To receive input pin events from your units in Security Center, the Archiver needs to open a TCP port for
its HTTP server. The default port is 8008; however, if this port is already in use on the
Archiver role machine, you must change the default port.
Procedure
On the Archiver role machine, navigate to the installation directory, for example,
C:\Program Files\Common Files\DVR Software
x.x\Extensions\Drivers\ on 32-bit machines, and C:\Program
Files (x86)\Common Files\DVR Software x.x\Extensions\Drivers\ on 64-bit
machines.
x.x refers to the Security Center version.
Open the EventHttpServerConfiguration.xml file in
Notepad.
