Description
The Dahua VTH2621 is a full-digital IP indoor monitor built for compatible Dahua video intercom systems, giving homeowners a clear, touchscreen interface for answering door calls, monitoring cameras, and managing home entry from indoors. Its 7-inch capacitive touchscreen and standard PoE support make it a high-performance, cost-effective choice for villa or apartment intercom setups.
Delivering a 7″ TFT capacitive touchscreen at 1024 x 600 resolution, the Dahua VTH2621 provides a sharp, responsive main interface for answering calls from compatible door stations and navigating the monitor’s full feature set with ease.
Video performance is well handled through H.265 and H.264 video decoding, ensuring efficient, high-quality video playback from connected door stations and IP cameras without placing unnecessary strain on network bandwidth.
Camera monitoring extends the VTH2621’s usefulness beyond a typical intercom handset, letting the screen double as an IPC monitor for viewing compatible IP cameras around the property, giving installers a more complete home security overview from one device.
Network installation is kept simple through standard PoE support alongside a 1 RJ-45 10/100Mbps Ethernet port, letting the monitor receive power and network connectivity through a single cable for straightforward setup.
Alarm integration is comprehensive as well, with 6-channel alarm input and 1-channel alarm output, plus support for floor call functionality using any alarm input port, giving installers room to build a more complete entry and alert system around the device.
Two-way audio communication rounds out the intercom experience, supported through a built-in speaker and audio input, using G.711a, G.711u, and PCM audio compression for clear, reliable voice communication with visitors at the door.
System architecture is capable and efficient, powered by a dual-core 1.2 GHz embedded processor running an Embedded Linux operating system, with 128MB of RAM and 128MB of ROM, plus ONVIF and SDK support for broader interoperability.
Expansion planning is well documented, with Dahua specifying up to 9 extensions for villa configurations and up to 4 for apartment configurations, along with do-not-disturb scheduling and information messaging for flexible household use.
Altogether, the Dahua VTH2621 combines a sharp 7-inch touchscreen, efficient H.265/H.264 video decoding, and simple standard PoE installation, making it a smart, dependable choice for households and installers building a full-digital IP video intercom system.
