Yes.  You can change the resolution on Otter Camera HD.  The choices are 720p and 480p.  720p is full HD and requires a minimum 3Mbps of upload internet to work correctly.  The connection must stay above this threshold or camera dropout could happen.  480p is an SD resolution that can be used when bandwidth is under 3Mbps. 480p requires 2Mbps of upload internet to work correctly.
