I was interested in the "GoPro Knockoff" mentioned in the video. It's an Akaso 5000 series. Akaso now has a 7000 model for $70. I'm very curious about this product! Not much info about storage media compatibility. Can anyone comment?
Aside from that, they came with a bunch off accessories, including a non-coded remote that allows "one button" picture or video taking, without caring about the mode of the camera (and the buttons on the remote are easier for kid hands to press, less force needed)
The non codedness comes in handy, since one remote will trigger both cameras, allowing synchronized videos to be created for front/rear or stereoscopic purposes.
btw, created an account to post this, hope it has value.
At that price, you could afford to buy five of them and the micro computer to amalgamate the camera output into something better than bad.
