Film i watched last year, i would say no more than 10 years old. Family, mum, dad and daughter move into new house. They find a video camera (i think) and see a boy who used to live there who had filmed himself on the camera, i think he gets killed or witnesses a murder as he films himself, later she finds she can talk to him through the camera in the past therefore getting him to safety so he doesnt die. She wakes up to find her whole life has changed due to this, she is married to a new man, doesn't have her daughter anymore and tries to contact him again, has to go back to the house with the videp camera that isnt her house any more. I would love to watch this again but google isnt helping me find the title. Any clues?
