I plan to install my own IP security cameras around my home for the first time. One of them will on the back of my home to monitor my back yard. My question has to do with my research and some threads that refer to some cameras that have heaters and fans. I live in the Southeast and my backyard is in the sun most of the day. Temperatures during the summer get well above 100 degrees F on a regular basis. While I could install a dome like camera under one of my eves, this position would be too low to cover my entire yard. Installing a bullet like camera higher up would give me the coverage I would need but would expose the camera to sun. Do I need to purchase an 'industrial strength" camera with a fan or would a 'well made' IP camera suffice for this type of environment. Thanks for any assistance offered.
