Good day, I have been trying to find an analog (NTSC) camera that is small in size and can do sports action (Analog Go pro equivalent). The reason for this is simple, the infrastcture currently in place is old analog and is not compatible with any digital systems. To add insult to injury, the cabling is all coax that goes through the slip ring thus I can not use HDMI or anything of that matter. Is there any solid analog cameras still out there?
