•
Port 25 (inbound and outbound):
Used for SMTP traffic. SMTP (Simple Mail Transfer Protocol) is a standard
for sending e-mail messages between servers. This port should be open since, depending on configuration,
some cameras may send images to the surveillance system server via e-mail.
•
Port 80 (inbound and outbound):
Used for HTTP traffic between the surveillance server and cameras,
NetGuard and/or NetGuard-EVS, and the default communication port for the surveillance system's Image
Server. HTTP (HyperText Transfer Protocol) is a standard for exchanging files across networks; widely used
for formatting and transmission of data on the world wide web.
•
Port 1024 and above (outbound only):
Used for HTTP traffic between cameras and the surveillance server.
•
Any other port numbers you may have selected to use, for example if you have changed the
Image Server
's
port from its default port number (80) to another port number.
Tip:
Consult the administrator of your organization's firewall if in doubt about how to open ports for traffic.
Windows Vista Information
If you wish to install, configure and run NetDVMS on a Windows Vista computer, it is important that you have
administrator rights. If you only have standard user rights, you will not be able to configure the surveillance system.
The restrictions are applied by the so-called User Account Control, a security component in Windows Vista. Note,
however, that it is possible to disable User Account Control. For more information, search

User Account Control
or similar.
Time Server Recommended
All images are time-stamped by NetDVMS upon reception, but since cameras are separate units which may have
separate timing devices, power supplies, etc., camera time and NetDVMS system time may not correspond fully, and
this may occasionally lead to confusion.
If supported by your cameras, we recommend you auto-synchronize camera and system time through a time server
for consistent synchronization.
