Abstract

The invention discloses a channel number expansion method of a net-harddisk video recorder. The method comprises the following steps: obtaining the to-be-accessed number of to-be-accessed devices thatrequest to access the net-harddisk video recorder; when the to-be-accessed number is greater than the remaining channel number of the net-harddisk video recorder, expanding the original channel number of the net-harddisk video recorder to a preset channel number; and after the original channel number is expanded to the preset channel number, accessing the to-be-accessed devices to the net-harddisk video recorder, and adjusting the code stream parameters of the accessed devices in the net-harddisk video recorder according to the preset channel number. By adoption of the channel number expansion method disclosed by the invention, the original channel number of the net-harddisk video recorder is expanded without increasing additional hardware so as to increase the accessible number of the accessed devices in the net-harddisk video recorder, the monitoring demands of different users can be met on the basis of ensuring the stability and the smoothness of the monitoring, and the investmentcost of the monitoring is reduced. The invention further provides a net-harddisk video recorder, a channel number expansion device and a storage medium.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method for expanding the number of channels of a network hard disk video recorder, a device, a network hard disk video recorder and a storage medium. Background technique [0002] In the monitoring system, the network camera is generally connected to the network hard disk video recorder through the network, so as to convert the collected video image into a compressed video code stream and send it to the network hard disk video recorder, and the network hard disk video recorder receives the video code stream transmitted by the network camera, and It can be stored, previewed, played back and forwarded, so as to monitor the designated area. [0003] Existing network hard disk video recorders generally include multiple channels, which allow the connection of a corresponding number of network cameras, but the number of channels in existing network hard disk video recorders is gen...
