There is a method to enter all your cameras in Security Monitor Pro and view 32 of them at a time. Enter the first set of 32 cameras, and save the camera profiles as a backup. Enter the second set of cameras and create a new backup. Do the same for the 3rd set of cameras. When you want to view the first set, simply restore the backup and you can preview or record from that set. Security Monitor Pro supports a maximum of 32 cameras at a time.
