TKKOK D80 Night Vision Binoculars - Review

17 Jan 2022

The prize for the Spy Nerd contest finally made it here after a convoluted courier trek. I made an unboxing video and then realized I needed to understand it a bit better, so I did a bit of a review video.

I had fun learning how this instrument works. It performs better than I expected and has a fairly powerful zoom capability. I do not have any software that can view IR images captured by the camera yet (they have some odd format) but the captured IR videos are viewable in VLC. Overall a very interesting prize.

I think I figured it out. My batteries were a bit weak and the IR illuminator was causing a power brownout glitch while saving the IR image. This corrupted the jpeg. Running from a solid power supply everything…

Mine powered up with only 4 AA. It also appears to implement power path management and powers off the USB C port when connected to a power source.

Sometimes it forgets the IR filter isn't in the optical path on power up and the color photos look purple

Yes, mine definitely runs well off the USB C port when the batteries are depleted and even when they are not depleted. I will have to check if the two battery banks are separate with one set only used for IR illumination.

What viewer software do you use for IR images?

My IR images just show up as ordinary jpegs:

There is 500 - N, preallocated files in the photo directory, but they don't have an image extension.

I seem to have better luck garbing a video frame for an image versus taking a photo as I can pick a frame where the camera shake isn't noticeable.

My IR images have a .jpg extension, but are not readable by any viewer I have, and I have quite a few. The color images are fine on every viewer.

Not sure, there may be a FW bug buried and you happened to discover it. I noticed every image has the exact same file size. Perhaps there is a bug creating exact file size jpegs, not sure.

The IR image 2 posts up, was just drag-and-drop into chrome.

Yes, mine are all the same size as yours, but dragging into Chrome doesn't work.
