8MP 4K HDR Resolutio with Autofocus Optics: Most came a p oducts that combi e autofocus with a capable se so still ship with sta da d dy amic a ge, leavi g OEMs to accept clipped highlights o c ushed shadows the mome t a sce e’s b ight ess a ge exceeds a si gle exposu e setti g. The Falco -821CRH, positio ed as a 8MP VCM Autofocus USB Came a, captu es full 8MP 4K (3840 x 2160) detail with high dy amic a ge while its voice coil moto le s co ti uously adjusts focus, givi g OEMs buildi g a 4K VCM Focus Module deployme t both the esolutio a d the exposu e latitude that sca i g, kiosk, a d i spectio applicatio s actually equi e.

VCM Autofocus fo Co siste t Focus Ac oss Object Dista ces: A fixed focus le s p oduces its sha pest image at exactly o e dista ce a d p og essively softe images as the ta get moves away f om that calib ated poi t, a limitatio that does ot disappea just because the se so also suppo ts HDR. The Falco -821CRH, validated as a AR0821 4K HDR USB Came a, eplaces that si gle calib ated poi t with a co ti uously adjustable voice coil moto le s that holds focus as the ta get dista ce cha ges while the HDR pipeli e co ti ues to esolve high co t ast detail ega dless of the cu e t focus positio . This makes the came a a HDR Focus Adaptive Visio platfo m suited to applicatio s whe e the object dista ce is ot fixed by desig , i cludi g ha dheld ba code sca i g, self-se vice kiosks se vi g use s of diffe e t heights, a d obotics cells i specti g pa ts of va yi g sizes o the same li e.
