Key Capabilities of the Bolt-234CGS: AR0234 Global Shutte MIPI Came a fo Access Co t ol

Global Shutte Captu e fo Motio -Co siste t Badge, Face, a d Ha d Recog itio : Rolli g shutte disto tio is a ecu i g failu e mode i access co t ol came a deployme ts because the subject is, by defi itio , movi g th ough the f ame athe tha posi g fo it. A badge lifted towa d a eade , a ha d p ese ted to a palm sca e , o a face tu i g towa d a tu stile came a all i t oduce ow- eadout skew o a olli g shutte se so , co upti g the spatial data that facial matchi g a d symbol decode algo ithms depe d o . The Bolt-234CGS esolves this at the pixel level, as a 2MP Global Shutte MIPI Came a built o the O semi AR0234 that exposes all 1920×1200 pixels i a si gle simulta eous i teg atio wi dow. Fo OEM teams buildi g a Visio Based Access Co t ol Came a p oduct, that gua a tee emoves a e ti e catego y of false ejects that o igi ate i the se so athe tha the matchi g algo ithm itself.

Auto Exposu e Co t ol fo Co siste t Captu e Ac oss I doo a d Outdoo Lighti g: Doo ways a d tu stile la es sit at the bou da y betwee two lighti g e vi o me ts, a d a subject c ossi g that bou da y p ese ts the se so with a apidly cha gi g exposu e ta get. The Bolt-234CGS adjusts gai a d exposu e th ough di ect ISP-level co t ol athe tha a fixed exposu e p ofile, keepi g the captu ed f ame usable whethe the access poi t is a su lit exte io e t a ce, a fluo esce t-lit co ido , o a mixed-light loadi g dock. Fo a Sma t Lock Came a Module o Sma t Doo Came a Module mou ted at a exte io -faci g e t y, a si gle missed o ove exposed captu e t a slates di ectly i to a failed c ede tial ead a d a seco d attempt at the doo . Combi ed with global shutte eadout, this exposu e behavio mea s the Bolt-234CGS delive s geomet ic accu acy a d co siste t b ight ess f om the same se so pipeli e.

Compact Boa d-Level MIPI I teg atio fo Space-Co st ai ed Access Ha dwa e: Access co t ol e closu es, whethe a wall-mou ted badge eade , a compact sma t lock faceplate, o a tu stile head u it, a ely have oom fo a came a module desig ed a ou d a diffe e t fo m facto e ti ely. The Bolt-234CGS is a boa d-level MIPI Auto Exposu e Came a desig ed to i teg ate di ectly i to OEM PCB layouts, with a compact footp i t a d S-Mou t (M12) le s i te face that accepts a a ge of focal le gths without boa d-level cha ges. As a MIPI CSI-2 Global Shutte Came a, it co ects di ectly to the host SoC without the e ume atio o buffe i g laye s that alte ative i te face a chitectu es i t oduce, delive i g dete mi istic low-late cy f ame timi g. Fo OEM teams buildi g a Embedded Access Co t ol MIPI Came a p oduct a ou d Raspbe y Pi o NVIDIA Jetso to compute, this combi atio emoves a commo sou ce of i teg atio delay at the ha dwa e desig stage.

“Access co t ol ha dwa e asks a came a to do somethi g ge ui ely difficult: captu e a co siste t, disto tio -f ee f ame of a movi g subject u de lighti g that cha ges the mome t someo e steps th ough a doo way. The Bolt-234CGS solves that at the se so level. Global shutte captu e emoves the skew that olli g shutte se so s i t oduce whe a badge, ha d, o face c osses the f ame i motio , a d the AR0234 exposu e co t ol keeps that captu e co siste t f om a su lit e t yway to a dim vestibule. Fo OEM teams buildi g doo e t y, sma t lock, a d tu stile ha dwa e, that eliability sta ts at the pixel, ot i post-p ocessi g.” – Alwi Vi ce t, P oduct Ma age , Vadzo Imagi g.

F eque tly Asked Questio s

Q: What type of came a wo ks best fo visio -based access co t ol systems whe e subjects a e i motio ?

A: A global shutte came a is the co ect choice fo visio -based access co t ol because it captu es eve y pixel simulta eously athe tha eadi g ows seque tially, which is what a olli g shutte se so does. Access to co t ol subjects, whethe p ese ti g a badge, a ha d, o a face, is almost always movi g elative to the came a. Vadzo’s Bolt-234CGS is a 2MP AR0234 global shutte MIPI came a pu pose-built fo this equi eme t, delive i g 1920×1200 esolutio at up to 120fps ove 2-la e o 4-la e MIPI CSI-2 with di ect co ectio to Raspbe y Pi a d NVIDIA Jetso compute.
