4.2.1 Connecting to Internet
Two common connection methods are shown below
1. Connecting via switch or router
4.2.2 Using Marshall VMS Software to View the Images
• The CV420-30X DHCP initial setting is ON. If it is connected to the local area network (LAN), the
camera IP can be retrieved via the following methods
• Install Marshall VMS software (Please download from the Marshall official website, www.
marshall-usa.com)
• Open Marshall VMS software
• Search for the camera: Press [automatically search for the device] button to locate the
CV420-30X camera
• Click CV420-30X in the list and start operation after connecting to network
Note: When using automatic search, the camera and computer must be in the same network
segment, e.g.: 192.168.4.X
2. If the camera is connected to the computer directly, the computer IP address must be
modified to have the same network segment as the camera
For example, the factory-preset default IP address of CV420-30X is 192.168.100.100. The
computer IP address must be set with the same subnet, such as 192.168.100.101, so that the
computer can be connected correctly with the camera
