Ayinakuphikiswa loo ntoiadaptha yeplagi yamandla yecctvibaluleke kakhulu kukhuseleko lwakho lwevidiyo kunye neekhamera zokhuseleko.Ukuqinisekisa ukhuseleko kunye nemfezeko yenkqubo yakho yokujonga ividiyo yekliphu, abafakeli kunye nabasebenzisi kufuneka bakhethe unikezelo lwamandla olusemgangathweni.Unikezelo lwamandla olukumgangatho ophantsi lunokubangela ukuphazamiseka komfanekiso, ukushukuma, kunye nomonakalo wezixhobo zekhamera yokukhusela.Ngokwesiqhelo, iikhamera zokhuseleko lwangaphandle zisebenzisa i-12v dc i-adaptha yamandla i-2.1 mm 1a cctv, kunye neekhamera ze-PTZ zisebenzisa umbane we-24V AC, ezinye iikhamera zokhuseleko zinokusebenzisa amandla e-220V AC, umbane we-5V DC usetyenziswa ngokubanzi kwiikhamera zokhuseleko lwangaphakathi.
Iiadaptha zamandla okanye iibhokisi zokujikeleza?
Zonke iikhamera zokhuseleko zifuna uhlobo oluthile lomthombo wamandla.Iibhokisi zokujikeleza kwamandla kwaye kwakhonaiadaptha yamandla yekhamera yecctvzisetyenziswa kuninzi lofakelo lweekhamera zokhuseleko.Ukuba ufaka iikhamera ezi-4 okanye ngaphantsi, uninzi lwabafakeli ngokuqinisekileyo baya kukhetha ukusebenzisa iadaptha yamandla kunye ne-splitter ngelixa ukusetha kubandakanya iikhamera ezininzi, baya kusebenzisa ibhokisi yokuhambisa amandla.Xa ukhetha iadaptha yamandla, qiniseka ukuba ufumana enye exhasa i-voltage kunye ne-amperage rankings kwiikhamera zakho.

Ikhamera yokhuseleko ixhasa zombini i-DC12V/AC24V, ungayikhetha njani iadaptha yamandla ye-ac yekhamera ye-cctv?
Iadaptha yamandla
Iibhokisi zokujikeleza zeCCTV
Ukukhetha umbane we-AC24V, kuba kuluhlu olufanayo lokuhambisa, amandla ombane amakhulu, ukunciphisa ukusetyenziswa.Amandla ombane aphezulu anokuvumela ikhamera yombane ukuba ifumane umbane owaneleyo.Ngeli xesha, usebenzisa i-AC 24V, xa ucoca iikhamera zokhuseleko, unokukhetha unikezelo lwamandla olungelelwaniso, oku kunokuvumelanisa ifreyimu ethe nkqo yefoto kuzo zonke izixhobo ezahlukeneyo.
Indlela yokubonelela ngamandla aneleyo kwiikhamera zokhuseleko?
Le nkxalabo inzima ukuyiphendula kwabo bafakeli bangaqeqeshelwanga, uninzi lwabo lufumanisa ukuba umthamo wamandla awonelanga kwizavenge zokwenyani, kufuneka bonyuse ubonelelo lwamandla olongezelelweyo.Ngapha koko, ikhamera yezokhuseleko ye-elektroniki ifuna into enkulu yangoku xa iqala kuzo zonke iibhutsi, kunye nokusetyenziswa kokuhanjiswa, ngenxa yeso sizathu, ukumisela umbane ofunekayo, akuthethi ukuba wongeza amandla alinganisiweyo ekhamera nganye kunye.Ubuchule obufanelekileyo bubandakanya amandla alinganisiweyo, emva koko uphindaphinde i-1.3, isiphumo kubonelelo lwamandla lokwenyani oluyimfuneko kwiikhamera zokhuseleko, ngaphezu koko kufuneka uthathele ingqalelo ukungena kombane kunye nesicwangciso sohlahlo lwabiwo-mali lwamandla.
Umzekelo:
Ukuba sifaka iiyunithi ze-100 zeekhamera zokhuseleko kwisakhiwo seshishini, ukuthathwa kwamandla okubekwe kwi-4W yekhamera yokukhusela.Indlela yokubala unikezelo lombane olufunekayo?
Ukusetyenziswa kwamandla ekhamera yokhuseleko: 4W x 100 izixhobo x 1.3 = 520W
Emva kokusetyenziswa, umgangatho wamandla ofunekayo: 520W x 1.3 = 676W
Ukusetyenziswa kwentambo kunye nohlahlo lwabiwo-mali lwamandla: 676W x 1.3 = 878W
Yintoni ekufuneka igcinwe icacile xa kumiselwa i-adaptha yombane yekhamera ye-cctv?
Abasebenzisi kufuneka bakuphephe ukusebenzisa umthombo ophakathi okanye omnye wobonelelo lwamandla.Umba njengoko udweliswe ngezantsi:
1) Xa uvula/ucima unikezelo lwamandla ukulungisa inkqubo yekhamera.Zonke iikhamera zokhuseleko ziqala nazo, ukubizwa kwe-boot yangoku inkulu, oku kuya kuba neempembelelo ezintle kubonelelo lwamandla, kunokubangela ukonakala kombane.
2) Ukuba zonke iikhamera zokhuseleko zisebenzisa umbane wodwa.Nje ukuba unikezelo lwamandla lube nengxaki, zonke iikhamera zokhuseleko zevidiyo ziya kucima ngokuqinisekileyo.Ngokukodwa kwezinye iindawo ezibalulekileyo zokungena apho ungenakho ukujonga.
Ke, yeyiphi indlela efanelekileyo?Ukuthatha umzekelo ongasentla, isakhiwo semizi-mveliso sibiza iikhamera ze-100 zokhuseleko, zifuna ngokupheleleyo umbane we-800W, ilungiselelo elichanekileyo lisebenzisa izixhobo ezi-4 zombane, umbane ngamnye unika amandla angama-200W.Ukuqinisekisa ukuba, xa umbane omnye uqhekeka, ezinye iikhamera zokhuseleko kunye nokhuseleko zisasebenza.
Yeyiphi eminye imiba efanele ukuqwalaselwa?
1) Xa uqhagamshela iikhamera zokhuselekoukunikezwa Amandla, musa ukuncamathisela iikhamera zokhuseleko eziqhagamshelweyo kunye nomgama okufuphi onxibelelene neekhamera zokhuseleko kunye nokhuseleko kunikezelo lwamandla olufanayo.Ukuba iqhagamshelwe kubonelelo lwamandla oluchanekileyo, kamsinya nje ukuba amandla ombane aduru kakhulu, ngokuqinisekileyo aya konakalisa kufutshane noluhlu lweekhamera zokhuseleko eziqhagamshelwe, kamsinya nje ukuba amandla ombane ancitshiswe, iikhamera ezincanyathiselwe umgama omde aziyi kusebenza.Lonke uluhlu olusondeleyo lweekhamera zokhuseleko ezinxibeleleneyo kufuneka ziqhagamshele kubonelelo lwamandla omnye, kwaye zonke iikhamera zokhuseleko lomgama omde kufuneka zincamathele komnye umbane.
2) Ukuba uluhlu lofakelo lweekhamera zokhuselo lukude kakhulu, abasebenzisi banokusebenzisa amandla ombane amakhulu, anje nge30V, 36V, 48V njl.220V AC unikezelo lwamandla.
