Embodiment Construction
[0009] This method realizes the plug-and-play method of network surveillance video. The network video recorder NVR adopts a plug-and-play module with multiple network ports. The main control chip of this module is connected to multiple network ports through the Switch chip. There is one-to-one correspondence between the video channels of the camera IPC; when an IPC is inserted into the network port, the NVR gets the MAC (Medium Access Control) address of the IPC, through the RARP (Reverse Address Resolution Protocol, reverse address translation protocol) protocol Assign a new IP address to the IPC, and the NVR automatically logs in to the IPC after the address is assigned; when an IPC is pulled out from the network port, the NVR detects that the IPC is removed, and removes its MAC address from the network port configuration table.
[0010] figure 1 A schematic diagram of the connection between the NVR and the IPC according to the present invention is shown. The Switch chip is...
