Need help buying a 4K cam

[P38]

Hi, new to the forum, based in Cyprus.
I need help buying a very good quality 4K camera for recording long hours of footage.
I need the camera for recording nature. Stabilization is not an issue, as i will be using a tripod, the camera will be stationary.
Audio is also not an issue, as i will be recording using another device, but it would help save card space if i could disable the audio recording completely.
Video quality (4K/30fps) and not overheating are my most important concerns. Also, a narrow fov, about 90 degrees, I already have the samsung gear 360 (2016 model) shooting with only 1 lens,
but the fisheye lens makes the footage unusable.
I am between the YI 4K+ , the YI 4K and the ThiEYE T5e.
Do you have any other suggestions?
Thank you.

90 degrees - yes
no overheating - yes
audio - will record anyway.
customised/improved firmware - available in a thread on this forum.
Super capacitor version for really hot conditions - available soon.

Thanks Nigel, first i hear about this camera, but the footage i found on youtube is amazing.
And on paper looks very good also, processor, sensor, lens. I will check the reviews, but it looks much better than the Yi or t5e.
Thanks.
