Dahua DHI-VTO3311Q-WP IP & Wi-Fi Villa Door Station
The Dahua DHI-VTO3311Q-WP is a robust, surface-mounted IP video intercom for Australian homes, villas, duplexes and small commercial entrances. Its full-metal enclosure combines a 2MP HD camera, ultra-wide 139° diagonal view, 120 dB WDR, two-way audio, IC card access and remote unlocking through a Dahua indoor monitor or the DMSS app.
Connect it by wired Ethernet with standard PoE for maximum stability, or use its built-in 2.4 GHz Wi-Fi where network cabling is difficult. IP65 weather protection, IK08 impact resistance, tamper alarm and a wide −40°C to +60°C operating range make the VTO3311Q-WP a strong choice for exposed Australian entry points.
Replacement for DHI-VTO3211D-P1-S2
Searching for the discontinued Dahua DHI-VTO3211D-P1-S2? The DHI-VTO3311Q-WP is its current replacement model, retaining the familiar 2MP video intercom, IC card access, PoE, IP65 and IK08 capabilities while adding built-in 2.4 GHz Wi-Fi. It is not automatically a drop-in swap: confirm the required call-button layout, mounting, cabling, firmware and compatibility with your existing Dahua indoor monitors before replacement.

Choose PoE Where Possible
For Australian installations, wired Ethernet with PoE is normally the most dependable option. Wi-Fi is available when cabling is impractical, but it uses the 2.4 GHz band only and still requires local power unless PoE is used.
Plan the Complete Intercom
The door station is one part of a working system. Select a compatible Dahua VTH indoor monitor, PoE network connection and suitable electric lock hardware for your entrance and access-control requirements.
