Web Service
The Web service contains the same functions as are available in local operation.
Note:
There might be a slight difference in the screen depending on the model. The following
examples are for the 8-channel product.
4.1
Network Connection
Before Web operation, check the following items:
1.
Verify that you have a valid network connection.
2.
Verify that the NVR and PC network setup is correct. Refer to network setup (
Setup > Network
).
3.
Ping the NVR IP address (***.***.***.***) to verify that the connection is good. The return TTL value
is usually less than 255.
4.
Open a browser window and input the NVR IP address. The system automatically downloads the
latest Web control and overwrites the previous one if necessary.
5.
To uninstall the Web control, run
uninstall Webrec3.0.bat
. Alternatively, you can go to
C:\Program Files\Webrec
to remove a single folder. Before you un-install, be sure close all Web
pages to avoid errors.
Note:
The NVR supports most Web browsers, such as Internet Explorer, Safari, Firefox and
Chrome. The device only supports 1-channel monitor on the Apple PC.

About PoE Address Setup, Operation and Allocation
1.
Insert PoE
After you insert the PoE, the device may try to set a corresponding IP address of the Switch network
adapter. First, the system tries to set via ARP ping, and then uses DHC if it finds the DHCP is enabled.
After successfully setting the IP address, the system may use Switch to send out a broadcast. The
system thinks the connection is OK when there is any response. Next the system tries to login the
newly found IPC. Check the interface to see whether the corresponding digital channel is active now.
A small PoE icon appears at the top left corner with the PoE channel and PoE port information from
the connection list of the remote device interface (section 3.2.1). For the IP search list, you must click
the IP search to display or refresh.
2.
Remove PoE
After you have removed the PoE, the corresponding digital channel becomes idle (disabled). On the
remote device interface, it is removed from the connected list. For the IP search list, you must click
the IP search to refresh.
3.
After you insert PoE, the system follows the following principles to map the channel
a)
If it is your first time to insert the PoE, the system maps it to the first idle channel. After the
mapping, the channel memorizes the MAC address of the IPC ( <Channel>---<IPC mac> map).
If the current channel does not connect to other device, the system can memorize the current
