How to use

Install the camera at the chosen location using a compatible mount and ensure the device is weather-protected if installed outdoors. Adjust the lens focal length between 2.8 mm and 12 mm to achieve the required field of view and focus. Connect the camera to the network and configure IP settings, recording schedules and motion or event triggers through the recorder or management software. Verify image framing and adjust exposure and other image parameters as needed for the scene.

Recommendations

For reliable outdoor performance, mount the camera under eaves or use an appropriate housing when exposed to direct weather. When fine detail is required, increase focal length and check focus at the target distance; for broader coverage, set the lens to the wider end. Regularly verify firmware and system integration to maintain compatibility with network video systems.
