I always thought copper was copper was copper, but I have been wrong before...

Running any cable outdoors requires protection against impacts like lightning, UV, rodents, other EMI sources, and weather. Coax by nature has a shield, but STP cable for outdoor cameras is a routine requirement. See: STP vs UTP for Surveillance
On other words, there is no reason IP cameras cannot be run outside.
I have seen water get into a cable through a pin prick in the jacket and fill the cable. Then the water made it's way to the POE port and shorted it out.
FWIW, this can still be due to lightning. A lightning strike that doesn't take out the cable, (due to proper bonding/grounding), can still cause conductive pinholes at the site of where the surge enters. These can let moisture in and eventually cause failure. IMHO, gel-filled cables would deter this.
Certainly UTP would be more susceptible to lightning damage than coax. It's basically 8 unprotected and ungrounded conductors so...
On the other hand, as Brian points out, STP is usually run outdoors for this reason, among others. Assuming that the shielding is carried thru all insertion points and grounded properly, I don't see why it would be more susceptible than coax.
If you and the IT Director are arguing about existing outdoor cable and its UTP; then you may want to let it drop. If the cable is STP or you are talking about future cable, you should stand your ground.
The existing cabling is STP. I will be running new cable anyway for a couple of reasons. 1.) their uneducated choice of camera locations does not cover what the board wants 2.) with so many claims of lightning being the issue, I want to start with a fresh install.
With every solution I bring up for surge protection, the IT Dir continues to play devil's advocate. He says "Done that, didn't work, good luck with that." I really get the feeling this is personal. I could imagine being in his shoes... spent the money and tried twice but failed and now a non-college degree security integrator thinks he can make it happen. I just know that I have installed hundreds of cameras outdoors in the same area and not one lightning strike causing mass failure. Not to mention two strikes. Wondering if maybe the facility has other electrical issues that cause it to be more affected by nearby strikes? Or maybe the circuit the original switch was on took a hit that caused damage and he used the same circuit the second time without checking it?
My proposal will definitely include any and all surge protection devices and techniques I can come up with. It seems that the only selling point I need to push is surge protection and not camera system bells and whistles.
What are your "go to" products for surge suppression/protection? I'm not here to solicit my products (unless you'd like my $0.02); I would just like to know what people are using and their experiences... Disclosure: I rep some surge suppression products.
