PRODUCT DETAILS

The Ajax DoorBell combines the convenience of a smart doorbell with high-end security and video surveillance. When someone rings the doorbell, the user talks to the visitor straight away, with no lags or delays. Equipped with a PIR sensor and built-in AI, DoorBell accurately detects movement and recognizes people, animals, and vehicles. Users can always get a clear view of what is happening at the front door, all in outstanding quality thanks to the doorbell’s wide-range HDR camera.

The Doorbell can be used as a standalone device, but it’s designed to integrate seamlessly into the larger Ajax security system. You can pair it with the Ajax Hub for expanded functionality, such as receiving notifications through the Ajax app or using it in conjunction with other Ajax devices (like cameras or alarms).


Instant access to the video stream in Ajax apps

Users will never keep their guests waiting at the door. The Ajax proprietary JetSparrow technology provides speedy video streaming so users can see their visitors in an Ajax app as soon as they ring the doorbell. Thanks to DoorBell’s superb picture and audio 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 enhances detection accuracy and reduces false positives. By setting up detection zones, users receive notifications only when it truly matters. For visitors, the device offers a touchless experience. A courier with full hands doesn’t need to press the doorbell button: users are instantly notified of their arrival and can jump into the conversation immediately.


Standing guard at all times

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


Extended Wi-Fi range for no lags and freezes

Forget about the video doorbell dropping off the Wi-Fi network at the worst possible moment. DoorBell is designed to be less susceptible to radio interference and maintain a stable connection at up to 500 meters in line of sight — five times farther than competing solutions. This extended range offers greater installation flexibility, as installers no longer need to position the Wi-Fi router directly near the door. For users, it ensures seamless communication with visitors and uninterrupted streaming whenever needed.
