What our Experts Think

• Multi-user entry made for shared spaces
  The 2-call-button configuration is designed for duplex homes, small offices, or multi-tenant entrances—allowing separate, direct calling from a single door station.
• Reliable smart access control system
  Includes RFID reader, configurable relays, and app-based control, making it suitable for structured access management and integration into professional security setups.
• Wide-angle video with strong coverage
  The ultra-wide 180° lens with night vision ensures full visibility of visitors and entry areas, reducing blind spots at the doorway.
• Designed for smart integration
  Supports PoE (LAN), SIP, and open API connectivity, enabling integration with smart home platforms, intercom systems, and building automation tools.
• Advanced motion detection intelligence
  Built-in 4D motion sensor (adjustable range up to ~10 m) improves detection accuracy and enables automation triggers like alerts or lighting control.
• Flexible installation options
  Supports both flush and surface mounting (housing dependent), making it adaptable to new builds and retrofit projects.
• Expert verdict
  A high-performance IP video intercom built for multi-user entrances, combining reliable video security, smart access control, and strong integration flexibility—best suited for shared residential or small commercial entry points where dual calling is essential.

Q&A

Maintenance Tips

• Clean front panel & camera regularly: Wipe the 720p ultra-wide lens, microphone, and call buttons with a soft microfiber cloth to maintain clear video and reliable input. Avoid harsh or alcohol-based cleaners.
• Maintain call buttons & nameplates: Ensure both call buttons remain free of dust, dirt, and moisture buildup for accurate triggering in multi-user setups (duplex or small offices).
• Keep network connection stable (PoE/LAN): Use a reliable Ethernet/PoE connection for uninterrupted 2-way audio, live video, and remote access via the DoorBird app.
• Update firmware & mobile app: Regular updates improve security, fix bugs, and enhance smart home integration and call reliability.
• Inspect seals & mounting housing: Check flush or surface-mounted housing for tight sealing to prevent water ingress and weather damage.
• Optimize motion sensor & night vision: Keep the sensor area clean and unobstructed for accurate detection and clear IR night vision performance.
• Check relays & door control functions: Periodically test both switching relays (door/gate control) to ensure smooth remote unlocking functionality.
• Weather inspection routine: After heavy rain, dust, or extreme temperatures, inspect the unit for debris, condensation, or physical wear.
• Power stability check: Ensure consistent PoE or DC power supply to avoid call failures or intermittent connectivity issues.
