It wont damage anything. Perhaps just some dielectric grease on the ethernet connection...
Based on your other post it appears you are buying old axis cams. I hope you are getting them for really cheap otherwise you are getting screwed.
Haha! Yep, I figured I had two separate questions for two threads, but you are correct, I picked up some old Axis cameras, and yes, thankfully, I got them for dirt cheap. Irresistibly cheap.
They don't have all the fancy features of some newer gen cameras from other brands of course, but they are adequate for the job. I'm pretty low tech when it comes to what I need. And I do like the build quality of Axis. We'll see how much more life they have. I figured at these prices, it was a no-brainer to try them out. And if they fail soon, then it's not too much of a hit.
As for potentially damaging a "V" rated camera outdoors, or damaging my network, I really appreciate the feedback. I'll probably take a stab at it, and see how it goes. I think I should have one extra camera I could sacrifice to the surveillance gods and see what happens.
