In order to get both channels from a Dahua IPC-HDBW4231F-E2-M camera into VI MonitorPlus, select ONVIF as the manufacturer and ONVIF Profile S Compliant Camera as the model. Select the Shared IP Address checkbox and use Camera # 1 for channel 1 and Camera # 3 for channel 2 (camera numbers 2 and 4 are for the secondary streams). Each channel needs to be added as a seperate camera.
