Ithegi yesekethe evaliweyo (i-CCTV evaliweyo), ekwabizwa ngokuba yiHiction Viblance, isetyenziselwa ukuhambisa imiqondiso yevidiyo kubabekisi beevidiyo. Akukho mahluko okhethekileyo phakathi kokusebenza kwelensi yekhamera ye-quara kunye ne-CCTV yekhamera. I-CCTV I-Lensed yekhamera ye-CCTV ilungisiwe okanye itshintshisekile, kuxhomekeka kwinkcazo eyimfuneko, enjengokuthi gabhu, i-aperture, ijonga i-angle, ufakelo okanye ezinye izinto ezinjalo. Xa kuthelekiswa nelensi yekhamera yemveli enokuthi ilawule ukubonakaliswa ngesantya seShutter kunye ne-IRIS, i-CCT ye-CCTV inexesha lokuvelela ngokusebenzisa i-iris evulekileyo kuphela ngokuvula i-iris kuphela. Izinto ezimbini eziphambili ekufuneka ziqwalaselwe xa ukhetha i-lenseds ngumsebenzisi ocacisiweyo kunye nohlobo lokulawula i-IRIS. Iindlela ezahlukeneyo zokukhwela zisetyenziselwa ukunyusa ilensi ukuze zigcine ukuchaneka komgangatho wevidiyo.
Iikhamera ze-CCTV ezingakumbi zisetyenziselwa ukhuseleko kunye neenjongo zokuphononongwa, ezinempembelelo entle ekukhuleni kwentengiso ye-CCTV. Kule minyaka imbalwa idlulileyo, kuye kwakho unyango lwakutsha nje kwimfuno yeekhamera ze-CCTV njengeearhente ezigunyazisiweyo zokufaka iikhamera ze-CCTV kwiivenkile ze-CCTV kwiivenkile ezithengisayo kwaye ziphephe imisebenzi engekho mthethweni . Ngokwanda kweenkxalabo zokhuseleko malunga nokufakwa kweekhamera ze-Umakhishithi zesekethe ezivaliweyo kwizakhiwo, ufakelo lweekhamera zesekethe oluvaliweyo lweTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki leTeki. Nangona kunjalo, ukukhula kwentengiso ye-CCTV le-CCTV iphantsi kwezithintelo ezahlukeneyo, kubandakanya umda wemihlaba. Akunakwenzeka ukuchaza ubude obujolise kuzo kunye nokuvezwa njengekhamera yemveli. Ukuhanjiswa kweekhamera ze-CCTV kusetyenziswe ngokubanzi e-United States, iBritane, iChina, eJapan, eJapan, eJapan, eMzantsi Asia kunye nezinye iindawo zentengiso ye-CCTV.
