Aiphone GT-VB 8MP Video Module for GT Modular Entrance Panel
The Aiphone GT-VB is a camera module purpose-built for the GT modular entrance panel system. It captures 8MP resolution using a 1/4" CMOS sensor, delivering a wide 100° vertical by 170° horizontal viewing angle — wide enough to capture visitors head-to-toe and the surrounding entry area in a single frame without requiring the visitor to stand directly in front of the camera. The module is rated IP43, meaning it tolerates spray and dust but is not designed for direct water jets or submersion, making it suitable for covered entry vestibules and recessed door frames rather than fully exposed weather conditions.
Key Features
- 8MP Resolution: Captures fine facial detail and badge information at distance, supporting reliable identification in multi-tenant verification workflows without requiring zoom in post-production.
- 170° Horizontal Viewing Angle: Eliminates blind spots at the entry boundary and reduces the need for additional cameras to cover the approach — saves installation cost and simplifies cabling in modular panel setups.
- Digital Pan-Tilt-Zoom (PTZ) Capability: Allows zoom and repositioning of the live or recorded video stream without moving the camera optics — useful for reviewing entry footage when facial detail is needed at a specific moment.
- 1/4" CMOS Sensor: Compact form factor fits within the modular GT panel frame without requiring a separate housing or auxiliary bracket.
- Microphone Input Supported: Captures two-way audio from the entry point when paired with compatible GT tenant stations and the GT-VBC controller, enabling resident-to-visitor communication without a separate intercom call box.
- IP43 Environmental Rating: Protects against splash and dust ingress; suitable for covered or recessed installations. Upgrade to a higher-rated outdoor camera module if the entrance is fully exposed to rain or high-pressure washdown.
Integration & Compatibility
The GT-VB mounts directly on GT-4F, GF-3F, and GF-2F front frames within the modular panel system. Video output connects via the GT-VBC controller, which supports up to 25 tenants per trunk and 125 total tenants across the system. The module integrates with supported GT series tenant stations including GT-1C7W, GT-1C7, and GT-1M3 displays. Installation requires 2-conductor, solid, non-shielded polyethylene-insulated wiring (Aiphone part #871802 is the recommended specification) to carry video and control signals back to the controller.
If you are expanding an existing GT panel system or replacing a failed video module, confirm your current front frame model (GF-2F, GF-3F, or GT-4F) before ordering — physical mounting compatibility is frame-specific. The modular architecture means you can upgrade video resolution without replacing the entire panel, but the controller and tenant station versions determine feature support for audio and display size.
Deployment Considerations
The GT-VB is a matched accessory for the Aiphone GT entrance system and does not function as a standalone IP camera — it requires the GT modular panel, a compatible tenant station, and the GT-VBC controller to deliver video to residents. If you need IP camera functionality on a generic network (direct RTSP or ONVIF access), choose a standard IP camera instead. For installations where a modular panel is already deployed or planned, the GT-VB eliminates the need for a separate surface-mounted or recessed camera, simplifying the entry point aesthetic and reducing wiring runs.
Frequently Asked Questions
Q: Can I use the GT-VB with the GF-2F, GF-3F, and GT-4F front frames?
A: Yes. The GT-VB mounts directly on all three frame models within the GT modular entrance panel system.
Q: Does the GT-VB provide standalone IP network video, or does it require the GT panel system?
A: The GT-VB is a module for the GT entrance panel only. It does not function as a standalone IP camera and requires the GT-VBC controller and a compatible tenant station to deliver video.
Q: What is the viewing angle, and will it capture a visitor's full face?
A: The GT-VB provides a 100° vertical by 170° horizontal field of view. This width captures the full entry area and approach; most visitors standing at the door will be centered and fully visible, but facial detail depends on distance and lighting.
Q: Is the GT-VB rated for outdoor exposure, or must it be installed in a covered vestibule?
A: The GT-VB is IP43 rated, which tolerates splash and dust but not direct rain jets or submersion. Install it in a covered entry, recessed door frame, or under a soffit. For fully exposed outdoor duty, select a higher IP-rated camera.
Q: Does the GT-VB include a microphone?
A: The GT-VB has a microphone input connector that supports two-way audio when integrated with compatible GT tenant stations and the GT-VBC controller. No external microphone is included; confirm microphone support with your tenant station model.
Q: What wiring is required to connect the GT-VB to the GT-VBC controller?
A: Use 2-conductor, solid, non-shielded polyethylene-insulated wiring. Aiphone part #871802 is the recommended specification for this application.

The Aiphone GT-VB sits at the intersection of modular entrance design and practical video capture — a focused module that delivers what you need without overshooting the application. At 8MP on a 1/4" CMOS sensor with a 170° horizontal angle, the GT-VB does one job well: it captures the full entry zone and visitor detail in a single fixed frame, integrated directly into the modular panel without a separate IP camera license or network binding.
Technical Highlights:
- 8MP Resolution on a 1/4" CMOS Sensor: 8MP from a 1/4" sensor is a compromise between pixel density and low-light performance — you get facial detail sufficient for identification at typical entry distances (3–6 feet), but don't expect sharp recognition at 20 feet or in dark conditions without augmented lighting. The 170° horizontal field of view compensates by capturing the entire approach in one shot.
- Digital Pan-Tilt-Zoom (PTZ): This is a software feature, not optical zoom. You can reposition and magnify recorded or live footage in post-review without moving the camera. Useful for footage review, but don't plan on active tracking or zoom-during-capture — the digital zoom reduces effective resolution as you magnify.
- IP43 Rating: Tolerates splash, spray, and dust ingress but fails under sustained water jets or standing water. Verify that your entry point is under eave cover or recessed at least 12 inches — exposed installations will accumulate water on the lens or seep into the connector, shortening module life.
Deployment Considerations:
- The GT-VB is a locked accessory for the Aiphone GT panel ecosystem — it does not export RTSP, ONVIF, or direct IP video, so you cannot integrate it with a third-party VMS or pull video over the network independent of the GT controller. If you need network video or multi-system integration, use a standard modular entrance panel with IP camera support or pair the panel with a separate standalone IP camera.
- Two-conductor wiring (non-shielded PE insulation) is less robust than twisted-pair Ethernet or shielded video cable — keep runs under 100 feet where possible and avoid routing alongside high-current AC power or motor wiring to prevent interference on the video signal. Aiphone's recommended part #871802 is specified for this voltage and impedance; substituting generic cable invites signal degradation.
Position the GT-VB in modular entrance panel upgrades where residents need reliable visitor identification without a separate smart video doorbell or IP camera system. The tight integration with GT tenant stations and the shared modular frame mean installation is faster and the visual footprint smaller than a recessed or surface-mounted camera — a real win in tight entry vestibules or high-density residential applications where panel real estate is constrained.
