Product SKU: DHI-VTO2111D-P-S2
Product Overview
Built for villa-style residential entry and small commercial gate access, the Dahua DHI-VTO2111D-P-S2 is a surface-mount IP door station combining a 1MP wide-angle camera with two-way audio, card reader access control, and PoE power delivery in a compact black unit. Featuring a 107-degree horizontal field of view, 120dB WDR, and auto IR day/night switching, it captures clear facial and scene detail across a broad entry approach even in high-contrast lighting conditions. Equipped with a built-in microphone and speaker, it supports real-time two-way voice communication with a connected indoor monitor. It also integrates an access card reader supporting up to 10,000 cards, controls two independent locks, and includes 2 alarm inputs alongside an RS485 interface. This makes it well suited to gated villa entries, townhouse complexes, and small office foyers where a single streamlined station manages both video intercom and door access from one surface-mounted unit.
Key Capabilities
1MP Wide-Angle Entry Camera
A 1/4-inch 1MP sensor with a 107-degree horizontal field of view captures the full entry approach, including faces and surrounding context at a gate or door. Auto IR switching and 120dB WDR handle backlit conditions common at building entrances.
Confirmed Two-Way Voice Communication
A built-in microphone and speaker enable real-time two-way voice calls between the door station and a paired indoor monitor. Echo suppression, echo cancellation, and digital noise reduction keep audio clear at outdoor entry points where ambient noise is a factor.
Integrated Card Reader – Up to 10,000 Cards
The onboard card reader supports up to 10,000 access credentials, allowing residents or staff to present a card for entry without needing to call the indoor station. This suits multi-resident villa complexes or small offices where keyed access is being replaced with card-based control.
Dual Lock Output Control
The DHI-VTO2111D-P-S2 controls 2 independent lock outputs, allowing a single door station to manage both a pedestrian gate and a vehicle gate, or a main entry and a secondary door, without requiring a separate access controller for each.
PoE Power and Surface-Mount Installation
Standard PoE eliminates the need for a local power supply at the door, simplifying cable routing to a single Cat5e or Cat6 run. The surface-mount form factor suits walls, pillars, and post-mounted enclosures without requiring a flush back-box.
IP65 Weather Protection and MicroSD Local Storage
An IP65 rating provides protection against dust ingress and directed water spray, making the station suitable for covered outdoor entry positions. A MicroSD slot supports up to 32GB of local snapshot and video storage, useful for audit trails independent of the network recorder.
Best For
- Villa and Gated Residential Entry: The surface-mount design, single call button, and 107-degree wide-angle lens suit a pillar or wall-mounted position at a single-residence or small complex gate.
- Card-Based Access Without a Separate Controller: The integrated card reader handling up to 10,000 credentials replaces the need for a standalone access controller at entries where card swipe is the primary method of entry.
- Dual-Gate or Two-Door Sites: Sites needing independent control of 2 lock outputs from a single door station, such as a pedestrian gate and vehicle gate, benefit from the built-in dual lock output without additional hardware.
- PoE Network Intercom Deployments: Installers running structured cabling to entry points can power and connect the station over a single Cat cable, keeping the installation tidy and avoiding separate power runs to external locations.
Why Choose the DHI-VTO2111D-P-S2
The DHI-VTO2111D-P-S2 consolidates video intercom, card-based access control, and dual lock output management into a single surface-mount unit that draws power directly from a PoE switch. A simpler door station would require a separate access controller to handle card credentials and lock outputs, adding cost and cabling complexity. The 120dB WDR performance addresses the backlit entry approach problem common at gates and building fronts, where morning and afternoon sun behind a visitor would otherwise wash out the image. With audio echo cancellation built in, the two-way call quality remains usable even in open outdoor environments. Local MicroSD storage means snapshot records are retained even if the network recorder is temporarily unavailable. Available at Security Wholesalers, the DHI-VTO2111D-P-S2 suits integrators and property managers looking to deploy a capable IP villa station without specifying multiple devices for a single entry point.
Buyer Decision Tips
Pairing with an Indoor Monitor: The DHI-VTO2111D-P-S2 is a door station only and requires a compatible Dahua VTH indoor monitor to complete the intercom call path. Confirm the indoor monitor model is compatible with the VTO2111D-P-S2 before ordering, and check whether the deployment needs a VMS or DSS server for multi-apartment configurations, as this station targets single-villa or small-complex use rather than large multi-tenant buildings.
IP65 Sealant Requirement: The IP65 rating is conditional. Dahua’s datasheet explicitly states that silicone sealant must be applied during installation as described in the quick start guide. Skipping this step reduces weather resistance at cable entry and mounting points. This is particularly important for stations exposed to driving rain or high-pressure cleaning near the entry area.

Ideal Use Cases
Single-Residence Villa Gate
The single call button, 107-degree wide-angle lens, and surface-mount housing suit a wall or pillar position at a villa entry gate, giving the homeowner a clear view of the visitor and a direct two-way voice call to the indoor monitor before releasing the lock.
Small Residential Complex Entry
With the card reader supporting up to 10,000 credentials, a small townhouse or villa complex can issue cards to all residents for keyless entry without installing a separate access controller at the gate.
Dual-Gate Vehicle and Pedestrian Control
The 2 independent lock outputs allow a single DHI-VTO2111D-P-S2 installation to control both a pedestrian door and a vehicle gate separately, reducing hardware and cabling at sites where two access points share the same entry approach.
Small Office or Studio Entry
A small office or studio reception with a single front door benefits from the combined intercom call and card access in one surface-mount device, allowing staff to use a card and visitors to call through to a desk monitor, without requiring two separate systems.
Covered Outdoor Entry in Harsh Conditions
With an operating temperature range of -30°C to +60°C and IP65 weather protection, the station handles exposed entry positions in climates ranging from cold winters to hot Australian summers, provided sealant is applied correctly during installation.
Choosing the Right Model
- Choose this model if: You need a single surface-mount door station that handles video intercom, card access for up to 10,000 users, and control of 2 lock outputs from one device, powered over a single PoE cable with no local power supply required at the door.
- Choose a different model if: Your installation is a multi-apartment building with many independent tenants each requiring their own call button and apartment number directory, as that scenario requires a multi-button or modular door station designed for apartment block configurations rather than a single-button villa station.
- Choose a different model if: You need a flush-recessed installation into a finished wall or post where a surface-mount profile would be visually unsuitable, as this unit is designed specifically for surface mounting.
FAQs
- Does the DHI-VTO2111D-P-S2 work as a standalone device or does it need an indoor monitor?
The DHI-VTO2111D-P-S2 is a door station only. It requires a compatible Dahua VTH indoor monitor (sold separately) to complete the two-way intercom call path. The door station handles camera, audio, card reading, and lock output, but the call is answered at the indoor monitor. Confirm compatibility between the VTO and VTH models before purchasing.
- Is the IP65 rating guaranteed out of the box, or does installation affect it?
The IP65 rating is conditional on correct installation. Dahua’s official datasheet states that silicone sealant must be applied at cable entry and mounting points as described in the quick start guide. Without sealant, the ingress protection is not maintained. This step must not be skipped, particularly on stations exposed to rain or cleaning water.
- What type of access cards does the integrated card reader support?
The datasheet confirms the card reader supports up to 10,000 cards, but does not specify the card technology (such as Mifare or EM) in the data provided. Check the full Dahua product documentation or contact your supplier to confirm which card format is compatible before purchasing access cards or fobs for your site.
- Can the station control a gate motor directly, or is a separate relay required?
The DHI-VTO2111D-P-S2 provides 2 lock output interfaces. Whether these connect directly to a gate motor controller or require an intermediate relay depends on the voltage and current requirements of the specific gate motor. Most gate motor controllers accept a dry contact signal, which the lock output can provide, but verify the gate motor’s input requirements against the door station’s output specs before wiring.
- How does the 120dB WDR help at an entry gate?
Entry gates commonly have strong backlighting, particularly in the morning and late afternoon when the sun is low and behind the visitor. Without WDR, the camera would expose for the background and leave the visitor’s face as a dark silhouette. The 120dB WDR on the DHI-VTO2111D-P-S2 balances bright sky and shadow in the same frame, producing a recognisable face image in those high-contrast conditions.
- What does the MicroSD card slot store, and is it required for basic operation?
The MicroSD slot (up to 32GB) stores local snapshots and video triggered by motion detection or visitor calls. It is not required for basic intercom and door release operation, but it provides an independent audit trail of entry events that remains available even if the network recorder is offline or not installed on the site.
- Where can I purchase the DHI-VTO2111D-P-S2 and get technical support for the installation?
The DHI-VTO2111D-P-S2 is part of the Security Wholesalers range. For technical queries about compatible indoor monitors, cabling requirements, or network configuration, contact the Security Wholesalers team directly. Having the full site plan including cable run lengths, number of indoor monitors, and lock types on hand will help resolve compatibility questions quickly.
Cabling Considerations
- Cable Type: Cat5e or Cat6 UTP or STP for PoE power and network data. Use STP in environments with electrical interference such as near gate motors, lighting controllers, or industrial equipment.
- Maximum Cable Run: Standard PoE over Cat5e or Cat6 supports up to 100 metres from the PoE switch to the door station. For longer runs, a PoE extender or a local 12V DC power supply at the door is required.
- PoE Considerations: The station draws a maximum of 5W during active use, which falls within the Class 1 PoE budget. Any 802.3af PoE switch or injector is sufficient. No high-power PoE+ equipment is required.
- Lock Output Wiring: Two separate lock output runs are required if both outputs are being used. Use appropriately rated cable for the lock type. Confirm the lock’s current draw does not exceed the door station’s output rating.
- RS485 Wiring: If connecting external RS485 devices such as a card reader expander or third-party controller, use twisted-pair cable with a characteristic impedance of 120 ohms and terminate the bus correctly to avoid signal reflections on longer runs.
- Sealant and Cable Entry: All cable entry points must be sealed with silicone sealant as specified in the Dahua quick start guide. Failure to do so will compromise the IP65 weather protection rating at those points.
