Control method and device for improving storage stability in video monitoring system

Abstract

The invention provides a control method for improving storage stability in a video monitoring system. The control method is used for ensuring that a video shot by an Internet protocol (IP) camera can be integrally stored into a storage device managed by a control platform. The method comprises the following steps that: (a) the IP camera acquires a network state between the IP camera and the control platform; and (b) if the network state cannot meet the requirements of storage of the video shot by the IP camera, a dropped automatic video recording strategy is started. The invention also provides the video monitoring system. Video recording and unloading strategies different from those in the prior art are provided, so that error data or lost data during a network interrupt is automatically recovered on the premise of no influence on real-time video transmission quality, storage reliability and flexibility are effectively improved, and the problem of video data loss possibly caused by factors such as a network failure and jitter is effectively solved.

Description

Technical field [0001] The present invention relates to an information release control system, in particular an advertisement information release system, and in particular to a control method for releasing information according to the type of user terminal in the information release control system and a corresponding control device. Background technique [0002] Network cameras are mainly used in professional security systems. Real-time images of the scene can be monitored remotely via the network, and video information can be transmitted in digital form via wired or wireless IP networks. For network video surveillance, storage performance is almost as important as image quality, but the instability of the network directly leads to many storage problems: for example, network jitter leads to loss and incomplete recording; network jitter is the quality of transmission (QoS). A commonly used concept, which means the degree of change in packet delay. If the network is congested, the...

Problems solved by technology

For network video surveillance, storage performance is almost as important as image quality, but network instability directly leads to many storage problems: for example, network jitter leads to video loss and incompleteness; network jitter is a factor in the transmission quality (QoS) A commonly used concept, which means the degree of variation in packet delay

Another example is that the network is damaged by human beings, etc., resulting in image loss; whether it is wired or wireless transmission, any link failure will lead to problems in data transmission

For example, in wired transmission, poor contact of the end-to-end connection data line, damage to the data line during data transmission, and sudden power failure will cause the data to not be completely transmitted.

Or, in the use of wireless routing transmission, the quality of the wireless router has problems, the attenuation of the wireless network cable signal, resulting in an increase in transmission delay and packet loss rate, which will also cause a decline in communication quality
