Frequently Asked Questions
Yes. The AJAX DoorBell is available in Black, White, Grey, and Graphite finishes, but all colors share identical specifications — 4MP camera, AI object detection, two-way audio, PIR motion detection, and IP54 weather rating. The color is purely a cosmetic choice to match your entrance.
Yes. The DoorBell Grey is rated IP54, which means it’s protected against dust and water spray from any direction. It’s designed for outdoor and indoor installation and handles Melbourne’s weather including rain, humidity, and temperature extremes from −25°C to +60°C.
AI object detection automatically analyzes video frames to identify and classify what’s at your door: people, pets, and vehicles. This reduces false alerts from shadows, leaves, or passing cars, and lets you prioritize notifications based on what matters (e.g., person detected vs. cat detected).
The DoorBell has a built-in microphone and speaker. You can hear and talk to visitors in real-time through the Ajax app on your phone, even when you’re away from home. Built-in noise suppression and echo cancellation ensure clear conversations.
The integrated IR illumination provides visibility up to approximately 6 metres in low-light conditions and complete darkness. The system automatically adjusts IR intensity in real-time to avoid overexposure of nearby objects or washed-out video.
The DoorBell Grey accepts either DC (12–24V) or AC (16–24V, 50/60Hz) power. For optimal operation with a wired chime, a more powerful supply is recommended: DC 12–24V 3A or AC 16–24V 10VA. It includes a rechargeable 600 mAh Li-ion backup battery for approximately 2 hours of backup operation.
Yes. The DoorBell Grey includes a BellKit adapter that allows connection to existing wired chimes. When a visitor presses the button, it triggers both the chime and sends a notification to your phone via the Ajax app.
The package includes the DoorBell unit, SmartBracket mounting panel, 2× wedge brackets for different mounting angles, BellKit for connecting to a wired chime, a complete installation kit with fasteners and tools, and a quick-start guide.
Yes. Professional installation ensures proper mounting height (1.2–1.5m recommended), correct Wi-Fi signal strength, optimal camera angle for your entrance, integration with existing systems, and proper configuration of alert settings. Sipko Security provides complete installation and training for Melbourne customers.
