onick NV8000 3D Night Vision Goggles Binoculars Rechargeable Flip-up Scope Tactical Grade Helmet Mounted Goggles, with excellent performance, small size, light weight, clear imaging, simple operation, flexible use, and the magnification can be changed by replacing the objective lens (or connecting the multiplier). The night vision device has built-in infrared auxiliary light source and automatic anti-glare protection system. It is highly practical and can be used for military observation, border and coastal defense reconnaissance, public security surveillance, evidence collection, customs anti-smuggling, etc. in the night without lighting environment. It is an ideal equipment for public security departments, armed police forces, special police forces, and guard patrols.

1. Active infrared night vision device

Active infrared night vision device is a night vision device that uses infrared to illuminate the target and then receives the reflected infrared signal to perform imaging. Because it can actively illuminate the target, it can also achieve better imaging effects in low light or complete darkness. Compared with passive infrared night vision devices, active night vision devices have a longer imaging distance and clearer images. However, this type of night vision device requires batteries, so it is more consumable.

2. Passive infrared night vision device

Passive infrared night vision device is a night vision device that uses infrared radiation emitted by the target itself to perform imaging. Because this type of night vision device does not need to emit infrared rays, it is more power-saving and has a longer service life. However, passive infrared night vision devices need to work when the infrared rays emitted by the target are strong enough, and poor imaging may occur when the conditions are not sufficient. In addition, in long-distance scenes, the imaging effect of passive infrared night vision devices is not as good as that of active night vision devices.

In summary, active infrared night vision devices and passive infrared night vision devices each have their own advantages and disadvantages, and the choice depends on the specific usage scenario and needs.
