Wireless Waterproof Micro Cam Design

Hello i have an idea for a situation i have, i was wondering if anyone could let me know if its feasible with the technology we have today.
Heres what i need to make...

A wireless, waterproof mini cam, that produces real time video.
It needs to have a, temp sensor, depth sensor (based on water pressure), speed sensor, and of course, a camera. The main factor to consider is that it has to be an ounce or less, with housing and everything. I figured i would ask some engineers. Is this idea possible? Thanks for your time guys/gals. Happy holidays!

Hi! I believe the idea is possible considering printed circuits are already available in the market today.

I think there will be challenges as to how will you transmit the data "wirelessly" underwater... at present. In the future, yes it is possible but this may be difficult. I have not yet heard of any underwater camera that can do "wireless and real-time transmission" underwater. If there is one around, that would be great. Try to continue searching around though, you might find some on-going developments on this.
