Kamar yadda muka sani, a cikin tsarin CCTV, kyamarar IP ita ce mafi mahimmancin na'urar gaba, musamman AI kamara, kyamarar PTZ.Ko wane irin kyamarar IP, dome/harsashi/PTZ, har ma da kyamarar gida mai kaifin baki, yakamata mu sami cikakken ra'ayi na abubuwan da suke ciki.Elzoneta zai bayyana muku amsar a cikin wannan labarin kamar yadda ke ƙasa.
1. Abun da ke ciki nasa idokamara:
Ya ƙunshi manyan sassa huɗu da ƙananan sassa uku.
Manyan sassa hudu: guntu kamara, ruwan tabarau, panel fitila, gidaje.
Ƙananan sassa uku: kebul na wutsiya, dutsen ruwan tabarau, ginshiƙin jan karfe, da dai sauransu.
Me yasa kyamarori daban-daban ke da pixel iri ɗaya, amma farashin daban?Babban batu shine ingancin kayan masarufi da maganin software da ake amfani da su a waɗannan sassa.
2. KamaraChip:
Babban muhimmin sashi na kyamarar cibiyar sadarwa shine guntu, kwakwalwar kyamara.An saka guntu a cikin motherboard;muhimman sassa guda biyu na motherboard su ne na’urar firikwensin hoto: CCD ko CMOS, da kuma na’urar sarrafa kwamfuta.
Anan, yakamata mu koyi wani bambanci tsakanin CCD da CMOS.
Don tsarin samarwa, CMOS ya fi CCD sauƙi.
Don farashi, CMOS ya fi CCD rahusa.
Don cin wuta, CMOS ke cinyewa bai kai CCD ƙarfi ba.
Don amo, CMOS yana da amo fiye da CCD.
Don kula da haske, CMOS ba shi da hankali fiye da CCD.
Don ƙuduri, CMOS yana da ƙaramin ƙuduri fiye da CCD.
Ko da yake CCD ta fi CMOS girma a ingancin hoto, CMOS yana da fa'idar ƙarancin farashi, ƙarancin wutar lantarki da ingantaccen wadata, ya zama abin da masana'antun na'urar CCTV suka fi so.Sabili da haka, fasahar masana'anta na CMOS ana haɓaka koyaushe kuma ana sabunta su, wanda ke sa bambanci kaɗan kaɗan.
3. Ruwan tabarau nasaka idanukamara
Mabuɗin ilimin game da Len na kyamara shine tsayin hankali da buɗe ido.
Tsawon hankali: Wannan shine adadin milimita na ruwan tabarau da muke yawan amfani da su.Gabaɗaya 4mm, 6mm, 8mm, 12mm da sauransu.
Mafi girman adadin millimeters, ƙaramin kewayon da nisa nesa da ruwan tabarau zai kama.Alal misali, don saka idanu kan bita da ɗakin ajiya, yawanci yana amfani da ruwan tabarau na 4 mm;zuwa babban ƙofar ginin mazaunin, yawanci yana amfani da 6 mm;zuwa bango da hanya, yawanci yana amfani da 12 mm.Tabbas, ya kamata a zaɓi ruwan tabarau a hankali bisa ga takamaiman aikace-aikacen.
Aperture: Yana da lambar F akan ruwan tabarau, yawanci F1.0, F1.2, F1.4, F1.6.
Karamin F-lambar buɗaɗɗen buɗaɗɗen shine, ƙarin haske mai haske, kuma mafi tsadar ruwan tabarau.
4. Hasken kyamarapanel
Fitilar hasken kamara na gama gari sun haɗa da: Tsare-tsare Hasken IR, hasken IR na yau da kullun, Fari/Haske mai dumi.
Manufar kwamitin hasken shine don samar da haske mai taimako ga ruwan tabarau da dare.Don hasken IR, wannan ruwan tabarau zai iya ganewa kuma ya kama hasken infrared kuma ya juya shi zuwa hoto.Fari/Haske mai dumi yawanci ana haɗe shi tare da babban hasken tauraro da ƙirar hasken baƙar fata, yana taimakawa kama hangen nesa da dare.
5. Gidajen kyamara
Gidajen kamara ya zo cikin siffofi daban-daban, ƙirar harsashi gabaɗaya, dome, mai sassauƙa.Abubuwan gidaje sune aluminum da filastik yawanci, waɗanda ke zuwa IP66/IP67 mai hana ruwa.
Wannan shine game da duk abin da kuke buƙatar sani game da gabaɗayan tsarin kamara.Kyamarar IP ta ELZONETA tana amfani da kwakwalwan kwamfuta masu inganci da na'urorin haɗi, ɗauki debugging kowane ruwan tabarau da daidaitattun launi, kuma yin sa'o'i 24 na gano tsufa.Abin da ya sa kyamarar Elzoneta na iya ci gaba da yin aiki mai kyau bayan shekaru 4-5 ta amfani da al'ada.
