auto pics after motion is detected on i-phone 4

Need to program my i-phone 4 to sit on its own and detect motion. Then the motion detection should trigger pics that are automatically uploaded to email.

So basically if I can set the phone up this way ...

The phone will be propped up facing the direction of the expected activity. Photos will automatically be taken by the phone and uploaded to my email. Actually uploading them to i-cloud will also work as long as it is automatically triggered. Pretty sure all readers understand that I do not want any photo taking or email uploading to happen whwhile

While the phone is sitting on its own, I prefer that it be locked. I would also want to choose an interval between photos and an expiration time limit on the motion. Then the task should automatically reset.
