Ajax Doorbell Black — 4 MP Wi-Fi IP Video Doorbell with AI

High-resolution access control and video monitoring with the 4 MP Black Ajax Doorbell Smart Video Doorbell

The Ajax Doorbell Black redefines main entrance security for residential and commercial sites by featuring a 4 MP (2560 × 1440 px) camera sensor backed by HDR processing and a sleek, discreet black finish. Built to monitor visitors, couriers, and doorstep activity in crisp detail, it ensures clear facial recognition even under harsh backlight or deep shadows. The device connects via Dual Band Wi-Fi (2.4 GHz and 5 GHz) and utilizes the proprietary JetSparrow protocol for real-time video streaming directly to the Ajax mobile app. It includes a dedicated slot for MicroSD cards up to 256 GB (Class V30 or higher recommended) for standalone local storage, while syncing smoothly with Ajax recorders for continuous video archiving.

On-Chip AI Motion Detection, Two-Way Audio, and Smart Night Illumination

Equipped with a physical PIR sensor paired with chip-level Artificial Intelligence (AI) algorithms, the Doorbell continuously scans the entrance area to sort and classify humans and vehicles, eliminating false alerts triggered by pets or wind-blown vegetation. The two-way audio system with noise and echo cancellation allows crisp, natural conversations with visitors from anywhere via smartphone. For night vision clarity, an integrated smart IR illuminator automatically adjusts power output based on subject proximity up to 5 meters.

Weatherproof IP54 Housing, Interchangeable Covers, and Cloud Security

Engineered for outdoor durability with an IP54 protection rating, the video doorbell connects directly to standard existing chime transformer wiring (12–24 V⎓ or 8–24 V~). It comes with interchangeable front cover plates in multiple colors to blend seamlessly with any exterior door frame. All data transmissions are secured using mTLS Cloud encryption.
