Hi Jim
You asking me yesterday which equipment I use.
I made my own system. I buy cam from Black Widows, the old CX161 and new KX121, I made a metal case to protect it. Two wide angle lens (105 deg.) are use. For the video TX/RX, I use Felsweb or Airwave module, I had few parts, connector and case.
I made a web site two years ago, you will find info about my setup, check "miscelleanous" to find technical info:
