Q: Do thermal imaging devices require regular maintenance?
A: Yes, periodically check the battery, update the firmware, and
avoid prolonged exposure to extreme temperatures or vibration.
Q: What is the typical battery life of a thermal sight?
A: Depending on the model, continuous use typically lasts 12 hours.
You can carry spare batteries or use an external power source to
extend operation time.
Q: Does battery life shorten in cold environments?
A: Yes. Low temperatures reduce battery chemical activity. It is
advisable to use cold-weather adapted batteries or keep the device
in a standby state to keep it warm.
Q: When choosing a thermal sight, which is more important:
resolution or refresh rate?
A: High resolution improves image clarity, while a high refresh
rate (e.g., ≥30Hz) ensures smooth motion. Balance based on use: hunting requires
a high refresh rate, while surveillance benefits from high
resolution.
Q: What is NETD (Noise Equivalent Temperature Difference)?
A: A lower NETD value indicates the device is more sensitive to
temperature differences, resulting in higher image contrast (an
ideal value is typically <40mK).
