Isiqophi ukubhekwa Analog: incazelo, izici, izinhlelo kanye nokubuyekeza

imishini Analog akuyona onyakeni wokuqala ukubikezela imali ebhange ogcwele kusuka emakethe, njengoba sekuke kwenteka nge ikhasethi abalobi. Noma kunjalo, ngisho ngokumelene isizinda intuthuko kwezokuxhumana njengoba ukuvela wireless ukuthumela idatha amamojuli, futhi ngokuqhubekayo ngcono format ephezulu definition, le ngxenye asindiswe. Futhi uma niche multimedia ubuchwepheshe cishe imperceptible, le CCTV Analogue kuphazanyiswa imishini digital.

ulwazi olujwayelekile mayelana isiqophi analog

Lena wendabuko video ukubhekwa izinhlelo, okuyinto ezidla ngokusebenzisa ikhebula coaxial bese uxhuma rekhoda analog. Uyisisekelo sesethi ikhamera yevidiyo ngokuqondile, okungase futhi ezahlukene sokudubula izimo. I esetshenziswa njalo kunazo analog isiqophi amakhamera for video ukubhekwa yohlobo isabelomali. Basuke izimpawu ezinombala ofanayo "isithombe" lens prime nge beso esinqunyiwe kanye ukuntula kwakhe ikhono ukushintsha ubude ebalulekile. Ngokuphambene, onobuhle premium zinezikhathi kwencazelo eliphezulu izithombe umbala ukudluliswa ukuthi akudingeki ukulinganiselwa ngokuya ikhono ukusebenza ezimweni ezehlukene sezulu.

Kulesi uhlelo uxhumano cishe njalo ejwayelekile. Ikhamera ixhunyiwe ku-umthombo wamandla (ngokuvamile ezizimele ugesi) nasekufuyeni isignali rekhoda kokwenza. Isignali eye eqoshiwe analog video ukubhekwa, ingase ithunyelwe qapha dispatcher noma kungobo yomlando kunethiwekhi.

izici zezingxenyekazi zekhompyutha

amakhamera ngokuqondile-matrix kuqhathaniswa onobuhle digital elifanayo zikuvumela ukudubula kwekhwalithi ephezulu yevidiyo, kungakhathaliseki ukuthi ukukhanyisa nemininingwane ukuze uthwebule izinto kunyakaza. Ngokuphathelene ingqalasizinda jikelele zokugada analog, kuba mahhala kuzo zonke bokwenza esivela IP-kumadivayisi. Lokhu kuhlanganisa ukubambezeleka ukuthumela idatha, amagciwane e iziteshi inethiwekhi, sakugcina nokugcinwa izindleko, nokunye. D.

Kodwa-ke le ngxenye izinzuzo futhi okunemibandela, njengoba emhlabeni wanamuhla akukwazi uyisehluleki cishe kusukela imishini digital. Ngakho-ke, lapho besanda of isignali yokuguqula mibhalo nengqalasizinda ebhekene nezinkinga "digital". Yiqiniso, zikhona amaningi izici ezingezinhle ukuthi isono analog CCTV - IP-ikhamera, esikhundleni salokho, abe ngemuva okungafani engibukhulumile ngaso lezi kwamaphutha ziyabonakala ngokucacile. Lezi zihlanganisa ukuphazamiseka kagesi emigceni ukudluliswa, ukuntuleka okubanzi ukuphathwa amakhono esikhathini sangempela, exclusion umqondo engenantambo.

izakhiwo ezintsha

Enye yezinkinga ezinkulu e mncintiswano yesimanje ifa analog amakhamera amazinga ongaphakeme definition. Eqaphela lesi simo, abakhiqizi abaningi baye bahlakulela eziningi izakhiwo ezintsha analog, kuhlanganise HDCVI futhi HDTVI.

Izinga lokuqala libhekene isignali ukusakaza usebenzisa quadrature amplitude kwezwi. Lokhu kusho ukuthi ukusakaza ihlukene kanengi zibe iziteshi eziningana, okuyinto zihlukaniswe, isibonelo, iLuminance futhi chrominance amasignali. Amadivayisi ngalesi sakhiwo uvumele ukunikeza amasignali ezintathu ngokusebenzisa ikhebula olulodwa. Phakathi kwabo kuyoba khona audio, video kanye umyalo izimpawu ubuchwepheshe isilawuli PTZ. Lokhu analog CCTV uhlelo yesimanje, okuthiwa ikhono lokulawula ikhamera nge ikhebula - isibonelo, umsebenzisi angakwazi ukunqophisa ngezindodla idivayisi "isithombe", ukushintshanisa ukwakhiwa kwezindlu, njll ...

HDTVI ubuchwepheshe, esikhundleni salokho, libhekene ezimbili ngendlela uhlelo ukudluliswa, amasignali control PTZ, kodwa ngesikhathi esifanayo, uma iqhathaniswa naso onobuhle HDCVI uyabavikela enganele ngokumelene ukuphazamiseka.

Izinhlelo ngokusebenzisana amasignali analog

Njengoba izixazululo elula ukusebenza abaphendukile analog isignali ikhamera kungenzeka Kunconywa Uhlelo CamPermanent. It has a base kulolu hlobo software ukusebenza, kodwa okuthembekile nokulula - ekhaya video ukubhekwa isixazululo esingcono.

Uma kuhlelwe ukuhlela ingqalasizinda kuhlanganiswe ngokuhlanganisa izakhi IP-imishini futhi analog amasignali, kufanele usebenzise "Videolokator" uhlelo, oyoletha ndawonye zibe munye eziyinkimbinkimbi wonke imishini alamu.

I professional isixazululo analog CCTV sipho Onjiniyela NVR SMARTEC. Lolu hlelo ikuvumela ukuba ahlele izakhiwo "amaklayenti-server", lapho inethiwekhi uhlelo ukubhekwa isiqophi izokwakhiwa.

abanikazi Izibuyekezo

Iningi analog abasebenzisi uhlelo - abathengi, ngubani, ngenxa yokuntuleka kwezimali, ayikwazanga ukuthuthela uhlelo digital. Bayakwazisa analog kusho ukuyikhokhela, le Ukujwayelana sokwelashwa asikho isidingo sokuba kwakhiwe kabusha ingqalasizinda ikhebula.

Iqiniso liwukuthi e izinkampani eziningi ukuthi sisebenza inakekelwa inethiwekhi coaxial esingavunyelwe ahambisana ne-IP amakhamera. Ngakho, kuyisinyathelo uyasicabangela ezinjalo ukufaka imishini ehambisanayo. Ngaphezu kwalokho, lo mkhuba ukuxhashazwa akusho ngaso sonke isikhathi uqinisekise ukuthi analog CCTV kubonakale kunabayeni khamera. Abasebenzisi ngokwabo akuvamile akhononde izinga yesithombe, ukuhlanekezela noma ukwehluleka emgqeni. Enye into ukuthi ngokuya pluses nezokuxhumana amakhono ngaphezulu iyona "sibalo", kodwa hhayi amathuba amasha njengoba owawubalulekile iningi abathengi.

isiphetho

izixazululo zanamuhla kwezobuchwep umsebenzisi uvule uhlelo olubanzi imisebenzi emisha e-ndlela eziningi ezahlukene. Kulokhu, kukhona imikhiqizo luyingxenye ukumaketha, SIZUZISA okuyinto ngokulambisa lizwakale. Ngokwengxenye ngenxa ukukhangisa elikhulu futhi digital amakhamera e-CCTV analog eminyakeni embalwa okwandile edlule kubonakale elahlekile phansi. Ingxenye lesichubekako kakhulu abathengi ngokuzithandela kwi ngesakhiwo esisha, kokuba eziningi eziwusizo. Kulesi sigaba, camcorders analog, onjiniyela ozama dlweza lo ingxenye, ngoba unalo eside engaba ezimbonini.
