Viking E-75-SS Stainless Entry Phone w/ Prox Card Reader & Video

Viking Electronics E-75-SS Stainless Steel Entry Phone with Proximity Card Reader and Color Video Camera

The Viking Electronics E-75-SS is a compact, all-in-one entry phone that combines a 420-line analog color video camera, a 125KHz proximity card reader, and a handsfree speakerphone into a flush-mountable 304 stainless steel faceplate — purpose-built for commercial doors, vestibules, and controlled-access lobbies where you need credential verification, visual confirmation, and two-way audio from a single device. This is a telephone-line-powered unit, meaning no separate power supply or data network is required at the door — a meaningful advantage in retrofit scenarios where conduit runs are limited.

Overview

The E-75-SS addresses a common installation challenge: delivering access control, visitor verification, and intercom capability from a footprint no larger than a double gang box. The 304 brushed stainless faceplate measures 4.875" x 4.938" x 0.17" — it lays essentially flush with the wall surface. The phone body itself is 2.84" x 1.8" x 1.65", tucking entirely behind the plate. For locations where a recessed box isn't available, the optional VE-5x5 surface mount enclosure converts this to a surface-mount installation without altering the faceplate appearance. This unit ships at 1.2 lbs, making single-person installation straightforward. If you're evaluating entry phones for multi-door deployments, the E-75-SS is worth comparing against IP-based variants for total infrastructure cost.

Key Features

• 420-Line Analog Color Video Camera: The built-in camera delivers 420 horizontal lines of resolution — standard-definition analog output that integrates directly with analog DVRs and video door phone systems without an encoder or IP conversion. The 80° horizontal / 60° vertical / 100° diagonal field of view captures the full face and upper body of a visitor standing at a standard door, giving the inside station enough visual context for identification decisions.
• 125KHz Proximity Card Reader (26-bit Wiegand): The onboard reader supports 125KHz proximity credentials and outputs standard 26-bit Wiegand data — the most widely deployed access control format in commercial installations. This means it wires directly into virtually any legacy or modern access control panel without protocol adapters. If your site already runs HID or EM4100-compatible cards, residents or staff don't need new credentials.
• Telephone-Line Powered Operation: The E-75-SS draws power from the phone line itself, requiring a minimum 25V AC RMS ring voltage. No 12VDC/24VAC power supply at the door, no PoE switch port, no separate transformer — just the twisted pair from your telephone system or door phone controller. In buildings with existing intercom wiring, this often eliminates the need for any new electrical work at the door.
• IP67-Rated Push Button Switch: The call button carries an IP67 rating, meaning it withstands temporary submersion — well beyond what most covered entry points will ever see. In practice, IP67 on the switch means driving rain, ice melt runoff, and power-washing the entry area won't cause intermittent contact failures or corrosion over time. The overall weather protection on the EWP variant reaches IP66 for the full housing.
• 304 Stainless Steel Faceplate — Multiple Finishes: The faceplate is 304-grade stainless, available in brushed stainless, oil rubbed bronze, satin black, and satin white. This matters in architect-driven commercial projects where the entry hardware must match door hardware finishes. The 0.17" plate thickness keeps the surface profile minimal against door frames or masonry surrounds.
• Wide Operating Temperature Range (-30°F to 150°F): The camera and phone both operate across this range, which covers unheated vestibules in northern climates down to -34°C and direct sun exposure in southern climates. Most competitive units rate only to -4°F (-20°C), so this is a meaningful advantage for outdoor installations in cold-weather regions.
• Microphone and Speaker Volume Controls: Onboard adjustable mic and speaker levels let you tune audio for the ambient noise environment at the door — loading docks, street-facing entries, or quiet office lobbies all require different settings. This is an installer-level control, not an end-user feature, and it saves callbacks after commissioning.
• Flush Mount in Double Gang Box: Standard double gang rough-in means electricians and low-voltage contractors already have the right boxes on hand. No proprietary back boxes, no special rough-in templates beyond the included mounting hardware.

Integration and Compatibility

The E-75-SS is designed for integration into traditional telephone-based door entry systems — it requires a POTS-style phone line or a door phone controller that provides ring voltage. The 26-bit Wiegand output from the card reader connects to any access control panel with a standard Wiegand input, including panels from HID, Lenel, Software House, Bosch, and DSC. The analog video output feeds any composite video input: analog DVRs, standalone video door phone monitors, or a video matrix. This is not an IP camera — there is no Ethernet port, no ONVIF profile, and no RTSP stream. If your new installation is fully IP-based, evaluate whether an analog-to-IP encoder is acceptable overhead or whether a VoIP entry phone better fits the architecture. For mixed analog/IP environments, pairing this unit with a DVR and a traditional access panel remains a clean, low-complexity solution. For PoE switch planning in broader access control deployments, review the PoE switch selection guide. If the installation needs surface mounting, the optional VE-5x5 surface mount enclosure is the correct companion accessory for this unit (sold separately).

Frequently Asked Questions

Q: Does the E-75-SS work with IP-based access control systems?

A: The card reader outputs 26-bit Wiegand data, which is compatible with most IP-based access control panels that include a Wiegand input. However, the phone itself requires a telephone line (not Ethernet), and the video output is analog composite — not an IP stream. Integration with a fully IP intercom or VMS platform would require additional hardware such as an analog telephone adapter and a video encoder.

Q: What proximity card formats are compatible with the E-75-SS?

A: The reader operates at 125KHz and outputs 26-bit Wiegand. This is compatible with standard HID Prox, EM4100, and other 125KHz credential formats. It does not support 13.56MHz (MIFARE, DESFire) smart cards or mobile credentials.

Q: Can the E-75-SS be installed outdoors in cold climates?

A: Yes. The operating temperature range is -30°F to 150°F, which covers most North American outdoor environments including unheated vestibules and exposed entries in northern climates. The push button switch carries an IP67 rating for water ingress resistance.

Q: What mounting options are available for the E-75-SS?

A: The unit flushes into a standard double gang electrical box. For surface mounting — on a post, pillar, or masonry wall without a recessed box — the optional VE-5x5 enclosure (sold separately) is the recommended accessory.

Q: What power source does the E-75-SS require?

A: It is telephone-line powered, drawing power from the phone line itself. A minimum ring voltage of 25V AC RMS is required. No separate power supply, PoE injector, or transformer is needed at the door.

Q: What finish options are available for the E-75-SS faceplate?

A: The 304 stainless steel faceplate is available in brushed stainless steel, oil rubbed bronze, satin black, and satin white to match door hardware finishes in commercial and mixed-use facilities.

The E-75-SS earns its place in retrofit access control projects specifically because of its telephone-line-powered architecture — when you're threading new wiring through finished walls is not an option, the ability to commission a full entry phone, card reader, and video camera over an existing twisted pair run with 25V AC RMS ring voltage changes the project economics substantially. I've spec'd this unit on multi-tenant lobbies and secured vestibules where the alternative was cutting drywall to run 18/2 power and Cat6 separately to the door.

Technical Highlights:

• 26-bit Wiegand Output: Connects directly to virtually every legacy and modern access panel on the market without a protocol bridge — keeps the door controller wiring to a single Wiegand data pair rather than adding an IP reader module.
• -30°F to 150°F Operating Range: Covers unheated Minnesota vestibules in winter and west-facing Texas entry walls in summer — a wider thermal tolerance than most entry phones in this class, and relevant when the door is exposed rather than under a canopy.
• IP67 Push Button / IP66 EWP Housing: IP67 on the call button means the switch mechanism survives direct water exposure events that would corrode a lesser contact. If the installation is in a wash-down environment or regularly exposed to spray, specify the EWP variant for the full IP66 housing rating.

Deployment Considerations:

• The 420-line analog video output requires a composite video input at the head end — plan for an analog DVR, a dedicated video door phone monitor, or a composite-to-IP encoder if your recording system is fully IP. Don't assume an NVR with no analog inputs can receive this signal directly.
• The 125KHz card reader does not support modern 13.56MHz smart card credentials (MIFARE, DESFire, SEOS). If the site is in the process of migrating to high-frequency credentials or mobile access, this reader won't follow — budget for a credential transition or evaluate a higher-frequency reader at the door now.

The E-75-SS (often searched as E 75 SS) is the right specification for Class B multi-tenant residential lobbies, small commercial office entries, and any retrofit project where the existing intercom conduit is already in the wall and adding a dedicated power circuit to the door is cost-prohibitive.
