Ma adapter amphamvu kapena mabokosi ozungulira?
Makamera onse otetezera amafuna mtundu wina wa mphamvu.Mphamvu kufalitsidwa mabokosi komansocctv camera power adapteramagwiritsidwa ntchito pakuyika kwamakamera ambiri oteteza.Ngati muyika makamera 4 kapena kuchepera, oyika ambiri amasankha kugwiritsa ntchito adapter yamagetsi ndi zogawa pomwe zokhazikitsira zimakhala ndi makamera ambiri, amagwiritsa ntchito bokosi logawa mphamvu.Posankha adapter yamagetsi, onetsetsani kuti mwapeza yomwe imathandizira mphamvu yamagetsi komanso masanjidwe a makamera anu.

Kamera yachitetezo imathandizira onse DC12V/AC24V, momwe mungasankhire adaputala yamagetsi ya cctv kamera?
Adaputala yamagetsi
CCTV kufalitsidwa mabokosi
Kutenga magetsi a AC24V, chifukwa mumtundu womwewo wotumizira, voteji yayikulu, kuchepetsedwa kwa mowa.Magetsi okwera amatha kuloleza kamera yamagetsi kuti ipeze magetsi okwanira.Pakadali pano, pogwiritsa ntchito AC 24V, mukakonza makamera otetezera, mutha kusankha mphamvu yolunzanitsa, izi zitha kulunzanitsa mafupipafupi azithunzi pazida zosiyanasiyana.
Momwe mungaperekere mphamvu zokwanira makamera otetezera?
Nkhawa iyi ndiyovuta kuyankha kwa oyika opanda luso, ambiri aiwo amawona kuti mphamvu yamagetsi siyokwanira pang'onopang'ono, amayenera kuwonjezera magetsi owonjezera.M'malo mwake, kamera yamagetsi yachitetezo imafuna mphamvu yayikulu ikayamba nsapato zonse, kuphatikiza kugwiritsa ntchito kutumizira, chifukwa chake, kudziwa mphamvu zomwe zikufunika, sizikutanthauza kuti mumangowonjezera mphamvu zovoteledwa pamakamera aliwonse palimodzi.Njira yoyenera ndikuphatikiza mphamvu yovotera, kenako kuchulukitsa 1.3, zotsatira zake ndimagetsi ofunikira pamakamera otetezera, komanso muyenera kuganizira za kutengera mphamvu zamawaya komanso dongosolo la bajeti yamagetsi.
Chitsanzo:
Ngati tiyika makamera achitetezo a mayunitsi 100 mnyumba yamabizinesi, mphamvu yomwe ili pagulu ndi 4W ya kamera yoteteza.Momwe mungawerengere magetsi ofunikira?
Kugwiritsa ntchito mphamvu kwa kamera yachitetezo: 4W x 100 zipangizo x 1.3 = 520W
Pambuyo kumwa, chofunika mphamvu kusanja: 520W x 1.3 = 676W
Kugwiritsa ntchito chingwe komanso bajeti yamagetsi676W x 1.3 = 878W
Ndi chiyani chomwe chiyenera kupewedwa mukakhazikitsa adapter yamagetsi ya cctv kamera?
Ogwiritsa ntchito ayenera kupewa kugwiritsa ntchito gwero lapakati kapena limodzi.Zomwe zalembedwa pansipa:
1) Mukayatsa / kuzimitsa magetsi kuti mukonze makina a kamera.Makamera onse otetezera amayambanso, kuyitanidwa kwa boot current ndikwambiri, izi zitha kukhala ndi zotsatira zabwino pamagetsi, zitha kuwononga magetsi.
2) Ngati makamera onse otetezeka amagwiritsa ntchito magetsi okha.Mphamvu yamagetsi ikakumana ndi vuto, makamera onse oteteza makanema amazimitsa.Makamaka pazolowera zofunika kwambiri zomwe simungathe kuziyang'anira.
Ndiye njira yoyenera ndi iti?Potengera zomwe tafotokozazi, gawo limodzi la mafakitale likufuna makamera oteteza makina 100, omwe amafunikira mphamvu ya 800W, kukonza koyenera kumagwiritsa ntchito magetsi anayi, magetsi aliwonse amapereka mphamvu ya 200W.Kuonetsetsa kuti, mphamvu imodzi ikawonongeka, makamera ena onse otetezera ndi chitetezo akugwirabe ntchito.
Ndi zinthu zina ziti zomwe ziyenera kukumbukiridwa?
1) Mukalumikiza makamera otetezera kumagetsi, musaphatikize makamera otetezedwa olumikizidwa ndi dziko komanso makamera otetezedwa ndi chitetezo olumikizidwa ndi mtunda womwewo.Ngati chikugwirizana ndi magetsi omwewo, mphamvu yamagetsi ikakhala yokwera mtengo kwambiri, idzawononga makamera otetezedwa pafupi ndi osiyanasiyana, mwamsanga mphamvu yamagetsi ikachepetsedwa, makamera otalikirana sangagwire ntchito.Makamera onse otetezedwa oyandikana nawo ayenera kulumikizana ndi magetsi amodzi, ndipo makamera onse otetezedwa otalikirana akuyenera kulumikizidwa ndi magetsi ena.
2) Ngati kuyika kwa makamera odzitchinjiriza kuli kutali kwambiri, ogwiritsa ntchito atha kugwiritsa ntchito magetsi ochulukirapo, monga 30V, 36V, 48V etc.220V AC magetsi.
