Hi, I was wondering is it necessary to install a RJ45 surge protector such as the Tripp Lite DTEL2 2-Line for my outside cams? I live in a mobile home, not sure that makes a difference, but, I intend to run my CAT5e (direct burial type cable) under the floor, across to the skirts at the perimeter and under to outside straight up along the wall (no, I don’t like drilling holes in my eaves, so, this works best for me). I’ve heard some people say surge protection is a must when running wires outside, but, I’m not running wires to another building, only about seven feet straight vertical from the ground up almost to the eaves. Thank you for your input.
