidity and does not carry the IP66 system-level rating.

Q: Does the E50-SS-EWP require a separate power supply?

A: No. The E50-SS-EWP is telephone line powered, drawing from the POTS loop with a minimum 18V DC talk battery and 20mA loop current. No auxiliary power supply or transformer is required at the door location.

Q: What ingress protection ratings apply to the E50-SS-EWP?

A: The push button switch carries an IP67 rating (sealed against temporary submersion up to 1 meter). The full assembly in EWP configuration with the optional VE-3x5 enclosure achieves IP66 (protected against powerful water jets from any direction).

Q: What is the operating temperature range of the E50-SS-EWP?

A: The unit operates from -30°F to 150°F (-34°C to 65°C), covering harsh winter installations and high-temperature environments such as south-facing metal doors or warm mechanical rooms.

Q: Will the E50-SS-EWP work with a VoIP ATA instead of a traditional POTS line?

A: It can, provided the ATA's FXS port delivers at least 18V DC talk battery voltage, 20mA loop current, and a minimum 25V AC RMS ring voltage. Some budget ATAs fall short on ring voltage — verify the ATA's specifications before deploying.

Q: What mounting options are available for the E50-SS-EWP?

A: The faceplate (4.875" x 3.125" x 0.18") flushes into a standard single-gang electrical box. For surface mounting, Viking's optional VE-3x5 enclosure is required and also provides the EWP IP66 system-level weather protection.

Karl Wilson

The E50-SS-EWP earns its place on commercial and institutional door access projects primarily because of how it handles power: telephone line powered at 18V DC / 20mA means no additional home-run cable to the door, no transformer, and no new circuit to the electrical panel. On a retrofit where you're threading wire through finished walls or conduit already at capacity, that single pair is the deciding factor. The 316 stainless push button with IP67 rating is the other spec I'd flag immediately — it's not just weather resistance, it's corrosion resistance against chlorides, which matters in coastal installations, food service, and anywhere the door gets cleaned with aggressive chemicals.

Technical Highlights:

• IP67 Push Button / IP66 EWP System: The push button itself is rated for temporary submersion to 1 meter; with the VE-3x5 enclosure the full assembly hits IP66 — powerful water jet resistant. Two distinct ratings serving different failure modes in one deployment.
• -30°F to 150°F Operating Range: A 180°F thermal span without derating or thermal management accessories. Most analog entry phones in this class don't reach 150°F — this one handles south-facing metal door installations in hot climates that would cook a standard unit.
• 300ms Auto Disconnect: Fast enough to free the line without noticeable delay after door release, preventing tie-ups on multi-door PBX configurations where the same extension serves several entry points.

Deployment Considerations:

• Verify your FXS port or PBX analog extension delivers the minimum 25V AC RMS ring voltage before installation. Budget VoIP ATAs commonly deliver only 20–22V RMS, which causes intermittent ring failures that are difficult to diagnose after the unit is already mounted and wired.
• The EWP rating and IP66 system certification only apply when the VE-3x5 enclosure is installed — surface-mounting the E50-SS-EWP directly to a wall without the VE-3x5 drops the assembly to the standard humidity envelope (5–95% non-condensing). If the installation is exposed, spec the enclosure from the start.

The E50-SS-EWP is best suited to institutional and light-industrial applications — apartment building vestibules, gated manufacturing facilities, food processing plant entry points — anywhere you need corrosion-grade hardware, line-powered simplicity, and a documented IP rating on the push button that holds up under an inspector's or insurer's review.
