Aiphone GT-1C7 vs Aiphone GT-1A: Specification Comparison
Both the GT-1C7 and GT-1A are Aiphone GT-series tenant stations designed for multi-unit residential or commercial intercom deployments. They share the same communication modes and wiring standard but diverge sharply in capability: the GT-1C7 adds a 7-inch LCD display and 8MP video capture, while the GT-1A is a pure-audio station. Buyers comparing these are typically deciding whether residents in a given unit need visual confirmation of visitors or whether audio-only intercom coverage is sufficient for their budget and installation design.

Does the tenant station provide video identification or audio-only communication?
The GT-1C7 is a video tenant station equipped with a 7-inch LCD display and 8MP image capture at 4096×2160 resolution, enabling residents to visually screen visitors before granting access. These specs are explicitly listed in the product data.
The GT-1A provides no display and no video capability. Its spec set contains no mention of a screen, camera input, or image capture. It is an audio-only tenant station, delivering two-way voice communication via microphone-supported, hands-free VOX or push-to-talk simplex modes — identical communication modes to the GT-1C7, but without any visual component.
For deployments where visitor identification at the door is a security or compliance requirement, only the GT-1C7 satisfies that need. The GT-1A is appropriate where audio intercom alone is acceptable or where a shared video display is provided elsewhere in the system.
How do the physical form factors, mounting options, and wiring requirements compare?
Both units are wall-mount devices using 2-conductor, solid, unshielded common-bus wiring — consistent with the GT-series architecture. The GT-1A explicitly supports 3-gang box mounting as well as flat-surface and optional desk mounting, giving installers more placement flexibility. Its dimensions are specified at 5.3 × 4.7 × 1.6 in and it weighs 0.95 lb.
The GT-1C7 is heavier at approximately 1.25 lb (570 g), consistent with the addition of a 7-inch LCD panel. Its mounting options are listed only as wall mount; 3-gang box or desk mount options are not stated in the provided specs. Installers should verify rough-in requirements for the GT-1C7 against Aiphone documentation before committing to a box type.
The GT-1A's wiring note recommends Aiphone cable #872002 and supports up to 4 stations per resident location, which is a capacity figure not provided for the GT-1C7. Neither spec lists maximum cable run distance.
What are the power requirements and environmental operating limits for each station?
The GT-1A specifies 24V DC power supplied from the GT-BC power supply. This is a clear, installer-actionable spec confirming the power source and voltage.
The GT-1C7 specs provided do not state a power supply voltage or source. Installers must consult the GT-1C7 datasheet (referenced at /content/product-datasheets/GT-1C7.pdf) to confirm power requirements before design.
Operating temperature is specified only for the GT-1A: 32–104°F (0–40°C), a standard indoor range. No operating temperature is listed for the GT-1C7 in the provided specs. Country of origin is listed for the GT-1A (Vietnam) but not for the GT-1C7. Both carry a 2-year warranty.
Which should you choose: the GT-1C7 or the GT-1A?
Our take: The GT-1C7 is the stronger choice when residents require visual confirmation of visitors, as it is the only unit of the two that provides a 7-inch LCD display and 8MP video capture at 4096×2160 resolution — the GT-1A offers zero video capability. Against that, the GT-1A is lighter (0.95 lb vs 1.25 lb), specifies a broader set of mounting options (3-gang box, flat surface, desk) compared to wall-only for the GT-1C7, and explicitly supports up to 4 stations per resident location with a documented 24V DC power source from the GT-BC — neither of those figures is confirmed in the GT-1C7 specs provided. Choose the GT-1C7 for tenant locations requiring on-screen visitor screening; choose the GT-1A for audio-only resident coverage or secondary stations within a resident suite where a primary video station already exists.

Frequently Asked Questions
Which should you choose: the GT-1C7 or the GT-1A?
The GT-1C7 is the stronger choice when residents require visual confirmation of visitors, as it is the only unit of the two that provides a 7-inch LCD display and 8MP video capture at 4096×2160 resolution — the GT-1A offers zero video capability. Against that, the GT-1A is lighter (0.95 lb vs 1.25 lb), specifies a broader set of mounting options (3-gang box, flat surface, desk) compared to wall-only for the GT-1C7, and explicitly supports up to 4 stations per resident location with a documented 24V DC power source from the GT-BC — neither of those figures is confirmed in the GT-1C7 specs provided. Choose the GT-1C7 for tenant locations requiring on-screen visitor screening; choose the GT-1A for audio-only resident coverage or secondary stations within a resident suite where a primary video station already exists.
Can the GT-1A display who is at the door, or do I need the GT-1C7 for that?
You need the GT-1C7. The GT-1A is an audio-only tenant station with no display and no video input. The GT-1C7 provides a 7-inch LCD and 8MP capture at 4096×2160 for visual visitor identification. The GT-1A provides microphone-supported, hands-free VOX or push-to-talk audio only.
Can I install multiple GT-1A stations at a single tenant location?
The GT-1A specs state a capacity of up to 4 stations per resident location. No equivalent multi-station capacity figure is provided in the GT-1C7 specs, so that should be confirmed with Aiphone documentation before designing a multi-station video layout.
Do both stations use the same wiring and connect to the same GT-series system?
Both use 2-conductor solid unshielded common-bus wiring consistent with the GT-series platform, and both support hands-free VOX and push-to-talk simplex communication modes. The GT-1A recommends Aiphone cable #872002 specifically. Both carry a 2-year warranty. Power supply compatibility for the GT-1C7 should be verified against its datasheet, as voltage is not stated in the provided specs.
