I am needing a indoor wireless IP Camera that would watch an unattended home and record the video for a maximum of 3 days. Something that would have low light capability would be helpful but not required. I would like to record to a NAS box, but would set up a spare computer if I had to. The ability to view the video over the internet is not needed. Just the ability to record any trouble at the home while I am away. My budget for the camera is $250 or hopefully less. Thanks for any help.
