Kuhlelo lwekhamera ye-IP, Ukushintsha kuxhumeke kukhamera ye-IP ukuze kunikezwe amandla ngezindlela ezine ezilandelayo:
Iswishi ye-PoE evamile ixhunywe kukhamera ye-PoE
Iswishi ye-PoE evamile ixhunywe kukhamera ye-Non-PoE
Iswishi ye-Non-PoE ixhunywe kukhamera ye-PoE
Iswishi ye-Non-PoE ixhunywe kukhamera ye-Non-PoE
A.Iswishi ye-PoE evamile ixhunywe ku-PoE ikhamera
Lena yindlela elula kwezine.Ungakwazi ukuxhuma ngokuqondile a
ikhebula lenethiwekhi kukhamera yenethiwekhi esekela amandla e-POE asuka ku-Standard PoE switch.
Naka amaphuzu alandelayo:
(1) Hlola ukuthi iswishi ye-POE nekhamera ye-IP kungamadivayisi ajwayelekile e-POE.
(2) Ngaphambi kokuxhuma ikhebula lenethiwekhi, kubaluleke kakhulu ukuhlola ikhwalithi yekhebula lenethiwekhi futhi uqinisekise imininingwane.Uma ikhwalithi yekhebuli yenethiwekhi ingafaneleki noma imininingwane (IEEE 802.3af/802.3at standard) ingqubuzana, Ikhamera ye-IP ayikwazi ukuthola amandla kusuka kuswishi ye-PoE evamile.
B.Iswishi ye-PoE evamile ixhunywe ku-Non-PoE ikhamera
Ngale ndlela, ukushintshwa kwe-POE okujwayelekile kuxhunywe kukhamera engeyona ye-PoE ngesihlukanisi se-POE esijwayelekile.Kusetshenziswa umsebenzi wesihlukanisi se-POE esijwayelekile, amandla ahlukaniswa abe amasiginali wedatha nezimpawu zamandla.Izinga lokuphuma kwamandla ngu-5V, 9/12V, futhi lifanisa ikhamera engeyona ye-POE nokokufaka kwe-DC futhi isekela i-IEEE 802.3af/802.3at evamile.
C.Iswishi ye-Non-PoE ixhunywe ku-PoE ikhamera
Ngale ndlela, ukushintshwa kuxhunywe ngokuqondile ku-adaptha ye-PoE kuqala.Bese, i-adaptha ifaka isignali yamandla kanye nesignali yedatha ku-
Ikhamera ye-PoE ngentambo ye-Ethernet.
Kokubili i-adaptha ye-PoE nekhamera ye-PoE ilandela i-IEEE 802.3af/802.3at evamile.Le ndlela isetshenziswa kakhulu ukwandisa isistimu yenethiwekhi futhi ngeke ithinte isistimu yenethiwekhi yasekuqaleni.
D.Iswishi ye-Non-PoE ixhunywe ku-Non-PoE ikhamera
Ngale ndlela, kunezixazululo ezimbili ezingezansi:
Iswishi ye-Non-PoE ixhunywe ngokuqondile ku-adaptha ye-POE, bese i-adaptha ixhunywa kukhamera ye-Non-PoE yisihlukanisi se-PoE ukuze kudluliselwe amandla nesignali yedatha.
Esinye isixazululo ukuhlinzeka ngamandla azimele ngokuqondile ngekhebula lamandla, bese usebenzisa ikhebula le-Ethernet ukuze nje udlulise isignali yedatha isuka ekushintsheni kwe-Non-PoE iye kukhamera ye-Non-PoE.
Njengomphakeli ochwepheshile wesistimu yokugada ye-CCTV, i-Elzoneta yenza uchungechunge olugcwele lwe-Standard PoE switch kanye nekhamera ye-PoE, futhi imikhiqizo ilandela i-IEEE 802.3af/802.3at standard.Ngohlelo olusha lwephrojekthi ye-CCTV, i-Elzoneta iphakamisa ukuthatha indlela yokuqala yokuxhumana yokushintsha kwe-PoE evamile kanye nekhamera ye-PoE IP.Le ndlela kulula ukufakwa nokugcinwa kwayo, iphinde yehlise izinga lokuhluleka kwamandla nokudluliswa kwesignali yevidiyo, futhi iqinisekise uhlelo lokubhekwa kwevidiyo oluzinze kakhudlwana.
