Sorry for the delayed response. In regards to your question, With most cameras ,yes you do have to climb up to the camera every time you would like to access the cameras OSD menu. However some cameras use RS-485 cable to connect / interface with your DVR so that you can manage the OSD settings from your DVR.
Also you do not need to be a customer to get a response. However our responses on the support forum are sometimes delayed because direct customers are our 1st priority. I hope you can appreciate that.
