Umbhobho Kuhle kakhulu video ukubhekwa

Isiqophi ukubhekwa izinhlelo ngokwemvelo ngamakhasimende ukuhlinzeka ngolwazi ezibukwayo ngalokho okwenzekayo endaweni Ukusabalala. Classic software enzima ezokuphepha kuhlanganisa camcoder compact, futhi umdlalo ukusekela kanye tooling for ukuthumela idatha ku-elawulwa kude. Ukurekhoda umsindo zize kamuva, futhi ezimweni eziningi futhi ayisekelwa yi ikhamera. Kunengqondo ukuphetha ngokuthi le nkinga ingaxazululwa ukuthenga imodeli sokuqala lapho umbhobho okuhlangene - amadivaysi ezinjalo ziyatholakala futhi ezimakethe.

Nokho, indlela esakhelwe zokuqopha umsindo akuyona umphumela engcono izimfanelo ngamunye eqhuba apharathasi, kodwa ngisho isici esibalulekile ngaphezulu indawo yayo. umbhobho Compact for video ukubhekwa, ngokungafani kuya ikhamera, akufanele walubeka wokubuka elikhulu, futhi ezindaweni ezikahle kakhulu ekuthwebuleni umsindo. Ngamanye amazwi, ukucushwa ephumelela kunazo iyohlukanisa nokubekwa amakhamera imibhobho ngokufanele. It uhlala kuphela ukukhetha imodeli elikhulu esikude lwedivayisi.

imodeli yekwentiwa - okuyinto engcono?

Umehluko phakathi kwalezi zinhlobo imibhobho, njengoba kwaba njalo endabeni ka-imishini umnyuziki acoustic uhlala indlela isignali okhulisa. Endabeni lamadivayisi engabe yokugcizelela ukudidiyelwa kwangaphakathi module ku-design. Le ndlela lithuthukise ukucutshungulwa isignali kanye ne-transmission izinqubo esifanelana ngokuphelele ku nomqondo tekusebenta futhi functional Ukuvikelwa eziyinkimbinkimbi. Nokho, i-microphone asebenzayo video ukubhekwa kudinga ukulungiselelwa eyengeziwe futhi akakwazi ukwenza umsindo omkhulu ovela ngemuva Imi egcwele.

imodeli Passive yena, sisebenze msindo ozinikele, ukwakha esinye isixhumanisi ekudluliselweni chain. Lokhu ashukumisayo signal processing ubuchwepheshe ulungisiswa ekuxazululeni imisebenzi ekhethekile neqoqo elilinganiselwe imisebenzi. Active modeli sibonga inzuzo engaphezulu yizinhlobonhlobo evumela ukuthi ukuba lisetshenziswe ezihlukahlukene ukucupha ka zokuvikela.

izici eziyinhloko imakhrofoni

Imishini enjalo akudingi ukudalwa izimo ekhethekile ngokohlelo lokuhlelwa amandla, kodwa ikhono ukusebenza umsindo kubalulekile ukuhlola esinyathelweni Ukukhetha. Isici esiyinhloko sale okuyingxenye ngeke isukela, okungukuthi, Ukusabalala isignali. Ngo imibhobho ezivamile, lokhu ipharamitha sivezwe ukuzwela, kodwa kulokhu kuphela abakhiqizi ukhombise ibanga - ke ezomhlaba 5-7 amamitha Kukhona kunakwe, futhi komkhawulokudonsa imvamisa uhla, okuzokwenza anqume izinga ukuqopha .. isabelomali version ejwayelekile, isibonelo, usebenze nomkhakha we 20-20 000 Hz. Lokhu kwanele wokucubungula inkulumo. Kuyadingeka ukuba ucabangele izinto zokuzivikela, ezizohlinzeka microphone for kwamakhamera enkabeni ukuguqulwa esithile. Kuye indawo isicelo kungadingeka ebiyelwe flameproof, Uhlaka ukumelana noma ukwahlukanisa kusuka umswakama. Acabangele izindleko kanye imiphumela lokushisa - ngokuvamile apharathasi enjalo isebenza stably at the rates eliphakeme aphansi futhi.

Izici IP-microphone

IP-Surveillance uhlelo Sekuyisikhathi eside ithathwa njengendlela wodwana amadivayisi zokuzivikela. Ukuvela imishini inethiwekhi kule ndawo yiyona kuphela omunye izigaba akunakugwenywa nokuthuthukiswa kwezinhlelo digital okuyinto ngenkuthalo esikhundleni imishini analog. Yiziphi amakhamera IP-surveillance nge umbhobho? Empeleni, i-imishini esezingeni digital, elibuye kusekela ikhono ukusebenza iziteshi kwenethiwekhi.

Okungukuthi, kwakheka yesibambiso ingqalasizinda esihlanganisiwe esekelwe ubuchwepheshe kwenethiwekhi, futhi iseva noma iqembu amaseva. Ngokombono msebenzisi indlela ebalulekile ikakhulukazi nokuxhumana yezingxenye ngamunye - umbhobho wokukhuluma owodwa kanye nokulawula ikhamera iyunithi. Lokhu inkinga ingaxazululwa futhi ngendlela yezintambo ngokusebenzisa i-Ethernet inethiwekhi Namandla Over imishini noma tech engenantambo module-Wi-Fi.

Izibuyekezo imifanekiso Stelberry

Inkampani Stelberry ezinabantu emelelwa kule ingxenye. Onjiniyela yenkampani ukunikela kudivayisi ebucayi kakhulu ebanzi imvamisa ibanga amathuba ukulungiswa nemingcele ukhiye. Abanikazi Stelberry imibhobho ukhombe lomsebenzi olesithunzi umkhiqizo izinga, linokwethenjelwa mechanical nokusebenza. I ukugcwaliswa kwangaphakathi ivikelwe eliphezulu plastic nensimbi, okuvumela ukuba usebenzise i-microphone ukuze video ukubhekwa, hhayi kuphela ekhaya kodwa futhi emgwaqeni. Nokho, ochwepheshe batusa namanje futhi anikeze Ukuvikelwa ozimele ngenxa yokushaqeka umphumela.

Izibuyekezo imifanekiso SoundMonitoring

Futhi akekho noyedwa kulaba baholi emakethe alalelwayo, okuyinto akhiqizwa ngaphansi brand wesimanje onobuhle imibhobho ezihlangene. Imikhiqizo efanayo ingase ikumangaze SoundMonitoring? Ngokusho abasebenzisi, imodeli asebenzayo alo mkhaya zinezikhathi isebenza ngendlela efanele ngaphansi kwezimo umsindo kuma. Okungukuthi, abadali kugcizelelwa ukugcwaliseka umsindo ukucindezelwa izinhlelo - ngenxa okukhiphayo uya material nangomsindo ehlanzekile enemininingwane. Kumakrofoni ukubhekwa ukubeka eceleni imisindvo target yangaphandle ukugeleza Imininingwane, umsebenzisi futhi unethuba ulungise izihlungi ngabanye at amaza ezahlukene.

Uphenyo "Byterg" onobuhle

Lena nomkhiqizi yasekhaya ezikhethekile nemishini video ukubhekwa. In the line amakhasimende yenkampani ikakhulukazi bayakwazisa imodeli amancane IAC-M022. Kuyinto asebenzayo ezimbili wire umbhobho, esinikela ikhono ukusakaza isignali olude. Ngokomthetho, ukudluliswa kungenzeka at ibanga cishe ngo-1000 m. Ngaphezu kwalokho, phakathi isikhundla futhi ifayela amalungu e-microphone ukuze video ukubhekwa ku yeThemu yesi-M022 ukuguqulwa zenani ngoba ikhono ukuxhuma kwi-ezobuchwepheshe kanye analog. Nokho, kwezinye izimo, idinga ukuthola decoders akhethekile abalobi.

Indlela ukukhetha umbhobho engcono?

Kukhethwa ngeke ngokuyinhloko ixhomeke ekutheni isicelo kanye nezidingo interface uxhumano. Ngesikhathi esifanayo, yebo, kudingeka sinake umthamo ukuqoshwa. Ukusetshenziswa ekhaya kungenziwa akulinganiselwe imodeli ejwayelekile digital yohlobo esebenzayo, okuyinto ixhunywe parallel control panel egumbini ngokusebenzisa ucingo. Uma ukhona umbhobho adingekayo video ukubhekwa izinhlelo e izinto ezibucayi ngokulondeka izinhlelo eziyinkimbinkimbi, kunengqondo ukuba baphendukele onobuhle esekela ukuxhumana kwenethiwekhi. Lolu khetho ngeke bathethelele uqobo, futhi ngenxa yezizathu zezomnotho, futhi ngeke lula izinqubo zemvelo ingqalasizinda inhlangano.

umbhobho uxhumano

Uma uxhumo lezintambo ngokuvamile kufanele ukusebenzisa iziteshi ezintathu. Ababili babo ukunikeza amandla, futhi isenzo wesithathu nokwaziswa transmission umugqa. Nalapha futhi, nanti iphuzu lokuqala lapho ama-signal kanye ne-amplifier bangase benze njengokungathi kungokuqondene amadivayisi yokwenziwa, futhi elawulwa kude uhlelo ngqo. Umbuzo ukuthi uxhume i-microphone ukuze video ukubhekwa ngokusebenzisa inhlangano inethiwekhi, wanquma sokushona yezifiso kanye ne-software. Lapha-ke kubalulekile kakhulu ukuthi ukuhlobana phakathi izingxenye software. Ngokuvamile, i-IP kudivayisi bephethe isofthiwe nokuphathelene, nobunzima inqubo kangaka yokuxhuma-microphone ukuze owamukelayo, akumelwe ukuvimba noma ukubanga cell. Ngokuvamile, kulungiselelwa wenziwa ngokuzenzakalela emva ecacisa idatha yomthombo eziyisisekelo.

isiphetho

Nakuba unganakile iinthombe umbhobho uhlelo ukubhekwa ubonakala nzima, ingxenye esisebenzayo ekuqalisweni kwalo msebenzi abasakwazi uyakwazi abasebenzisi ngisho lutho. Ngaphezu kwalokho, izindleko lo mcimbi bathethelele ngokugcwele umsebenzi ukurekhoda ukuqinisekisa ukuphepha. Ngokwesibonelo, yesimanje IP-Surveillance umbhobho angathengwa ayizinkulungwane 2-3. Hlikihla. Futhi lokhu kusebenza eliphezulu onobuhle ezivela abakhiqizi elikhulu okukhulunywe ngalo. Nokulungiswa elula ishibhile - inokudla ingatholakala ezingeni intengo ruble kuze kufinyelele ayizinkulungwane 1 .. Kukhona ngempela isabelomali izixazululo akalahlekelwanga ruble esingaphansi 500. Kodwa lokhu kukhetha engcono kugwenywe, ngoba ukukhiqizwa ngokungagwegwesi ezishibhile izodlala hhayi kuphela ukusebenza, kodwa futhi ukuthembeka ukugcwaliswa yangaphakathi.
