Ukulinganisela Kunqoba Izimfanelo Eziphakeme Njalo
Uma kukhulunywa ngokuxazululwa kwe-USB yekhamera kanye ne-FPS, iphutha elikhulu ongayenza ukujaha izinombolo eziphakeme kakhulu ezikhanyisiwe ebhokisini lomkhiqizo. Ukusebenza okuphezulu kwe-USB yekhamera akubangelwa ukukhuphula zombili izici—kuvela ekulinganiseni okuhlosiwe, okugxile ekusetshenzisweni, okuhambisana nezidingo zakho zansuku zonke, imikhawulo yehadiwe, kanye nokuhlelwa kokubuka.
Kubasebenzisi abangu-90%, i-1080p ku-30 FPS iyisilinganiso esihle kakhulu esizungezile: sibukhali ngokwanele ukusetshenziswa kochwepheshe, sibushelelezi ngokwanele emisebenzini yansuku zonke, futhi silula ngokwanele kuyo yonke imibukiso ye-USB namadivayisi. Ezimweni ezikhethekile (ukuhlola izimboni, ukusakaza, ukuhamba kancane), ukulungisa isici esisodwa ukuze kuqhakamshelwe isidingo sakho esiyinhloko kuzohlale kuletha imiphumela engcono kunokucindezela zombili emikhawulweni yazo. Ngokuzayo lapho ulungisa izilungiselelo zakho zekhamera ye-USB, yeka ukukhangisa okungenamsebenzi bese ugxila kulokho okubalulekile ngempela: ukufakwa okucacile, okubushelelayo okusebenzela injongo yakho ethile. Ngezinketho nezincomo zezilungiselelo kulo mhlahlandlela, awusoze uchitha izinsiza kuzici eziphakeme ezingadingekile futhi—uzothwebula ividiyo esezingeni lochwepheshe njalo lapho ucindezela irekhodi noma ujoyina ucingo lwevidiyo.
