Ajax Systems DoorBell, 4 MP Camera with built-in AI and PIR Sensor

The images can only be stored on the AJAX NVR or in the AJAX Cloud.

Professional security at the front door
DoorBell combines the convenience of a smart doorbell with high-end security and video surveillance. When someone rings the doorbell, the user speaks directly to the visitor, without delays . Equipped with a PIR sensor and built-in AI , DoorBell accurately detects motion and recognizes people, animals and vehicles. Users can always get a clear view of what is happening at the front door, all in excellent quality thanks to the doorbell's long-range HDR camera.

Direct access to the video stream in Ajax apps
Users will never have to leave their guests waiting at the door again. This patented JetSparrow technology provides fast video streaming, so users can see their visitors in an Ajax app as soon as they ring the doorbell. Thanks to DoorBell’s excellent image and sound quality, answering the door has never been so close to a simple phone call.

Synergy of AI and security for accurate object recognition
The DoorBell’s AI-powered camera detects people, vehicles, and animals, while a built-in PIR sensor improves detection accuracy and reduces false positives. By setting detection zones, users only receive notifications when it matters most. For visitors, the device offers a contactless experience. A delivery person with their hands full doesn’t have to press the doorbell button: users are instantly notified of their arrival and can join the conversation right away.

Always on guard
DoorBell never turns into a brick, even if the Wi-Fi connection drops. When added to an Ajax hub, DoorBell has a fallback communication channel. The device works as a full-fledged part of an Ajax security system, keeping users and the CMS informed of events on site. DoorBell uses Jeweller secure communication technology to send event and alarm notifications, while Wings protocol ensures reliable photo delivery.
