Technical parameters guide
A clear explanation of the most important technical parameters of thermal imaging and optics. Find out what NETD, sensor resolution and IP protection mean.
SENSOR / DISPLAY
Temperature sensitivity (NETD)
Indicates the device's ability to distinguish small temperature differences; the lower the value (e.g.
<20 mK), the more detailed and contrasty the image.
VOx sensor type
A type of thermal sensor used in modern thermal imaging; provides high sensitivity and image stability.
Thermal sensor resolution 640 × 512 px
The number of sensor pixels; higher resolution means more detail and better target recognition at greater distances.
Thermal sensor resolution 384 × 288 px
Medium resolution level suitable for general use and shorter distances.
Sensor pixel size (in µm)
The distance between individual pixels on a sensor; a smaller pixel allows for more compact optics and better detail.
Image refresh rate (Hz)
The number of frames per second; a higher frequency (e.g. 50 Hz) provides a smoother image when moving.
Infrared spectral range (µm)
The range of wavelengths that the sensor can capture; typically 7–14 µm for thermal detection.
Display type AMOLED
A modern type of display with high contrast and rich colors, suitable for difficult lighting conditions.
Display type OLED
High contrast display with low power consumption.
Display type LCOS
A type of digital display used mainly in night vision; it provides a fine image with good resolution.
Display resolution
It indicates the number of pixels on the screen; higher resolution means a sharper resulting image.
OPTICS
Lens focal length (mm)
Determines the basic magnification and range; a higher value means greater zoom and a narrower field of view.
Lens aperture (e.g. f/1.0)
Indicates the lens's ability to transmit light or infrared radiation; a lower number means better performance in low light conditions.
Field of view
The width of the area visible in the image; a wider field provides a greater overview, a narrower one provides greater zoom.
Dioptric correction
Possibility of adjusting the user's vision image without the need to wear glasses.
Digital image magnification
Software zooming of the image; increases magnification but may reduce the quality of detail.
Optical magnification
The actual zoom achieved by the lens without loss of image quality.
PERFORMANCE / RANGE
Detection distance
The maximum distance at which the presence of an object can be detected.
Recognition distance
The distance at which the type of object (e.g., human or animal) can be determined.
Identification distance
The distance at which a specific target can be accurately determined.
Integrated laser rangefinder
A device for accurately measuring the distance to the target directly in the optics.
Ratiometric rangefinder
A function that allows estimating the distance of a target based on its known or assumed size in the image; the user sets the reference height of the object and the device calculates the approximate distance based on the proportions in the field of view.
Laser class
Safety classification of laser rangefinder according to standard.
NIGHT VISION / INFRARED ILLUMINATION
Infrared illumination
Invisible infrared light allowing observation in complete darkness.
Laser infrared illumination
A more powerful type of illumination with a more precise beam and greater range.
Infrared wavelength 850 nm
Stronger infrared light with longer range, slightly visible when viewed from the front.
Infrared wavelength 940 nm
Less visible infrared light, suitable for discreet observation.
Digital night vision
Technology using a digital sensor instead of a classic image intensifier.
IMAGE TECHNOLOGIES
Real Estate+
Advanced image processing aimed at increasing naturalness, contrast and detail to make the image appear more realistic and readable.
Vision+
Image optimization technology that improves brightness, contrast, and sharpness in poor lighting or temperature conditions.
Intelligent Shutter-Free Correction (HSIS)
Sensor calibration system without the need for a mechanical shutter, which ensures a smooth image without the typical "freezing" during correction.
Magic ZOOM
A software digital zoom algorithm that minimizes quality loss and preserves more detail than conventional digital zoom.
ZOOM PRO
Improved digital zoom using advanced image processing to maintain sharpness and contrast at higher zoom levels.
Image PRO 3.0
The latest generation of image processing algorithm that improves noise reduction, detail rendering and overall thermal image clarity.
RESISTANCE / CONSTRUCTION
Protection level IP66
Complete protection against dust and resistance to strong water jets from all directions.
IPX6 protection level
Protection against strong splashes or jets of water, with the marking "X" indicating that the degree of protection against dust is not specified.
Protection level IP67
Complete protection against dust and protection against temporary immersion in water (typically to a depth of 1 meter for approximately 30 minutes).
IPX7 protection level
Protection against temporary immersion in water (typically to a depth of 1 meter for approximately 30 minutes), with an "X" indicating that dust protection is not specified.
