Hangarau Whakaahua Wera i roto i ngā Kāmera CCTV
Kāore te whanaketanga o ngā pūnaha haumarutanga hou e whakawhirinaki ana ki ngā kāmera CCTV tuku iho e whakawhirinaki ana ki te mārama e kitea ana. I roto i ngā momo rāngai - mai i te ahumahi me ngā hanganga nui ki te haumarutanga ā-rohe - me "kite" pono i roto i ngā āhuatanga mārama kino, i te rangi kino, i te wā rānei e ngana ana ngā mea ki te huna. Koinei te wāhi e piki haere ana te rongonui o te hangarau whakaahua wera i roto i ngā kāmera CCTV. Ka mahi ngā kāmera wera mā te hopu i te hihi wera (whero) e tukuna ana e ngā mea, ka taea ai e rātou te kite i te aroaro o te tangata, o ngā waka, o ētahi atu pūtake wera rānei, me te kore e whakawhirinaki ki te mārama.
He aha te Whakaahua Wera?
Ko te whakaahua wera he hangarau e whakaputa ana i ngā whakaahua i runga i ngā rerekētanga pāmahana o tētahi rohe. Ka tukuna e ngā mea katoa he pāmahana kei runga ake i te kore tino. Ka hopukina e ngā kāmera wera tēnei pūngao ka hurihia hei whakaahua (whakaahua wera), e whakaatuhia ana i te nuinga o te wā i roto i te tae, i te pango me te mā rānei. Ko ngā wāhi wera ka puta he kanapa ake, he tae motuhake rānei (hei tauira, mā/kōwhai/whero), ko ngā wāhi mātao ia ka puta he pōuri ake, he tae rerekē rānei (hei tauira, kikorangi/papura/pōuri), i runga i te papatae tae e whakamahia ana.
He rerekē tēnei i ngā kāmera CCTV tuku iho, e hiahia ana ki te mārama mai i ngā rama, i te rā, i ngā rama whakamārama whero rānei (IR LED) hei tiro i te pōuri, kāore ngā kāmera wera e hiahia ki ētahi atu rama. He painga nui tēnei mō te tirotiro i te pō, i ngā wāhi tūroa, i ngā wāhi whānui rānei pērā i ngā rohe wheketere, ngā tauranga, ngā taunga rererangi, me ngā māra ahuwhenua.
Te Mahi a ngā Kāmera CCTV Wera
He māmā noa iho, he mea hanga te kāmera wera ki tētahi karāhe motuhake (he mea hanga ki te germanium) me tētahi pūoko wera (pūoko wera). Ko te pūoko tino noa ko te microbolometer, e ine ana i ngā huringa o te ātete nā te wera i whiwhi mai i te irahiko infrared. Kātahi ka tukatukahia te pūngao wera i hopukina hei tohu matihiko, kātahi ka maherehia hei whakaahua wera.
He mea nui kia mārama: ka kitea e ngā kāmera wera te wera o te mata, ehara i te mea ka "kite mā roto" i ngā pakitara, e ai ki te maha o ngā wā e hē ana te mārama. Ka taea e tēnei hangarau te uru ki te kohu mārama, ki te pōuri rānei, engari kāore i hangaia hei uru ki ngā rauemi totoka pērā i ngā pakitara, ngā tatau, ētahi momo karāhe rānei. Inaa, he maha ngā wā ka whakaatahia e te karāhe noa te hihi whero-whero, ka kore ai e tika ngā kitenga o ngā mea kei muri i te karāhe.
Te rerekētanga i waenga i te CCTV Wera me te CCTV Tirohanga Pō (IR)
He maha ngā wā ka whakapoauau te tangata i ngā kāmera wera me ngā kāmera tirohanga pō whero-whero. Heoi, he rerekē ēnei:
1. CCTV IR (Tirohanga Pō)
– E whakawhirinaki ana ki ngā rama IR LED hei whakamārama i te rohe.
– Ka noho tonu te ahua i runga i te whakaata o te mārama (ahakoa kāore e kitea e te kanohi tangata).
– Tērā pea ka heke te mahi i te aroaro o te kohu matotoru, te ua nui, ngā mea pouri rānei e mimiti ana i te mārama.
2. CCTV Wera
– Te whakawhirinaki ki te wera e puta mai ana i ngā mea.
– Kāore e hiahiatia he rama.
– Kaha ake mō te kite i te tangata/waka i roto i te pōuri, te kanapa, te iti rānei o te rerekētanga tirohanga.
Arā, he pai ngā kāmera IR mō te tautuhi tirohanga, pērā i ngā taipitopito kanohi, kākahu rānei, mai i te tawhiti tata. He tino pai ngā kāmera wera ki te kimi me te whai i ngā mea i roto i ngā āhuatanga uaua, inā koa i ngā wāhi whānui.
Ngā Painga o te Hangarau Whakaahua Wera mō te Haumarutanga
1. Te Kite Pono i te Pōuri Katoa
Nā te mea kāore e pāngia e te mārama, ka taea e ngā kāmera wera te mahi ahakoa i te pō me te kore he rama. Ka āwhina tēnei ki te whakaiti i ngā utu rama, ā, ka whakaitihia hoki ngā wāhi matapo e puta mai ana i te motuhanga hiko, i te whakarerekētanga rānei.
2. Mahi Pai i roto i ētahi Āhuatanga o te Huarere
Ka taea e te kohu, te paoa, te puehu, te rama whakamārama rānei (te mārama e puta mai ana i te taha kē, pērā i ngā rama o ngā waka) te whakararuraru i ngā kāmera tuku iho. He maha ngā wā ka taea tonu e te whakaahua wera te kite i ngā atarangi wera o te tangata, o ngā mīhini rānei i roto i ēnei āhuatanga, ahakoa ka pāngia te kounga o te whakaahua e te haumākū me te pāmahana o te taiao.
3. Te Kimi Āpitihanga Whai Hua Ake
Mō te tiaki i ngā taiapa, ngā rohe, ngā wāhi tomo turekore rānei, ka whakamahia ngā kāmera wera me ngā tātaritanga pērā i te kimi urutomo, te waea toronga, me ngā taiapa mariko. Nā te mea he teitei ake te pāmahana o te tangata i tō rātou taiao, ka taea e te pūnaha te wehewehe ngāwari i ngā ūnga mai i te papamuri.
4. Whakaitihia ngā Whakaoho Hē
Mā te CCTV tuku iho, ka puta he whakaoho teka i ngā atarangi, i ngā rama rama, i ngā panonitanga rama rānei. He pumau ake te ahua o te whakaahua wera nā te mea he puhoi ake ngā panonitanga wera i ngā panonitanga rama. Mā te whirihoranga tātari tika, ka taea te whakaiti i ngā whakaoho teka.
5. Te Tautoko i te Haumaru me te Whakaiti i te Mōrearea
Haunga te haumarutanga, ka taea te whakamahi i ngā kāmera wera hei kite i ngā wāhi wera i roto i ngā panera hiko, i ngā mīhini wera rawa, i te kite wawe rānei i ngā ahi pea i roto i ngā wāhi rokiroki rauemi motuhake. Nā tēnei, ehara i te mea he pai anake te haumi ki ngā kāmera wera mō te haumarutanga engari mō te haumaru hoki.
Ngā Here hei Mārama
Ahakoa ōna painga, ehara ngā kāmera wera i te otinga mō ngā hiahia katoa.
1. Ngā Taipitopito Tautuhinga Iti rawa
Kāore te whakaahua wera e hopu pai i ngā taipitopito pēnei i ngā kanohi, ngā pereti nama, ngā tae rānei o ngā kākahu. Nō reira, he maha ngā wā ka honoa ngā kāmera wera ki ngā kāmera e kitea ana hei pūnaha pūoko rua.
2. Ngā Utu Teitei Ake
Ko te tikanga he nui ake te utu o ngā kāmera wera i ngā CCTV noa, inā koa ko ērā he teitei te taumira wera, he nui ngā karāhe arotahi, he matatau rānei ngā āhuatanga tātari.
3. Ngā Wero i ngā Pāmahana Taiao Rite
Mena he tata te pāmahana o te mea ki te pāmahana o te taiao (hei tauira, he rā wera me te mata wera), ka heke pea te rerekētanga o te wera, ka uaua ake te kite.
4. Te Pānga o te Ua Nui me te Makuku
Ka taea e te ua nui me te haumākū nui te ngoikore o te tuku hihi infrared i ngā tawhiti roa, nō reira ka taea te whakaiti i te tawhiti kitea whai hua.
