Recommendations

Install the camera with a protective mount under eaves or an overhang when used outdoors to extend service life. Position the unit to minimize direct exposure to bright light sources to reduce glare and lens flare. Calibrate motion detection sensitivity and recording schedules to balance storage use and event capture. Regularly check firmware updates and perform periodic cleaning of the lens and housing to maintain image quality.
