Frequently Asked Questions
How Long Does Thermal Calibration Take on FLIR Drones?
Thermal calibration on FLIR drones typically takes 30-90 seconds. You’ll notice your drone performing this process automatically during startup or when significant temperature changes occur. Higher-end models calibrate faster than budget options. Don’t interrupt this vital process—it guarantees accurate temperature readings and clear thermal imagery. Some advanced FLIR systems feature “continuous calibration” technology that works in the background without pausing your flight operations.
Can FLIR Drones Detect People Through Walls or Dense Foliage?
No, FLIR drones can’t see through walls. Thermal imaging detects heat signatures on surfaces, not through solid objects. You’ll find they can partially penetrate light foliage by detecting heat differences, but dense vegetation blocks thermal radiation.
