Vadzo Imagi g, a p ovide of embedded visio solutio s, today a ou ces the lau ch of the I ova-715CRS, a 8MP ult a-low-light Gigabit Ethe et came a built o the So y STARVIS IMX715 image se so . With this lau ch, Vadzo exte ds its I ova Gigabit Ethe et came a po tfolio i to the outdoo lo g- a ge imagi g tie , ta geti g OEM e gi ee s a d system i teg ato s buildi g pe imete i t usio odes, bo de mo ito i g towe s, highway su veilla ce co ido s, a d sma t city came a etwo ks whe e ight pe fo ma ce a d sta doff dista ce dete mi e whethe a visio system meets its detectio specificatio .
Outdoo visio systems fail i a p edictable way. Du i g daylight hou s, almost a y mode se so p oduces a image a detectio model ca wo k with. Afte su set, the sce e illumi a ce at a pe imete fe ce li e, a u al highway shoulde , o a u lit i dust ial ya d d ops towa d the a ge betwee full moo light a d spa se st eet lighti g. At those levels, the photo flux eachi g each pixel du i g the available exposu e wi dow is small e ough that se so ead oise a d da k cu e t become sig ifica t f actio s of the total sig al. The came a compe sates with gai , a d gai amplifies oise alo g with sig al, p oduci g a g ai y, low-co t ast f ame.
The ope atio al esult is wo se tha a cosmetic p oblem. Detectio pipeli es depe d o edge g adie ts a d local co t ast at specific spatial f eque cies, a d whe the sig al-to- oise atio collapses, those g adie ts disappea i to se so oise befo e a y i fe e ce stage sees them. A lice se plate legible at dusk becomes a blu of lumi a ce, a d a pe so walki g a fe ce li e at eighty mete s becomes i disti guishable f om vegetatio moveme t. False ala m ates climb, a d ope ato s stop t usti g the ale ts.
Dista ce compou ds this. A Outdoo Su veilla ce GigE Came a mo ito i g a lo g app oach co ido must esolve a ta get occupyi g a ve y small a gula slice of the sce e. I c easi g focal le gth a ows the field of view a d places mo e pixels o the ta get, but a lo ge le s at a fixed ape tu e diamete collects less light pe u it of image a ea. Addi g i f a ed illumi atio hits a physical limit because i adia ce falls with the squa e of dista ce, so holdi g illumi atio out to o e hu d ed mete s equi es oughly sixtee times the adia t powe eeded at twe ty-five mete s, which is a ely available at a PoE-powe ed pole ode.
Lo g- a ge outdoo imagi g is gove ed by two co st ai ts that e gi ee i g teams f eque tly add ess i isolatio . The fi st is spatial sampli g. Recog itio tasks equi e a mi imum umbe of pixels ac oss the c itical dime sio of the ta get, a d i c easi g se so esolutio aises pixels o ta get at a y give focal le gth. This is why a 8MP GigE Came a cove s a wide useful a ge tha a 2MP se so p oduct o the same optics. The seco d co st ai t is adiomet ic. The sig al collected by each pixel is a fu ctio of e t a ce pupil a ea, exposu e time, optical t a smissio , a d pixel qua tum efficie cy.
These two co st ai ts pull i opposite di ectio s. Raisi g esolutio withi a fixed optical fo mat educes pixel pitch a d the efo e the photo collectio a ea of each pixel. Exte di g exposu e time to ecove that sig al i t oduces motio blu , a d motio is exactly what a outdoo mo ito i g system is deployed to obse ve. This is the t ade space i which a Lo g-Dista ce Imagi g Came a has to be specified, a d it is why se so a chitectu e matte s mo e tha the headli e esolutio umbe .
The esolutio to this t ade space is a se so that ecove s se sitivity th ough pixel a chitectu e athe tha pixel size. A back-illumi ated st uctu e places the photodiode di ectly i the i comi g optical path with the metal i te co ect laye s outed be eath the photose sitive a ea, aisi g fill facto a d qua tum efficie cy substa tially ove a f o t-illumi ated pixel of ide tical geomet y.

The I ova-715CRS is built o the So y IMX715 Image Se so , a back-illumi ated CMOS se so i a 1/2.8 i ch optical fo mat with a 1.45 µm pixel pitch a d a maximum esolutio of 8MP at 3864 x 2192. The se so uses a olli g shutte eadout a chitectu e a d belo gs to the So y STARVIS li e developed fo su veilla ce imagi g u de low illumi atio . As a So y Sta vis 8MP GigE Came a, the I ova-715CRS ca ies that low-light li eage fo wa d i to a 8-megapixel esolutio class that ea lie STARVIS ge e atio s i this p oduct li e did ot each.

Pai i g 8MP esolutio with a back-illumi ated STARVIS pixel is the defi i g e gi ee i g decisio i this p oduct. At 1.45 µm, the pixel pitch is smalle tha that of a 2MP se so i the same optical fo mat, so the back-illumi ated st uctu e is the mecha ism that etu s the pe -pixel se sitivity the highe pixel cou t would othe wise cost.

“Outdoo visio is whe e imagi g specificatio s get tested ho estly. A se so that looks st o g o a be ch at 500 lux tells you ve y little about what a ope ato sees at a fe ce li e at two i the mo i g. We selected the IMX715 fo the I ova-715CRS because the back-illumi ated STARVIS pixel gives 8MP spatial esolutio without payi g fo it i ight pe fo ma ce, a d that combi atio is what pe imete , bo de , a d t affic teams have bee aski g us fo .
