Viking Electronics E-32T-SS-IP IP Intercom with Secure SIP and Web UI
The Viking Electronics E-32T-SS-IP is a flush-mount IP intercom engineered for demanding entry-control environments — think parking structures, loading docks, exterior vestibules, and industrial facilities where exposure, vandalism risk, and reliable voice communication all have to be solved at once. It installs into a standard double-gang box or pairs with an optional VE-Series surface-mount box, keeping your rough-in options flexible. Power comes via PoE Class 2 (under 6.5W), so there is no local transformer and no separate power run to pull.
Key Features
- 14-Gauge 316 Stainless Steel Faceplate (#4 Brushed Finish): 316-grade stainless resists chloride corrosion, making this the right material for coastal installations and food-processing areas where 304 or painted steel would pit or rust. The brushed finish also reduces the visibility of surface scratches over time.
- IP66 Ingress Protection: Rated to keep out powerful water jets and complete dust exclusion — suitable for outdoor mounting without a protective enclosure. If your application involves actual submersion, IP66 is not sufficient; step up to an IP67- or IP68-rated device. The E-32T-SS-IP is built for rain and wash-down, not flooding.
- PoE Class 2 Power (under 6.5W): Draws less than 6.5W from a standard 802.3af switch port. That keeps it off the high-wattage budget and means virtually any managed or unmanaged PoE switch can power it without a port reservation. No local transformer, no AC outlet, no conduit for power — just the Cat5e/6 run you are already pulling for data.
- 90 dB SPL at 1 Meter: Loud enough to cut through ambient noise on a loading dock or in a lobby with HVAC running. If your site has sustained noise above 85dBA, plan for a speaker volume test during commissioning — 90dB SPL at 1m is a solid baseline, but speaker distance and room reflection affect real-world intelligibility.
- SIP 2.0 (RFC 3261) with Secure SIP and Web UI: Registers natively to any SIP-compliant phone system or hosted PBX. Configuration is browser-based — no proprietary software client required. Secure SIP support means the signaling path can be encrypted, relevant for enterprise sites with strict network security policies.
- G.711u, G.711a, and G.722 Audio Codecs: G.722 delivers wideband (HD) audio at 50–7,000 Hz when your PBX supports it — noticeably clearer voice compared to narrowband G.711. In practice, most SIP desk phones and softphones support G.722, so you get HD audio end-to-end without extra licensing.
- 1000BASE-T Gigabit Ethernet (RJ45): The single RJ45 runs at up to 1Gbps, which is far above what voice requires — but it means you can drop this on a gigabit infrastructure run without a media converter or speed mismatch concern.
- -40°F to 140°F (-40°C to 60°C) Operating Range: Rated for genuine cold-climate deployments — Minnesota winters, Canadian warehouse docks — without a heater kit. The upper end of 140°F also covers sun-exposed southern facades where surface temps can spike well above ambient air temperature.
- Programmable Relay Output: The on-board relay lets the E-32T-SS-IP activate a door strike, gate controller, or other dry-contact device directly on call answer — eliminating the need for a separate relay module at the door and simplifying wiring for single-door access points.
- Gel-Filled Butt Connectors (x3 included): Moisture-sealed splicing connections are included for field wiring — directly addressing the outdoor/wet-location use case where unprotected wire nuts would wick water into the connection over time.
Integration and Compatibility
The E-32T-SS-IP registers to any SIP 2.0 RFC 3261-compliant platform — Cisco Unified Communications Manager, FreePBX, 3CX, Microsoft Teams Direct Routing via a SBC, and similar environments. The web UI handles extension assignment, dial rules, relay behavior, and codec priority without a dedicated configuration tool. For IP intercom deployments requiring video at the door, evaluate Viking's camera-equipped variants in the same E-32T family. Pair with a PoE network switch to consolidate power and data on a single infrastructure run. For broader access control integration, the relay output wires directly to most electric strikes and mag-lock controllers. See the Viking Electronics product line for companion entry and emergency communication devices.
Frequently Asked Questions
Q: Does the E-32T-SS-IP require a dedicated app or software to configure?
A: No. Configuration is handled entirely through a built-in web UI accessible from any browser on the same network. No proprietary software client is required.
Q: What PoE standard does the E-32T-SS-IP require?
A: It uses PoE Class 2, which draws under 6.5W and is fully compatible with standard IEEE 802.3af switch ports. No PoE+ or 802.3at is needed.
Q: Is the E-32T-SS-IP rated for outdoor installation without an enclosure?
A: Yes. The IP66 rating means it is sealed against dust ingress and high-pressure water jets, making it suitable for direct outdoor mounting. It is not rated for submersion.
Q: What is the operating temperature range?
A: -40°F to 140°F (-40°C to 60°C), covering cold-climate and sun-exposed outdoor installations without supplemental heating.
Q: Can the E-32T-SS-IP control a door strike or gate directly?
A: Yes. It has a built-in programmable relay that can activate a door strike, mag-lock, or gate controller on call answer — no external relay module required for single-door applications.
Q: Does the E-32T-SS-IP support HD audio?
A: Yes. It supports the G.722 wideband codec in addition to G.711u and G.711a. G.722 delivers noticeably clearer voice quality when your PBX and endpoint also support it.
The E-32T-SS-IP is one of the cleaner flush-mount intercom options I have specified for industrial access points — specifically because the 316 stainless faceplate and IP66 rating together handle environments where most intercoms fail within 18 months: coastal facilities, food-processing wash-down zones, and outdoor parking structures in freeze-thaw climates. The -40°F lower operating limit is real, not a marketing footnote.
Technical Highlights:
- PoE Class 2 (<6.5W): Under 6.5W means any 802.3af port powers it — you are not burning a high-wattage port reservation or budgeting for injectors. On a 24-port 370W switch, you can run 50+ of these without hitting the power ceiling.
- G.722 Wideband Audio: Most SIP intercoms ship G.711-only. G.722 support gives you genuine HD voice when your PBX supports it — audible difference on a noisy loading dock where G.711 can sound hollow under ambient HVAC or forklift noise.
- 90 dB SPL at 1 Meter: 90dB is loud enough for most commercial entry environments, but verify against site ambient levels during commissioning — a dock with diesel equipment running at 80–85dBA sustained will reduce effective intelligibility range.
Deployment Considerations:
- The double-gang flush mount requires a standard 2-gang box rough-in — confirm box depth against the 2.25-inch device depth before drywall close-in. Surface-mount option via the VE-Series box avoids the rough-in entirely on retrofit jobs.
- Gel-filled butt connectors are included for wet-location field splices, but the device is not rated for submersion — IP66 covers rain and wash-down, not standing water. Site the unit above grade on exterior walls.
For a pharmaceutical loading dock, a parking garage emergency station, or a coastal marina office entry — anywhere the combination of corrosion resistance, cold tolerance, and SIP registration to an existing PBX matters — the E-32T-SS-IP covers the spec list without requiring supplemental hardware.
