Question: Cheap, lightweight GoPro alternatives for aerial mapping?

I suggest you try aliexpress.com instead of Amazon -- why pay double or more money for stuff when you can buy it direct from China? They are an umbrella for many different sellers. And they have a decent customer support procedure if, as sometimes happens, something you buy doesn't make it all the way across the Pacific. Delivery can be very slow.

Here is a strange development. This action camera has a 1MP sensor. It is a 1/4" sensor which has an area of 10 square mm. The native image size is 1280 x 800 pixels, but it is described as having "5.0 Megapixels." It costs $24.99 from Amazon and looks just like all the other actioncams. https://www.amazon.com/dp/B01HJ8FJSS/ref=dra_a_rv_bb_ho_xx_P3159_100

Hi Chris - yeah i would be surprised if it's actually different, these almost all seem like the same hardware in different cases. I have found some deals from time to time on this type of camera for <$30; could be worth buying to see, at that price.

I Liked recently launched Eken H6S 4K Action camera, on YTECHB

Just noting that @csik has had trouble with some of these types of cameras recently:

I chocked it up to not being familiar with the cameras but found it odd that when we took them down they always seemed to be off.

After trying to get to know them a bit better, it seems they are just really flaky. Even with a full charge they seem to turn off all the time, and one is now stuck in permanent startup screen... the surfer's longest ride. It's getting a bit rough as a couple of times now we've done major sessions with people only to have nothing to show. So I wanted to ask:

1) has anyone successfully done a firmware upgrade or such to improve the performance? 2) has anyone brought a frozen camera back to life? We've tried all permutations/combinations of memcard, battery, powered on with different buttons, etc. We can't really risk any more failed sessions, so I'm probably heading out to some camera stores now. 3) are there any models / families you'd recommend?

That's it really, except I'd be hesitant to recommend these to anyone. Neither worked well and one pretty much died after a single flight. Not complaining, just looking for help and wondering if you have recommendations.

I checked a clone or similar on amazon and it looks like 25% give one star because of bricking.

Good news though. I stuck the memory card in my laptop and one of the sessions was fully documented. The camera stopped recording before we brought the kite down, so it was off when it arrived, and none of the photos showed up. Which correlates with what we noticed previously, that it really only works on a full charge, then things start getting weird. Like, with two bars remaining it will do 3 or 5 photos on continuous then just stop and go black, only allowing a reboot when the battery is removed. Then it will go back on, but just repeat. So when we rebooted it it would read any of the recent photos.

So it looks like it works from about 3 bars to 2, or so, then gets unpredictable. No brown-out detection? Pretty weird. And the other is just bricked on the welcome screen. But I guess at least we have a second battery! ;)

I love GoPro, and I am following up to the question as I do want to know for some alternatives to it for aerial mapping. I have already been reading a lot about GoPro. Recently I come accross about Fish eye effect, and that is a great feature of it. Though someone mentions about removing Fisheye effect from GoPro using Photoshop, I want to know how can we do it in the gopro itself?

Thanks Warren :)

We are getting amazingly good results using the miSphere 360 camera. due to the gyroscope and other sensor, post-processing using their standard software, we get a super stable image staying on the same view throughout the video, whatever shaking is re-calcutated to create stable videos. https://www.hackteria.org/wiki/PA18_Off_Ground_-_Fly_High
