Hello,

Trying to find the name of movie with same story line similar to the movie "Saw" a bunch of teenagers woke up in a empty warehouse and they each had to complete a dangerous task in order to survive and one of the victims was the killers daughter. Saw it on cable

I believe the movie you speak of is "are you scared" It came out in 06. He watches them all with camera's he has set up throughout the warehouse in his own little secret room.
