Night vision technology is a capability to see in environments with low levels of light or even in complete darkness. This is usually achieved through the use of image intensification technology, thermal imaging, or infrared illumination.
Night vision equipment typically consists of specialized optics that can amplify the available light, or detect infrared radiation emitted by objects. Image intensification technology, for example, works by converting low levels of ambient light into visible images.
In terms of whether a specific device has night vision functionality, you would need to refer to the product specifications provided by the manufacturer. Look for key features such as "low-light sensitivity", "infrared capability", or mentions of specific night vision technology like image intensification or thermal imaging.
In summary, the presence of night vision functionality in a device depends on the specific technology it uses to see in low light conditions, and this can be confirmed by reviewing the technical specifications of the product.
