Do you have an advice how to do it right? as Telecommunication systems I would like to know too. Power at the remote location is not an option. Nice, Power at the remote location is not protecting the remote location, too; Still undecided PoE Ethernet Overhead vs Underground. If I go Overhead, messenger cable will help if grounded?

Do you have an advice how to do it right? as Telecommunication systems

• I have Fiber Optic internet service so that was not the source of the problem. • The ground system at the house was checked numerous times by the power/utility company & certified electricians. All of them said the ground at the meter base was excellent. • The meter base also has a whole house surge system installed by the utility company…It’s never indicated a surge. • The 275ft buried cat5/RG-45 cable was attached to POE Surge protectors within 1-2 feet of the cable leaving the earth (Camera side & POE switch side). The protectors were attached to 8’ ground rods. I used these POE surge protectors - APC PNET1GB http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=PNET1GB • The cameras were mounted to a wood (not metal) building. • The POE switch, cameras, and NVR are connected to a Pure Sine Wave UPS. This model – Cyber Power CP1500PFCLCD - http://www.cyberpowersystems.com/products/ups-systems/pfc-sinewave-series/CP1500PFCLCD.html I’ve NEVER had damage to any of my other equipment (NVR, router, cameras, PC, TV’s, VOIP device, etc). Just the POE ports connected to the 275ft buried cable. After replacing FIVE fried poe switches, I unhooked the cameras connected to the buried cable…I’ve not had any issues since & we’ve had some bad lightning storms. Hope this helps someone not make the same costly mistakes I’ve made. I would still love to know how to eliminate this issue in the future and what I did wrong?? So, I guess I get it right with the buried cables issue; Not to go buried because only buried links are made problems; Now my question is about the rest of your links that are ok without any issue: 1. Outdoor overheat(aerial) between two buildings/poles? what distance height!? 2. Outdoor overheat(aerial) along building's facade/eave? what distance height!? Details please of your outdoor IP Camera's ethernet links without issues! Awesome topic, one day probably will find the way to do it right

If these cams are on their own ground rod, that is probably part of the issue. You want everything tied to a common ground so all equipment is at the same voltage potential. Separate ground rods are going to be at different potentials during a surge event which is going to cause current to flow(unless they are tied together with some heavy copper) EDIT: just realized this is a pretty old thread....but still helpful for reference purposes Since my last post, I’ve removed the cameras that were connected to the 275ft buried Cat5. No matter what I tried, the POE switch was always damaged during thunder/lightning storms. However, the cameras were never damaged?? Here’s what I had – Each camera had surge protectors and 8’ ground rods installed at each end of the Cat5 cable where it left the earth (2 protectors & 2 ground rods per camera). I’m still open to all suggestions? What success stories do other people have with POE cameras & switches attached to buried Cat5? What is the best method to connect / stream IP cams from one building to another building, gate, etc.? why u still use 2 different ground rods per camera. More than that entire system(including power lines) as I understand should share the same ground.(single pont grounding). Now u still use at least 3 diferent grounds( 2 ground rods per camera and house's power line ground). My big question remain the same: Best way to run Copper Lan Lines, Overhead or Underground ???? Here is a link where I can understand that Underground in grounded metal conduit is the right way to go: http://www.kolumbus.fi/oh5iy/back/Ham%20Radio%20Lightning%20Protection.html

Hi everyone! I'm new on this forum but an old reader, great forum! I'm going to instal my IP cameras system, most of them will be outdoor. My big concern is about outdoor LAN network construction! Few questions: 1. Outdoor LAN lines underground or overhead is the best option for surge protectors to work right? I am confused which option will work best! 2. Outdoor grade, grounded SFTP/FTP in plastic conduit/duct or in an grounded metal conduit/duct? 3. Probably if in an grounded metal conduit/duct an outdoor grade UTP will work? 4. Also for multiple LAN lines in the same conduit/duct plastic or metal, SFTP/FTP is better do not interfere with each one? Any suggestion experience will be great!
