Aiphone GT-1C7W vs Aiphone GT-1A: Specification Comparison
Both the GT-1C7W and GT-1A are Aiphone GT-series tenant stations designed for multi-unit residential and commercial intercom deployments. The GT-1C7W is an audio/video tenant station with mobile app compatibility, while the GT-1A is an audio-only tenant station. A buyer evaluating these is choosing between a video-capable, app-integrated unit and a leaner audio-only alternative within the same GT platform and power architecture.

Does the tenant station support video, and what resolution does it deliver?
The GT-1C7W is specified as an audio/video tenant station with an 8MP camera capable of 4096x2160 resolution, providing tenants with high-definition visual verification of visitors at the door. This capability is reflected in its product tagline and card bullets.
The GT-1A is an audio-only tenant station. No camera, video output, or image resolution is specified for this model. Buyers requiring any video display or capture at the tenant unit must select the GT-1C7W; the GT-1A does not support this function.
Which station offers mobile app integration or remote access for tenants?
The GT-1C7W is explicitly described as app-compatible, with NFC mobile app configuration via smartphone called out in its feature set. This allows tenants to interact with the intercom system through a mobile device, extending functionality beyond the physical station.
The GT-1A has no mobile app compatibility or remote connectivity specified in its provided specs. It operates as a standalone audio intercom terminal. Deployments where tenants need to receive calls or unlock doors remotely via smartphone are outside the GT-1A's documented capabilities.
How do the two stations differ in mounting options, physical footprint, and power sourcing?
The GT-1C7W measures 6.12" x 8.25" x 1.06" and weighs approximately 1.37 lbs (620g). It is surface wall-mount only and draws 24V DC from either a PS-2420UL or GT-4ZP power supply. No desk mount option is specified.
The GT-1A is smaller at 5.3" x 4.7" x 1.6" and lighter at 0.95 lb. It offers greater mounting flexibility—surface mount, 3-gang box, or optional desk mount—and draws 24V DC from the GT-BC power supply. It also supports up to 4 stations per resident location and uses 2-conductor common bus wiring (Aiphone #872002 recommended), with an operating temperature range of 32–104°F (0–40°C). The GT-1A's power source (GT-BC) differs from the GT-1C7W's specified sources (PS-2420UL or GT-4ZP); installers must verify power supply compatibility before mixing units in a single system.
Which should you choose: the GT-1C7W or the GT-1A?
Our take: The GT-1C7W is the stronger choice when tenants require video identification of visitors and mobile app access from their unit. It delivers 8MP / 4096x2160 video versus no video capability on the GT-1A, adds NFC-based smartphone configuration and app compatibility absent from the GT-1A, and weighs 44% more (1.37 lbs vs 0.95 lb) in a larger wall-only footprint. The GT-1A is the appropriate selection for budget-conscious or audio-only deployments where tenants do not need visual verification or remote mobile access: it supports more mounting configurations (wall, 3-gang box, desk), accommodates up to 4 stations per resident location, and specifies a 32–104°F operating range not documented for the GT-1C7W. Both units share the GT platform's 24V DC architecture, but use different specified power supplies—confirm system-level compatibility before combining models.

Frequently Asked Questions
Which should you choose: the GT-1C7W or the GT-1A?
The GT-1C7W is the stronger choice when tenants require video identification of visitors and mobile app access from their unit. It delivers 8MP / 4096x2160 video versus no video capability on the GT-1A, adds NFC-based smartphone configuration and app compatibility absent from the GT-1A, and weighs 44% more (1.37 lbs vs 0.95 lb) in a larger wall-only footprint. The GT-1A is the appropriate selection for budget-conscious or audio-only deployments where tenants do not need visual verification or remote mobile access: it supports more mounting configurations (wall, 3-gang box, desk), accommodates up to 4 stations per resident location, and specifies a 32–104°F operating range not documented for the GT-1C7W. Both units share the GT platform's 24V DC architecture, but use different specified power supplies—confirm system-level compatibility before combining models.
Can I mix GT-1C7W and GT-1A stations in the same GT system?
Both stations operate on 24V DC within the GT platform, but their specified power supplies differ—the GT-1C7W lists the PS-2420UL or GT-4ZP, while the GT-1A lists the GT-BC. The provided specs do not confirm cross-compatibility of these power sources. Consult Aiphone's GT system design guide or technical support before mixing unit types on a single power supply.
Is the GT-1C7W or GT-1A better for larger deployments with multiple stations per apartment?
The GT-1A explicitly supports up to 4 stations per resident location, making it documented for multi-station-per-unit configurations. The GT-1C7W's specs do not state a per-resident station limit. For confirmed multi-station-per-unit requirements, the GT-1A has the clearer specification backing.
Does the GT-1A support video or can it be upgraded to display door camera footage?
No. The GT-1A is specified solely as an audio tenant station. No video display, camera input, or upgrade path to video is documented in its provided specifications. If video at the tenant station is required, the GT-1C7W is the specified option.
