Is there a way to protect POE cameras that are mounted on a post across the driveway looking back at the house? I have a project where the architect decided that the house would look better without eves.

Yes.  ITW Linx make several PoE surge protection devices for both Cat 5 and Cat 6.

They are the OEM that makes stuff for Panamax, so check pricing on both brands.

There are others too.  ITW Linx was the first company that popped into my head.

Do you have any experience with the ITW piece?

Ubiquiti has a decent kit as well. I've used them before with no issue.

Had an issue years ago with a Cat 5 unit.  Speeds got cut in half for some reason.  I've had no issues with the Cat 6 one.  I've not used any for several years as everything I do now between buildings is fiber.

I've not run into this, nor any power or image problems, that I might think were due to surges. What sorts of problems, other than a dead camera, would point toward a need for surge protection?

I'm not saying it doesn't happen. It would just be nice not to be shooting in the dark if some problem arises.

Issues are dead products. Not just the cameras. Wire running through the ground outside the house (even in conduit) is a lightning magnet. It will run back in the house and potentially destroy an entire system through the comm ports. I’m in the Appalachian mountains with a rural power grid where most of the lines are above ground. Add in the high mineral deposits in the ground, and the fact that the customer will want the cameras actually on or close to trees to help camouflage them.

It all makes sense now.

Well, electrical code in a lot of places for one thing.  Most low voltage contractors don't follow it however because it is rarely inspected.

The way I've always interpreted it, any low voltage cable that enters / leaves a building should be protected.

It is also best practice as recommended by BICSI and IEEE.

"Electrical Code" "in a lot of places" requires surge protection on all low voltage wiring where it exits/enters a building?

Fins,
I see the difficulty. I'm in the big city. So many of the hots and grounds are locked down by the lawyers ready to sue everyone that the situations you describe haven't even come up.

I've been amused to see a dish on a 10' 4x4 next to a front walkway gate. The idea of cameras in trees is pretty scary, so, yeah to surge protection!

As for lightning, is there really anything that can stop it if it hits near a CAT-5 or CAT-6?

Never seen a DTV dish mounted on a tree?

Long time ago, I did service for DTV (The old Hughes stuff back at the beginning).

Seems like at least once a month I would get a call for intermittent signal, and it was always the dish on a tree situation.


Remember those days when people shelled out $1,400.00 at the local store (Lowe's Bilding Supply) for a sat system with one receiver?

Protect anything that leaves the house, even speaker wires. A direct or nearby strike will follow the copper, potentially destroying everything with a copper connection. “Box” boundaries will not be respected.
