Kuyinto engenakuphikwa lokhoi-adaptha yepulaki yamandla ye-cctvibalulekile ekuphepheni kwevidiyo yakho namakhamera okuphepha.Ukuze uqinisekise ukuphepha kanye nobuqotho besistimu yakho yokugada isiqeshana sevidiyo, izifaki kanye nabasebenzisi kudingeka bakhethe ukunikezwa kwamandla okuhle kakhulu.Ukunikezwa kwamandla kwekhwalithi ephansi kungabangela ukuhlanekezela kwesithombe, ukucwayiza, nokulimala kwemishini yekhamera yokuvikela.Ngokuvamile, amakhamera okuphepha angaphandle asebenzisa i-adaptha yamandla engu-12v dc engu-2.1 mm 1a cctv, kanye namakhamera we-PTZ asebenzisa ugesi we-24V AC, amanye amakhamera okuphepha angase asebenzise amandla angu-220V AC, ugesi we-5V DC usetshenziswa kabanzi kumakhamera okuphepha angaphakathi.
Ama-adaptha kagesi noma amabhokisi omjikelezo?
Wonke amakhamera okuvikela adinga uhlobo oluthile lwamandla.Amabhokisi okujikeleza kwamandla futhi futhii-adaptha yamandla yekhamera ye-cctvasetshenziswa kuningi lokufakwa kwamakhamera okuvikela.Uma ufaka amakhamera angu-4 noma ngaphansi kakhulu, iningi labafaki ngokuqinisekile lizokhetha ukusebenzisa i-adaptha yamandla nesihlukanisi kuyilapho ukusetha kuhlanganisa amakhamera amaningi, bazosebenzisa ibhokisi lokusabalalisa amandla.Lapho ukhetha i-adaptha yamandla, qiniseka ukuthi uthola eyodwa esekela i-voltage kanye nezilinganiso ze-amperage zamakhamera akho.
Wonke amakhamera okuvikela adinga uhlobo oluthile lwamandla.Amabhokisi okuhambisa amandla kanye ne-adaptha yamandla yekhamera ye-cctv asetshenziswa ekufakweni okuningi kwamakhamera okuvikela.Uma ufaka amakhamera angu-4 noma ngaphansi kakhulu, iningi labafaki ngokuqinisekile lizokhetha ukusebenzisa i-adaptha yamandla nesihlukanisi kuyilapho ukusetha kuhlanganisa amakhamera amaningi, bazosebenzisa ibhokisi lokusabalalisa amandla.Lapho ukhetha i-adaptha yamandla, qiniseka ukuthi uthola eyodwa esekela i-voltage kanye nezilinganiso ze-amperage zamakhamera akho.
Ikhamera yokuphepha isekela kokubili i-DC12V/AC24V, ungayikhetha kanjani i-adaptha yamandla e-ac yekhamera ye-cctv?
I-adaptha yamandla
Amabhokisi okusakazwa kwe-CCTV
Ukukhetha ukunikezwa kwamandla kwe-AC24V, ngoba ebangeni lokudlulisela elifanayo, i-voltage enkulu, ukusetshenziswa okuncishisiwe.Amandla kagesi aphezulu angavumela ikhamera ye-elekthronikhi ukuthi ithole amandla anele.Ngaleso sikhathi, usebenzisa i-AC 24V, lapho ususa iphutha kumakhamera okuphepha, ungakhetha ukuvumelanisa amandla kagesi, lokhu kungavumelanisa imvamisa yokuma yesithombe kuwo wonke amadivayisi ahlukahlukene.
Indlela yokunikeza amandla anele kumakhamera okuphepha?
Lokhu kukhathazeka kulukhuni ukukuphendula kulabo bafaki abangenamakhono, abaningi babo bathola ukuthi umthamo wamandla awanele ngesitolimende sangempela, badinga ukukhuphula ukunikezwa kwamandla kagesi.Eqinisweni, ikhamera yezokuphepha ye-elekthronikhi idinga amandla amakhulu uma kuqala amabhuzu, kanye nokusetshenziswa kokudlulisela, ngenxa yaleso sizathu, ukunquma ukunikezwa kwamandla adingekayo, akusho ukuthi uvele wengeze amandla alinganiselwe ekhamera ngayinye ndawonye.Indlela efanele ihlanganisa amandla alinganiselwe, bese uphindaphinda u-1.3, umphumela uwukuphakela amandla kwangempela okudingekile kumakhamera okuphepha, ngaphezu kwalokho udinga ukucabangela ukusetshenziswa kwamandla ezintambo kanye nohlelo lwesabelomali samandla.
Isibonelo:
Uma sifaka amakhamera okuvikela angamayunithi angu-100 esakhiweni sebhizinisi, isilinganiso samandla samandla singu-4W sekhamera yokuvikela.Ungabala kanjani amandla adingekayo?
Ukusetshenziswa kwamandla ekhamera yokuphepha: 4W x 100 amadivayisi x 1.3 = 520W
Ngemva ukusetshenziswa, edingekayo amandla simo: 520W x 1.3 = 676W
Ukusetshenziswa kwentambo kanye nesabelomali samandla: 676W x 1.3 = 878W
Yini okudingeka ihlale icacile lapho usetha i-adaptha yekhamera ye-cctv?
Abasebenzisi kufanele bagweme ukusebenzisa umthombo wamandla omaphakathi noma owodwa.Isici njengoba sibhalwe ngezansi:
1) Uma uvula/uvala ukunikezwa kwamandla ukulungisa uhlelo lwekhamera.Wonke amakhamera okuvikela ayaqala nawo, ukubizwa kwe-boot current kukhulu, lokhu kuzoba nomthelela omuhle ekuhlinzekweni kwamandla kagesi, kungase kubangele ukulimala kwamandla.
2) Uma wonke amakhamera okuphepha esebenzisa ugesi ongawodwa.Uma ukunikezwa kwamandla kuba nenkinga, wonke amakhamera okuphepha kwevidiyo azocisha.Ikakhulukazi kwezinye izindawo zokungena ezibalulekile lapho ungeke ukwazi ukubeka iso.
Ngakho, iyiphi indlela efanele?Uma sithatha lesi sibonelo esingenhla, uhlaka lwezimboni olulodwa ludinga amakhamera okuphepha wezinhlelo eziyi-100, adinga ugesi ongu-800W ngokuphelele, uhlelo olufanele lusebenzisa izinsiza zikagesi zezinhlelo ezi-4, ugesi ngamunye unikeza amandla angama-200W.Ukuqinisekisa ukuthi, lapho ugesi owodwa uphuka, amanye amakhamera okuphepha nawokuvikela asasebenza.
Yiziphi ezinye izindaba okufanele zicatshangelwe?
1) Uma uxhuma amakhamera okuphepha kuukunikezwa kwamandla kagesi, unganamathiseli amakhamera okuvikela axhumene nezwe lonke kanye namakhamera okuphepha axhumene nebanga eliseduze endaweni efanayo yamandla.Uma ixhunywe kugesi ofanayo ncamashi, ngokushesha nje lapho amandla kagesi ebiza kakhulu, azolimaza eduze kwamakhamera okuvikela axhumene nebanga, ngokushesha nje lapho amandla ogesi encipha kakhulu, amakhamera anamathiselwe amabanga amade ngeke asebenze.Wonke amakhamera okuphepha axhumene nebanga eliseduze kufanele axhumeke kugesi owodwa, futhi wonke amakhamera okuphepha axhumene nebanga elide kufanele anamathisele kokunye ukunikezwa kwamandla.
2) Uma ububanzi bokufakwa kwamakhamera okuvikela bukude kakhulu, abasebenzisi bangasebenzisa amandla kagesi amakhulu, njenge-30V, 36V, 48V njll, futhi basebenziseUkunikezwa kwamandla kagesi we-220V AC.
