NTP
Network Time Protocol (NTP) is used to synchronize the time of a computer or other device
connected to the Internet. Utilizing this feature allows your DVR to keep an accurate time as
well as automatically adjust to Daylight Savings Time changes.
NTP was set up as part of the Startup Wizard process, but you can always return via the
Advanced Settings area of the Network menu to make adjustments.

Server IP - The default server used to
obtain accurate time is the Windows
server, but you can manually enter in
another.
Port - This is the port that the DVR
will use to contact the server.
Time Zone - You will need to set your
time zone. For North America these
are:
Eastern Time Zone = GMT-5 Central Time Zone = GMT-6
Mountain Time Zone = GMT-7 Pacific Time Zone = GMT-8
Alaskan Time Zone = GMT-9 Hawaii Time Zone = GMT-10
Update Period - This is the frequency at which the DVR will check the time with the
server.
Synchronize - Clicking this will cause the DVR to update the time immediately.

IP FILTER
You can also improve security by controlling remote access to your DVR using the IP Filter.
This feature enables you to allow online users only from approved IP addresses. Up to 64
addresses may be entered.
Enter the trusted IP addresses into the field at
the top of the window and select Add IP to
add that address to the list of those allowed
to connect to the DVR.
Once this feature is enabled, only IP
addresses within this list can be used to
access the DVR. If this feature is not enabled,
then users can connect from any IP address
if they have the correct user name and
password information.
