Embodiment

As shown in Figure 2, be the Organization Chart of network camera management devices of the present invention preferred embodiment.This Organization Chart comprises access node, and (access point, AP) equipment 1, reaches the network camera 2 and the monitoring client 3 that link to each other with this AP equipment 1 by network.This AP equipment 1 comprises a central processing unit (CPU) 10, at least one interface (LAN port) (12a as shown in FIG., 12b, 12c, 12d), and the memory device (not shown) that links to each other with this CPU10, there is a wiring list 14 in this memory device.

Wherein, CPU10 follows DynamicHost and sets agreement (dynamic hostconfiguration protocol DHCP), but gives network camera 2 by the automatic distribution function distributing IP address of this DHCP.

Known, every network camera its hardware net when the production shipment can be set an independence and unique Media Access Control address (media access control address, MAC Address), while also can set an independence for this network camera 2 of management and control and unique numbering is given this network camera 2, so that the tracking and managing of maintenance or subsequent product.When setting up network camera 2, the staff can learn this network camera 2 MAC Address, number and set up the place, as to be erected at the a-quadrant still be the B zone.Present embodiment according to this MAC Address, number and set up the corresponding relation between three data such as place, set up a wiring list 14, as shown in Figure 5, write down numbering, the Media Access Control address (MAC Address) of each network camera 2 in this wiring list 14 and set up the place, and respectively set up the IP section of place correspondence.This IP section that respectively sets up the place correspondence can be set up on their own by the user, also can be distributed automatically by the DHCP mode by CPU10.

In the present embodiment, this network camera 2 is a network extension video camera.As shown in Figure 3, this every network camera 2 interior camera lenses 20 except installing successively, sensor 21, encoder 22, processor 23, outside flash memory 25 and the memory 26, switch 24 with at least three network interfaces also is installed, network interface 240a as shown in Figure 3,240b and 240c, wherein, network interface 240a is Media Independent Interface/RMII (Medium Independent Interface/Reduce Medium IndependentInterface, the MII/RMII interface), switch 24 is connected in series with processor 23 by this MII/RMII interface, and this processor 23 can be CPU or MCU; Network interface 240b links to each other with AP equipment 1 by network, sends these network camera 2 captured images to monitoring client 3 by this AP equipment 1; Network interface 240c can be connected in series a network camera 2 in addition, the quantity of the network camera 2 that extended.By the structure of this network camera 2, each interface of described AP equipment 1 can connect many network cameras 2.

In order to improve managerial convenience of watch-dog and conformability, each interface of the AP equipment 1 in the present embodiment can connect the network camera 2 in different monitoring zone respectively.For example, interface 12a link is located at the network camera 2 in the a-quadrant, and interface 12b link is located at the network camera 2 in the B zone, and interface 12c link is located at the network camera 2 in the C zone, and interface 12d link is located at the network camera 2 in the region D.The IP address of network camera 2 utilizes the DHCP mode to distribute by CPU10.

For example, CPU10 distributes to the a-quadrant with IP section " 192.168.1.1～192.168.1.255 ", another IP section " 192.168.2.1～192.168.2.255 " is distributed to the B zone, the method of salary distribution can make the network camera 2 in the different monitoring zone can be assigned to different IP sections thus, and the information content by record in the wiring list 14, can make things convenient for the user to find out the IP address of each network camera 2 and set up the place, can't determine the situation of network camera 2 place guarded regions by the CPU10 Random assignment to avoid the IP address of network camera 2 in the past, and then reach each network camera 2 can be separated effectively the management, improved network camera 2 managerial convenience and conformabilities.

Connect to the Net when being connected with AP equipment 1 when network camera 2, the AP equipment 1 in the present embodiment will be carried out operational method flow process shown in Figure 4, and network camera 2 is carried out regional managements:

Step S400, AP equipment 1 receives the IP Address requests that network camera 2 sends.

Step S402, the CPU10 in this AP equipment 1 reads the MAC Address of described network camera 2.

Step S404, CPU10 searches wiring list 14 according to the MAC Address that is read, and to search the IP section of these network camera 2 correspondences, as shown in Figure 5, if the hypothesis place of described network camera 2 is the a-quadrant, corresponding IP section is " 192.168.1.xxx ".This mode can be carried out unified management with the network camera 2 that sets up in the same area.

Step S406, CPU10 gives described network camera 2 by automatic distribution function available IP address of Random assignment in described IP section of DHCP.

Step S408, CPU10 links up by network by this IP address and described network camera 2, with numbering and the MAC Address that reads described network camera 2, and with numbering, the MAC Address of this network camera 2 of record in this numbering that reads, MAC Address and the wiring list 14 with set up the place and compare.

Whether step S410 checks institute's IP address allocated according to the comparative result among the step S408 and sets correctly.

If checked result is that IP address allocated is when correct, then in step S412, CPU10 controls on the relevant position that described IP address allocated is saved in wiring list 14 automatically, record in wiring list 14 second row the 5th hurdle as the IP address " 192.168.1.2 " that will distribute among Fig. 5 the network camera 2 that is numbered " 2UAA4491A0 ", then process ends.

If checked result is that IP address allocated is incorrect, then return step S402, be that this network camera 2 is set the IP address again.

It should be noted that at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
