Noma ngabe ufaka ikhamera eyodwa ye-USB ukuze kuvikeleke indawo yokuhlala noma iqoqo eligcwele lamakhamera ombono wezithombe zezimboni, izimiso eziyinhloko kulo mhlahlandlela ziyasebenza yonke indawo: phambili ukudluliswa kahle kokushisa, ukuhlinzeka ngamandla azinzile, ukwenza kahle abashayeli ne-firmware, nokuvikela i-hardware ezinkingeni zemvelo. Ngalezi zinyathelo eziqondisiwe, amakhamera akho e-USB azosebenza ngokuthembekile nangokungaguquki, noma ngabe asebenza isikhathi esingakanani.
Imibuzo Evame Ukubuzwa: Ukuqiniseka Kokusebenza Kwesikhathi Eside kwe-USB Camera
Umbuzo 1: I-USB camera ingasebenza isikhathi esingakanani ngokuqhubekayo ngokwenziwa ngcono okufanele?
Nge-thermal, amandla, kanye nokwenza kahle kwe-software okuphelele, ikhamera ye-USB esezingeni eliphezulu ingasebenza ngokuqhubekayo izinyanga eziyi-12+ ngaphandle kwezinkinga ezinkulu. Amamodeli asezingeni labathengi angadinga ukulungiswa okuncane (njengokuhlanza uthuli) njalo ezinyangeni eziyisi-6, kanti amakhamera asezingeni lezimboni angasebenza ngokungagadiwe iminyaka eminingana.
Umbuzo 2: Kungani ikhamera yami ye-USB ikhumuka kuphela ngemuva kokusebenzisa isikhathi eside, hhayi ngokushesha ngemuva kokuyilungisa?
Lolu daba cishe njalo lubangelwa ukwehla kancane kwe-thermal throttling noma ukwehla kwamandla okwenzeka kancane kancane. I-heat iqoqana kancane ngokuhamba kwesikhathi, ilimaze izingxenye zangaphakathi, noma ukushintshashintsha kwamandla kuyanda njengoba izintambo namachweba eguga ngesikhathi sokusebenzisa isikhathi eside ngokuqhubekayo.
Umbuzo 3: Ngingasebenzisa imbobo ye-USB 2.0 yokusakaza ikhamera isikhathi eside?
Amachweba e-USB 2.0 awanawo amandla adingekayo namandla okulethwa ukuze kube nokusakazwa okuzinzile kwe-1080p noma i-4K, okuholela ekulahlekelweni okuncane kwezithombe nokunqamuka ekugcineni ngokuhamba kwesikhathi. Njalo sebenzisa amachweba e-USB 3.0/3.1 ukuze usebenze njalo kwamakhamera esikhathi eside.
Umbuzo 4: Ngidinga isofthiwe ekhethekile ukuze ngisakaze ikhamera ye-USB isikhathi eside?
Isoftware yokusakaza enesisindo esilula, enikezelwe (njenge-AMCap ye-Windows noma i-Motion ye-Linux) ilungele ukusetshenziswa kwesikhathi eside, njengoba inciphisa umthwalo wezinsiza zesistimu futhi inciphisa ubungozi bokuvuza kwenkumbulo. Iziqhumane zokululama ngokuzenzakalelayo nazo zinconywa kakhulu ukuthunyelwa okungagadiwe ngokuphelele.
