Ngā karāhe CCTVe whakamahia whānuitia ana ināianei, engari kia taurite ai ki tētahi horopaki motuhake, me whai whakaaro ki ngā tawhā hangarau maha me ngā hiahia tono tuturu, pēnei i te tautuhi mārama i te ūnga aroturuki, te tawhiti aroturuki, me te taiao aroturuki.
I roto i tēnei tuhinga, ka tirohia taipitopitotia me pēhea te whiriwhiri i ngā karāhe CCTV e tika ana mō ngā āhuatanga motuhake.
Ko te whiriwhiri i tētahi karāhe CCTV e tika ana mō tētahi horopaki motuhake me whai whakaaro whānui ki ngā āhuatanga e whai ake nei:
1.Tautuhia ngā whakaritenga o te horopaki aroturuki
I mua i te whiriwhiri i tētahi karu tirotiro CCTV, he mea nui—hei taahiraa taketake—kia tautuhia tuatahitia ngā whakaritenga tirotiro motuhake mō te horopaki tono e whakaarohia ana. Tuatahi, me whakamārama i ngā āhuatanga o te ūnga aroturuki me te wāhi.
Hei tauira, whakaūtia mēnā he wāhi nui, he iti rānei te wāhi e tirohia ana e te ūnga, mēnā he poto, he roa rānei te tawhiti aroturuki, ā, mēnā kei roto, kei waho rānei te taiao aroturuki, me ngā āhuatanga mārama. Hei whakamutunga, me whiriwhiri te arotahi tika i runga i ēnei whakaritenga aroturuki motuhake.
2.Te whakataurite i ngā tawhā arotahi matua
Ko te roa o te arotahi, te whakatuwheratanga, te tirohanga whānui, me te taumira he mea nui ēnei hei whakaaroaro māu:
(1) Roa arotahi. He mea nui te roa arotahi hei whakatau i te whānuitanga tirohanga me te tawhiti aroturuki. He rerekē ngā roa arotahi e pā ana ki ngā āhuatanga aroturuki: ko te poto ake o te roa arotahi, ko te whānui ake o te whānuitanga tirohanga; i tetahi atu taha, ko te roa ake o te roa arotahi, ko te nui ake o te tawhiti tirotiro.
Hei tauira, he pai te roa arotahi 2.8mm mō te aroturuki i ngā tawhiti i roto i te 10 mita me te whānuitanga tirohanga tata ki te 100 nekehanga, he pai hoki mō te aroturuki i ngā rēhita moni o roto, ngā ararewa, me ētahi atu wāhi i roto i tētahi whānuitanga; he pai hoki te roa arotahi 8mm, neke atu rānei, mō te aroturuki i ngā tawhiti neke atu i te 15 mita, he pai hoki mō te aroturuki taipitopito tawhiti-roa i roto i ngā wāhi nui pēnei i ngā whare putunga me ngā papa waka.
He mea nui te roa o te arotahi hei whakaaroaro
(2) Pūaha. Mā te pūaha ka whakatau te nui o te mārama e tomo ana ki te kāmera, ka pā tika ki te pānga whakaahua i te pō. Mā te pūaha nui ake ka nui ake te mārama e tomo mai, ka mārama ake ngā whakaahua i ngā taiao iti te mārama, ā, ka pai mō ngā tirohanga tirotiro pō me te kore he rama tāpiri. He pai ake te pūaha iti ake mō ngā taiao mārama e hiahiatia ana te mārama whānui o te tirohanga—pērā i ngā raina whakaputa, i ngā whare putunga rānei.
I ngā wāhi o waho, i ētahi atu taiao rānei e tino rerekē ana te māramatanga o te taiao, he mea pai kia whiriwhiria hearotahihe āhuatanga iris-aunoa, ka taea te whakarite aunoa i runga i ngā āhuatanga o te mārama e huri haere ana.
(3) Te Papa Tirohanga. He hononga tata te papa tirohanga ki te roa o te arotahi, ā, ka whakatau tika i te whānuitanga ka taea e te arotahi te hipoki. I te nuinga o te wā, he nui ake te papa tirohanga o ngā arotahi whānui i te 90°, ā, he pai mō te tirotiro nui i ngā wāhi pēnei i ngā papa waka me ngā tapawhā tūmatanui; he iti iho i te 30° te papa tirohanga o ngā arotahi whakaahua-roa, ā, he pai mō te aroturuki taipitopito, tawhiti-roa—hei tauira, i roto i ngā tono e pā ana ki te mōhio ki ngā pereti raihana me te mōhio ki ngā kanohi.
(4) Taumira. Ka teitei ake te taumira o te arotahi, ka mārama ake te ahua. Heoi anō, me ōrite te taumira ki ngā whakaritenga taipitopito o te ūnga e aroturukitia ana. Ehara i te mea he pai ake te whai taumira teitei ake i ngā wā katoa.
I taua wā anō, me ōrite te taumira o te arotahi ki te taumira o te kāmera. Me hono ngā kāmera whakamārama-teitei ki ngā arotahi o te taumira e rite ana, ki te kore ka pōuriuri ngā taha o te ahua; ka hua ake hoki he moumou taumira ina honoa ngā arotahi whakataunga-teitei ki ngā kāmera whakataunga-iti.
Hei tauira, ka taea e te arotahi 2-megapixel te whakatutuki i ngā hiahia aroturuki taipitopito taketake, pērā i te kite i ngā āhua o te tangata me ngā whanonga whānui, ā, he pai hoki mō te aroturuki whānui i ngā ara raro me ngā whare putunga noa.
(5) Te whakairinga me ngā pūoko. Ko ngā whakairinga arotahi noa ko ngā whakairinga M12, C, me CS. I mua i te tāutanga, he mea nui kia whakarite kia ōrite te whakairinga arotahi ki te atanga o te kāmera; ki te kore e pērā, ka kore pea e taea te whakaputa i tētahi ahua mārama, ka pakaru rānei ngā taputapu.
E pā ana tēnei mātāpono ki te rahi o te pūoko: me ōrite te porowhita ahua o te arotahi ki ngā rahi o te pūoko o te kāmera; ki te kore, ka tino ngāwari te whakaahua ki te whakaahua ātaahua, ā, kāore e taea te hopu pikitia mārama.
He mea nui te taurite i ngā tawhā mō ngā arotahi CCTV
3.Teitei me te koki o te tāutanga
Te teitei me te koki o te tāutangaarotahiKa pāngia hoki ngā hua aroturuki e te kāmera. I te nuinga o te wā, ko te teitei o te whakairinga o te kāmera, ko te nui ake o tōna horahanga whakapae. Ina hopukina he tirohanga mai i te tirohanga ki raro mai i tētahi wāhi teitei, me whakanui ake te roa o te arotahi kia kore ai e moumou wāhi ki te tihi o te anga.
4.Ngā āheinga tirotiro i te pō
Mena e hiahiatia ana he tirotiro i te pō mō te horopaki tono, me whakaaro hoki ki tētahi arotahi e tautoko ana i te tirohanga pō infrared (IR) me te mahi tātari tapahi IR aunoa, kia mārama ai ngā whakaahua mō te aroturuki i te ao me te pō.
5.Te urutau me te pakari o te taiao
I te wā e whiriwhiri ana i ngā karāhe CCTV, he mea nui anō hoki kia whakaarohia te āheinga ki te urutau ki te taiao me te pakari—ina koa mō ngā karāhe e whakamahia ana mō waho. Me aro nui ki te āhua o ngā āhuatanga tiaki, pērā i te ātete ki te puehu me te wai, hei ārai i te urunga mai o te wai ua ka arahi pea ki te kino o te karāhe, ki te korenga rānei o te ahua.
Me whai whakaaro hoki te kōwhiringa o ngā karu CCTV ki te āheinga ki te urutau ki te taiao me te pakari.
6.Ngā kaupapa whiriwhiri mō ngā horopaki tono rerekē
(1) Te tirotiro ā-roto o te whare: I hangaia hei hipoki i ngā rūma katoa—pērā i te rūma noho—ko te kōwhiringa pai ko te tirotiro whānuiarotahime te roa arotahi o te 4mm me te whānuitanga tirohanga o te 70 nekehanga, e kore ai e hiahiatia he whakarerekētanga koki auau.
(2) Ngā tomokanga me te tirotiro i ngā ara: Ko te arotahi matua ko te aroturuki i ngā ara whaiti, ko te whāinga o tēnei whakatakotoranga he hopu mārama i te nekehanga o te tangata me ngā mea i te tawhiti waenga. E taunakihia ana kia whakamahia ngā karu arotahi he 2.8mm, he 4mm rānei te roa o te arotahi hei whakarite kia roa te hipoki. E taunakihia ana kia tāutahia kia 2.5 ki te 3 mita te teitei hei ārai i te koki nui ki raro, ka hua ake ai he aukati i te mata.
(3) Te tirotiro i te taha o te papa waka/whare putunga: Ko te whāinga matua kia kitea mārama ngā pereti nama me ngā āhuatanga o ngā kaimahi. Ka taea e koe te whiriwhiri i tētahi karāhe arotahi 8mm, neke atu rānei, hei tautuhi i ngā pereti nama me ngā tauira waka i te tawhiti o te 15-30 mita, kia kitea mārama ai hoki ngā mata. I te wā e tāuta ana ki waho, kia tino aro ki te taumata ātete-wai me te ātete-pūehu o te karāhe.
(4) Te tirotiro i te toa/te tirotiro tari: He āhua kati te wāhi, ā, he mea tika kia taurite te tirohanga me ngā taipitopito. Ko te arotahi matua ko te taiao whānui me ngā taipitopito. Ka taea te whiriwhiri i ngā karāhe 4mm, 6mm rānei. Mena e tika ana kia tuhia mārama ngā tukanga tauwhitinga, ngā āhuatanga kanohi rānei, ka tūtohutia he karāhe 6mm.
He rerekē ngā kōwhiringa mō ngā horopaki tono rerekē
(5) Te tirotiro i ngā wāhi whānui: I ngā wāhi whānui pēnei i ngā tapawhā, kāore e ranea te arotahi kotahi hei taupoki i ngā mōhiohio katoa. He mea tika kia whakamahia he huinga arotahi. Hei tauira, ka taea te whakamahi i te arotahi 2.8mm hei tiro i te tirohanga whānui, ka taea hoki te whakamahi i te arotahi 8mm hei tiro i ngā taipitopito o tētahi pūwāhi pumau. Ka taea te whiriwhiri i tētahi arotahi rerekē hei whakarerekē i te roa arotahi.
(6) Te tirotiro i ngā whakawhitinga waka: Ko ngā whakawhitinga waka pēnei i ngā huarahi tere me aroturuki i te tawhiti rawa atu kia kitea mārama ai ngā pereti nama me ngā mea e rau mita te tawhiti. Ka taea te whakauru i ngā pūnaha ki ngā karāhe whiriwhiri e whakaatu ana i ngā roa arotahi mai i te 30mm ki te 120mm; ina honoa ki ngā kāmera whakaahua wera infrared, ka whakarite kia whai hua te tirotiro ahakoa i ngā hāora pō, i raro rānei i ngā āhuatanga huarere kino.
I ngā āhuatanga rerekē, te arotahi pumau, tengā karaihe rerekēka taea te whiriwhiri kia rite ki ngā hiahia aroturuki motuhake. I te nuinga o te wā, he iti te utu, he pumau hoki ngā karāhe arotahi pumau, ā, he pai mō te aroturuki i ngā ūnga me ngā horopaki kei reira te tawhiti kua pumau; i tētahi atu ringa, he roa arotahi ka taea te whakarerekē, ā, he pai mō ngā horopaki kei reira te tawhiti aroturuki, te ūnga rānei me whakarerekē ngāwari.
