Ajax DoorBell smart video doorbell with integrated AI, 4 MP camera and PIR detector

The Ajax DoorBell AJ-DOORBELL-4-GRE combines a smart video doorbell, electronic peephole and outdoor security camera in one compact device for homes, offices and professional access-control projects. It sends mobile alerts, lets users see who is calling and enables real-time two-way communication through the Ajax app.

Designed to work within the Ajax ecosystem, it connects to the Wi-Fi network for video transmission and event notifications. Its 4 MP CMOS camera with HDR, wide viewing angle and IR illumination up to 6 m makes it a practical option for video door entry systems that require remote access management without a complex installation.

The device includes PIR motion detection up to 4 m and AI-based recognition of people, vehicles and animals, according to the manufacturer’s technical sheet. It is intended for new installations, not as a spare part, and is especially suitable for installers working with Ajax security systems, thanks to quick QR-code pairing and mobile configuration.

As an outdoor smart doorbell, the Ajax DoorBell provides access supervision, two-way audio, tamper protection and remote setup from Ajax apps. Please confirm before publishing whether the GRE version should be listed as grey/graphite rather than black.

Practical applications of the Ajax DoorBell smart video doorbell

Example 1. Preventing night-time intrusions and deterring vandalism at a local business:

At two in the morning, a suspicious person approaches the main entrance of a closed retail store with the AJ-DOORBELL-4-B installed outside. The video doorbell’s AI algorithm detects the human silhouette in complete darkness thanks to its infrared LEDs and, before the intruder presses the button, sends a silent motion alert to the owner’s smartphone. The owner opens the app, checks the person’s intentions in 2K video and manually activates the built-in speaker to warn them remotely that the police are on their way, causing the suspect to leave. If the intruder tries to pry the device off with a lever, the internal accelerometer detects the tampering and immediately triggers the store’s siren connected to the Ajax security system.

Example 2. Remote access control for homes and small offices:

In a home, office or professional studio, the Ajax DoorBell works as an electronic peephole and outdoor security camera connected to the Wi-Fi network. When someone rings the doorbell, the user can view live video, identify whether the event involves a person, vehicle or animal, and answer from the mobile app without being physically at the entrance.
