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.



Anatomy of a Cheap Hong Kong Wireless Camera

It depends on which country you live in. In the USA, those eBay type "1.2Ghz" systems are often using frequencies reserved for Aircraft Navigation. So, they are illegal. Please keep in mind that even the "legal" offerings require a amateur radio (ham) license to use legally.

Just ask the seller for the Tx's exact operating freq and then consult your ham license status to see if you are allowed to operate it.

HI! im sorry to ask you more questions about this, but are the 1215 MHz and the 1.24GHz range legal? also are we still required to get a ham radio license even if the camrea is under 1000 feet range? and if we were to use a camera system that was considered to be in an illegal frequency range, would the FCC literaly pick up our signal from miles away and come and investigate even if the camera's range was 1000 feet or less or is it just considered to be an "illegal" thing? well thanks so much!!!

GOD BLESS YOU!!!!!!!!!!!!!!!!!!

Will it work?

It would be abusive to the Tx's RF amp. Especially to these minimally designed Hong Kong products.

Some Tx's may work, some might not oscillate correctly, and some would simply go poof. There is really no telling for sure. I do not recommend it, but if you need to know then you will have to try it out.

On the unit shown on the RC-CAM site, there are no provisions to hack in audio. There aren't any spare PCB pads or pre-installed components that would allow this sort of upgrade.

You have to consider that these cheap "1.2Ghz" Hong Kong systems do not readily fit the popular American design methods where one basic board is used across several products. Over there, where labor is cheap and profits are measured by low material costs, any spare part, no matter how trivial, is eliminated.

How about if you just bypass the tx altogether?

Terminate the red and black, and solder an rca to the yellow video out.

or is that what you meant already?
