Ajax Doorbell Video Intercom: Professional Security at the Front Door
DoorBell combines the convenience of an intelligent video door phone with high-end security and video surveillance. When someone presses the video intercom, users can talk to visitors instantly, without delay. Equipped with a PIR sensor and built-in AI, DoorBell accurately detects movement and recognizes humans, animals and vehicles. Users can always get a clear, high-quality view of activity at the front door thanks to the video door phone's wide-range HDR camera.
Immediate access to the video stream in Ajax apps
Users will never keep their guests waiting at the door. Our proprietary JetSparrow technology provides fast video streaming, so users can see visitors in an Ajax app as soon as they press the door phone button. Thanks to DoorBell's excellent image and sound quality, a conversation with guests is almost indistinguishable from a regular phone call.
- Crisp video in 2K thanks to HDR
- Clear voice transmission with noise suppression
- Echo cancellation for improved audibility
Synergy of AI and security for accurate object recognition
The AI-enabled camera detects humans, vehicles, and animals, while the built-in PIR sensor improves detection accuracy and reduces false alarms. By setting detection zones, users receive notifications only when they really matter. For visitors, the device offers a touchless experience. A courier with his hands full does not need to press the button on the video intercom: users are instantly notified of their arrival and can enter the conversation immediately.
Ajax Doorbell always working
DoorBell never becomes a brick, even if Wi-Fi connection is lost. When added to an Ajax hub, DoorBell has a backup communication channel. The device functions as an integral part of an Ajax security system and keeps users and the CRA informed of incidents. DoorBell uses Jeweller secure communication technology to send event and alarm notifications, while the Wings protocol ensures reliable photo delivery.
- Up to 1,700 m of wireless communication2 with an Ajax hub
- Frequency hopping to detect interference or inhibition
- Anti-sabotage tamper to detect device disassembly
Fail-safe protection
If the power in the system fails, DoorBell continues to monitor the situation at the entrance. The built-in backup battery allows the device to remain fully operational for up to two hours after a power failure. When the temperature of the device falls below the optimal range, the battery automatically heats up. This function reduces battery stress, extending battery life and keeping device performance stable.
- Up to 2 hours of autonomous operation
- Automatic battery heating at low temperatures

Extended Wi-Fi range to avoid delays and blockages
Say goodbye to video intercoms that leave the Wi-Fi network at the worst time. Ajax DoorBell is designed to be less susceptible to radio interference and maintain a stable connection up to 500 meters away in line-of-sight, five times farther than competing solutions. The extended range provides greater installation flexibility, as installers no longer have to place the Wi-Fi router directly next to the door. For users, this ensures continuous communication with visitors and uninterrupted streaming when needed.
