The camera had not been turned on? Interesting, how do they know when it was on or off last? Based on the recording of the in-house recorder? What if there was an out of the house recorder? I am not very techy, but my son has a camera in his son's room, so when the baby is sleeping he can check on him from a little hand held monitor. To me the scene in the pool area, could have been recorded and viewed by somebody off site. I think that would have been pretty simple in this day and age.
