Door phones, also known as intercom systems or entry phones, are communication devices installed at building entrances to facilitate two-way audio (and often video) interaction between visitors and occupants. These systems typically consist of an outdoor station with a call button, microphone, and speaker, and an indoor station for response. Technical specifications include power supply voltage (e.g., 12V DC or 24V AC), wiring type (2-wire or 4-wire for analog systems, or PoE for IP-based units), and IP rating for outdoor units (e.g., IP54 or IP65 for weather resistance). Some models support hands-free operation, call forwarding to mobile devices, and integration with access control systems like magnetic locks or electric strikes.
Door phones are widely used in residential buildings, apartment complexes, office blocks, and industrial facilities to control entry and enhance security. They are installed in entrance lobbies, gates, or perimeter doors, often integrated with CCTV systems, video doorbells, or building management systems (BMS). In commercial settings, they enable secure visitor management, while in industrial environments, they provide communication at restricted access points. The systems can be surface-mounted or flush-mounted, depending on the wall construction and aesthetic requirements.
Key subcategories include analog door phones, IP door phones, video door phones, and wireless intercoms. Common article codes follow patterns like DP-2000 for analog units or IPDP-1000 for IP-based models. For example, the DP-2000 series offers 2-wire analog communication with a 12V DC supply, while the IPDP-1000 series supports PoE and SIP protocol for integration with VoIP networks. Video door phones often include a CMOS camera with IR LEDs for night vision, and some models feature a 7-inch color LCD screen at the indoor station.
