The following characteristics should be taken into account when choosing night vision thermal binoculars: viewing angle, objective lens diameter and magnification, module replacement, matrix parameters, and matrix frequency.
RESOLUTION
According to the adage "the higher the matrix resolution, the better the image," matrix resolution is one of the primary parameters that determines the number of thermal dots displayed. Choose professional night vision thermal binoculars whose parameters are not more restrictive than what you require for your tasks. More goals will bring about a more nitty gritty and exact picture. The picture's clarity is directly affected by the resolution.
ANGLE OF VIEW
The viewing sector is shown by the angle of view, a parameter that is determined by your requirements for a more comprehensive or detailed view of your objects. The width of the image coverage is characterized by the angle of view. The viewing angle of models with a longer range is typically smaller.
IMAGE INVERSION
The image inversion function makes it possible to precisely identify small objects on a uniform background.
THERMAL SENSITIVITY
One of the fundamental parameters that indicate the contrast between the temperatures that are known is thermal sensitivity.
Frame rate is an indicator of how dynamic the frame change on the display of the device will be. You can safely stop your choice at a minimum frequency if you do not need to observe dynamic objects.
BATTERY LIFE
It's important to think about how long you want your batteries to last. The night vision goggles thermal imaging binoculars typically last for five hours without needing to be recharged.
DISTANCE OF OBSERVATIONS
The distance of observation. The detection range and the identification range are the two parameters that need to be mentioned. The first parameter indicates the object's detection distance. The object's accurate identification distance is measured by the second value. For observation of quick targets, picking a higher goal and frequency is better.
DUST AND MOISTURE PROTECTION
The housing is protected from dust and moisture. It is advised to select models with IP 66 protection. These devices are safe to use in the rain or when there is a lot of dust: the availability of user-replaceable modules and additional equipment.
