5 Web Operation
5.1 General Introduction
The device web provides channel monitor menu tree, search, alarm setup, system setup, PTZ control and
monitor window and etc.
Important
The following operation is based on 32-channel series device.
5.1.1 Preparation
Before log in, please make sure:
 Network connection is right
 NVR and PC network setup is right. Please refer to network setup(main
 menu->setting->network)
 Use order ping ***.***.***.***(* NVR IP address) to check connection is OK or not. Usually the return
TTL value should be less than 255.
 Open the IE and then input NVR IP address.
 System can automatically download latest web control and the new version can overwrite the
previous one.
About PoE address setup, operation and allocation.
1) Insert PoE
After you insert PoE, device may try to set a corresponding IP address of the Switch network adapter.
First, system tries to set via arp ping. It then uses DHCP if it finds the DHCP is enabled. After successfully
set IP address, system may use Switch to send out broadcast, system considers the connection is OK
when there is any response. Now system is trying to login the newly found IPC. Now please check the
interface, you can see the corresponding digital channel is active now. You can see a small PoE icon at
the top left corner. You can see the PoE channel, PoE port information and etc from the connection list of
the registration interface (Chapter 5.8.1.1). For the IP search list, you need to click the IP search to
display or refresh.
2) Remove PoE
After you removed PoE, you can see the corresponding digital channel becomes idle (disable). On the
registration interface, it is removed from the connected list. For the IP search list, you need to click the IP
search to refresh.
3) After you insert PoE, system follows the principles listed below to map channel.
a) If it is your first time to insert PoE, system can map it to the first idle channel. After map, the
channel can memorize the MAC address of the IPC. It is a <Channel>---<IPC mac> map. If
current channel does not connect to other device, system can memorize current MAC
address, otherwise it can refresh to the newly added device and memorize the <PoE
port>---<Channel>.
b) If it is your second time to insert the PoE, system can check the saved MAC address
according to <Channel>---<IPC mac> map to make sure current IPC has connected or not.
If system finds the previous information and the channel is idle, system can map it to the
previously used channel. Otherwise system goes to the next step.
