Amalensi e-CCTV, okungukuthi, amalensi ekhamera ye-CCTV, anezimo eziningi zokusetshenziswa namuhla. Kungashiwo ukuthi amakhamera e-CCTV ayadingeka noma kuphi lapho kunabantu nezinto.
Ngaphezu kokuba ithuluzi lokuphatha ezokuphepha, amakhamera e-CCTV asetshenziswa nasekuvimbeleni ubugebengu, ekuphenduleni eziphuthumayo, ekuqapheni imvelo nakwezinye izinhlelo zokusebenza, futhi indima yawo ayinakubukelwa phansi.
1.Wenza njaniI-CCTVamalensi ayasebenza?
Ngamalensi e-CCTV, singabheka indlela esebenza ngayo:
(1)Ukuthwebula izithombe
Ikhamera ye-CCTV ithwebula izithombe zendawo eqondiwe ngezinzwa zezithombe bese iziguqula zibe izimpawu zikagesi.
(2)Icubungula izithombe
Isignali yesithombe idluliselwa kuphrosesa yesithombe yangaphakathi, bese yenza ukulungiswa kokuchayeka okuzenzakalelayo, ukulungiswa kwebhalansi emhlophe, ukuhlunga umsindo kanye neminye imisebenzi yokuthuthukisa ikhwalithi yesithombe.
Ilensi ye-CCTV evamile
(3)Ukudluliswa kwedatha
Idatha yesithombe esicutshunguliwe idluliselwa kudivayisi yokugcina noma ohlelweni lokuqapha ngokusebenzisa isikhombimsebenzisi sokudlulisa idatha (njengenethiwekhi noma umugqa wedatha). Ukudluliswa kwedatha kungaba ngesikhathi sangempela noma kungabi ngesikhathi sangempela.
(4)Ukugcinwa kwedatha nokuphathwa kwayo
Idatha yesithombe igcinwa ku-hard drive yesistimu yokuqapha, isitoreji samafu, noma eminye imithombo yezindaba ukuze idlalwe, ilandwe, futhi ihlaziywe ngokulandelayo. Uhlelo lokuqapha luvame ukunikeza isikhombikubona esibonakalayo sabasebenzisi ukuze baphathe futhi bafinyelele idatha egciniwe.
Ilensi ye-CCTV endaweni yokusebenza
2.Imibuzo eminingana evamile mayelanaI-CCTVamalensi
(1)Indlela yokukhetha ubude be-focal yeI-CCTVilensi?
Uma ukhetha ubude obuqondile belensi ye-CCTV, ngokuvamile landela lezi zimiso ezilandelayo:
①Kala ukukhethwa kobude obuqondile ngokusekelwe kusayizi kanye nebanga lento eqashwe.
②Ngokuya ngezinga lemininingwane ofuna ukuyibona into: uma ufuna ukubona imininingwane yento eqashwe, udinga ukukhetha ilensi enobude obude bokugxila; uma udinga ukubona isimo esijwayelekile kuphela, khetha ilensi enobude obufushane bokugxila.
③Cabanga ngemikhawulo yesikhala sokufaka: Uma isikhala sokufaka selensi sincane, ubude bokugxila akufanele bube bude kakhulu, ngaphandle kwalokho isithombe sizoba sincane kakhulu.
Amalensi e-CCTV ahlukahlukene
(2) Kungcono yini uma ububanzi be-focal lens ye-CCTV bukhulu?
Ukukhetha ubude obuqondile beIlensi ye-CCTVkudinga ukunqunywa ngokwezidingo zangempela zokuqapha. Ngokuvamile, ilensi enobude obude obugxile ingamboza ibanga elide, kodwa futhi kusho ukuthi i-engeli yokubuka yesithombe incane; kuyilapho ilensi enobude obufushane obugxile ine-engeli yokubuka ebanzi, kodwa ayikwazi ukubona imininingwane ekude.
Ngakho-ke, lapho ukhetha ubude be-focal lens, kubalulekile ukukhetha ngokuya ngendawo yokuqapha yangempela kanye nemigomo okufanele ifinyelelwe. Akuyona ngempela indaba yokuthi uma ububanzi be-focal bubukhulu, kungcono.
(3) Yini okufanele uyenze uma ilensi ye-CCTV ingacacile?
Uma ilensi ye-CCTV itholakala ingacacile, kunezixazululo eziningana ezingaba khona:
①Lungisa ukugxila
Isithombe singase singacaci ngenxa yokugxila okungafanele kwelensi. Ukulungisa ukugxila kungenza isithombe sicace.
②Hlanza ilensi
Ilensi ingase ifiphale ngenxa yothuli noma ezinye izinto. Ngalesi sikhathi, sebenzisa amathuluzi okuhlanza afanele ukuhlanza ilensi.
③Ciswishi ye-artifact
Uma ilensi isafiphele, ungahlola inkinobho yokwenziwa yelensi ukuze ubone ukuthi ivuliwe yini.
④Shintsha ilensi
Uma lezi zindlela ezingenhla zingakwazi ukulungisa inkinga, kungenzeka ukuthi ilensi iyaguga noma yonakele, futhi ilensi entsha idinga ukushintshwa.
Amaqembu amakhamera e-CCTV avamile
(4) Yini ebangela ilensi ye-CCTV engacacile?
Izizathu eziyinhloko zokungacaciAmalensi e-CCTVkungaba: ukungcola ebusweni belensi, ukuminyana komhwamuko wamanzi, ukudlidliza noma umthelela belensi okubangela izinkinga zokugxila, ukufiphala ngaphakathi kwezinkinga zekhamera noma zemojuli, njll.
(5) Ungasusa kanjani uthuli kulensi ye-CCTV?
① Ungasebenzisa umshini wokufutha noma amanye amathuluzi afanayo ukuze uphephule uthuli ebusweni belensi.
②Ungasebenzisa iphepha lokuhlanza ilensi elisezingeni eliphezulu noma indwangu ekhethekile yokuhlanza ilensi ukuze uhlanze ilensi.
③Ungasebenzisa futhi uketshezi lokuhlanza ilensi olukhethekile ukuze uhlanze, kodwa khumbula ukulandela indlela enqunyiwe ukuze ugweme ukulimaza ilensi.
Imicabango Yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
