MuIP kamera system uye 100Mbps network cabling system, isu tinowanzo shandisa Cat5e network tambo yekutumira chiratidzo uye magetsi.Elzoneta ichatsanangura imwe ruzivo rwekutanga kwauri sepazasi:
Maitiro ekushandisa PoE magetsi ekupa?
Zvekupa magetsi, isu tinofanirwa kuve nepfungwa yePoE kutanga.PoE (Simba pamusoro peEthernet), zvinoreva kuti simba remagetsi rinobuda kubva kuPoE chinja kuenda kuIP-based terminals (senge IP phone, wlan access point uye IP kamera) kuburikidza neCat5e network cable.Ehe, zvese switch uye IP-based terminals dzakavaka-muPoE module;Kana IP-based terminals isina PoE module, inoda kushandisa Standard PoE splitter.
Kazhinji, tinosarudza kushandisa international standard PoE switch, inotsigira 48V-52V, inotevera IEEE802.3af/802.3at.Nekuti iyi PoE switch ine PoE smart yekuona basa.Kana tikashandisa isiri-standard PoE switch, 12V kana 24V, isina PoE smart detect function, kana yakabuda simba remagetsi kune IP-based terminals zvakananga pasinei nokuti vakagadzira-muPoE module kana kwete, zviri nyore kupisa IP-based terminals ports. , kunyange kukuvadza simba ravo module.
Iko kureba kwechiratidzo chekufambisa kuri kure?
Kutapurirana kureba kwetambo yetiweki kunoenderana nezvinhu zvetambo.Kazhinji, inoda kushandisa mhangura isina oxygen, nekuti kushorwa kwemhangura isina okisijeni idiki, mukati me30 ohms ye300 metres, uye saizi yemhangura yemhangura inowanzoita 0.45-0.51mm.Mune izwi, iyo yakakura yemhangura yepakati saizi, iyo idiki yekupikisa, iyo inoenderera mberi kureba kwekufambisa kuri.
Zvinoenderana neiyo Ethernet standard, iyo max chiratidzo chekufambisa chinhambwe nePoE switch i100 metres, zvinoreva kuti POE switch inoshandisa tambo dzepasirese network tambo dzemagetsi dzinogumira mumamita zana zvakare.Kupfuura 100 metres, data inogona kunonoka uye kurasikirwa.Kuti tive nechokwadi chemhando yeprojekti, isu tinowanzo tora 80-90 metres yecabling.
Dzimwe shanduko dzePOE dzepamusoro-soro dzinoti dzinokwanisa kufambisa masaini kusvika ku250 metres mu100Mbps network, ichokwadi here?
Hongu, asi kufambisa kwemasaini kunoderedzwa kubva ku100Mbps kusvika ku10Mbps (bandwidth), uye ipapo chiratidzo chekufambisa chinhambwe chinogona kuwedzerwa kusvika kuMax 250 metres (tambo ine okisijeni-isina mhangura yepakati).Iyi tekinoroji haigone kupa yakakwira bandwidth;Pane zvinopesana, bandwidth inomanikidzwa kubva ku100Mbps kusvika ku10Mbps, uye iyo isina kunaka kune yakatsetseka yakakwirira-tsanangudzo yekufambisa yekutarisa mifananidzo.10Mbps zvinoreva chete zvidimbu zviviri kana zvitatu zve4MP IP kamera zvinogona kuwanikwa kune iyi Cat5e tambo, yega yega 4MP IP kamera's bandwidth ndeye Max 2-3Mbps muDynamic scene.Mushoko, Cat5e network tambo haina kupfuura 100 metres mucabling.
ELZONETA Cat5e network tambo inoshandisa yakakwirira yakachena-isina core ine 0.47mm yemhangura yepakati dhayamita, kuti ienderane nePoE IP kamera uye yepamusoro-yemhando yepamusoro PoE switch.Zvakadai izvi zvinovimbisa kutapurirana kwechiratidzo uye kugadzikana kwemagetsi kune iyo yese CCTV yekutarisa system.
