Observations
THE SAME F/1.1 APERTURE, BUT THIS TIME THE NETD IS SPECIFIED AT F#=1.1 — a consistency worth noting by contrast with the already-covered HIKMICRO Pocket2 and InfiRay P2 Pro in this comparison, where the lens's real aperture doesn't match the advertised NETD conditions. Here, at least on paper, the two values line up.
Part of the same range as the already-covered HT-A1 in this comparison, whose own notes already flagged a recurring mix-up between the thermal sensor's resolution and the visible camera's resolution for this brand; this particular model could be verified as consistent on that point.
