Order notifies this headend equipment the identification information of the NVR with vacant ability, so that this headend equipment has vacant energy to this
The NVR of power initiates registration.
The NVR equipment that headend equipment priority of registration is connected to it, once NVR equipment pressure exceed certain threshold value or
The NVR equipment extension that is out of order is dead, and headend equipment can switch and is registered to video management server, or video management server according to
Current pressure itself situation also can be further switched on other NVR equipment by instruction instruction headend equipment.Such as front end
Device IP C1 perceives the NVR equipment NVR1 fault or offline that it is registered, then IPC1 is to the registration pipe of video management server
Reason module initiates registration, asks to be registered to this video management server.The now registration management mould of video management server
Block checks the energy of other NVR equipment such as NVR2 and NVR3 management headend equipment in the NVR equipment that video management server manages
Power, if all no vacant ability of NVR2 and NVR3, video management server itself is taken over this headend equipment IPC1, is accepted IPC1
Registration；If it find that the ability that other NVR have a management headend equipment also has vacant ability, such as NVR2 is free complementary energy power,
Then by message signaling by the title of NVR2 and IP address information notify IPC1, IPC1 learn after the IP address of NVR2 just to
This IP address initiates registration request, and NVR2 accepts the registration of IPC1, thus IPC1 is registered to NVR2.
In above-described embodiment NVR device fails or offline when can not certainly use described registration request side
Formula carries out redundancy protecting.For example, can within the cycle setting, periodic scanning or triggering be more by the video management server on backstage
Newly arrive and find the fault of the corresponding NVR registering of IPC, video management server supervises regarding of NVR1, NVR2 and the NVR3 connecting
Frequency evidence, knows the capability state of each NVR equipment, when NVR1 equipment fault NVR3 is idle, can pass through video management
