Has anyone else had erratic control of their PTZ Dahua cameras using the iOS iDMSS app? I have someone with a SD49225T-HN, that says they often have issues where they go to move the camera using their iPhone, it just starts spinning around in circles. Their app is up to date, and I just installed the latest firmware from Andy on it. I have asked them to start using their computer more to make sure it isn't doing it on there as well. I haven't ever really had an issue on my Android phone controlling my SD49225XA-HNR, but I don't move it all that much with it. Wondering if anyone else has seen this issue, and found a way to correct it?
