In EasyView you can set up a favorite group so that when you select it, the channels that have been marked in this way will be opened directly
For the program to work properly, at least 4 Gb of ram and 4 cores are required.
In Configuration, go to the settings icon in the upper right corner, activate the 4 options that are disabled.
To display this mode, it is necessary to add each of the cameras to favorites. This is done by checking the favorites icon (yellow star) that appears at the bottom next to the camera thumbnail.
This can be done both for the IP cameras added to the software and for the required channels of the recorders
Once all the cameras have been added, then click on Favorites and it will open in quad mode, in 4, 9, 16 or 25.
You can change the type of grid by selecting one of the 4 modes in the bottom bar. View a single camera by double-clicking on it and return to quadrant mode by double-clicking on it or by clicking on the thumbnails below.
