Image modes

VIPER 50 Next offers a variety of image modes for different environments, situations and personal preferences.

White hot

White Hot is a versatile choice for observing urban areas and shifting landscapes that displays warmer objects in white and cooler objects in black.

Black hot

Black Hot displays warmer objects in black and cooler ones in white, which makes it a preferred mode among hunters and law enforcement.

Red hot

Red Hot is a recommended mode for prolonged observation. The red-black image minimizes blue light emissions from the display and reduces eyes strain from extended usage.


The AUTO isotherm mode enables a marked object to be set as the lowest temperature object in the scene, and the other objects in the scene with higher temperatures are highlighted with yellow-red colours with graduation to this temperature threshold automatically.


The isotherm mode colors objects above the threshold temperature in different shades of red. The temperature threshold can be set (increase/decrease) by the temperature scale available.


These palettes help increase the chances for recognition & identification of the objects.


VIPER 50 Next provides clear vision to hunters in the toughest conditions by significantly improving their aim.

First-call services

Due to its technical advantages, VIPER 50 Next could easily be applied in emergency situations by policemen, firefighters, mountain rescuers, and even emergency volunteers.
