Ngo-1942, oosonzululwazi baseJamani baba ngabokuqala ukuqulunqa nokusebenzisa umabonakude ovaliweyo (CCTV) ukujonga ukuqaliswa kwe-rocket ye-V2. Kungekudala emva koko, izazinzulu zaseMelika zabona amandla etekhnoloji kwaye zayisebenzisa ukujonga iimvavanyo zebhombu yeathomu. Ukuya phambili ngokukhawuleza kule mini, kwaye iCCTV iqhubele phambili ibe yeyona ndlela ikrelekrele, idumileyo, kunye neenkqubo zokhuseleko ezibandakanya zonke emhlabeni.
Isetyhula evaliweyo kwi-CCTV ichaza indlela ifidi yevidiyo ehanjiswa ngayo ngokuthe ngqo kwiqela elithile, elilinganiselweyo labahloli, ngokuchaseneyo nosasazo oluqhelekileyo, olusekelwe kumabonakude.
Kwaye nangona iinkqubo zeCCTV zixhaphake kakhulu kule mihla, abathengi kufuneka baqwalasele izinto ezininzi xa bekhetha ukuba loluphi uhlobo olulungele bona. Kweli nqaku, siza kucacisa yonke into ekufuneka uyazi malunga neCCTV kunye nokuba yintoni na amashishini ekufuneka ayithathele ingqalelo phambi kokuba agcine isitokhwe.

Iindidi ezi-2 eziphambili zeekhamera zeCCTV: i-analog vs. IP
Iikhamera zokhuseleko zeCCTV zinenjongo enye: ukurekhoda ividiyo yokhuseleko lwabucala, kwaye ke ngoko zixhaphakile kwiindawo apho abanini bafuna ukukhusela impahla yabo, njengeeofisi, izakhiwo, imizi-mveliso, okanye iindawo zokugcina iimpahla.
Ezi khamera ziwela kwiindidi ezimbini:
Iikhamera zeCCTV zeAnalog
Ngaphandle kwenkqubela phambili yetekhnoloji yamva nje kwitekhnoloji yeCCTV, i-analog Iikhamera zeCCTV hlala lolona hlobo luxhaphakileyo olusetyenziswayo namhlanje. Ezi nkqubo zeCCTV zibonelela ngeempawu ezisisiseko kwaye zigcina zonke iividiyo ezirekhodiweyo ekuhlaleni kwisiza.
IP CCTV iikhamera
Ngeli xesha, iikhamera ze-IP ziza neempawu eziphambili ngakumbi kunye nokubonelela zonke iimpawu ezisisiseko zabalingane babo be-analog. Babonisa izisombululo eziphezulu, ukusondeza kude, ukulungiswa kwekhamera, kunye nokujonga kude ngePC okanye i-smartphone. Ukongeza, ezi khamera zinokulumkisa abasebenzisi ukuba babone umsebenzi ongaqhelekanga.
3 iikhamera zeCCTV ezidumileyo ongakhetha kuzo
Iikhamera zeCCTV zifumaneka ngezitayile ezahlukeneyo, nganye iyilelwe iimfuno ezahlukeneyo zokucupha. Ukusuka kwidome ukuya kwibhulethi kunye neekhamera zemini nobusuku, isitayile ngasinye sibonelela ngeenzuzo ezahlukeneyo. Masijonge ngakumbi:
1. Iikhamera zeCCTV zeDome
Iikhamera zeCCTV zeDome fumana igama layo kwi-casing yayo emile okwedome, nto leyo eyinika inkangeleko ethambileyo neyingqondi. Nangona uyilwe ngendlela echuliweyo, le milo iyasebenza kakhulu ekuthinteleni izaphuli-mthetho. Njani? Idome ifihla indlela ikhamera ejonge ngakuyo, idala ukungaqiniseki kumasela anokubakho okanye abonakalisi ngelixa ikwaphucula ukhuseleko lwee-angle ezininzi.
Izibonelelo eziphambili
- Uyilo lwayo oluyingqondi ludibanisa ngokungenamthungo kuyo nayiphi na imeko
- Iikhamera zeCCTV zeDome ziguquguquka ngokwaneleyo ukuba zisetyenziswe ngaphakathi nangaphandle
- I-dome casing yenza ukuba ikhamera ilumke kwaye iyikhusele ekubhubhiseni nasekonakalisweni
- Nikeza i-inshorensi epheleleyo kunye nokujikeleza kwe-360-degree ukuqinisekisa uhlolo olupheleleyo
2. Bullet CCTV cameras
Bullet CCTV cameras kananjalo bafumana igama labo kwimbumbulu-ezifana cylindrical uyilo. Ezi khamera zigqwesa ekubekeni iliso kumgama omde kwaye zixhaphake kakhulu ukuba zisetyenziswe ngaphandle, ngokuyinxenye ngenxa yokugquma kwazo kwimozulu (ziyakwazi ukumelana nokukhanya kwelanga, imvula, ukungcola nothuli). Ziyakwazi ukunyuswa kwiindonga okanye iisilingi ukugxila kwiindawo ezithile.
Izibonelelo eziphambili
- Uyilo lwale khamera lubonakala kakhulu, lunika ithuba eliphezulu lokugxotha abo basenokuba ngabaphuli-mthetho
- Iikhamera zeCCTV zeBullet zomelele ngokwaneleyo ukuba zingamelana nobumdaka kunye neemeko ezirhabaxa zokusingqongileyo
- Ukugubungela kwabo umgama omde kubenza balungele ukujonga iindawo ezinkulu
- I-cylindrical casing ikhusela imvula, i-glare, kunye nothuli, iqinisekisa ukusebenza okuthembekileyo
3. Iikhamera zeCCTV zemini nobusuku
Ezi khamera babe noyilo olubonelela ngokusebenza okuthembekileyo kuzo zonke iimeko zokukhanyisa ngenxa yeechips zabo zokucinga ezinobuthathaka kakhulu, ezibavumela ukuba babambe ividiyo ecacileyo kungakhathaliseki ixesha lemini. Ngale ndlela, baqinisekisa umgangatho womfanekiso ongaguqukiyo kwiindawo ezahlukeneyo zokukhanya.
Izibonelelo eziphambili
- Inokuhambisa ushicilelo olucacileyo nakwisetingi ezimnyama
- Iyakwazi ukuthwebula imifanekiso ngombala kunye neendlela ezimnyama namhlophe
- Unokuphatha ngokulula ilitha, ukukhanya, ukukhanya kwelanga, kunye nokukhanya okuphantsi
- Yiba necasing eqinileyo ekhusela ikhamera kwizinto ezirhabaxa, izenza zilungele ukusetyenziswa ngaphandle
Ngawaphi amashishini ekufuneka eqwalasele xa ekhetha iinkqubo zeCCTV
1. Iintambo kunye noqhagamshelwano
Into yokuqala abathengi abanokuthi bayiqwalasele xa kuthengwa a Inkqubo yeCCTV kukuba bafuna ukuseta ucingo okanye olungenazingcingo. Iinkqubo zeCCTV ezinocingo zibonelela ngoqhagamshelwano oluzinzile ngakumbi, njengoko iintambo zevidiyo zithumela idatha ngokuthe ngqo kwirekhoda yevidiyo yedijithali. Nangona kunjalo, ukufakela ezi ntambo kunokuba yingxaki, ngakumbi ukuba abathengi bafuna ukufaka iikhamera kwiindawo ekunzima ukufikelela kuzo.
Ngakolunye uhlangothi, iinkqubo ezingenazintambo zithembele kwi-WiFi ukuthumela idatha yomfanekiso, evumela ukubekwa kweekhamera eziguquguqukayo. Nangona kunjalo, banokuba buthathaka xa kuziwa ekuphazamisekeni kwaye banokuphelelwa ngumsebenzi ukuba babekwe kude kakhulu kummkeli.
2. Ngaphakathi vs. ngaphandle
Abathengi nabo baya kukhetha iimodeli ngokuxhomekeke kwindawo abafuna ukuyibeka kuyo Iikhamera zeCCTV. Ngokufanelekileyo, kufuneka ubanike iinkqubo ezinokusebenza ngaphakathi nangaphandle, kodwa banokufuna iinkqubo ezikhethekileyo zokusetyenziswa kwe-niche ngakumbi.
Ubuncinci obuncinci kukuba iikhamera zevidiyo zangaphandle kufuneka zikhuseleke kwimozulu ukunqanda umonakalo kwizinto. Iikhamera zokhuseleko lwangaphandle kufuneka zibe noyilo olungagungqiyo ukuthintela abangeneleli ekuzameni ukuzaphula. Okokugqibela, iinketho zesitokhwe ezinombono wobusuku be-infrared (ukuya kuthi ga kwi-100 yeenyawo ezicetyiswayo) kwimifanekiso yokubona ebusuku.
