Problems solved by technology
If load consumption, signal conflict, distance, signal strength, interference and other factors are considered, the final bandwidth may be even smaller
At the same time, after the wireless connection between the IPC and the AP is interrupted, the user cannot remotely access the IPC for viewing and maintenance, and can only perform maintenance through wired login at the equipment site, and the maintenance workload is heavy.

Embodiment Construction
[0019] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.
[0020] figure 2 It shows a schematic diagram of the structure of the wireless video surveillance network of the present invention, in which each wireless network camera (IPC1, IPC2, IPC3) is connected through a network cable and stacked into a stacked camera group, wherein one wireless network camera is the main IPC, and in addition Two are slave IPCs. For example, IPC1 is the master, then IPC2 and IPC3 are slaves. The multiple wireless transceiver modules of the stacked camera group together form a MIMO transceiver system. Each IPC is a plurality of independent IPCs at the service level, and is equivalent to an 802.11n device at the forwarding level. When an IPC needs to send a data stream, it only needs to send the data stream ...

The invention discloses a stackable wireless network camera. The stackable wireless network camera comprises a stacking module which is used for being in series connection with adjacent stackable wireless network cameras, and the adjacent stackable wireless network cameras which are in series connection are stacked into a stacking camera set. The stacking module comprises a connecting unit, a neighbor discovery unit and a control unit. According to the stacking camera set, a plurality of independent 802.11n wireless network cameras are stacked to be an MIMO supporting stacking camera set, wireless access bandwidth is effectively improved, meanwhile, the wireless network cameras form backups, and after wireless access of one camera is broken, the camera still can have access to other cameras in the stacking camera set in a wireless mode for communication.
Description
technical field [0001] The invention belongs to the technical field of wireless network cameras, in particular to a stackable wireless network camera. Background technique [0002] Video surveillance is an important part of the security system. 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, the popularization trend of video surveillance has become more and more obvious. Video surveillance plays an increasingly important role in urban security. As a result, more and more monitoring points are deployed. Currently, the cameras deployed at monitoring points include analog cameras and network cameras (IPC). However, most cameras require wired connections, but it is inconvenient to directly connect wired connections in many locations where cameras need to be deployed, so wireless network ...
