Esikhathini sethu, inkinga yokuphepha ihlupha abantu abaningi. Izinhlelo zokuphepha ezihlukahlukene ziye zaba yingxenye enkulu yamahhovisi, amabhizinisi kanye namafemu, kodwa nezindlu zangasese nezindlu zangasese. Yiqiniso, isisombululo esifanele senkinga yokuphepha kwempahla yangasese ukufakwa kwezingodo ezinzima, i- lever noma i- electromechanical , kanye nesistimu yokuqapha ividiyo engapheli, kodwa lolu hlelo ngeke lukwazi ukukhokhela wonke umuntu. Kodwa intuthuko yezobuchwepheshe ayimi futhi isibhamu sokuvikeleka ekhaya sihlale sigcwaliswa ngezinto ezintsha. Enye yalavelties yayiyividiyo yomnyango - idivayisi, efakwe emnyango wangaphambili esikhundleni somnyango ojwayelekile futhi iqukethe i-lens nekhamera yevidiyo. Le divayisi ikuvumela ukuba ubukele kude kwi-TV noma ividiyo ukuqapha konke okwenzeka ngemuva komnyango wokungena.
Indlela yokukhetha iso levidiyo?
Okokuqala, udinga ukuxazulula lo mbuzo - kungani udinga i-eye iso nokuthi yimiphi imisebenzi oyoyenza? Mhlawumbe ufuna ukwenza impilo yakho ibe lula futhi ngale divayisi ofuna ukwazi ukuthi ubani oza kuwe, engafiki emnyango, futhi mhlawumbe udinga amahora angu-24 okubukwa kwevidiyo efihlekile, ulwazi lokurekhoda nokulondoloza ku-DVR.
Ngakho-ke, kuye ngokuthi yizintandokazi zabo, kanye namathuba ezezimali, umthengi ngamunye angathenga:
- Iso levidiyo elimnyama nelomhlophe ngekhamera yevidiyo. Inzuzo yalo enkulu yizindleko eziphansi kakhulu, futhi ukungalungi kuyisinqumo esincane se-matrix yevidiyo kanye nokwahlukana okusobala kusuka emnyango-eyejwayelekile;
- Icala le-video elimnyama nelomhlophe ne-IR yokukhanyisa. Le ikhamera inesinqumo esihle kakhulu, ukufakwa okulula, kodwa izindleko zayo cishe izikhathi ezimbili eziphakeme kunezindleko zekhamera yevidiyo;
- I-eye yevidiyo yohlu. Yiqiniso, inzuzo enkulu yale divayisi ngumfanekiso wombala, kodwa ikhwalithi yayo ingaphansi kwe-case-white-white-video-eyes, ngaphandle kwalokho, intengo yayo iphezulu kakhulu.
Ngaphezu kwalokho, ngokusho kwendlela ulwazi oludluliselwa ngayo futhi oluqoshiwe, amehlo omnyango womnyango aphethwe futhi angenawo ucingo, i-analog ne-digital.
Futhi, lapho ukhetha iso levidiyo, kufanele uqaphele i-angle yokubuka. Ngokwale nqubo, okwamanje kunezinhlobo ezimbili zamehlo ane-angle yokubuka ye-160 ° -180 ° no-90 ° -120 °. Ngakho-ke, uma umnyango wakho wangaphambili ungaseceleni komgudu, khona-ke imodeli kanye ne-angle yokubukwa esiphezulu ifanelwe wena, ukuze ukhiphe ukungabikho kwemininingwane. Futhi ngomnyango osekupheleni kwezitebhisi, amakhamera ane-angle yokubuka efika ku-120 ° ayokwanela, okuvumela ukuba ubuke okwenzekayo kude kude namamitha amathathu.
Izici ezengeziwe zomnyango wevidiyo
Uma udinga ukubukwa kwevidiyo yamahora angu-24 kufanelekile ukukhetha ukuqoshwa kwevidiyo emnyango ngokuqoshwa. Ngalo msebenzi, wena
Futhi ekuthengisweni kuyizinhlobonhlobo zamehlo wevidiyo ngesinzwa sokuzwakalisa ngaphakathi. Lo msebenzi usebenza ukusebenza kwedivayisi ngokunyakaza okuncane kuhlaka, ngisho nasezimweni zokukhanyisa okuncane.
