* Masking on 32
nd
bit has the same effect as masking none, and in Webthru 0 instead of 32 is used.
Masking 32 bits means that all the 32 bits are network ID, and masking none means that all the 32 bits
are host ID. Therefore masking all the 32 bits or none means that the provided IP address itself is applied
with a command of ‘Allow’ or ‘Deny’.
If you want to allow only the IP addresses from 192.168.1.61 to 192.168.70, you may set as bellows.

* The IP addresses in black squares can be any IP address of the sub-networks. In the first square,
192.168.1.60 to 192.168.1.63 is to be assigned. And in the second square 192.168.1.64 to 192.168.1.71 is to
be assigned.
(2) Image Encryption Mode
Administrator may restrict people to receive images from one’s Webthru, even though people accessed it. If
‘Image Encryption Mode’ is enabled and a pin number is assigned, people have to key in the assigned pin
number to see image after accessing Webthru image viewers.
‘Security Configuration’ is a double-checking function to control accessibility, utilizing ‘User Account
Configuration’ at the same time.
7) Video Configuration
This page is to configure every channel with
various conditions.
(1) Video Channel Selection
To select which video channel to configure.
In the list, there are 6 video channels.
(2) Video Channel State Control
It is to determine which channels will be enabled to send image signals to the image viewer. If a channel with
an external source is disabled, no image will appear in the image viewer. However, if a channel without an
external source is enabled, the overall transmission speed will go down and no image will appear. To view an
image from an external source, the channel with the source must be enabled.
