Maunga M12
Ko te maunga M12 e pā ana ki tētahi maunga arotahi paerewa e whakamahia whānuitia ana i roto i te ao whakaahua mamati. He maunga āhua iti tēnei e whakamahia nuitia ana i roto i ngā kāmera kiato, ngā kāmera tukutuku, me ētahi atu taputapu hiko iti e hiahia ana kia taea te whakawhiti arotahi.
Ko te tawhiti arotahi o te pūmau M12 he 12mm, koinei te tawhiti i waenga i te pūmau (te mowhiti whakarewa e hono ana i te arotahi ki te kāmera) me te pūoko whakaahua. Mā tēnei tawhiti poto ka taea te whakamahi i ngā arotahi iti, māmā hoki, ā, he pai mō ngā pūnaha kāmera kiato, kia kawe hoki.
Ko te hononga miro te tikanga o te whakairinga M12 hei whakau i te arotahi ki te tinana o te kāmera. Ka whaowhia te arotahi ki te kāmera, ā, mā ngā miro ka mau te hononga, ka pumau hoki. E mōhiotia ana tēnei momo whakairinga mō tōna māmā me te ngāwari ki te whakamahi.
Ko tētahi painga o te whakairinga M12 ko tōna hototahitanga whānui ki ngā momo karāhe arotahi. He maha ngā kaihanga karāhe arotahi e whakaputa ana i ngā karāhe arotahi M12, e tuku ana i te whānuitanga o ngā roa arotahi me ngā kōwhiringa whakatuwheratanga hei whakatutuki i ngā hiahia whakaahua rerekē. Ko ēnei karāhe arotahi he mea hanga noa hei whakamahi me ngā pūoko whakaahua iti e kitea ana i roto i ngā kāmera kiato, ngā pūnaha tirotiro, me ētahi atu taputapu.
Maunga C
Ko te maunga C he maunga arotahi paerewa e whakamahia ana i roto i te mara o ngā kāmera ataata me te kiriata ngaio. I whakawhanakehia tuatahitia e Bell & Howell i te tekau tau atu i 1930 mō ngā kāmera kiriata 16mm, ā, i muri mai ka whakamahia e ētahi atu kaihanga.
Ko te tawhiti arotahi o te pūmau C he 17.526mm, koinei te tawhiti i waenga i te pūmau me te pūoko whakaahua, te papa kiriata rānei. Mā tēnei tawhiti poto ka taea te ngāwari te hoahoa arotahi, ā, ka hototahi ki te whānuitanga o ngā arotahi, tae atu ki ngā arotahi matua me ngā arotahi whakanui.
Ka whakamahia e te maunga C he hononga miro hei tāpiri i te karāhe ki te tinana o te kāmera. Ka whakawirihia te karāhe ki te kāmera, ā, mā ngā miro ka mau te hononga. Ko te whānui o te maunga he 1-inihi (25.4mm), he iti noa iho i ērā atu maunga karāhe e whakamahia ana i roto i ngā pūnaha kāmera nui ake.
Ko tētahi o ngā painga matua o te C mount ko tōna whānui o ngā mahi. Ka taea te whakauru i ngā momo arotahi maha, tae atu ki ngā arotahi kiriata 16mm, ngā arotahi hōputu 1-inihi, me ngā arotahi iti ake i hangaia mō ngā kāmera kiato. Hei tāpiri, mā te whakamahi i ngā urutau, ka taea te whakairi i ngā arotahi C mount ki runga i ētahi atu pūnaha kāmera, ka whakawhānui ake i te whānuitanga o ngā arotahi e wātea ana.
Kua whānuitia te whakamahinga o te C mount mō ngā kāmera kiriata i mua, ā, kei te whakamahia tonutia i roto i ngā kāmera matihiko o ēnei rā, inā koa i roto i ngā mara whakaahua ahumahi me te pūtaiao. Heoi, i ngā tau tata nei, kua nui haere te whakamahinga o ētahi atu mount arotahi pērā i te PL mount me te EF mount i roto i ngā kāmera kiriata ngaio nā te mea ka taea e rātou te whakahaere i ngā pūoko nui ake me ngā arotahi taumaha ake.
I te nuinga o te wā, he mea nui tonu te maunga C hei maunga arotahi, he maha hoki ngā whakamahinga, inā koa i ngā whakamahinga e hiahiatia ana te kiato me te ngāwari.
Maunga CS
Ko te maunga CS he maunga arotahi paerewa e whakamahia whānuitia ana i roto i te mara o ngā kāmera tirotiro me te haumarutanga. He toronga tēnei o te maunga C, ā, he mea hanga motuhake mō ngā kāmera he iti ake ngā pūoko whakaahua.
He rite tonu te tawhiti arotahi o te pūmau CS ki te pūmau C, arā, 17.526mm. Ko te tikanga ka taea te whakamahi i ngā karāhe pūmau CS ki ngā kāmera pūmau C mā te whakamahi i tētahi urutau pūmau C-CS, engari kāore e taea te tāuta tika i ngā karāhe pūmau C ki ngā kāmera pūmau CS me te kore he urutau nā te poto ake o te tawhiti arotahi o te pūmau CS.
He iti ake te tawhiti arotahi o muri o te maunga CS i te maunga C, e āhei ai te nui ake o te wāhi i waenga i te arotahi me te pūoko whakaahua. E tika ana tēnei wāhi tāpiri hei whakauru i ngā pūoko whakaahua iti e whakamahia ana i roto i ngā kāmera tirotiro. Mā te neke atu i te arotahi mai i te pūoko, ka arotauhia ngā arotahi o te maunga CS mō ēnei pūoko iti, ā, ka whakaratohia te roa arotahi me te kapinga e tika ana.
Ka whakamahia e te maunga CS he hononga miro, he rite ki te maunga C, hei whakapiri i te arotahi ki te tinana o te kāmera. Heoi, he iti ake te diameter miro o te maunga CS i tō te maunga C, arā, 1/2 inihi (12.5mm). Ko tēnei rahi iti ake tētahi atu āhuatanga e wehewehe ana i te maunga CS mai i te maunga C.
He whānui te wātea o ngā karaihe whakapuru CS, ā, he mea hanga motuhake mō ngā mahi tirotiro me te haumarutanga. He maha ngā roa arotahi me ngā kōwhiringa karaihe e tukuna ana e rātou hei whakatutuki i ngā hiahia tirotiro rerekē, tae atu ki ngā karaihe whānui-koki, ngā karaihe tawhiti-whakaahua, me ngā karaihe rerekē-arotahi. Ko ēnei karaihe e whakamahia ana i roto i ngā pūnaha pouaka whakaata porowhita-katia (CCTV), ngā kāmera tirotiro ataata, me ētahi atu mahi haumarutanga.
He mea nui kia mōhio koe, kāore ngā karāhe whakairinga CS e hototahi tika ki ngā kāmera whakairinga C me te kore he urutau. Heoi, ka taea te huri i te āhua, ina taea te whakamahi i ngā karāhe whakairinga C ki ngā kāmera whakairinga CS me te urutau tika.
