The Reolink G440 is a wireless IP security dome camera that delivers 3840 x 2160 (4K) resolution for clear indoor and outdoor monitoring. Its compact dome design supports flexible placement on ceilings or walls, while wireless connectivity enables remote viewing and simplified installation without extensive cabling. The camera uses a CMOS sensor and offers a wide horizontal field of view of 90° and a vertical field of view of 47°, together with 16x digital zoom for detailed inspection of distant areas.

Advantages

The Reolink G440 provides high-resolution video capture at 4K detail, improving identification and evidence recording. Wireless operation reduces installation complexity and allows versatile positioning. A broad 90° horizontal view covers wide scenes and the 47° vertical angle helps capture higher or lower targets without repositioning the camera. The 16x digital zoom lets users zoom in on areas of interest for closer examination during live view or recorded playback.

How to use

Mount the Reolink G440 on a stable ceiling or wall using appropriate anchors and ensure the camera has a reliable wireless signal from your network. Power the camera according to the manufacturer’s instructions and follow the Reolink app or web setup process to add the camera to your account. Use the app or a compatible NVR system to adjust viewing angle, set recording schedules, configure motion detection zones and access live or recorded footage. Use the 16x digital zoom in live view or playback to inspect areas of interest; remember that digital zoom enlarges pixels and may reduce apparent sharpness compared to optical zoom.

Usage recommendations

Place the camera where the 90° horizontal and 47° vertical view covers the critical area without obstruction, and verify wireless signal strength at the chosen location. For outdoor use choose a sheltered mounting point to protect the unit from direct weather exposure. Configure motion detection sensitivity and recording schedules to balance storage use and event capture, and ensure regular firmware updates via the Reolink app to maintain security and performance.
