Uma uzama ukukhetha ikhamera yokubhekisisa
Isinyathelo sokuqala ekuqinisekiseni isixazululo esihle sokuphepha ukufana nezidingo zokumboza enanini lamakhamera. Ingabe amakhamera afakwa ngaphandle, ngaphakathi, noma womabili? Ngabe kuzoba nekhamera eyodwa ebheka ingxenye ethile yekhaya (njengekhamera yomnyango), noma ukumbozwa kwangaphandle okugcwele kuzodingeka? Enye into okufanele icatshangwe - ingabe udinga ukuhlola ividiyo ebukhoma usuku lonke, futhi abantu abaningi bafuna ukubuka le vidiyo? Uma kunjalo, ama-webcams angahle alungele njengoba evumela ividiyo ukuthi isakazwe nge-Intanethi futhi ifinyeleleke kude.
Lapho lezi zinto zikhonjwe, isinyathelo esilandelayo ukuthola ukuthi yisiphi isisombululo esilingana kangcono nezidingo. Isidingo esizungezile ukuqinisekisa ukuqoshwa kombono osezingeni eliphakeme kakhulu. Ngenkathi i-4K ayidingekile (ngaphandle kokuthi lokho kukhethwa), okokufaka kwevidiyo kufanele kube okuseqophelweni eliphezulu ngokwanele ukubona ubuso noma amapuleti welayisense imini nobusuku ukuze kube yisixazululo esiphelele sokuphepha.
1. Funda ngezinhlobo ezahlukahlukene zekhamera yezokuphepha ezitholakalayo: Amakhamera wezokuphepha e-infrared (IR). I-Dome Camera Professional Camera Camera Pan Zoom Camera efihliwe Ikhamera 2. Izinzuzo zamakhamera wezokuphepha e-infrared (IR). Le ikhamera ethandwayo yebhizinisi nasekhaya. Amakhamera we-infrared akhiqiza ividiyo ephezulu yombala phakathi nosuku. Zinguhlobo lwekhamera olukhethwayo eLow Lux (Light) noma izimo ezingenampilo. Bayakwazi "ukukhanyisa indawo" ngokushintsha ngokuzenzakalelayo kusuka ku-Colour kuya kumnyama nomhlophe. I-IR I-IRLLINATER iyaphenduka, ikuvumela ukuthi ubone iso lomuntu ngokucacile ezimweni eziphansi nezingenakukhanya. Noma ngabe kusetshenziswe ngaphakathi ngaphakathi noma ngaphandle, banikeza inzuzo enkulu ezimeni eziphansi noma ezingenakukhanya. Bangamazinga okushisa isimo sezulu futhi bangamelana namazinga okushisa ashisayo namakhaza ngaphandle kwezindlu zekhamera ezengeziwe. Amakhamera we-Infrared Infrared anikezela ngezithombe zevidiyo ezicacile ekukhanyeni nasebumnyameni. 3. Izinzuzo ze-Dome Cameras. Izitayela ezahlukene zama-domes zifaka phakathi ama-infrared domes, i-Indoor Domes, izindawo zangaphandle, izindawo ezingalawulwa yi-vandal kanye ne-pan-zilt-zooms okulawulwayo. Amakhamera we-DOME "ashumekayo" ahlinzeka ngokubhekisisa okwengeziwe, ngoba kunzima kubangani, amaklayenti, abasebenzi kanye nokuphalada ukubona lapho empeleni i-footage empeleni ikhomba lapho empeleni i-footage empeleni ikhomba khona. Isembozo esibhemayo ngeke sithinte ikhwalithi yesithombe. Izithombe ezicacile zemibala zitholakala ngekhamera ye-dome iningi lamakhamera we-pan-tolt-zoom futhi libonisa izindlu zohlobo lwe-dome-hlobo. Amakhamera we- "Box" asebenzisa izindlu zekhamera zombili ngaphakathi nangaphandle 4. Izinzuzo zamakhamera ochwepheshe. Lawa makhamera ayaziwa ngekhwalithi yawo ephezulu yevidiyo. Amakhamera webhokisi le-Professional ajwayele ukutholakala emabhange, ezitolo ezinkulu, ezitolo ezilula, njll. Amalensi angashintshwa kwikhamera ye-Pro ngokuya nge-angle efiselekayo yokubuka nokusondeza. Amanye amakhamera e-Pro BOX abizwa ngokuthi amakhamera we-Day / ebusuku ngoba angashintsha kusuka kombala phakathi nosuku kuya kubuningi obumnyama namhlophe noma obuphansi (ngezimo ezikhanyayo) ebusuku. I-Low the Lux, ikhamera engcono ingabona ebumnyameni obuphelele. Amakhamera we-infrared abhekwa njengamakhamera we-night Vision futhi anesilinganiso esingu-0 lix. Uma ungadingi noma ufuna infrared, futhi ukhathazekile kakhulu ngevidiyo esezingeni eliphakeme yesikhathi sosuku, ungahle ukhethe ikhamera yebhokisi. 5. Izinzuzo zekhamera ye-Pan-Tilt-Zoom. Lawa ngamakhamera angalawulwa nge-DVR, isoftware yokubuka kude, kanye / noma induku yokudlala. Bangakwazi ukuhamba phezulu, phansi, kwesokunxele nakwesokudla. Futhi banamakhono okusondeza.
Isibonelo, ungathwebula ipuleti yelayisense noma usondeze ebusweni obude. Ungase futhi uhlele ngezihambeli ezisethiwe, lapho ungabheka khona izindawo ezithile ngenkathi uphumile futhi cishe. Izikhumulo zezindiza, amakhasino, izitolo ezinkulu zoMnyango ezifana neRainbow noma iDarunjia zonke izindawo zokusebenzisa i-PTZ (Pan Tilt Zoom Cameras). Amakhamera wePan-zoom ayabiza, aqala ngaphezulu kwama-3,000 yuan. Umbuzo uwukuthi, "Udinga ikhamera ye-Pan-Tilt-Zoom", noma ingabe ikhamera ehleliwe ingasetshenziselwa ukuthola ikhambi oyifunayo? Amakhamera alawulwa yi-Pan-zoom adinga ikhebula elengeziwe ukuze lisebenze. Ngaphezu kwekhebula le-Power / Video RG-59 Siamese Coaxial Cable, ikhebula lekati liyadingeka ukuze alilawule ngesikhathi sangempela nge-Intanethi. Vele usebenzise ikhebula lekati eliseduze ne-RG-59 ukulawula ikhamera ye-Pan-Tilt-zoom. 6. Izinzuzo zamakhamera afihliwe. Lokhu kungenzeka kunikeze ngezinga eliphakeme kakhulu lokubhekwa. Uma ungafuni muntu azi ukuthi kukhona ikhamera, sebenzisa ikhamera efihliwe. Imishini yokutholwa kwe-Fake Smoke, ukutholwa kokunyakaza, amawashi, ama-sprinklers, izimpawu zokuphuma kuyizibonelo zezinhlobo zamakhamera afihliwe asetshenzisiwe. I-Main Downside yilowo amakhamera afihliwe awanawo amandla angezinkinga, anciphisa ukusebenza kwawo ezimeni eziphansi. Futhi, amakhamera amaningi afihliwe awawona isimo sezulu, ngakho-ke awasizi njengamakhamera we-infrared kanye namakhamera we-dome lapho asetshenziswa ngaphandle. Amakhemisi, amakhekhe amahhotela, izikhungo zokuphila ezisize, namakhaya anezibonelo zezicelo lapho kusetshenziswa amakhamera afihliwe. 7. Nquma ukuthi ufuna ikhamera entanjeni noma engenantambo. Amakhamera wentambo anikela ngevidiyo eningi futhi, okubaluleke kakhulu, ikhwalithi yevidiyo engcono kunekhamera engenantambo. Amakhamera angenantambo angaba yidukisa ngoba adinga amandla endaweni yekhamera. Futhi, badinga umugqa wokubona ngaphandle kokuvinjwa, okuvame ukudala izinkinga. Ukwethembeka nekhwalithi yevidiyo yizizathu eziphambili zokuthi kungani kufanele usebenzise ikhamera ephineliwe. Amakhamera we-Wired abizwa emuva endaweni ye-DVR, kanye nekhebula elilodwa nje (RG-59 Siamese Coaxial Power / Video Conbo) lisebenza kusuka ku-DVR kwikhamera ngayinye. Ngale ntambo ekhethekile, ungaqhuba ikhamera kusuka kubanga elifinyelela kumamitha angama-243.8). Uma kungaphezulu kwamamitha angama-800 (amamitha angama-243,8), uzodinga ukusebenzisa ikhebula le-Cat5 nge-balun yevidiyo kanye / noma i-amplifier. Usebenzisa ikhamera ephineliwe inempilo ende nekhwalithi ephezulu. Amakhamera anentambo awaveli izithiyo. Ngalokho engqondweni, ngezikhathi ezithile ungaba nezindawo ezimbili lapho uludinga khona. Kulokhu, ungafaka i-transmitter ibe emuva kwe-DVR. 8. Izinhlobo ezahlukene zamakhamera ezokuphepha - Ahd, HD-SDI, HD-CVI, HD-TVI ne-IP.
Fingqa: Thanda amakhamera we-High-resolution, ungalindela ukuba abe yikhwalithi enhle kakhulu njengamanye amakhamera amaningi emakethe. Amakhamera angenhla kwe-480p (ebizwa ngokuthi ukulungiswa okuphezulu ngokuqhathaniswa nokulungiswa okujwayelekile kwe-380 nama-420p amakhamera) yinani elihle. Kukhona manje amakhamera we-Ultra-high-resolution anezinqumo ezingaphezu kuka-1080p. Khetha ikhamera ngokususelwa kuhlelo lwakho lokusebenza. Izindawo zesimo sezulu ezishubile ezidumile ngaphandle kakhulu, ngenkathi amakhamera we-dome ethandwa izicelo zasendlini. Onke amakhamera ahlukile futhi anikela ngamakhono angaphandle, angaphandle noma angenampilo. Ukuthola ukuthi yimaphi amakhamera athandwa kakhulu, abuze abathengi abasetshenzisiwe nabafaki.
