GoPro vs Boscam
« on: May 27, 2016, 05:53:15 pm »
Which camera is better and why?

I measure camera quality in the following ways:

1. FPV support , can it transmit the signal easily with a widely compatible interface?Also is there FPV lag? Lag is no good for FPV because pilot can crash.
2. DVR, does it have a Digital Video Recorder and does it work well?
3. Resolution
4. FOV: The wider the better for me
5. Near Infrared Night Vision. Big plus for me because I like to fly in near darkness sometimes.

Thanks for advice in advance!

Hi!

What exact Boscam? I would not consider GoPro as a good FPV camera candidate.

1 any cam can fpv (user preference) and a cam doesnt transmit (not totaly true)! and they all use AV and a transmitter thats all there is to it, lag?? any transmission has lag but the lowist is direct transmission av-out->TX->RX->av-out.
2 again user preference -> use google or aliexpress or any other surely you can find 1 of who knows how many there are. and does it work well, and if its records  well  :-\ uuu youtube maby
3 AV output !! pal-ntsc wiki it
4 again user preference , find you lenzes for the cam your using as simpel as that
5 find a cam that can do it

I have been using my little boss cam HD19 for 3 years now NOT A SINGLE PROBLEM. I did replace the lens because it got scratched up with time. Its not as good as a gopro far as video but its does pretty good.
Do the best you can It's all you can do.

I recently ordered RunCam Split http://shop.runcam.com/runcam-split/
It offers HD recording as well as analog output for the transmitter for FPV. So with one camera you get two things and latency is similar to Runcam 3.

You can read here how much latency matters to human and what values are reasonable https://www.pubnub.com/blog/2015-02-09-how-fast-is-realtime-human-perception-and-technology/
In short anything below 50ms you can't react faster, so that is good. Differentiating between 20ms and 30ms you can consider very hard :) One can argue that flying faster = less update per part of meter, but it does not matter if brain/fingers can't react faster.

Just be aware that 10km/h = 10 000 m/h = 166.66 m/min = 2.77 m/sec so if you race at 30km/h that's 8.33 m/s. Assuming delay 100ms, which is 0.1s you get update of image every 0.833 meter each second. So you just need to be aware of this and keep safe distance. Your brain will adapt anyway and predict how to react when controlling aircraft, but good to be aware of this.  Also PAL/NTSC system has 25 FPS and 30FPS limits, which is 1/25*1000 = 40ms for PAL and 33ms for NTSC refresh rate (different thing than latency). PAL has better resolution though.

FOV depends on lens you pick. IR makes picture ugly, but go ahead and check following again RunCam brand
http://shop.runcam.com/runcam-night-eagle-astro/
http://shop.runcam.com/runcam-owl-plus/
or also decent Foxeer brand
http://www.foxeer.com/nightwolf-v2.html

These seem really good, but are FPV cameras. Usually FPV and HD recording don't come together. HD cameras usually have latency above 100ms so not suitable for flying. Except for few HD cameras that are designed to have low latency. But just read links above to make an informed decision what is better for your application.
