Amamitha e-electromagnetic field (EMF), asetshenziswa kumakhamera ashisayo ukuthola izindawo ezingabonakali zikagesi, ayingxenye ebalulekile ekukhiqizeni izinto zikagesi kanye ne-IT kanye nethuluzi eliyigugu phakathi kwabaphathi bezikhungo nosonkontileka be-HVAC.
Kusukela ekusizeni ngokulawula ikhwalithi emigqeni yokukhiqiza kuya ekuhlolweni kwamandla ezinqolobaneni, lawa madivayisi angaphezulu nje kwemishini yobuchwepheshe obuphezulu—awutshalo-mali oluhlakaniphile olunganciphisa izindleko futhi luqondise ukusebenza.
Kulesi sihloko, sizongena kulokho okufanele ukubheke kukhamera eshisayo efanelekile futhi siveze izimo ezithile zokusetshenziswa.

Ukulungiswa kanye nekhwalithi yesithombe
Njengamakhamera amaningi nezikrini, uma amaphikseli engeziwe, isithombe sizocaca. Kucabange njengokuthuthuka kusuka ekulungisweni okujwayelekile kuya ku-HD TV.
Kochwepheshe kulo mkhakha, sincoma ukuthi uqale ngokulungiswa okungenani kwamaphikseli angu-640×480. Lokhu kunikeza isisekelo esihle sezithombe ezinemininingwane ezishisayo. Ukuze uthwebule ngisho nokuhlukahluka kwezinga lokushisa elicolekileyo namaphethini okushisa, cabanga ukwenyukela ku-1024×768 noma ngaphezulu.
Ibanga lokuzwela
Umehluko wokushisa olingana nomsindo, noma i-NETD, iyindlela enhle yokusho ukuthi ikhamera inhle kangakanani ekuboneni umehluko omncane wezinga lokushisa.
Ukuzwela okushisayo kukalwa nge-millikelvin (mK), futhi uma inombolo iphansi, ikhamera iba ngcono nakakhulu ekuboneni lokhu kuguquguquka.
Kucabange njengomdlalo “wokushisa nokubanda”—ikhamera ezwelayo engu-50 mK ifana nengcweti, ekutshela uma ufudumala ngisho noma usanda kunyakaza. Lo mqondo onamandla ubalulekile emisebenzini efana nokuthola izinkinga zikagesi ezikhohlisayo noma ukukhomba lapho kunezinkinga khona kumaskeni wezokwelapha. Uma uphansi inombolo, kungcono, kodwa uma ufuna ukusebenza okubucayi, bheka amakhamera ano-50 mK noma ngaphansi.
Vuselela rate
Izinga lokuvuselela likalwa nge-Hertz (Hz) futhi libonisa ukuthi isithombe sekhamera sibuyekezwa ngokushesha kangakanani - uma inombolo iphezulu, ividiyo iba bushelelezi. Uma kungenzeka ukuthi ufuna ukulandelela ukunyakaza okusheshayo noma udinga impendulo yesikhathi sangempela, hlose u-30 Hz noma ngaphezulu.
Izinketho zokubonisa
Bheka amakhamera anezikrini ezikhanyayo, ezipholile ongazifunda ngisho nalapho kuphume ilanga. Izikrini zokuthinta ziyibhonasi enhle uma uthanda isenzo sokuncinza nokusondeza. Uma ufuna ukwabelana nomhlaba ngezinto ozitholile ezishisayo (noma okungenani ithimba lakho), hlola izinketho zokuxhumanisa ikhamera enazo nokuthi ingaxhunywa ezikrinini ezinkulu yini.
impilo yebhethri
Ayikho into embi njengokuphuma kwekhamera yakho lapho nje izinto kushisa. Uzofuna okungenani amahora angu-4-6 wejusi kulawo maseshini okuhlola ama-marathon. Amabhethri ashintshekayo ayisindisi sempilo, futhi izindlela zokonga amandla zingaba isiteleka sangempela sebhethri.
Ukuqina kanye nokumelana nesimo sezulu
Masibhekane nakho: amakhamera ashisayo awakona nje ukusetshenziswa ehhovisi elithokomele. Badinga ukuqina emhlabeni wangempela. Bheka amakhamera angakwazi ukuwa futhi aqhubeke nokusebenza. Isilinganiso se-IP se-IP54 noma ngaphezulu sisho ukuthi ikhamera yakho ngeke iphonse ithawula lapho kuphawulwa khona uthuli noma ukuconsa.
Ukuqonda izici zobuchwepheshe zamakhamera ashisayo
Uhlobo lomtshina kanye nobuchwepheshe
Manje, ake sikhulume ngobuchopho bekhamera – umtshina. Yinduku yomlingo eshintsha ukushisa okungabonakali kube izithombe ezibonakalayo. Kunezinhlobo ezimbili eziyinhloko: ama-microbolometer angapholisiwe kanye nezitholi ezipholile.
Ama-microbolometer angapholisiwe afana ne-sedan yomndeni ethembekile - ethengekayo, eqinile, futhi eyilungele imisebenzi eminingi. Izitholi ezipholile, ngakolunye uhlangothi, zizwela kakhulu futhi zikunikeza izithombe ezicace njengekristalu, kodwa ziza nenani eliphakeme futhi zidinga ukupholisa ukuze zisebenze.
Inkambu yokubukwa
Cabanga ngenkundla yokubuka (i-FOV) njengokubona kwekhamera yakho. I-FOV ebanzi ifana nokuba namehlo ngemuva kwekhanda lakho - ilungele ukuskena izindawo ezinkulu ngokushesha. Kodwa-ke, uma udinga ukusondeza imininingwane njalo, njengokuhlola intambo ethile kuphaneli kagesi exutshwe, uzofuna i-FOV encane.
Izici ezisebenziseka kalula
Isixhumi esibonakalayo nezilawuli
Okokuqala, i-interface kanye nezilawuli. Ufuna okuthile okulula ukukusebenzisa, ngisho noma ugqoke amagilavu noma usebenza ezindaweni ezimpintshana. Bheka amakhamera anezikrini ezinkulu, ezicacile ezikubonisa yonke imininingwane oyidingayo. Izikrini zokuthinta zinhle kakhulu njengoba zikuvumela ukuthi uswayiphe futhi uthephe njenge-smartphone yakho. Amanye amamodeli aphambili akuvumela ukuthi wenze ngokwezifiso izinkinobho.
Izinketho zokuxhuma
Kulezi zinsuku, amakhamera ashisayo ahlakanipha njengamafoni ethu. Abaningi bane-Wi-Fi ne-Bluetooth ukuze ukwazi ukulayisha izithombe zakho ngqo ocingweni noma kukhompuyutha ephathekayo. Kodwa uma ungekho entweni engenantambo, ungayithukutheli. Amakhamera amaningi asenazo izimbobo ze-USB nezikhala zekhadi le-SD. Okokugcina, uma udinga ukukhombisa okutholile esikrinini esikhulu, bheka ikhamera enokuphuma kwe-HDMI.
Ukuhambisana kwesoftware
Yilapho umlingo wenzeka khona ngemva kokuthatha izithombe zakho ezishisayo. Amakhamera amaningi eza nesofthiwe yawo, engenza izinto ezinhle kakhulu njengokuhlaziya okuningiliziwe nokubika.
Kepha nali ithiphu lochwepheshe: Bheka ukuthi ikhamera isebenza yini nenye isoftware, nayo. Kungenzeka ukuthi usunalo uhlelo oluthandayo lokuhlela isithombe noma ukubhala umbiko. Kubuhlungu ukufunda isofthiwe entsha ngenxa nje yokuthi ikhamera yakho iyakufuna.
Isifinyezo
Ngobubanzi bezinketho nezici ezikhona, ukukhetha ikhamera eshisayo ephathwayo efanelekile kungaba nzima. Ngokuvamile, uzofuna imodeli eyenza umsebenzi wenziwe ngaphandle kokukunika ikhanda enkambisweni.
Izinto ezifana nokuzwela kwe-thermal (ukuthi kuhle kangakanani ekuboneni umehluko omncane wezinga lokushisa), uhlobo lomtshina (ubuchopho bekhamera, ngokuyisisekelo), indawo yokubuka (ukubona okungakanani), nezindlela zokugxilisa kuzo kufanele zibe phezulu ohlwini lwakho lokuhlola.
Ukuze uthole uhla olukhulu lwamakhamera ashisayo avela kubahlinzeki abathembekile, qiniseka ukuthi uhlola izinketho Cooig.com.
