Ninja Security Camera (Free until contract is in place!) $2.99
Turn your auto-lock to never, set your brightness low and try to power your device. Once launched the app will be armed in 10 seconds. The app will then begin recording movies if it encounters any audio and/or video triggers. You can also choose exactly what dB level to trigger the recording and swap between front/back facing cameras.
Once the camera has been triggered, the app records a movie for no less than 30 seconds into your iPhone library, of course if there is still activity the camera keeps recording ;).
The real time image processing algorithm is sensitive enough to capture the gradual light changes of a room. When deployed in an environment where high speed image differencing is required to catch a glimpse of the target, you can't beat our realtime image differencing algorithm.
•Realtime image differencing algorithm
*Swap Front/Back facing cameras (iPhone4)
•Fully adjustable sound triggered recordings

Leave this camera running as a security device to see what is lurking in your room after you leave, NO NINJA should be without this quickly deployable and solid tool.
