Indoor station door communication systems are the core interface for voice and video interaction in residential and commercial access control networks. These devices, often referred to as door entry monitors, intercom handsets, or video door phones, integrate a microphone, speaker, and typically a TFT display for visual identification. They operate on low-voltage DC power (e.g., 12-24V) and communicate via 2-wire or 4-wire analog buses, or IP-based protocols for PoE integration. Key technical specs include screen resolution (e.g., 480x320 pixels), audio codec support (G.711, G.729), and flush or surface mounting options with IP30 to IP54 protection ratings.
These units are deployed in multi-tenant apartment buildings, single-family homes, office lobbies, and industrial gatehouses. They connect to outdoor panels via shielded twisted-pair cables or structured cabling (Cat5e/Cat6) for IP systems. In smart building automation, they integrate with KNX, BACnet, or proprietary bus systems to enable remote unlocking, visitor logging, and integration with CCTV or alarm systems. Typical installation environments include distribution boards for power supply and centralized control cabinets for system controllers.
Subcategories include flush-mounted monitors (e.g., model codes starting with "VM-" or "ITV-"), surface-mounted handsets, and touchscreen video stations. Common article codes follow patterns like "VDP-7" for 7-inch video door phones or "IM-4" for 4-inch indoor monitors. These codes often include digits for screen size (e.g., "10" for 10-inch) and suffix letters for color ("W" for white, "B" for black). Accessories like flush-mount boxes and extension modules are listed separately.
