Problems solved by technology
[0004] In the related technology, in the process of controlling the camera, the network keyboard not only needs to send commands frequently, but also needs to fetch streams at the same time. However, the resources of the network keyboard are limited, which leads to a large resource consumption of the network keyboard, resulting in network delays and freezes. and other phenomena

Embodiment Construction
[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.
[0056] Currently, cameras are widely used in the security field. For example, the network keyboard is used to control the rotation of the camera for multi-directional monitoring, and to control the zoom and zoom of the camera to collect clear images. In the embodiment of the present application, the camera may be various types of movable cameras, such as a dome camera. In the process of using the network keyboard to control the camera, in the related art, the network keyboard in the process of controlling the camera takes real-time streams and previews the video collected by the camera. However, due to the limited resources of the network keyboard, it is necessary to frequently send control commands to the device. I...

The invention discloses a camera control method, a device, a system and equipment, and belongs to the technical field of security and protection. In the embodiment of the invention, a server receives a control command of a network keyboard, and a preview command is sent to a client which logs in the server with the same user name through the server, so that a camera controlled by the network keyboard is controlled through the client to send a stream to the client, and the client obtains and displays a video collected by the camera. Therefore, according to the scheme, the network keyboard is prevented from taking the stream from the camera, so that the resource consumption of the network keyboard can be reduced, the jamming phenomenon when the network keyboard controls the camera is reduced, and the network time delay is reduced.
Description
technical field [0001] The embodiments of the present application relate to the field of security technologies, and in particular to a camera control method, device, system, and equipment. Background technique [0002] Currently, cameras are widely used in the security field. For example, control the rotation of the camera through the network keyboard for multi-directional monitoring, control the zoom and zoom of the camera to capture clear images, and display the video captured by the camera when operating the camera through the network keyboard, so as to show it to the operator for easy operation Personnel observe changes in video content. [0003] In the related technology, the video captured by the camera is obtained and displayed by the network keyboard during the process of controlling the camera. Among them, the operator operates the network keyboard to send commands to the camera or NVR (Network Video Recorder, Network Video Recorder) to control the camera to perfo...
