Sure thing, thanks for your input.

Not a lot of lightning strikes where I live and I don't know a whole lot about grounding stuff other than what I learned from researching how to ground my TV antenna.

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.

Ok, thank you for the reply, this confirms what I'm just been trying to figure out. I was actually thinking of getting two NVR of the system I'm looking at since they are cheap in price.

Hi, I don't understand why would one ip camera dealer say I need to purchase an NVR that is Xmeye.com compatible for the motion detection to work with their ip cameras. Another seller tells me their NVRs had to be nvsip.com compatible, meaning, they say, it needs to be one with a Jovision chip. I'm confused. Does this have anything to do with variations of ONVIF implementations from different manufacturers? The reason I'm asking, I don't want to set up my whole system, have the NVR break down and find out I can't get a replacement NVR for motion detection to work in my ip cameras because the company making the NVR no longer exist, if that's the case. I'm just being cautious because my crappy DVR stopped working properly after only six months of low usage (I'm changing from DVR to NVR for other reasons). Thank you for any response.
