Setting up and/or changing camera names is fairly simple, and helps organize and label your cameras for easier identification.
This type of naming is called the OSD (On-Screen Display). You can access these setting by right clicking on the main screen, then clicking Camera. Select the OSD tab from the menu.
Proceed to select the camera you want to name from the drop-down box, then add the name (you can choose to display the date, time, and other info as well). You can then change the font size and color to your preference. The final step is to drag the name on the screen to where you would like it to display on the camera view. Finialize your changes by clicking the Apply and Save buttons.
