  1. If the IP address, name and password entered in the camera configuration page are correct, You could use the Test function to verify the connection.
  2. When the PC and the network camera are in the same subnet, while VioStor is in another one, you cannot view the monitoring screen from the PC. You can solve the problems by the following methods
    • Method 1: Enter the IP address of the network camera as the WAN IP in VioStor.
    • Method 2: Configure the router to allow internal access to the public IP address and the mapped ports of the network cameras.

You could refer to the NVR Installation Guide.
