Abstract

An IP camera, a communication method and a communication system are provided. The IP camera includes an image capturing unit, a video processing unit and a connection processing unit. The image capturing unit captures a plurality of consecutive images. The video processing unit is coupled to the image capturing unit, and generates a first video stream and a second video stream according to the images. The connection processing unit is coupled to the video processing unit, processes the first video stream into a first packet stream, and processes the second video stream into a second packet stream. The connection processing unit transmits the first packet stream to a local area wireless network unit through a first wireless link, and the connection processing unit transmits the second packet stream to an external electronic device through a second wireless link.

Claims

1. An IP camera, comprising:

an image capturing unit, capturing a plurality of consecutive images;

a video processing unit, coupled to the image capturing unit, and generating a first video stream and a second video stream according to the images; and
