I've been looking at getting the SD49225T-HN PTZ but it does not have auto-tracking, which I hear does not work all that well anyway. I was wondering if BI can be used to trigger PTZ presets based on motion tracking triggers. So, for example, My PTZ would sit zoomed full out as overview, ( I don't have one yet) so I set up in BI to detect motion near my mailbox, can I then tell it to turn and zoom in on the mailbox for a period then back to center position full overview preset again after X seconds or when motion stops? If so, could this be done with multiple different areas, like a trigger to zoom in on the garage in a completely different area if line cross is triggered over there? If so, say garage motion is triggered shortly after but during a mailbox trigger event...would it's logic be to stay on the mailbox or to stop and switch to the garage? Just trying to get a feel for what I could do with a nice PTZ and BI rules.
