Kamera isa (CVBS, CCTV)

Mu rwego rwumutekano wo kugenzura amashusho, kugereranya na digitale, kimwe numuyoboro uherekejwe.Kamera yumutekano yambere irasa (Analog), ibyo bita analog, bivuze ko bigereranya ubwinshi bwumubiri bugereranya amajwi, amakuru yishusho, ikimenyetso cyurumuri cyintego ifotorwa gihinduka ikimenyetso cyamashanyarazi, imiterere yikigereranyo ikimenyetso kigereranya impinduka mumakuru.Umucyo utandukanye wikintu gifotorwa uhuye nagaciro keza keza, ikigezweho mumashanyarazi ya kamera ya kamera izahinduka.Ikimenyetso cya Analog ni ugukoresha iyi mpinduka muri iki gihe kugirango uhagararire cyangwa wigane ishusho yafashwe, wandike ibiranga optique, hanyuma binyuze muri modulation na demodulation, ikimenyetso kizoherezwa kubakira, cyerekanwe kuri ecran, gisubizwa mumashusho yumwimerere optique. .

Kamera zisanzwe zishobora kugabanywamo kamera ya SD igereranya na kamera ya HD ikurikije ibyemezo byabo.Kamera igereranya ikoresha BNC ihuza amashusho asohora amashusho.

Kamera ya CVBS

Kamera ya Analog SD izwi kandi nka kamera ya CVBS, ibyo bita CVBS bivuga Ikimenyetso cya Video Yerekana Ikimenyetso, ni ukuvuga ibimenyetso byerekana amashusho.Itanga amakuru muburyo bwa analog.Video igizwe na chromatic aberration (hue na saturation) hamwe na luminance (umucyo) kandi ikabihuza mumitsi igenda ishira, ikoherezwa hamwe nikimenyetso kimwe.

Kamera za CVBS zikoresha TVLine (umurongo wa tereviziyo, umurongo wa TV) gupima ubushobozi bwo gukemura amashusho.Kamera ya mbere ya CVBS igereranwa irashobora kugerwaho hifashishijwe monitor ya BNC igereranya yerekana amashusho, kandi ubukana bwishusho kuri iyi monitor ya analog mubyukuri ni urwego rurambuye rwumurongo wera utambitse.Kamera igereranya rero yibice byapimwe nayo yitwa TV Line, izwi kandi nka TV Line (ni ukuvuga TVLine), rimwe na rimwe nanone byitwa ko bisobanutse neza.Kamera ya Analog isanzwe igeragezwa na ISO12233 Ikarita Yimbonerahamwe (Imbonerahamwe), hamwe nubufasha bwibikoresho byabandi, nka ImaTest, HYRes, iSeetest nizindi software kugirango usome agaciro nyako.Kurugero, imirongo 650 bivuze ko iyi kamera ishobora gutandukanya kugeza kumurongo washyizwe kumurongo wikarita yikizamini hafi yagaciro ka 650.

Porogaramu ya kamera ya CVBS ni myinshi, intandaro ya buri gahunda ni DSP na sensor ibice bibiri.Gahunda ya DSP yambere cyane cyane SS-1 ya Sony (2163), SS-11 (3141/2), SS-11X (4103), SS-HQ1 (3172), SS-2, Effio-E (SS4), Effio-P, Effio-A, Effio-V, nibindi .. Panasonic kugeza D5 cyane cyane D4, D5 MN673276, Samsung ya Koreya, itunganya NEXTCHIP, serivise ya A-NOVA ADP yo muri Tayiwani, nibindi .. Kandi sesnor nayo cyane cyane kuri Sony, Panasonic, Samsung cyane cyane.DSP hamwe na sensor zitandukanye zavuzwe haruguru zirashobora gushushanywa kubisubizo bitandukanye bya kamera.

Urukurikirane rwa Effio ruhinduka Sony muburyo bwa analog SD yo kugenzura kamera ibihe byindirimbo yanyuma.“Effio” ni “Kuzamura Ibiranga hamwe no Gutunganya Amashusho meza” (Byongeweho Ibiranga na Firime Nziza).Igisubizo ntarengwa cyuruhererekane rwa Effio ni imirongo 750 - imirongo 800.Nibisubizo bihanitse byigeze kugerwaho na kamera ya analog.Kamera isanzwe ya Effio ifite pigiseli ikora neza ya 976 (horizontal) x 582 (vertical), bityo izwi kandi nka kamera 960H (pigiseli ikora neza irenze 960 muburyo bwa horizontal).

Urukurikirane rwa Effio rwashyizwe ahagaragara ahagana mu 2009, kandi igisubizo cya Effio-P cyatangijwe mu 2012. Nyuma yibyo Sony izibanda cyane cyane kubikorwa byubushakashatsi niterambere ryiterambere kuri CMOS, kamera ya SD nayo nayo irangira buhoro buhoro.

Kamera HD

Sony yataye CCD, intego nyamukuru izimurirwa muri CMOS ni ukubera ko imiterere imwe yo gukemura, igiciro cya CMOS kiri hasi cyane, kandi uko imyanzuro irenze, niko icyuho cyibiciro kinini, bivuze ko CCD idakwiriye gukemurwa cyane. kamera z'umutekano.Kamera z'umutekano kuri HD, ikintu cya mbere kigomba kuvaho ni sensor ya CCD.
