Using this Marshall camera is simple. First, make sure you have your own suitable power supply. Connect the camera to your system and use the included remote to control the pan, tilt, and zoom functions. When using, avoid exposing the camera to direct sunlight for long periods as it may affect the image quality. Keep the camera lens clean by using a soft, dry cloth. Regularly check the connections to ensure they are secure. If you have any problems, refer to the camera's user manual or contact customer support.
