I've always been fascinated by this topic as well. As a further experiment, you may be interested to know that these IR lights can pass straight through red wine that looks totally dark and opaque to the human eye. I took some photos to demonstrate this with a DSLR with the IR filter removed here [1], but you can test this yourself by using a smartphone to look at the IR light of a TV remote with a glass of red wine in between them.

I've been pondering some sort of "night vision"[1] system for my car after noticing how excellent low light is on my VIOFO dash cam.

The dash cam has a video-out port, but unfortunately it appears to be NTSC resolution. I'd love some sort of setup that outputs to >=8" 1080p display attached to my dash. It would help so much in my rural area with wildlife in the road, as well as the constant random pedestrian walking on an unlit rural highway in dark clothing.

Ideally, if I could get great quality, low noise low light video like the VIOFO, I could then start playing with object identification with OpenCV.

1. I worked on such spectral systems in a past military life but don't want to attach something big like a Cadillac FLIR unit, or something expensive, like nearly every viable consumer FLIR option. All the "affordable" consumer FLIR options suffer from low resolution and/or low response time.

When I experimented with connecting two thermal cameras to a VR headset for stereo thermal vision, I used two Seek CompactPRO FastFrame units. They're 320x240@15Hz for $400 which is a lot more usable than the typical 80x60@9Hz consumer thermal, and it's easy to integrate the Android model into custom applications. They also have a 320x240@25Hz model for $1000.

I'm still impatiently waiting for affordable 640x480 thermal cameras, but in my opinion 320x240 at moderate frame rate is past the good-enough threshold to be legitimately useful for high contrast situations like identifying warm-blooded life on the side of a rural road.

The Tesla Cybertruck has an option to display the view from the front bumper camera on the 18.5" main screen, but front camera display is unfortunately not available in any of Tesla's other models. With the proliferation of large touchscreens and camera arrays, more vehicles may support this from the factory soon.
