SUMMARY

TV cameras, including inexpensive camcorders, are equipped with autofocus systems, enabling automatic focus adjustments. In contrast, USA tanks do not possess alarm systems to detect targeting by passive infrared (IR) systems, as passive IR technology does not emit signals that can be detected. The discussion highlights the limitations of passive IR detection, emphasizing that it operates on low-frequency light, making it undetectable to the target.

PREREQUISITES
  • Understanding of autofocus technology in cameras
  • Familiarity with infrared (IR) systems and their classifications
  • Knowledge of military technology and systems
  • Basic principles of light frequency and detection
NEXT STEPS
  • Research the specifications and capabilities of autofocus systems in modern cameras
  • Explore the differences between passive and active infrared systems
  • Investigate military technologies related to target detection and tracking
  • Learn about the implications of IR technology in surveillance and defense systems
USEFUL FOR

Military technology enthusiasts, camera operators, and professionals in defense systems who seek to understand the functionalities of autofocus in cameras and the limitations of infrared detection in military applications.

do TV cameras have autofocus?

and, do USA tanks have some alarm system telling them if they are been targeted with an IR system?
 
Computer science news on Phys.org
Hmmm... well, there is no way to tell if you are being targetted with a passive IR system. Active IR, I don't know, but I would guess probably not.

These sites are excellent sources of military/technological info; let me know if you can find anything there:

Yes, tv cameras have autofocus (just like the cheap camcorders do).

No, since IR is completely passive, there is no way to tell if you have someone tracking you. Remember, IR is just low frequency light. You can't tell if someone is looking at you.
