Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

I used a MAX4222, and made a board that was easy to power either by 5V or 7-12V, and had RCA plugs but still could be cut to a much smaller size for use onboard using solder pads instead of plugs. There's a jumper to select between 2 2-way buffers or 1 4-way one.

Note that I skipped the video AC coupling caps on the inputs and outputs, knowing that all my video equipment had those on their side, so I could save a bit of space for when used onboard. It's not the case with all video equipment, so to do things correctly you'd add those.

I only made 2 and have now cut them to the "onboard" size, and use commercial units with a nice metal case for my ground equipment. One of them was used in a broadcast setup once ;)

The video signal would be connected to 2 75 ohm inputs which is 37.5 ohm. The will pull the video signal lower than it should be giving a dark picture. It can also give other problems depending on the equipment used.
