Njengoba sazi, ohlelweni lwe-CCTV, ikhamera ye-IP iyisisetshenziswa esiphambili esibaluleke kakhulu, ikakhulukazi ikhamera ye-AI, ikhamera ye-PTZ.Kungakhathaliseki ukuthi iyiphi ikhamera ye-IP, idome/inhlamvu/i-PTZ, ngisho nekhamera yasekhaya ehlakaniphile, kufanele sibe nombono ovamile wezingxenye zawo ngaphakathi.U-Elzoneta uzokwembulela impendulo kulesi sihloko njengoba ngezansi.
1.Ukwakheka kweukugadwaikhamera:
Iqukethe ikakhulukazi izingxenye ezine ezinkulu kanye nezingxenye ezintathu ezincane.
Izingxenye ezine ezinkulu: i-chip yekhamera, ilensi, iphaneli yesibani, indlu.
Izingxenye ezintathu ezincane: ikhebula lomsila, i-lens mount, insika yethusi, njll.
Kungani amakhamera emikhiqizo ehlukene enephikseli efanayo, kodwa amanani ahlukene?Iphuzu eliyinhloko yikhwalithi yezinto ze-hardware nesisombululo sesofthiwe esisetshenziswa kulezi zingxenye.
2. IkhameraI-chip:
Ingxenye ebaluleke kakhulu yekhamera yenethiwekhi yi-chip, ubuchopho bekhamera.I-chip ishumekwe ebhodini lomama;izingxenye ezimbili ezibalulekile zebhodi lomama inzwa yesithombe: I-CCD noma i-CMOS, kanye ne-chip processor.
Lapha, kufanele sifunde umehluko phakathi kwe-CCD ne-CMOS.
Ngenqubo yokukhiqiza, i-CMOS ilula kune-CCD.
Ngezindleko, i-CMOS ishibhile kune-CCD.
Ekudleni kwamandla, ukusetshenziswa kwe-CMOS kunamandla amancane kune-CCD.
Ngomsindo, i-CMOS inomsindo owengeziwe kune-CCD.
Ngokuzwela okukhanyayo, i-CMOS ayizwela kakhulu kune-CCD.
Ukuze kulungiswe, i-CMOS inokulungiswa okuphansi kune-CCD.
Nakuba i-CCD iphakeme kune-CMOS ngekhwalithi yesithombe, i-CMOS inenzuzo yezindleko eziphansi, ukusetshenziswa kwamandla okuphansi nokunikezwa okuzinzile, isiphenduke intandokazi yabakhiqizi bedivayisi ye-CCTV.Ngakho-ke, ubuchwepheshe bokukhiqiza be-CMOS buthuthukiswa njalo futhi buvuselelwa, okwenza umehluko ube mncane kancane kancane.
3. Ilensi yeqaphaikhamera
Ulwazi olubalulekile mayelana ne-Len yekhamera yokuqapha ubude bendawo nokuvuleka.
Ubude bokugxila: Yileyo ndlela amamilimitha ama-lens amangaki esivame ukuwasebenzisa.Ngokuvamile 4mm, 6mm, 8mm, 12mm nokunye.
Uma inani lamamilimitha lilikhulu, ububanzi obuncane kanye nebanga elikude lens elizolibamba.Isibonelo, ukuqapha i-workshop kanye ne-warehouse, ngokuvamile isebenzisa i-lens engu-4 mm;emnyango omkhulu wesakhiwo sokuhlala, ngokuvamile isebenzisa u-6 mm;odongeni nasendleleni, ngokuvamile isebenzisa 12 mm.Yiqiniso, i-lens kufanele ikhethwe ngokuguquguqukayo ngokuya ngohlelo oluthile.
Imbobo: Yinombolo ka-F ekwilensi, ngokuvamile ethi F1.0, F1.2, F1.4, F1.6.
Uma i-F-number encane injalo, i-flux ekhanyayo iba, futhi i-lens ibiza kakhulu.
4. Isibani sekhameraiphaneli
Amaphaneli okukhanya kwekhamera avamile ahlanganisa: Isibani se-Array IR, ukukhanya okujwayelekile kwe-IR, ukukhanya okumhlophe/okufudumele.
Inhloso yephaneli yokukhanya ukuhlinzeka ngokukhanya okuyisizayo kwelensi ebusuku.Ngokukhanya kwe-IR, le lensi ingakwazi ukuzwa futhi ibambe ukukhanya kwe-infrared ikwenze isithombe.Ukukhanya okumhlophe/okufudumele kuvame ukuhlanganiswa ne-super starlight kanye nemojuli yokukhanya okumnyama, okusiza ukubamba ukubona okumibalabala ebusuku.
5. Izindlu zekhamera
Indawo yekhamera iza ngezinhlobonhlobo zomumo, ngokuvamile amamodeli ezinhlamvu, idome, eyindilinga.Izinto zokwakha zezindlu ziyi-aluminium kanye nepulasitiki ngokuvamile, efika ku-IP66/IP67 engangeni manzi.
Yilokho odinga ukukwazi mayelana nesakhiwo sonke sekhamera.Ikhamera ye-IP ye-ELZONETA isebenzisa ama-chips nezinsiza zekhwalithi ephezulu, ithatha ukulungisa iphutha mathupha kwelensi ngayinye nokumataniswa kwengxenye yombala, futhi yenza amahora angu-24 okubona ukuguga.Kungakho ikhamera ye-Elzoneta isengagcina ukusebenza kahle ngemuva kweminyaka engu-4-5 evamile ukusetshenziswa.
