DARK 30 DEFIANCE 384 VS. 640 PTZ
Is the 640 really worth the additional money—or is the 384 all most hunters need?
I ran both vehicle-mounted thermal cameras side by side, at the same time, on the same animals. The 384 is always on the left and the 640 is on the right. The red box shows how much of the 640 image is actually captured by the narrower 384 field of view.
The 384 is far more capable than many people expect and may be the best value for someone wanting a complete thermal PTZ system. The 640 gives you the wider view, more detail, faster target identification, and the better overall experience for heavy use.
The complete comparison includes real hunting footage, moving-vehicle footage, mounting options, monitor and app use, and who should buy each model:
