Features: √The HD 1080P Webcam delivers you crystal clear video. The fixed focus computer camera captures high definition video at a wide angle. When you are live streaming, video talking or recording, the HD Webcam will give you an unparalleled perspective for a wide range of situations. √During the operation of the computer web camera, you need to avoid focusing on strong light (such as lighting, sun, etc.), otherwise it will easily cause over-brightness or the blurring light, which will affect the image sensor life (this is not a malfunction of the camera). √Speaking of the installation, you need to ensure that the installation location and the surrounding geomagnetic sensitive equipment maintain a sufficient distance to avoid possible electromagnetic interference. It’s necessary to avoid heat accumulation and keep the ventilation around the camera.
