Ngokwengxelo yenkampani ye-IHS izixhobo zokujonga ividiyo zenze igalelo nge-11.9 yezigidigidi zeedola zaseMelika kurhwebo lokhuseleko lwehlabathi kwi2012. Kwaye eli nani liyakhula minyaka le. Inkqubo yokubeka esweni imboni yezokhuseleko ivela kwi-CCTV, ilandelwa ukuhanjiswa kwesiginali ye-CVBS yevidiyo yerediyo kunye nomgangatho weenkqubo zikamabonwakude, kwaye inkqubo yosasazo lwevidiyo esemgangathweni mayibe sisalathiso okanye iphuculwe kweminye imiba yezobugcisa. Yiyo loo nto xa umzi mveliso wezokhuseleko ujikile kwividiyo ye-SD yaya kwividiyo ye-HD, ngokwendalo zoba usasazo lukanomathotholo kunye nomabonwakude. Ukuza kuthi ga ngoku, njengoko iteknoloji ikhula, ixabiso leekhamera eziqhelekileyo ze-analog linciphise kakhulu kwaye lavula imarike yoluntu kwaye yonyusa ibango. Kwelinye icala, izixhobo ezinkulu zokujonga ividiyo ziyafuneka kwimfuno yokujonga ephezulu kwaye zenze izixhobo zokubeka iliso ezikrelekrele HD-SDI kunye Iikhamera ze-IP ze-IP zaba yintandokazi entsha.
Isilayidi esisebenzayo sihamba ngeendlela ezimbini ezijikelezayo ukufezekisa umqondiso kunye nokuhanjiswa kwangoku ukusuka kwindawo emileyo ukuya kwindawo ejikelezayo. Njengengxenye ebalulekileyo kuyo nayiphi na into efuna iikhamera ezijikelezayo ezingama-360 eziza kugqithisa yonke imiqondiso / idatha / amandla ukusuka kwicala layo elimileyo liye kwicala elijikelezayo, iringi yokuhambisa isiliphu iyafuneka ukuba nayo isebenze ngaphezulu. I-AOOD ijolise kumacwecwe okushenxisa ukusukela ngo-2000 kwaye ijonge kakhulu kuphuhliso lweshishini lokhuseleko lonke ukuze ifunde isidingo sabathengi ngexesha lokuqala. Ukusuka kwentsusa iingcingo ezi-6 ezihambelana nekhaphethi yesiringi yesiringi SRC22-06 ye-CCTV ukuya kuthi ga kwi-HD kunye ne-Ethernet yokurhangqa amakhonkco ee-HD-SDI kunye neekhamera ze-IP ze-IP, i-AOOD ihlala ingqamene nabaxhasi kunye nentengiso.
I-AOOD Ethernet slip rings ixhasa i-1000 Base T kwaye isetyenziswa ngokubanzi kwiikhamera ze-HD ze-IP nakwiikhamera zewebhu. Iitshaneli ze-Ethernet kunye ne-SDI ijelo linokufakwa kwiyunithi enye yesilayidi esine-compact. Itekhnoloji ye-HD-SDI isebenzisa intambo ye-coaxial ukuhambisa inkcazo ephezulu yokuhanjiswa kwevidiyo yedijithali ebonakaliswa ngokuphucula eyona nkqubo iphambili yevidiyo ye-analog, zombini ukuqinisekisa ukuhanjiswa okuthembekileyo kwenqaku levidiyo ukuya kwindawo enokuqhubeka nokusebenzisa kwakhona i-analog yevidiyo yokuhambisa. I-AOOD SDI isangqa semisesane inikezela nje ngesitayile sokudibanisa kunye ukuya kuthi ga kumajelo angama-30 esignali yokhetho.
