Description

Video monitoring method, video monitoring device and video monitoring system

technical field

The invention relates to the field of video monitoring, in particular to a video monitoring method, a video monitoring device and a video monitoring system in the video monitoring field.

Background technique

Video surveillance is an important part of the security system, and it is a comprehensive system with strong prevention capabilities. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, video surveillance technology has also made great progress.

The preset position and cruise setting are the main means for the camera to cycle through automatically in video surveillance, allowing the camera to cruise within its controllable range. The preset position is an operation mode that links the key area to be monitored with the operating status of the dome camera. When the pan/tilt moves to the place that needs to be monitored, send a command to set the preset point to the ball machine, and the ball machine will record the position of the pan/tilt and the state of the camera at this time, and link it with the number of the preset point . When a call back command is issued to the speed dome camera, the pan/tilt will run to the point at the fastest speed immediately, and the camera will also return to the state of memory at that time, so that it is convenient for the monitoring personnel to quickly check the monitored area. The so-called cruise means that the camera patrols among the preset positions according to the set time and preset sequence.

At present, when users set preset positions or cruise settings, they need to constantly adjust the rotation angle and focal length of the speed dome until they find the area they want to monitor and the specific picture they want to present. This operation method is inefficient, and requires the user to be particularly familiar with the imaging range of the camera, resulting in poor user experience.

In addition, through one-time recording operation, the camera can remember the action of this operation, remember the position, action, and time passed, so as to set the preset position or cruise. However, this operation method also requires the user to be particularly familiar with the camera’s shooting range and have an overview map in mind, otherwise the user will feel confused and unable to set up, and the user experience will be poor; The camera angle and time are wrong, which reduces the effectiveness of monitoring.
