If you would like to schedule a period that starts before midnight, and ends the following day, you should create two Weekly entries. Let's say you want to start recording at 7:00 pm Monday and stop at 7:30 pm on Tuesday. Create an entry for Monday that starts at 19:00 and has no stop time, and one for Tuesday that starts at 00:01 and ends at 07:30. WebCam Monitor will monitor continuously between 19:00 and 07:30.
