PVS31 Digital Night Vision, Working, IR, Square Screen

This is a digital version of the PVS31 night vision device.

We use a circuit board developed independently for this product. Even with long hours of continuous operation of the night vision unit itself, heat generation is suppressed, so we believe that there will be almost no deterioration of the battery or the unit itself.
In addition, in the case of products developed with conventional technology, even if a battery box is used, it is not possible to suppress the heat generation of the night vision unit itself, and as a result, the unit is likely to deteriorate.

As a digital night vision device, it functions properly, with the main body faithfully reproducing the real thing, including the internal wiring of the dedicated housing.

It can be seen very well even with the IR off in a park at night.
I think it will be difficult with the IR off in the mountains, forests, or indoors at night where there is no light.

Power is supplied from the battery box or the main unit. It can be used for 2 hours at maximum IR illumination efficiency.
The lens can be adjusted for refraction, so those with myopia can see without wearing glasses.

It is equipped with an infrared supplementary light (invisible to the human eye) for supplementary lighting in extreme situations.
It has waterproof performance to withstand light rain and splashes.
My personal impression is that the build quality is very solid, and the appearance feels very robust and high quality.

The resolution is 1920x1080.
