Mu makina a kamera a IP, Kusintha kumalumikizidwa ndi kamera ya IP kuti ipeze magetsi m'njira zinayi izi:
Kusintha kwa PoE kokhazikika kumalumikizidwa ndi kamera ya PoE
Kusintha kokhazikika kwa PoE kumalumikizidwa ndi kamera ya Non-PoE
Kusintha kwa Non-PoE kumalumikizidwa ndi kamera ya PoE
Kusintha kwa Non-PoE kumalumikizidwa ndi kamera ya Non-PoE

A.Kusintha kwa PoE kokhazikika kumalumikizidwa ndi PoE kamera
Iyi ndi njira yophweka mwa njira zinayi.Mutha kulumikiza mwachindunji a
netiweki ku kamera ya netiweki yomwe imathandizira mphamvu ya POE kuchokera ku Standard PoE switch.
Samalani mfundo zotsatirazi:
(1) Onani ngati chosinthira cha POE ndi kamera ya IP ndi zida zodziwika bwino za POE.
(2) Musanayambe kulumikiza chingwe cha netiweki, ndikofunikira kwambiri kuyang'ana mtundu wa chingwe cha netiweki ndikutsimikizira zomwe zili.Ngati khalidwe la chingwe cha netiweki ndi losayenerera kapena zofotokozera (IEEE 802.3af/802.3at standard) ndizosagwirizana, IP Camera singathe kupeza mphamvu kuchokera ku PoE yokhazikika.
 
B.Kusintha kwa PoE kokhazikika kumalumikizidwa ndi Non-PoE kamera
Mwanjira iyi, chosinthira cha POE chokhazikika chimalumikizidwa ndi kamera yomwe si-PoE ndi cholekanitsa cha POE.Pogwiritsa ntchito ntchito ya wolekanitsa wa POE, mphamvu imagawidwa mu zizindikiro za deta ndi zizindikiro za mphamvu.Mphamvu yotulutsa mphamvu ndi 5V, 9/12V, ndipo imafanana ndi kamera yopanda POE yokhala ndi zolowetsa za DC ndipo imathandizira IEEE 802.3af/802.3at muyezo.
 
C.Kusintha kwa Non-PoE kulumikizidwa ndi PoE kamera
Mwanjira iyi, chosinthiracho chimalumikizidwa mwachindunji ndi adaputala ya PoE poyamba.Kenako, adapter imalowetsa chizindikiro champhamvu ndi chizindikiro cha data ku
Kamera ya PoE yopangidwa ndi chingwe cha Ethernet.
Adaputala onse a PoE ndi kamera ya PoE amatsata IEEE 802.3af/802.3at muyezo.Njirayi imagwiritsidwa ntchito makamaka kukulitsa dongosolo la maukonde ndipo silingakhudze dongosolo loyambirira lamaneti.
 
D.Kusintha kwa Non-PoE kumalumikizidwa ndi Non-PoE kamera
Mwanjira iyi, pali njira ziwiri zomwe zili pansipa:
Kusintha kwa Non-PoE kumalumikizidwa mwachindunji ndi adaputala ya POE, kenako adaputala imalumikizidwa ndi kamera ya Non-PoE ndi cholekanitsa cha PoE popereka mphamvu ndi ma data.
Yankho lina ndikupereka mphamvu zodziyimira pawokha mwachindunji ndi chingwe chamagetsi, kenako ingogwiritsani ntchito chingwe cha Efaneti pongotumiza ma siginecha kuchokera ku Non-PoE kupita ku Non-PoE kamera.
 
Monga katswiri wothandizira makina owunikira a CCTV, Elzoneta amapanga mndandanda wonse wa Standard PoE switch ndi kamera ya PoE, ndipo zogulitsa zimatsata IEEE 802.3af/802.3at muyezo.Pa dongosolo latsopano la polojekiti ya CCTV, Elzoneta akuwonetsa kuti atenge njira yoyamba yolumikizira yosinthira PoE ndi kamera ya PoE IP.Njira yotereyi ndiyosavuta kuyika ndi kukonza, imachepetsanso kulephera kwa mphamvu ndi kufalitsa chizindikiro cha kanema, ndikuwonetsetsa kuti dongosolo loyang'anira makanema likhale lokhazikika.
