I have a DS-2DF8836IX-AELW PTZ camera that seems to reset every night, my big issue is that it does not return to the home position. I come in every morning now and need to check on the camera that is overlooking a parking lot, and most mornings it is pointing straight at the ground. Now if I click the home button, it will return to the set position that it is configured for. I am not sure why it will not return to it's initial position on it's own? Sugguestions?
