Mind blowing value - sharing the original post:

For anyone who's been on the fence about trying action cameras, I've got a worthwhile one for you that's cheap enough to be well below most people's "why not" threshold.

Behold the Topjoy TJ-5000: https://www.amazon.com/Topjoy-Sports...eywords=topjoy

As we speak, $26 on Amazon.

I got one of these in the mail yesterday and it is nearly an exact match for the SooCoo C30 cameras I've been using for the last year or so- those being really excellent $80 GoPro alternatives. There's a whole range of these cameras from different OEMs using the Novatech line of firmware and Sony NTK96660 lens and chipset. They're in the same form factor as a Gen-1 GoPro, so all generic "action camera" housings, mountings, and accessories work fine. These cameras supposedly shoot upscaled 4K and 2K at 30, but for my purposes I've always stuck with 1080/60. As mask cameras, these things have two killer features: 1. The lens is gyro-stabilized, which takes out a lot of the wobble and shake when you move, and 2. The camera puts out audible "video start/video stop" voice prompts to let you know when you're recording. When you can't see the buttons, screen, or indicator lights without taking off your mask this prompt is a real godsend.

The one drawback with these cameras is battery life, but I've gotten around this by running mine off a $8 auxiliary cellphone battery back strapped to the back of my goggle strap and connected with a USB cable- one charge of that lasts hours- I've never had it run out.

If you've got a dremel and a drill you can make your own mount out of stuff that comes with the camera.

It's $26. What are you waiting for?
