If you are using My Screen Recorder Pro's scheduling system to create your recordings, you can use a simple command line to remove files older than x number of days from your PC before beginning the recording. Here is an example command line to delete recorded WMV files over 30 days old from the E:\Recordings folder: forfiles /p E:\Recordings /s /m *.wmv /d -30 /c "cmd /c del @file" Change the E:\Recordings to the correct folder name where your recordings are stored.

Security Monitor Pro will not conflict with the Foscam software. Both can be run at the same time. I do recommend that you use the 4 cameras in a wired mode rather than wireless as it will be more a reliable network connection and give a faster and smoother preview.
