So I have installed indoor security cameras to check up on kitties while outside..

The camera shows playbacks once it detects kitty. Anyhow, two times I had pressed on the playback while thinking I pressed on live camera and when I went to the living room, I saw kitty somewhere else. I was getting rid of some boxes downstairs and was looking at the playback as I was entering my place at the same time.. it was showing kitty in the nook which is right beside the door. I seriously got so paranoid thinking who the heck is showing on camera when I can't see anyone live... then I realized it was playback.. i thought it was a kitty ghost.
