Product SKU: DHI-VTO2211G-WP-S2
Product Overview
The Dahua DHI-VTO2211G-WP-S2 is a 2MP IP and Wi-Fi villa door station designed for homes, townhouses, offices and controlled pedestrian entrances. Its 1/2.8-inch camera provides a wide 125° horizontal view, 120dB WDR and automatic infrared illumination to capture visitors standing close to the doorway across changing light conditions. The single-button station supports two-way audio, app calling, automatic snapshots and unlocking through an IC card, compatible indoor monitor or mobile app. Its integrated reader stores up to 10,000 cards, while Ethernet, 2.4GHz Wi-Fi, standard PoE and 12V DC provide flexible installation options. Dahua also lists support for controlling two locks, with one lock channel dependent on a compatible secure control arrangement. IP65 protection suits properly sealed outdoor surface mounting. Indoor monitors, electric locks, storage media and any required secure control equipment must be selected separately.
Key Capabilities
Wide 2MP Entrance Camera
The camera provides a 125° horizontal, 71° vertical and 142° diagonal field of view. This helps capture visitors positioned close to the doorway or slightly off-centre rather than only those standing directly in front of the station.
Two-Way Audio and App Calling
The integrated microphone, built-in speaker, echo suppression and digital noise reduction support conversations with visitors. Compatible app integration allows configured users to receive calls and remotely unlock the entrance from a mobile device.
Built-In IC Card Reader
The integrated reader supports local card enrolment and stores up to 10,000 IC cards. Its listed reading distance of up to approximately 4.3cm suits convenient credential-based entry for residents, staff and authorised visitors.
Dual-Lock System Support
Dahua lists support for controlling two locks, with one lock channel using a compatible secure control arrangement. The station also provides an exit-button input, door-status input, RS-485 and alarm interfaces for a more complete entrance design.
Ethernet, Wi-Fi and PoE
A 10/100Mbps Ethernet port and 2.4GHz Wi-Fi provide network flexibility, while standard PoE or a 12V DC supply can power the station. Wi-Fi still requires a suitable local power source and reliable signal coverage.
Outdoor IP65 Protection
The surface-mounted housing is rated IP65 and operates from -30°C to +60°C. Dahua specifies silicone sealant for the IP65 installation, making correct cable sealing and weatherproof mounting essential.
Best For
- Homes and Townhouses: Provides video calling, card access and remote unlocking at a main pedestrian entrance.
- Gated Driveways: Suits a pedestrian gate requiring a wide visitor view and control of one or two compatible locks.
- Small Offices: Allows staff to answer entrance calls and issue IC cards to authorised users.
- Clinics and Professional Suites: Supports controlled visitor entry through an indoor monitor or configured mobile app.
- Wi-Fi Intercom Installations: Provides wireless network connectivity where a wired Ethernet data connection is inconvenient.
Why Choose the DHI-VTO2211G-WP-S2
The DHI-VTO2211G-WP-S2 combines visitor calling, credential access and door control in a compact single-button station. Compared with a basic video doorbell, it provides a 10,000-card capacity, RS-485, alarm interfaces, door-status monitoring and support for a second lock through a compatible secure control arrangement. Its wide 2MP camera, 120dB WDR and infrared illumination suit close doorway coverage, while Ethernet, Wi-Fi, PoE and 12V DC options provide flexibility across new installations and selected upgrades. Available through Security Wholesalers, this model is best planned as part of a complete Dahua intercom system. Buyers should confirm the indoor monitor, mobile-app setup, lock power, secure control requirements and weather sealing before installation.
Buyer Decision Tips
Dual-Lock Tip: The station lists one normally closed onboard lock-control port while overall product support covers two locks. Confirm the compatible secure control arrangement and separate lock power requirements before wiring a second entrance device.
Wi-Fi and Weather Tip: Wi-Fi carries network data but does not power the station. Check 2.4GHz signal strength at the entrance and apply the required silicone sealant and cable-junction protection to achieve the intended IP65 installation.

Choosing the Right Model
- Choose this model if: The entrance needs one call button, Wi-Fi, card access, app communication and support for up to two locks.
- Choose a keypad model if: Visitors or staff need PIN-code access without carrying an IC card.
- Choose a multi-button station if: Separate physical call destinations are required for several residences or offices.
- Confirm the secure control arrangement if: Two electric locks must be operated from the same entrance system.
- Choose wired Ethernet if: The entrance has unreliable 2.4GHz Wi-Fi coverage or requires the most stable network connection.
FAQs
- Is the DHI-VTO2211G-WP-S2 a complete villa door station?
The DHI-VTO2211G-WP-S2 is a complete single-button IP villa door station rather than an expansion module. It includes a 2MP camera, built-in microphone and speaker, IC card reader, network connection and door-control interfaces. A compatible indoor monitor, electric lock, exit button, power equipment and any secure control module must be selected separately according to the final entrance design.
- How wide is the camera view on the VTO2211G-WP-S2?
The 1/2.8-inch 2MP camera provides a 125° horizontal, 71° vertical and 142° diagonal field of view. This is suited to close entrance coverage where a visitor may stand slightly to one side of the doorway. The camera also supports 120dB WDR, automatic infrared illumination and day or night switching to improve visibility across changing entrance conditions.
- Can this villa door station connect through Wi-Fi?
Yes. The VTO2211G-WP-S2 supports 2.4GHz Wi-Fi under IEEE 802.11b/g/n, as well as a 10/100Mbps Ethernet connection. Wi-Fi carries network data but does not remove the need for power. The unit must still be powered through standard PoE or a suitable 12V DC, 1A supply, and wireless signal strength should be checked at the entrance before installation.
- How does the built-in card reader work?
The integrated reader supports IC cards, local card enrolment and a listed capacity of up to 10,000 cards. The specified reading distance is approximately 0 to 4.3cm. Cards can be used as one of the supported unlocking methods alongside the indoor monitor and mobile app. The correct card type and access permissions must be configured before credentials are issued to users.
- Can the DHI-VTO2211G-WP-S2 control two electric locks?
Yes. Dahua lists support for controlling two locks, with the product key points indicating that one channel uses a secure control module. The door station itself lists one normally closed lock-control port, together with an exit-button input, door-status input, RS-485, alarm input, alarm output and a 12V, 200mA power output. Lock power and compatibility must be designed separately.
- Does the VTO2211G-WP-S2 support two-way audio and mobile app calls?
Yes. The door station supports two-way audio with an audio input, built-in speaker, echo suppression and digital noise reduction. It can place voice calls through the compatible intercom system and supports app communication through a configured Dahua platform. Call performance depends on the network, internet connection, mobile notification settings and correct registration of the door station and indoor monitor.
- Can the door station save visitor videos?
Yes. The VTO2211G-WP-S2 supports automatic snapshots and visitor video messages when a suitable microSD card is installed in the door station or compatible indoor monitor. The door station supports a microSD card up to 256GB. Storage media is not stated as included, and recording behaviour or retention depends on the configured intercom system and available storage capacity.
- Is the VTO2211G-WP-S2 suitable for outdoor installation?
Yes. The unit is rated IP65 and operates from -30°C to +60°C at 10%–90% non-condensing humidity. Dahua specifies that silicone sealant is required for the IP65 installation, and its anti-corrosion level is listed as basic protection. When planning through Security Wholesalers, confirm the mounting surface, rain exposure, cable sealing, lock arrangement and required indoor monitor before installation.
