I need to find a good replacement for a Samsung SCC-B5399HN. Mine is dead- filled with water. It is mounted to the ceiling of my entryway- outside but covered. I have an analog DVR system installed 8 years ago and the BNC connector and a green pin power cord is hanging in the breeze- anybody have any suggestions- also I am not familiar with this power connector- my indoor camera have a regular power plug. Please help. Thank you
