5.11.18 P2P

P2P is a kind of convenient private network penetration technology. Instead of applying for dynamic
domain name, mapping ports or deploying transit server, you can add NVR devices to the app for
remote management.
This function will consume the device traffic when the device is online.
Procedure
Step 1 Select Main Menu > NETWORK > P2P.
Table 5-72 PoE operation
Description
When an IPC is connected to the PoE port, the system automatically
assigns the IP address to the IPC according to the set IP segment. The
NVR will try the method of arp ping to assign the IP address. If DHCP is
enabled on the NVR, the NVR will use DHCP to assign the IP address.
● When IP address is successfully set, the system will broadcast
through the switch function. If there is a response from the IPC, it
means the connection is successful, and the NVR will log in to the
IPC. You can find the corresponding channel occupied and there is a
PoE icon at the upper-left corner.
● You can also view PoE status such as channel number and PoE port
number on the Added Device list in Main Menu > CAMERA >
Camera List.
When an IPC is disconnected form PoE port, you will find the
information of Failed to find network host on the live channel window.
The PoE ports are bound to corresponding channels. When an IPC is
connected to PoE port 1, the corresponding channel is Channel 1.
