   How It Works

   DoorBell is equipped with a large mechanical button, a camera with IR illumination, an LED indicator, as well as a microphone and speaker for two-way communication. The device allows you to see and speak with a visitor who has pressed the doorbell, as well as monitor the situation at the entrance.

   DoorBell uses a camera with artificial intelligence (AI) support for object recognition. The algorithms can identify moving objects and distinguish between people, animals, and vehicles.

   The device is equipped with smart IR lighting, which ensures high-quality images even in low light. DoorBell automatically adjusts the lighting intensity in real time, preventing overexposure and allowing you to clearly see objects both near and far.

   To save recorded videos, DoorBell must be connected to an Ajax NVR or the cloud archive must be enabled.

   Firmware Update

   If a new firmware version is available for DoorBell, an icon appears on the Devices tab in the Ajax apps.
   An administrator or PRO user with access to system settings can initiate the update via the device’s status or settings. The on-screen instructions will help you successfully complete the update.

   ---

   Working with the Ajax Hub

   The system allows you to configure a backup communication channel so that the device continues to transmit events and alarms even if the Wi-Fi network is down or lost.

   The backup communication channel is enabled by connecting the device to a hub that provides connectivity via the Jeweller and Wings radio protocols. In this mode, the device can transmit alarms, events, and photo verifications, but the live stream and archived recordings will not be available during a Wi-Fi outage.

   When connecting the DoorBell hub, it occupies one device slot.

   ---

   Compatible Hubs and Repeaters

   For the device to work, an Ajax hub with OS Malevich 2.27 or later is required.

   ---

   Jeweller and Wings data transmission protocols

   Jeweller and Wings are wireless data transmission protocols that ensure fast and reliable two-way communication between the hub and devices. DoorBell uses these protocols as a backup communication channel for transmitting events and photos.

   

Choosing an Installation Location

DoorBell is best placed at the entrance to a building or a secured area. This allows visitors to ring the bell, while users can see and communicate with visitors, as well as monitor the situation at the entrance.

The device is designed to be installed at a height of 1.2–1.5 m above the floor. It must be installed on a flat, vertical surface. This ensures a secure mounting and helps prevent false tamper alarms.

Depending on the installation location and height, wedge-shaped brackets can be used to adjust the device's angle. This is necessary to ensure that the motion sensor and camera provide proper coverage.

When choosing a location for the DoorBell, consider the following factors:

• Wi-Fi signal strength.

• Jeweller and Wings signal strength (if the device is connected to a hub).

• The presence of objects or structures that may obstruct the visibility of the device.

Only certified specialists may design and install the system.

Signal strength

Signal strength is determined based on the number of data packets that were not transmitted or were corrupted during a specified time period.

In Ajax apps, on the Devices tab:

• The Wi-Fi signal strength is indicated by the icon.

• The signal strength of the connection to the hub is indicated by the icon.

Signal levels:

• 3 bars — a great signal.

• 2 bars — good signal.

• 1 bar — weak signal; stable performance is not guaranteed.

• Gray icon — no signal.

Do not install the device:

• In locations where the temperature or humidity is outside the permissible limits (this may damage the device).

• In areas where objects or structures obstruct the camera's field of view.

• In areas with a weak or unstable Wi-Fi signal.

• In areas with a weak or unstable Jeweller or Wings signal (when connected to a hub).

• In direct sunlight (this can cause overheating and damage to the electronics).

1. Installation

   Before installing the DoorBell, make sure you have chosen the best location that meets the requirements in this manual.
