Ajax DoorBell Grey 4MP AI Video Doorbell with PIR Sensor

Ajax DoorBell Grey - Smart Video Doorbell with Built-In AI and PIR Sensor

The Ajax DoorBell Grey brings professional-grade video verification to the front entrance, blending a wide-angle HDR camera, on-device artificial intelligence and a dedicated PIR motion sensor into one compact, weatherproof unit. Designed to work as a standalone Wi-Fi doorbell or as a fully integrated part of an Ajax security system, it lets homeowners and businesses see, hear and speak with visitors in real time while automatically distinguishing between people, animals and vehicles to cut down on false alerts.

Key Features

• 4MP HDR camera capturing detail up to 2688 x 1520 px with a wide 155° horizontal and 90° vertical field of view, ideal for seeing visitors head-to-toe and parcels left at the door.
• Built-in AI object recognition that automatically classifies motion as a person, animal or vehicle, so notifications stay relevant instead of triggering on every passing shadow.
• Dedicated PIR sensor working alongside the camera's image analysis for faster, more reliable motion detection, even in poor lighting or bad weather.
• Infrared night vision for clear monochrome footage after dark.
• Two-way audio with noise and echo cancellation, plus a loud built-in speaker so conversations at the door stay clear even in noisy outdoor conditions.
• JetSparrow streaming technology, Ajax's proprietary peer-to-peer protocol, for fast, encrypted video loading with minimal lag.
• Dual connectivity via 2.4GHz Wi-Fi as the primary channel, with a backup path over Ajax's Jeweller and Wings radio protocols when paired with an Ajax hub, keeping the doorbell online even if the network drops.
• Flexible video storage options through an Ajax NVR or Ajax Cloud Storage, avoiding the security risk of an on-device SD card.
• Weatherproof IP54 housing in a neutral grey finish, built to handle a wide outdoor temperature range with a backup battery to keep it running through short power outages.

Built for Integrated Home and Business Security

The DoorBell Grey is best suited to homeowners and installers who want a video doorbell that does more than answer notifications. On its own, it delivers sharp video, instant alerts and two-way talk over Wi-Fi. Connected into a wider Ajax ecosystem alongside a hub, keypad and motion detectors, it becomes a networked security camera that can trigger scenarios, provide photo verification for alarm events, and keep working through Wi-Fi outages thanks to its radio backup channel. This makes it a strong fit for both residential entryways and small commercial premises that already run, or plan to run, an Ajax alarm system.

Frequently Asked Questions

Does the DoorBell Grey need an Ajax hub to work?
No. It can operate as a standalone Wi-Fi video doorbell, but connecting it to an Ajax hub adds a radio backup channel and enables photo verification within a full security system.

Can it use an existing doorbell chime?
Yes. The included BellKit adapter is designed to work with standard wired mechanical or digital chimes so households can keep an audible signal alongside app notifications.

Where is footage stored?
Video can be recorded to an Ajax NVR on the local network or archived via Ajax Cloud Storage; the device does not use a local SD card.
