Ajax DoorBell is a video doorbell with built-in AI, PIR motion sensor and app-based control. The device provides high-resolution HDR video (4 MP, 2688 × 1520) and two-way audio, enabling instant communication with visitors. DoorBell supports extended Wi‑Fi range and integrates with Ajax cloud and local storage solutions to ensure recordings remain available even if local media is compromised. The product is designed for easy installation and management through Ajax apps.

Advantages

DoorBell combines AI-powered object recognition and a PIR sensor to reduce false alarms and identify people, animals and vehicles. JetSparrow technology delivers low-latency video streaming so users can view visitors immediately when the bell is pressed. The device works as part of an Ajax security system using Jeweller for alarm notifications and Wings for reliable photo delivery, and it supports ONVIF and RTSP for third-party integration. A built-in backup battery provides up to two hours of operation during power outages, and passwordless mTLS authentication and EU-based data storage ensure secure, compliant data handling.

How to use

Mount the DoorBell using the SmartBracket panel or the included wedge bracket in a location with clear Wi‑Fi reception. Add the device to an Ajax hub through the Ajax app by scanning the QR code and follow the on-screen setup wizard to configure zones, detection sensitivity and notification preferences. Use the app to view live video, speak to visitors, access recorded events from Ajax Cloud Storage or the local archive, and export signed video files when needed.

Recommendations

Place DoorBell at a height and angle that captures approaching visitors and avoids direct sunlight in the camera field of view. Ensure the mounting location maintains a clear line of sight to the Wi‑Fi router for best performance, or integrate the device with an Ajax hub to use Jeweller and Wings communication channels. Regularly check battery status in the app and subscribe to an appropriate Ajax Cloud Storage plan if long-term off-site archive access is required.
