NVR 2.2 SP3 (V2.2.57) User’s Manual

Ports and Firewalls
Several ports are needed to transmit data for NVR. Please properly configure the firewalls
on the Server PC, Workstation PC and the routers in between. Blockage in any point of the
way will prevent NVR from functioning properly.
In Some cases, you may need to allow unlimited access through firewall for NVR core
services. This is required if you use RTP protocol for communication. You can go to Control
Panel -> Windows Firewall -> Allowed Programs to add the following two programs to the
allowed list:
C:\Program Files\NVR\ActiveStreamEngine\ActiveStreamingService.exe
C:\Program Files\NVR\ActiveScheduleService\ActiveScheduleService.exe
Sample screenshots from Windows 7 are shown below. The steps are similar in other
