Termovizijske naprave, termovizijske kamere in termovizijski daljnogledi – pogosta vprašanja

1. Kaj je termična naprava?

A thermal device detects heat (infrared radiation) emitted by objects and converts it into a visual image known as a thermogram. This technology allows you to clearly see temperature differences, even in complete darkness and through light foliage, smoke, or mist.

2. What is the difference between a thermal camera and a thermal scope?

Thermal Camera

  • Designed for handheld use

  • Ideal for inspections, search & rescue, security, wildlife observation, and outdoor activities

  • Not intended for mounting on firearms

Thermal Scope / Thermal Riflescope

  • Designed to be mounted on a rifle or firearm

  • Includes aiming reticles, ballistic features, and shooting-specific functions

Both use the same core thermal technology, but thermal scopes are built for accuracy and recoil resistance.

3. What do NETD and resolution mean?

NETD (Noise Equivalent Temperature Difference)

  • Measures thermal sensitivity

  • Lower NETD (e.g. <30 mK) means better contrast, more detail, and clearer images

Resolution (e.g. 256×192, 384×288, 640×512)

  • Higher resolution provides sharper images and better target recognition at longer distances

Both NETD and resolution play a critical role in overall image quality and effective range.

4. Do thermal scopes work in daylight?

Yes. Thermal optics work equally well day and night. Because they detect heat rather than visible light, they perform reliably in bright daylight, total darkness, fog, smoke, and light vegetation.

5. What factors affect detection range?

Detection range depends on several factors:

  • Sensor resolution and sensitivity

  • Lens size and optical quality

  • Weather conditions (temperature, humidity, rain)

  • Target size and heat signature

Higher-end sensors and optics provide longer detection ranges, but real-world conditions always influence performance.

6. What should I consider when choosing a thermal scope?

Key features to consider include:

  • Sensor resolution

  • Lens size (larger focal length = longer range)

  • Base and digital magnification

  • Integrated Laser Range Finder (LRF)

  • Ballistic calculator

  • Display quality and refresh rate

  • Video and photo recording

  • Wi-Fi and mobile app support

  • Battery type and operating time

The right choice depends on your intended use (hunting, security, observation, inspection).

7. What is a Laser Range Finder (LRF)?

An integrated Laser Range Finder measures the distance to your target and displays it on the screen. This is essential for accurate shot placement and advanced ballistic calculations.

8. How important is the frame rate (Hz)?

A higher frame rate (such as 50 Hz) delivers smoother image movement, which is especially important when tracking moving targets.

9. Can thermal devices record video and photos?

Yes. Most modern thermal scopes and cameras feature built-in photo and video recording, internal memory, and often Wi-Fi streaming to smartphones or tablets.

10. How long does the battery last?

Battery life varies depending on usage and ambient temperature. Most premium thermal devices provide 8–12+ hours of operation. Many models also support external power banks via USB.

11. Are thermal devices waterproof?

Yes. Most quality thermal devices are rated IP66 or IP67, meaning they are protected against rain, dust, and harsh outdoor conditions. Always refer to the specific product specifications.

12. Can thermal devices see through glass?

No. Thermal sensors cannot see through glass. Glass reflects infrared radiation and blocks thermal imaging.

13. Can thermal scopes be used for hunting?

Yes. Thermal scopes are widely used for hunting predators, pest control, and nocturnal game. Always ensure compliance with local hunting laws and regulations.

14. Do thermal devices replace night vision?

They serve different purposes:

  • Thermal detects heat and excels in darkness and camouflage

  • Night Vision amplifies available light and provides more natural visual detail

Many users combine both technologies depending on conditions.

15. What is the difference between optical and digital zoom?

  • Optical zoom uses the lens and maintains image quality

  • Digital zoom enlarges the image electronically and may reduce clarity

For long-range identification, optical zoom is preferred.

16. How should I maintain my thermal device?

  • Clean the lens only with proper lens-cleaning tools

  • Do not touch the thermal sensor

  • Store the device in a protective case

  • Keep batteries charged and dry

  • Avoid prolonged exposure to extreme temperatures

Proper maintenance ensures long service life and optimal performance.
