Here's hoping I didn't just spend $200 teaching myself about polarity, or more specifically, about what happens when you roll the dice.
My security camera server setup was going ludicrously smoothly. The server build and kodicom card install took all of an hour. That should have been my first clue. I finally unpacked the security camera and universal power adapter got from Tech-home months ago, looked at it, realized the documentation didn't state what the polarity should be on the power adapter. Spent some time googling, couldn't figure it out, so I figured, what-the-heck, i'm not going to figure this out via osmosis, so I may as well try one.
Got it all plugged in, no image on the screen. Hmmm. Wonder what it could be. I jiggled all the wires, no love.
I then looked over at the wallwart, and said to myself "Hey - why isn't that green LED indicating power on anymore?". I took it out of the wall.
Oh my was it hot. Real hot. Really really hot. Not burning hot, but hot. Much hotter than power supplies are supposed to be. Did I mention it was hot?
Hey - reversing polarity may not be a good idea...
Anyhow, Radio Shack is closed now, but I'll swing by tomorrow and pick up another universal power supply.
And hope like heck that I only fried the $25 power supply, and not the $140 security camera.
