Ubude obugxilile bamalensi asetshenziswa kumakhamera okuqapha ekhaya ngokuvamile busukela ku-2.8mm ukuya ku-6mm. Ubude bokugxila obufanele kufanele bukhethwe ngokusekelwe endaweni ethile yokugada kanye nezidingo ezingokoqobo. Ukukhethwa kobude bokugxila kwelensi akuthinti nje kuphela indawo yokubuka yekhamera kodwa futhi kuthinta ngokuqondile ukucaca kwesithombe nokuphelela kwendawo egadiwe. Ngakho-ke, ukuqonda izimo zohlelo lokusebenza zobude obuhlukile bokugxila lapho ukhetha okokusebenza kokugada ekhaya kungathuthukisa kakhulu ukusebenza kokuqapha nokwaneliseka komsebenzisi.
Ububanzi obujwayelekile bokugxila obujwayelekile bamalensi:
**2.8mm ilensi**:Ifanele ukuqapha izikhala ezincane ezinjengamakamelo okulala noma iziqongo zamawodrobhu, le lensi inikeza indawo yokubuka ebanzi (imvamisa engaphezu kuka-90°), ivumela ukumbozwa kwendawo enkulu. Ilungele izindawo ezidinga ukugadwa okubanzi, njengamagumbi ezingane noma izindawo okwenziwa kuzo izilwane ezifuywayo, lapho ukubuka okubanzi kubalulekile. Ngenkathi ithwebula uhla olubanzi lokunyakaza, ukuhlanekezela okuncane konqenqema kungase kwenzeke.
**4mm ilensi**:Idizayinelwe izindawo ezimaphakathi nezinkulu njengamagumbi okuhlala namakhishi, lobu bude bokugxila buhlinzeka ngenhlanganisela elinganayo yenkundla yokubuka nebanga lokuqapha. Nge-engeli yokubuka ngokuvamile ephakathi kuka-70° no-80°, iqinisekisa ukumbozwa okwanele ngaphandle kokuphazamisa ukucaca kwesithombe ngenxa ye-engeli ebanzi ngokweqile. Kuyindlela evame ukusetshenziswa ezindaweni zokuhlala.
**6mm ilensi**:Ilungele izindawo ezinjengamaphasishi namavulandi lapho kokubili ibanga lokuqapha nemininingwane yesithombe ibalulekile, le lensi inendawo yokubuka emincane (cishe u-50°) kodwa iletha izithombe ezicijile kumabanga amade. Ifaneleka ngokukhethekile ukuhlonza izici zobuso noma ukuthwebula imininingwane enemininingwane njengamapuleti emoto.
Ukukhetha ubude bokugxila kwezinhlelo zokusebenza ezikhethekile:
**amalensi angu-8mm nangaphezulu**:Lezi zilungele ukuqapha indawo enkulu noma ibanga elide, njengasezindlini zama-villa noma emagcekeni. Zihlinzeka ngezithombe ezicacile emabangeni anwetshiwe futhi zisebenza kahle kakhulu ekuqapheni izindawo ezifana nothango noma iminyango yegaraji. Lawa ma-lens avame ukuza namandla okubona ebusuku nge-infrared ukuqinisekisa ukuthwebula kwekhwalithi ephezulu ebusuku. Nokho, ukuhambisana nedivayisi yekhamera kufanele kuqinisekiswe, njengoba amanye amakhamera asekhaya angase angawasekeli lawo malensi efoni. Kunconywa ukuthi uhlole imininingwane yedivayisi ngaphambi kokuthenga.
**3.6mm ilensi**:Ubude obujwayelekile bokugxila kumakhamera amaningi asekhaya, bunikeza ibhalansi enhle phakathi kwenkundla yokubuka nebanga lokuqapha. Nge-engeli yokubuka ecishe ibe ngu-80°, ihlinzeka ngesithombe esicacile futhi ifanele izidingo ezijwayelekile zokuqapha ikhaya. Lobu bude bokugxila buguquguquka futhi bubiza izindleko eziningi zezicelo zokuhlala.
Lapho kukhethwa ubude bokugxila belensi, izici ezifana nendawo yokufaka, ubukhulu bendawo, kanye nebanga eliya endaweni okuqondiswe kuyo kufanele kucatshangelwe ngokucophelela. Isibonelo, ikhamera efakwe emnyango ingase idinge ukuqapha kokubili umnyango kanye nephaseji eliseduze, okwenza ilensi engu-4mm noma 3.6mm ifaneleke kakhulu. Ngokuphambene, amakhamera amiswe kuvulandi noma ekungeneni kwegceke afaneleka kangcono amalensi anobude bokugxila obungu-6mm noma ngaphezulu ukuze kuqinisekiswe ukuthwebula izithombe okucacile kwezigcawu ezikude. Ukwengeza, kunconywa ukubeka phambili amakhamera anokugxila okulungiswayo noma amakhono okushintsha ubude obugxile ezintweni eziningi ukuze kuthuthukiswe ukuzivumelanisa nezimo kuzo zonke izimo ezihlukahlukene futhi ahlangabezane nezidingo zokuqapha ezihlukahlukene.
