Monitoring system, local host and camera remote preview control method

Abstract

The embodiment of the invention provides a monitoring system, a local host and a camera remote preview control method. The monitoring system comprises a camera, a local host and a remote host. The camera is connected with the local host through a first USB data line, the local host is connected with the remote host through a second USB data line, and the local host receives videos collected by thecamera through the first USB data line and forwards the videos to the remote host through the second USB data line. The camera is connected with the local host through the USB data line, and the local host is connected with the remote host through the other USB data line. The local host receives the video acquired by the camera through the first USB data line and transmits the video to the remotehost through the second USB data line, and the remote host receives the video acquired by the camera through forwarding of the local host, so that preview of the video acquired by the camera by the remote host can be realized.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a monitoring system, a local host and a camera remote preview control method. Background technique [0002] With the popularity of USB (Universal Serial Bus, Universal Serial Bus) devices, at present, video surveillance systems mostly use a connection structure in which the camera is directly connected to the host through a USB data cable. On the host, the camera is recognized as a slave device of the host. , and uses the USB video protocol to realize the functions of controlling and previewing the connected camera. [0003] However, in some special scenarios, due to environmental constraints and other factors, the host that needs to preview the video captured by the camera is often located far away from the camera, and due to the display of the transmission distance, the USB data cable often cannot provide long-distance data transmission. As a result, the video captured by t...

[0003] However, in some special scenarios, due to environmental constraints and other factors, the host that needs to preview the video captured by the camera is often located far away from the camera, and due to the display of the transmission distance, the USB data cable often cannot provide long-distance data transmission. The video captured by the camera cannot be previewed on the remote host
