This section explains how to control the access permission by checking the client PC’s IP 
addresses. It is composed of the following four columns: Allowed list, Denied list, Delete allowed 
list, and Delete denied list.

There are two lists for permission control: Allowed list and Denied list. Only those clients whose IP 
addresses are in the Allowed list and not in the Denied list can access the Network Camera.
1. In the Allowed list or Denied list column, type the starting IP address and ending IP address in the text 
    boxes. A total of ten lists can be configured for both columns.
2. Click Add to take effect.

► For example, when the range of allowed list is set from 1.1.1.0 to 192.255.255.255 and the range 

    of denied list is set from 1.1.1.0 to 170.255.255.255, Only users’ IP located between 171.0.0.0 and 
   192.255.255.255 can access the Network Camera.

1. In the Delete allowed list or Delete denied list, select a list from the drop-down list.
2. Click Delete to take effect.
