Amathiphu Ochwepheshe Okukhetha Ikhamera Yewebhu Engcono Kakhulu

Ukuthi ama-webcams manje ayingxenye ebalulekile yokuxhumana kwebhizinisi kuhamba ngaphandle kokungabaza. Amabhizinisi andayo, kungakhathaliseki ubukhulu bawo, amukela ukusebenza kude, futhi imihlangano ebonakalayo ithola ukuvelela okukhulayo. Ukuqonda izici ezihlukene zekhamera yewebhu kungakusiza wenze izinqumo ezingcono zokuthenga mayelana nokuthi iluphi uhlobo olungcono kakhulu ongaluthola.

Amakhamera ewebhu angaphandle ngokumelene namakhamera ewebhu angaphakathi

Igama elithi “webcam” manje selicishe lifane ne laptops, nakuba yayingakaze ibe njalo, futhi amakhamera ewebhu angaphandle asenezinzuzo zawo. Nakuba isilinganiso smartphone namuhla ilayishwe amakhamera athwebula izithombe namavidiyo anokulungiswa okuphezulu ngokwanele ukuze enze isithombe esihloniphekile phakathi nemihlangano ebonakalayo, ukuphela kwebhethri okusheshayo kuhlala kuwumkhawulo onzima. Lokhu-ke kwenza amalaptop abe yinketho ethembeke kakhulu ngezinjongo ezinjalo. 

Kodwa-ke, umbuzo owodwa osasele: "Ingabe ikhamera yewebhu esezingeni eliphansi ilungile ngokwanele?" Hhayi ngaso sonke isikhathi, ngesizathu esisodwa esilula: Ikhamera yewebhu yangaphakathi, njengekhamera yekhompuyutha ephathekayo eyakhelwe ngaphakathi, ingenye yezinto eziningi okufanele zibe nazo abakhiqizi bamalaptop abaphathekayo abazifaka emikhiqizweni yabo ngenkathi bezama ukuyigcina inenani elifanele. Kuyisenzo esinzima sokulinganisa futhi, ezikhathini eziningi, esibangela ukuba ikhwalithi yekhamera ihlupheke. 

Uma kuqhathaniswa nekhamera yewebhu ye-USB yangaphandle, ikhamera yewebhu yangaphakathi ngokuvamile ihlinzeka ngekhwalithi yesithombe empofu nokucaca kwezwi ngenxa yokusetshenziswa kwezingxenye zekhwalithi ephansi. Amakhompyutha aphathekayo nawo avamise ukuba nezinkinga zokushisisa, futhi amandla okuhlunga ukukhanya nokugxila ekhamera ngokuvamile aba sengozini, okwenza amakhamera ewebhu angaphakathi angafuneki kangako ngezinjongo zenkomfa yevidiyo. Ukuthuthukela kukhamera yewebhu yangaphandle kuza ngezindleko ezithe xaxa kodwa kuthembisa ikhwalithi engcono, izici, ukuqina, nolwazi lomsebenzisi. 

Izici ezibalulekile zekhamera yewebhu

Manje njengoba sesiqonda izinzuzo zokusebenzisa i- Ikhamera yewebhu ye-USB yangaphandle, ake singene kukho ukuthi yiziphi izici ezibalulekile okufanele sizibheke.

Resolution

Ukucaca kwesithombe nekhwalithi yevidiyo ngezinye zezinkomba ezisobala kakhulu zokusebenza kwekhamera. Ngakho-ke, kubalulekile ukuhlola ukulungiswa kwekhamera yewebhu. Izigaba ezintathu ezibanzi zokulungiswa phakathi kwamakhamera ewebhu angaphandle yilezi:

1280 x 720 pixels (HD Ready noma 720p): Lokhu kuvamise ukuba wukulungiswa okuphansi kakhulu phakathi kwamakhamera ewebhu anamuhla kodwa ahlala edumile ngezinjongo zokusakaza bukhoma kanye nenkomfa yevidiyo. 

1920 x 1080 amaphikseli (I-HD Egcwele noma 1080p): Le khamera yewebhu enokulungiswa okuphezulu iyinketho ekhethwayo yabasebenzisi bebhizinisi abafuna ukubukeka kwesikrini okubukeka njengochwepheshe.

3840 x 2160 pixels (Ultra HD noma 4K): Lawa makhamera ewebhu anokulungiswa okuphezulu ancanyelwa kakhulu ngezinjongo zokuhlela amavidiyo ekhwalithi ephezulu futhi eza nenani elikhuphukayo.

Ngakho, ezimweni eziningi, 720p futhi 1080p ama-webcams anele, kuye ngezidingo zomuntu kanye nesabelomali.

Ukukalwa kwe fulemu

Okunye okubizwa ngokuthi amafreyimu ngomzuzwana (i-fps), izinga lozimele liphinde libe yisici esibalulekile sokunquma ukusebenza kwekhamera yewebhu njengoba libonisa ukuthi ividiyo izoba bushelelezi kangakanani. Kusukela ku-30fps ephansi futhi ikhuphuke ifike ku-120fps, amakhamera ewebhu aphezulu futhi athengekayo avame ukuza nama-60fps anesinqumo esingu-720p noma ama-30fps anesinqumo esingu-1080p.

Ikhamera yekhamera 

Kunezinto ezimbili ezibalulekile okufanele zicatshangelwe mayelana nelensi yekhamera yewebhu: ukwakheka kwayo kanye nomkhakha wayo wokubuka. Amalensi ekhamera yewebhu afika ngezinhlobo zengilazi nezepulasitiki. Naphezu kwephuzu lentengo eliphakeme, kuwukuhlakanipha ukukhetha eyangaphambili njengoba ingilazi ilula ukunwaya, ngaleyo ndlela inikeze ukucaca okungcono nokuqina.

Inkambu yokubuka (i-FOV) ikhombisa ububanzi bendawo ethathwe ilensi yekhamera yewebhu futhi isukela kumadigri angu-60, ithwebula umuntu oyedwa, iye ku-90 degrees, ithumba iqembu labantu. Ukukhetha kwakho kuzoncika ekutheni ikhamera yewebhu idingelani. 

I-microphone eyakhelwe ngaphakathi

Esinye isici esibalulekile kodwa esivame ukushaywa indiva ikhamera yewebhu imakrofoni eyakhelwe ngaphakathi, evumela ukuzizwisa kwenkomfa ngevidiyo engahlangani. Amanye ama-webcams akhona imibhobho emibili eyakhelwe ngaphakathi (noma ama-omnidirectional) asiza ukuthwebula umsindo wemvelo kakhudlwana. Nakuba amamakrofoni angaphandle enekhwalithi yomsindo ephakeme kakhulu, ukuthuthukisa ubuchwepheshe bemakrofoni eyakhelwe ngaphakathi kumakhamera ewebhu kuyawasiza ukuthi athole ukuduma okukhulu phakathi kwabasebenzisi.

Izici ezengeziwe ezizuzisayo zekhamera yewebhu

Izici zekhamera yewebhu ezingabalulekile azisho ukuthi kufanele zinganakwa. Nazi ezimbalwa ezifanele ukukhulunywa ngazo ngokukhethekile.    

Ukugxila okuzenzakalelayo nokulungiswa kokukhanya okuphansi

Ikhwalithi yesithombe esifiphele ingase iphazamise futhi ikhungathekise ngesikhathi sokusebenzisa ikhamera yewebhu. I isici se-autofocus ngakho-ke iza kahle njengoba igxilisa ngokuzenzakalelayo ikhamera esihlokweni esikhundleni sengemuva. Amakhamera ewebhu athuthuke kakhulu anenzuzo eyengeziwe yokugxila okuzenzakalelayo okusheshayo, ngisho nasezindaweni ezimatasa kakhulu.

Kodwa-ke, ngisho ne-auto-focus ingahluleka ezimeni ezingakhanyiswe kahle, njengasekuseni kakhulu nasebusuku. Ukukhetha ikhamera yewebhu enesici sokulungisa ukukhanya okuphansi kuxazulula le nkinga, kuthuthukisa ukusebenza kwe-autofocus kuzo zonke izimo zokukhanya. Amanye amamodeli ekhamera yewebhu ephezulu ayatholakala namalambu akhangi akhelwe ngaphakathi, avumela umsebenzisi ukuthi alungise izinga lokukhanya.

Ukuhlolwa okuluhlaza

Kungase kube nezizathu ezimbalwa zokuthi kungani umsebenzisi angase afune ukufiphalisa ingemuva lakhe phakathi nekholi yevidiyo - kusukela ekufihleni ingemuva eligcwele imfuhlumfuhlu kuya ekuvikeleni ubumfihlo bomuntu. Ukuhlola okuluhlaza kuyisici esikhethekile esitholakala ngamanye amakhamera ewebhu okuthi, ngaphandle kokufiphalisa, futhi angashintsha ingemuva lesihloko ngokuthanda kwabo.

Ukusekelwa kwe-Software

Noma ubani osebenzisa ikhamera yewebhu ecebile angazuza ekusekelweni kwesofthiwe. Ngokusebenzisa izilawuli zesofthiwe, umsebenzisi angasetha izintandokazi zakhe zesici ngasinye, ngaleyo ndlela abanikeze ukulawula okukhulu ekusebenzeni kwabo okufisayo kwekhamera yewebhu.

Isifinyezo

Kafushane, ukuthenga ikhamera yewebhu yangaphandle kuwukutshalwa kwezimali okuhlakaniphile kwamabhizinisi noma lawo asemigqeni esemthethweni yomsebenzi. Ukugxila ezicini ezihlobene nesithombe, ividiyo, nekhwalithi yomsindo kungasiza umthengi ukuthi athole izisekelo ezifanele, kuyilapho ukuqonda izici ezengeziwe zekhamera yewebhu kungasiza abasebenzisi ukuthi bathole okuningi kubuchwepheshe babo.

Njengoba umhlaba uqhubeka nokuncipha ngokwedijithali, isidingo sokugcina ukumelwa okungokoqobo ngezikrini siya ngokuya sibaluleke kakhulu. Ukuthenga ikhamera yewebhu evumelana kangcono nezidingo zebhizinisi lomuntu kanye nesitayela kuwutshalomali olufanele futhi olushibhile olungase lukhokhe ngokuhamba kwesikhathi. I esigcawini namuhla igcwele amakhamera ewebhu angapheli, ngakho ukujwayelana nezici kungakusiza wenze ukukhetha okulungile ngokushesha.Hlala unolwazi lwamathrendi akamuva futhi uthole ulwazi olwengeziwe lwemboni, imininingwane yochwepheshe, kanye nezindaba ezifika ngesikhathi ze-B2B ku- U-Chovm Uyafunda.
