Great thoughts, thanks so much!
They are both set up wireless, different brand routers. You are sure right about the modem affecting behavior... I had to completely replace my Florida modem as the camera connection would die every 12 hours. New modem, no more problems there!
My firmware in Florida is 1.01 0902, Georgia is 1.02 1030. Makes me hesitate to upgrade Florida, lest I bring on the Georgia problem.
Unfortunately I don't yet have an SD card in Florida, so I'm unable to test for the problem of changing the motion detection area. I'll fix that at Christmas and see if the problem is the same.
Finally, either I didn't understand your comment or (more likely) I didn't explain my question very well. I'm asking if you know if one must be on the same network as the camera to change the motion detect area. I might be trying to do the impossible. That would eliminate one of my two problems pretty quickly!
Thanks again!!
