Trouble Condition: "Camera Busy"
The LifeShield Indoor Security Camera responds best if given one command at a time.
If Camera is busy and not responding to commands, you may have given it too many commands at one time. Wait 5 minutes for Camera to process all of the commands. Check Camera status on your LifeView account to ensure the Camera is ready. Your Camera will also not respond if you are accessing the same Camera from multiple sources (mobile app, tablet). 
In order to avoid this problem, give Camera only one command at a time, and wait for each one to finish (camera will indicate ready) before giving next command.
