To znamen\u00e1, \u017ee u n\u011bkter\u00fdch za\u0159\u00edzen\u00ed nepot\u0159ebujete samostatn\u00e9 s\u00ed\u0165ov\u00e9 p\u0159ipojen\u00ed a samostatn\u00fd p\u0159\u00edvod nap\u00e1jen\u00ed. Pokud za\u0159\u00edzen\u00ed podporuje PoE, m\u016f\u017ee pro komunikaci i nap\u00e1jen\u00ed sta\u010dit jeden kabel.<\/p>\n

Jak to vypad\u00e1 v syst\u00e9mu IP interkom\u016f<\/h2>\n

V syst\u00e9mech IP interkom\u016f se PoE \u010dasto pou\u017e\u00edv\u00e1 pro vstupn\u00ed panely, vnit\u0159n\u00ed monitory a dal\u0161\u00ed s\u00ed\u0165ov\u00e1 za\u0159\u00edzen\u00ed. Kabel vede z PoE switche nebo jin\u00e9ho vhodn\u00e9ho zdroje nap\u00e1jen\u00ed k za\u0159\u00edzen\u00ed a tato jedin\u00e1 linka p\u0159en\u00e1\u0161\u00ed data i elekt\u0159inu.<\/p>\n

V praxi to \u010din\u00ed sch\u00e9ma zapojen\u00ed jednodu\u0161\u0161\u00edm a p\u0159ehledn\u011bj\u0161\u00edm. Nam\u00edsto dvou samostatn\u00fdch veden\u00ed m\u00e1te jedno.<\/p>\n

Pro\u010d je to u\u017eite\u010dn\u00e9<\/h2>\n

Hlavn\u00ed v\u00fdhodou PoE je, \u017ee sni\u017euje po\u010det kabel\u016f a zp\u0159ehled\u0148uje logiku instalace. To se st\u00e1v\u00e1 obzvl\u00e1\u0161t\u011b patrn\u00fdm tam, kde syst\u00e9m zahrnuje n\u011bkolik za\u0159\u00edzen\u00ed a nen\u00ed d\u016fvod mno\u017eit nap\u00e1jec\u00ed zdroje a dal\u0161\u00ed kabelov\u00e9 trasy.<\/p>\n

PoE tak\u00e9 usnad\u0148uje \u017eivot instalat\u00e9r\u016fm: m\u00e9n\u011b nap\u00e1jec\u00edch bod\u016f, m\u00e9n\u011b samostatn\u00fdch adapt\u00e9r\u016f a m\u00e9n\u011b m\u00edst, kde m\u016f\u017ee b\u00fdt n\u011bco zapojeno nespr\u00e1vn\u011b nebo ne\u00fahledn\u011b.<\/p>\n

Dal\u0161\u00edm praktick\u00fdm p\u0159\u00ednosem je centralizovan\u00e9 nap\u00e1jen\u00ed. Pokud jsou za\u0159\u00edzen\u00ed nap\u00e1jena p\u0159es PoE switch, lze je snadn\u011bji monitorovat, restartovat a um\u00edstit do sch\u00e9matu z\u00e1lohovan\u00e9ho nap\u00e1jen\u00ed.<\/p>\n

Co PoE d\u00e1v\u00e1 syst\u00e9mu IP interkom\u016f<\/h2>\n

Pro syst\u00e9m IP interkom\u016f<\/a><\/strong> je PoE u\u017eite\u010dn\u00e9 proto, \u017ee syst\u00e9m je ji\u017e vybudov\u00e1n kolem s\u00edt\u011b. Je tedy logick\u00e9, kdy\u017e data i nap\u00e1jen\u00ed putuj\u00ed stejnou infrastrukturou. To je v\u00fdhodn\u00e9 zejm\u00e9na v objektech s n\u011bkolika panely, vnit\u0159n\u00edmi monitory, stanic\u00ed recep\u010dn\u00edho nebo ostrahy, kontrol\u00e9ry p\u0159\u00edstupu a dal\u0161\u00edm s\u00ed\u0165ov\u00fdm vybaven\u00edm. \u010c\u00edm \u010dist\u0161\u00ed je architektura, t\u00edm snaz\u0161\u00ed je \u00fadr\u017eba a roz\u0161i\u0159ov\u00e1n\u00ed.<\/p>\n

I na men\u0161\u00edch m\u00edstech to m\u016f\u017ee m\u00edt svou hodnotu: instalace m\u016f\u017ee b\u00fdt jednodu\u0161\u0161\u00ed a syst\u00e9m obvykle p\u016fsob\u00ed \u00fahledn\u011bji a sn\u00e1ze se servisuje.<\/p>\n

Co je t\u0159eba si p\u0159edem ov\u011b\u0159it<\/h2>\n

PoE je u\u017eite\u010dn\u00e9, ale neznamen\u00e1 to, \u017ee ka\u017ed\u00e9 IP za\u0159\u00edzen\u00ed lze jednodu\u0161e nap\u00e1jet p\u0159es s\u00ed\u0165ov\u00fd kabel bez dal\u0161\u00edho p\u0159em\u00fd\u0161len\u00ed.<\/p>\n

Zaprv\u00e9, samotn\u00e9 za\u0159\u00edzen\u00ed mus\u00ed PoE podporovat. Zadruh\u00e9 mus\u00edte v\u011bd\u011bt, kter\u00fd standard PoE a jakou \u00farove\u0148 v\u00fdkonu vy\u017eaduje. Zat\u0159et\u00ed mus\u00ed tyto po\u017eadavky spl\u0148ovat i switch nebo injektor. I kdy\u017e se ji\u017e d\u00edv\u00e1te na konkr\u00e9tn\u00ed zna\u010dku, jako je BAS-IP, podporu PoE a po\u017eadavky na nap\u00e1jen\u00ed je st\u00e1le t\u0159eba kontrolovat model od modelu. Nelze p\u0159edpokl\u00e1dat, \u017ee ka\u017ed\u00fd IP panel nebo ka\u017ed\u00fd vnit\u0159n\u00ed monitor v r\u00e1mci jedn\u00e9 zna\u010dky je nap\u00e1jen p\u0159esn\u011b stejn\u00fdm zp\u016fsobem.<\/p>\n

Stoj\u00ed tak\u00e9 za p\u0159ipomenut\u00ed, \u017ee ne ka\u017ed\u00e1 \u010d\u00e1st syst\u00e9mu je nutn\u011b nap\u00e1jena stejn\u00fdm zp\u016fsobem. Jedno za\u0159\u00edzen\u00ed m\u016f\u017ee fungovat p\u0159es PoE, zat\u00edmco jin\u00e9 m\u016f\u017ee st\u00e1le vy\u017eadovat samostatn\u00fd nap\u00e1jec\u00ed zdroj.<\/p>\n

Existuj\u00ed n\u011bjak\u00e1 omezen\u00ed?<\/h2>\n

Ano. Jako ka\u017ed\u00e9 technick\u00e9 \u0159e\u0161en\u00ed m\u00e1 i PoE sv\u00e9 limity.<\/p>\n

PoE nezbavuje nutnosti p\u0159em\u00fd\u0161let o kvalit\u011b s\u00edt\u011b, d\u00e9lce kabel\u016f, energetick\u00e9m rozpo\u010dtu a kompatibilit\u011b za\u0159\u00edzen\u00ed.

Jin\u00fdmi slovy, PoE zjednodu\u0161uje syst\u00e9m, ale nenahrazuje kvalitn\u00ed in\u017een\u00fdrstv\u00ed.<\/p>\n

Kdy d\u00e1v\u00e1 PoE zvl\u00e1\u0161tn\u00ed smysl<\/h2>\n

PoE je u\u017eite\u010dn\u00e9 zejm\u00e9na tam, kde je syst\u00e9m IP interkom\u016f budov\u00e1n jako sou\u010d\u00e1st \u0161ir\u0161\u00ed s\u00ed\u0165ov\u00e9 infrastruktury objektu. M\u016f\u017ee se jednat o kancel\u00e1\u0159, reziden\u010dn\u00ed budovu, komer\u010dn\u00ed nemovitost nebo modern\u00ed rodinn\u00fd d\u016fm.<\/p>\n

\u010c\u00edm v\u00edce s\u00ed\u0165ov\u00fdch za\u0159\u00edzen\u00ed v syst\u00e9mu je, t\u00edm z\u0159ejm\u011bj\u0161\u00ed je jeho hodnota: kles\u00e1 pot\u0159eba samostatn\u00fdch nap\u00e1jec\u00edch zdroj\u016f a dal\u0161\u00edch nap\u00e1jec\u00edch veden\u00ed.<\/p>\n

Pokud chcete kr\u00e1tkou verzi<\/h2>\n

PoE je p\u0159enos nap\u00e1jen\u00ed a dat po jedin\u00e9m ethernetov\u00e9m kabelu.<\/p>\n

Pro IP interkomy je u\u017eite\u010dn\u00e9, proto\u017ee zjednodu\u0161uje instalaci, \u010din\u00ed syst\u00e9m \u00fahledn\u011bj\u0161\u00edm, pom\u00e1h\u00e1 centralizovat nap\u00e1jen\u00ed a p\u0159irozen\u011b zapad\u00e1 do s\u00ed\u0165ov\u00e9 architektury.<\/p>\n\n\n
