A dual-mode video acquisition and transmission method and transmission system

Abstract

The invention belongs to the technical field of communication, and discloses a dual-mode video acquisition and transmission method and a transmission system. The dual-mode video acquisition and transmission method includes: a video camera is connected to a dual-mode video acquisition and transmission device through a wired network cable or a wireless local area network; according to configuration parameters, Select different acquisition and transmission modes; use different video acquisition and transmission methods for different acquisition and transmission modes to perform video acquisition and transmission respectively. The present invention utilizes 3G / wireless local area network / wired Ethernet multi-mode data transmission, and can be set to re-encoding mode and is compatible with multiple brands of cameras to simplify the software of the monitoring center, flexibly respond to monitoring requirements in different situations, and ensure video surveillance within the monitoring range. The normal transmission can be used for building security / people flow monitoring.

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a dual-mode video acquisition and transmission method and a transmission system. Background technique [0002] The existing technology of video surveillance network achieves real-time monitoring through wired transmission. At present, video surveillance can easily achieve full coverage of the entire building through a wired LAN. This kind of individual location is often very convenient to bridge through a short-distance wireless LAN, but it does not match the wired camera of the existing solution, and this monitoring method will generate huge waste during the secondary construction process - once the secondary construction is replaced For camera manufacturers, if the products of two manufacturers are merged into one monitoring system, it is often difficult to be compatible with the software and hardware.

[0002] The existing technology of video surveillance network achieves real-time monitoring through wired transmission. At present, video surveillance can easily achieve full coverage of the entire building through a wired LAN. This kind of individual location is often very convenient to bridge through a short-distance wireless LAN, but it does not match the wired camera of the existing solution, and this monitoring method will generate huge waste during the secondary construction process - once the secondary construction is replaced For camera manufacturers, if the products of two manufacturers are merged into one monitoring system, it is often difficult to be compatible with the software and hardware. Therefore, a multi-network method is required, which is compatible with the acquisition units of the software and hardware of multiple types of camera manufacturers, and connects a small-scale video surveillance network. The entire monitoring network ensures the effect of monitoring and controls the compatible cost of multi-vendor products within a reasonable range

[0003] To sum up, the problems existing in the existing technology are: it is very difficult to add or update cameras in the traditional video surveillance system through wired installation, it is difficult to expand the monitoring network, and the products of multiple manufacturers’ camera manufacturers are in a monitoring system. The compatibility is not good, and the transmission Once there is a network problem in the network cable layout, the monitoring stops, resulting in blank time, and the layout cannot be changed after one-time construction, cannot be reused, and the expansion investment is large

[0004] Difficulty in solving the above technical problems: the layout cannot be changed after the current limited video surveillance network is deployed, especially adding a new camera is very difficult; if the newly added camera is a camera from a different manufacturer, it is even more difficult; and in the process of using the system If it is necessary to replace a new camera with higher resolution and faster speed, it will be more difficult

However, in practical applications, we often encounter the need to expand the monitoring area and add surveillance cameras to the original monitoring area, as well as the problem of updating new models of high-definition cameras.

Whether it is to increase the monitoring area or increase the camera, the transmission network that adopts wired layout needs to increase a lot of wiring, and it is difficult to troubleshoot the fault point and cause of the fault when the network fails.
