An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2.VideoCapture. Usually, RTSP or HTTP protocol is used by the camera to stream video. An example of IP camera streaming URL is as follows: rtsp://192.168.1.64/1 It can be opened with OpenCV like this: capture = … Read more
