Other mistake: We are seeing the movie as if we were watching recordings, that's why we see the surveillance camera shots as the device installed to change from one camera to another would let us. It takes very short time from one camera to another,but in some cases, as to follow things to happen, the shot stays in one angle (camera) for a longer period, not keeping the timing for the mentioned device.

Paranormal Activity 2 (2010)
1 other mistake
Directed by: Tod Williams
Starring: Katie Featherston, Molly Ephraim, Micah Sloat, Brian Boland, David Bierend
Revealing mistake: At the end when Katie enters Hunter's room and throws Kristi against the camera, Katie's reflection in the wardrobe mirror shows her in a different position from when she attacks Kristi, to after she drops out of view.
Daniel Rey: We just can't let this affect us that much. If we do that, the terrorists win.
Trivia: Originally, Kevin Greutert, who edited the first five "Saw" movies and also directed "Saw VI" and "Saw 3D," was attached to direct. However, Lionsgate enacted a contractual clause to remove him from the film. While an exact reason was never given, it has been widely speculated that this was done because the "Paranormal Activity" movies were the only direct competition for the "Saw" series at the box office.
