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.
The seller at RangeVideo reznikvova stated that DX201 has a global snap shutter instead of a rolling shutter, basically it processes frames differently. Though i did not know it is a CMOS sensor... I found this here
That's right DX201 is neither CCD nor CMOS. It uses new DPS technology that surpasses CMOS and CCD technologies in image quality, dynamic range, exposure... You can read more about the DPS HERE. I don't know what the rolling shutter effect is, but i'd assume it does not have it. I've ordered this camera from RangeVideo and should be getting it this week, hope i won't be dissapointed since it's not cheap... I can check for rolling shutter effect when i get it...
Thanks for explanation, i understand what you mean... Anyway i'm looking for a new system already but i can't decide which one of these would be better for me: Combo Set Receiver +Transmitter 1.2Ghz 1000mW Combo Set Receiver +Transmitter 900Mhz 500mW I'm afraid that 1000mW may seriously start to interfere with airplane's or (helis) receiver at long range even if it's tuned to 40MHz, because there is little space to put them far enough apart, you think that could happen ? Also can you tell me what would be the effective ranges of those systems, and of 40MHz RC ?
the short circuit is in the receiver. Ok i guess it's meant to be that way but it just didn't make sense to me how can ground be in direct contact with antenna. This high frequency RF stuff is very strange and confusing... But what else could be the reason for such bad performance... I read on this forum some got 300 or more meters of range with 10mW. Which means this 200mW should be at a very minimum twice as that with stock antenna and everything...
Hello everyone! I have this wireless video system for about a year now, the range is very short (picture starts fading at 220m). But only recently i have discovered what i think is the problem, the antenna of the receiver is in complete short circuit with the ground and it's factory made that way! I found a very tiny about half a milimeter wide and 1cm long connection between the antenna and ground on the circuit.... This is not right is it ?
