Ngā painga o te CCTV me ngā āhuatanga pan-tilt-zoom (PTZ)
I ngā tau tata nei, kua piki ake te hiahia mō ngā pūnaha haumarutanga pono, ahakoa mō ngā kāinga, ngā tari, ngā toa hokohoko, ngā whare putunga, ngā wāhi tūmatanui, ngā whare ahumahi rānei. Ko tētahi otinga e whiriwhiria whānuitia ana nā tōna ngāwari me ōna āheinga ko te CCTV me ngā āhuatanga pan-tilt-zoom (PTZ). Kāore i rite ki ngā kāmera CCTV tūmau e aroturuki ana i te taha kotahi me te koki tirohanga pumau, ka taea e ngā kāmera PTZ te neke whakapae i te kāmera (pan), poutū (tilt), me te whakanui i te ahua (zoom) kia kite i ētahi taipitopito. Mā te whakakotahitanga o ēnei mahi e toru ka pai ake te PTZ ki te aroturuki i ngā wāhi whānui me ngā āhuatanga hihiri.
E matapakihia ana e tēnei tuhinga ngā painga maha o te PTZ CCTV, ngā take e whakawhirinaki ai te nuinga o ngā whakahaere ki tēnei PTZ CCTV, me ngā mea nui hei whakaaroarohia i mua i te kōwhiri me te tāuta.
1. He whānui ake te horapa mā te whakamahi i te taputapu kotahi
Ko te painga nui o te PTZ CCTV ko tōna kaha ki te kapi i tētahi wāhi whānui atu i tētahi kāmera tūmau. Mā te nekehanga pan (maui-matau) me te nekehanga titaha (runga-iho), ka taea e te kāmera te kapi i ngā koki maha i te wāhi kotahi. He tino whai hua tēnei mō ngā wāhi pēnei i:
– te marae me te karāti,
– te tomokanga whare me te wāhi waka,
– he whare putunga me ngā ara maha,
– te rohe whakaputa wheketere,
– ngā whakawhitinga huarahi, ngā kēti, me ngā pou haumaru.
I ētahi wā, ka taea e te kāmera PTZ kotahi te whakakapi i ngā kāmera pūmau maha e hiahiatia ana hei aroturuki i ngā wāhi maha. Ka hua ake tēnei i te tirotiro pai ake, me te whakahaere pai ake, ka whakaiti i te maha o ngā pūwāhi kāmera.
2. Te āheinga whakanui hei hopu i ngā kōrero nui
He painga te āhuatanga whakanui i runga i ngā kāmera PTZ ina hiahia ngā kaiwhakamahi ki ngā whakaahua taipitopito o ngā mea tawhiti. Hei tauira, ka hiahia pea ngā āpiha haumarutanga ki te kite:
– te kanohi o tētahi i te wāhi waka,
– ngā pereti nama waka i te tomokanga,
– ngā mahi whakapae i te kokonga o te rūma,
– te āhua o ētahi taonga, mīhini rānei.
Mā te whakanui whatu (i runga i te maha o ngā tauira PTZ), ka taea te whakatutuki i te whakanui me te kore e tino ngaro te kounga o te ahua, he rerekē ki te whakanui mamati, e whakangaro ana i ngā taipitopito. Koia te take e whakamahia pinepine ai te PTZ i ngā wāhi e tika ana te tautuhi tika i ngā mea.
3. Te aroturuki hihiri me te urupare tere ki ngā kaupapa
Ki ngā kāmera pūmau, ina puta ngā mahi i waho o te tirohanga a te kāmera, kāore pea e whai pānga ngā kiriata, kāore rānei e hopu i te whānuitanga katoa o te mahi. Mā ngā kāmera PTZ ka taea e te kaiwhakahaere te tohu tika i te kāmera ki te pūtake o te aituā. I ngā āhuatanga ohorere—pēnei i te tangata tauhou, te raruraru, te mahi whakapae rānei—ka taea e te kaiwhakahaere te:
1. tohua te kāmera ki te wāhi,
2. whakanuia ngā mea hei tautuhi,
3. whai i ngā nekehanga o te ūnga i te wā tonu.
He mea nui tēnei urupare tere hei whakaiti i te mōrearea, hei kohikohi taunakitanga, hei āwhina hoki i te tukanga whakahaere i ngā aituā.
4. Āhuatanga tirotiro aunoa whai hua
He maha ngā kāmera PTZ he āhuatanga kua whakaritea me ngā āhuatanga tirotiro-aunoa. Mā ngā tautuhinga kua whakaritea ka taea e ngā kaiwhakamahi te tiaki i ngā tūranga kāmera motuhake—hei tauira, "keti o mua," "keti uta," "kaiutuutu," "taiapa o muri rānei." Kia oti te hanga i tētahi tautuhinga kua whakaritea, ka taea e te kāmera te neke aunoa i runga i te raupapa tirotiro kua whakaritea.
Ko ngā painga o te tirotiro aunoa ko:
– ka taea e te kāmera te "haereere" me te aroturuki i ētahi wāhi me te kore he kaiwhakahaere,
– te aroturukitanga auau ake i ngā hāora nui (pō, kati rānei te toa),
– ka whakaiti i te whakawhirinaki ki ngā mana whakahaere ā-ringa.
He tino whai hua tēnei āhuatanga mō ngā wāhi nui e hiahia ana kia aroturukitia auau, kia kore ai te kāmera e "noho" noa i te kokonga kotahi.
5. Aroturuki aunoa i runga i ētahi tauira
Ka tukuna e ngā tauira PTZ matatau ake te aroturuki aunoa e ahu mai ana i te tātari ataata. Ka taea e te kāmera te kite i ngā mea e neke ana (pēnei i te tangata, i ngā waka rānei) kātahi ka whai aunoa i ā rātou nekehanga, tae atu ki te whakarerekē i te huri, te whakatītaha, me te whakanui.
Ko ngā painga o te aroturuki aunoa ko:
– ka āwhina i te aroturuki me te kore e nui te wawaotanga a te kaiwhakahaere,
– te whakanui ake i ngā tūponotanga o te whiwhi i ngā rekoata e tika ana,
– hei āwhina i te aroturuki i te nekehanga o te ūnga mai i te tīmatanga ki te mutunga o te aituā.
He tino pai tēnei āhuatanga mō ngā wāhi pēnei i ngā wāhi waka, ngā marae nui, ngā taha o ngā whare, ngā wāhi rānei e nui ana te mahi a ngā waka.
6. Te whai huatanga o te utu i roto i ētahi āhuatanga
Ahakoa he nui ake te utu o ngā kāmera PTZ i ngā kāmera tūmau, ka taea e ngā PTZ te whakaiti i te utu i roto i ētahi āhuatanga, inā koa:
– he whānui te wāhi e aro turukihia ana, ā, he maha ngā koki e hiahiatia ana,
– ka nui ake te utu mō te tāuta i ngā kāmera pūmau maha (tae atu ki ngā taura, ngā tauranga NVR, me ngā utu tāutanga),
– e hiahiatia ana ngā āheinga tautuhi tawhiti e uaua ana ki te whakatutuki me ngā kāmera tūmau.
Hei tauira, he nui ngā kāmera e hiahiatia ana hei taupoki i ngā koki katoa i tētahi papa waka nui. I taua wā, ka taea e tētahi, e rua rānei ngā kāmera PTZ kua whakanohoia ki ngā wāhi rautaki te whakawhānui ake i te taupoki me te whakarato i ngā āheinga whakanui ina hiahiatia.
7. He ngāwari te whakauru ki ngā pūnaha haumarutanga hou
Ko ngā kāmera PTZ o ēnei rā he mea hototahi ki ngā momo pūnaha haumarutanga maha, pēnei i:
– NVR me VMS (Pūnaha Whakahaere Ataata),
– taupānga pūkoro mō te mana mamao,
– ngā pūnaha whakaoho me ngā pūoko nekehanga,
– te mana uru mō te tukutahitanga o ngā huihuinga,
– Ngā tātaritanga AI pērā i te kimi tangata/waka, te whiti rārangi, me te kimi urutomo.
Mā tēnei whakaurunga ka āwhina i te hanga i tētahi pūnaha haumarutanga atamai ake, ehara i te mea ko te tuhi noa iho, engari ko te whakarato hoki i ngā whakatūpato mōata me te whakahaere i ngā tirotirohanga.
8. He pai mō te tirotiro i waho me te roa o te mau
He maha ngā kāmera PTZ kua hangaia mō te whakamahinga o waho me ngā paerewa ātete huarere pēnei i te IP66/IP67, ā, kei roto ko te hangarau infrared (IR) me te hangarau mārama iti mō te tirohanga pō. I ngā wāhi o waho, he tino whai hua ngā kāmera PTZ nā te mea ka taea e ngā aituā te puta mai i tawhiti atu i te tirohanga a te kāmera, engari me whai mōhiohio taipitopito tonu ngā kaiwhakahaere.
He āhuatanga tāpiri anō hoki kei ētahi tauira pēnei i:
– te horoi matapihi mō te ua/te puehu,
– he whakamahana mō ngā pāmahana tino kino,
– te ārai i te uira me te ngaru hiko.
Mā ēnei āhuatanga ka pai ake te whakarite o te PTZ ki te aro atu ki ngā āhuatanga taiao wero.
9. Tautoko i te whakahaere haumarutanga e hangai ana ki te kaiwhakahaere
He tino pai ngā kāmera PTZ ina aro turukihia ana te aroturuki e te āpiha haumarutanga. Mā te whakamahi i te mana whakahaere rakau, i tētahi taupānga rānei, ka taea e te kaiwhakahaere te arahi i te kāmera ki ngā wāhi tino nui. Nā tēnei ka pai ngā kāmera PTZ mō:
- te pou haumaru,
– te rūma whakahaere haumarutanga,
– te pokapū aroturuki whare,
– te aroturuki i ngā huihuinga, i ngā mano tini rānei.
I ētahi wā, he nui ake te whai huatanga o te kaha o te kaiwhakahaere ki te whakatau i te arotahi o te tirotiro i tētahi kāmera tūmau e hopu ana i tētahi wāhi pumau anake.
10. Ngāwari o te rautaki whakanoho me te tirotiro
He tino whai hua ngā kāmera PTZ ina tāutahia ki ngā wāhi rautaki, pērā i te teitei me te tirohanga whānui. Mā tēnei ka taea e ngā kāmera te:
– matawai i te taha,
– te aroturuki i te urunga mai me te urunga atu,
– arotahi ki ngā wāhi ngoikore i ētahi wā.
Mā tēnei ngāwari ka āwhina i ngā kaiwhakamahi ki te hoahoa i ngā rautaki haumarutanga urutau. Hei tauira, i ngā hāora pakihi, ka arotahi ngā kāmera ki te wāhi ratonga kiritaki, i te pō, ka neke rātou ki te tatau o muri me te wāhi rokiroki.
Ngā Whakaaro i mua i te Kōwhiri i te PTZ CCTV
Hei tino rongo i ngā painga o te PTZ, he maha ngā mea me aro atu koe ki:
1. Ngā hiahia tirotiro: Me aroturuki whānuitia, me tautuhi mamao, me whai taonga rānei?
2. Te whakanui whatu me te taumira: Ka nui ake te whakanui whatu me te teitei ake o te taumira, ka pai ake te taipitopito ka riro mai.
3. Ngā āhuatanga rama: Me whakarite kei te tautokohia te IR, te mārama iti, te WDR rānei mō ngā wāhi tino rerekē.
4. Te tere o te nekehanga me te pumau: Ka taea e te PTZ pai te huri tere engari ka noho pumau tonu i te wā e whakanui ana.
5. Te whānui o te arai me te rokiroki: Me nui te kaha whatunga me te kaha rokiroki mō te ataata taumira teitei.
6. Te tiaki tinana me te haumaru: Me tiaki ngā PTZ o waho mai i te mahi kino me te huarere.
Whakamutunga
He nui ngā painga o te CCTV me ngā āheinga pan-tilt-zoom (PTZ) mō te rohe kapi, te kaha ki te hopu taipitopito mā te zoom, te aroturuki hihiri, me ngā āhuatanga aunoa pēnei i te tirotiro me te whai. He pai te PTZ mō ngā wāhi nui, ngā wāhi mahi nui, me ngā pūnaha haumarutanga e hiahia ana ki te urupare tere me te tirotiro hohonu.
Mā te whiriwhiri tika i ngā taputapu me te tāutanga rautaki, ka taea e te PTZ CCTV te noho hei haumitanga haumarutanga whai hua—ehara i te mea mō te hopu i ngā huihuinga anake, engari mō te āwhina hoki ki te ārai i ngā aituā me te tere ake te urupare ina puta ngā āhuatanga morearea.
