Ngā Tikanga Tāutanga CCTV hei Whakaiti i ngā Wāhi Matapo
Ko te wāhi matapo he wāhi kāore e taupokina e te tirohanga a te kāmera CCTV. I roto i ngā pūnaha tirotiro, ko ngā wāhi matapo ngā ara e whakamahia whānuitia ana hei karo i te tirotiro - ahakoa i roto i ngā kāinga, i ngā toa, i ngā whare putunga, i ngā tari, i ngā wāhi tūmatanui rānei. Ko te raruraru, he maha ngā wā ka puta ngā wāhi matapo ehara i te mea nā te kounga iti o te kāmera, engari nā ngā tikanga tāutanga hē: ngā koki tāutanga hē, ngā teitei kāmera kāore i te tino pai, te tawhiti nui i waenga i ngā kāmera, te kōwhiringa arotahi hē rānei. Ka matapakihia e tēnei tuhinga ngā tikanga tāutanga CCTV whai hua hei whakaiti i ngā wāhi matapo, mai i te wāhanga whakamahere me te kōwhiringa taputapu tae noa ki ngā hua whakamātautau whakamutunga.
1. Kia mārama ki ngā take o ngā ira matapo i mua i te tāutanga
Ka puta ake ngā ira matapo i ngā herenga o te tirohanga whānui (FOV) o te kāmera, ngā arai ā-tinana, me ngā āhuatanga taiao. Hei tauira, ko ngā pou, ngā whata teitei, ngā rākau, ngā tuanui, ngā kokonga pakitara, ngā huringa teitei rānei (ngā arawhata me ngā arawhata). Ka ngaro pea ngā taipitopito o te mata i te kāmera e whakanohoia ana ki te teitei rawa, engari ka ngoikore te kāmera e whakanohoia ana ki te raro rawa, ā, ka hunaia e ētahi atu mea. Hei tāpiri, ka taea hoki e te mārama ngoikore te hanga i ngā ira matapo mahi: arā, ngā wāhi e hopukina ana e te kāmera, engari he pouri rawa, he whakamārama rānei ki muri, kāore e taea te pānui i ngā mea.
Ko te taahiraa tuatahi he mea nui ki te tirotiro i te wāhi. Haere i ngā ara noa (ngā tomokanga, ngā ara utu, ngā tatau o muri, ngā papa waka, ngā ara whare putunga), me te tuhi i ngā wāhi tino hira. Mai i reira, ka whakatauria te kapinga me te whiriwhiri i te momo kāmera e tika ana.
2. Whakatauhia te kaupapa o te tirotiro: te kimi, te mātakitaki, te tautuhi rānei.
Hei whakaiti i ngā wāhi matapo, me mārama koe ki te kaupapa o ia pūwāhi kāmera:
– Te Kitenga: e tino kitea ana te nekehanga/te aroaro o te tangata.
– Te mātakitaki: ka kitea mārama ake ngā mahi (hei tauira, ngā taunekeneke i te ara raro).
– Tuakiri: me mārama te mata, te pereti nama rānei.
Ka pā tēnei whāinga ki te tawhiti o te kāmera mai i te kaupapa, te kōwhiringa arotahi, te taumira, me te tūranga whakairinga. He hapa noa te whakawhirinaki ki tētahi kāmera whānui kotahi mō ngā kaupapa katoa. Ahakoa he nui te rohe e kapi ana i ngā kāmera whānui, he maha ngā wā ka tino whakaitihia ngā taipitopito tautuhi, ka waiho ngā "wāhi matapo": ehara i te mea kāore i tuhia, engari kāore e taea te whakamahi hei taunakitanga kaha.
3. Waihangahia he mahere papa me te mahere kapinga (whakatakotoranga e hangai ana ki te FOV)
Ko te tikanga haumaru rawa atu mō te whakaiti i ngā ira matapo ko te hoahoa i runga i te mahere papa. Whakamahia he tātuhi māmā: te tūranga o ngā tatau, ngā matapihi, ngā pou, te teitei o te whata, me te ahunga nekehanga. Kātahi, tuhia he "kone" o te tirohanga a te kāmera (FOV) mai i te pūwāhi whakairi.
Ngā mea hei mōhio:
– Taupoki i waenga i ngā kāmera: waiho kia 10–30% te taupoki i ngā wāhi nui, kia taea ai mēnā ka āraia tētahi kāmera, kei reira tonu ētahi atu kāmera e hopu ana.
– Kia tūpato ki ngā kokonga o te rūma: he maha ngā wā ka kitea ngā koki 90-tohu ina anga tika te kāmera, kāore he taupoki whakawhiti.
– Whakaritea ngā ara urunga ki te kaupapa matua: me iti rawa ngā wāhi matapo i ngā tomokanga, ngā tatau tauhokohoko, me ngā ara putanga.
Mō ngā wāhi uaua pēnei i ngā whare putunga, he mea āwhina te ariā o te "taupoki paparanga": he kāmera whānui mō te tirohanga whānui, me ētahi atu kāmera mō ngā taipitopito i ngā wāhi tino nui.
4. Kōwhiria te momo kāmera kia rite ki te āhua o te rohe
Ko te momo kāmera te mea nui hei whakatau i te wāhi matapo:
– Te tuanui/Te taupee: he pai mō te whakamahi i roto, he ngāwari te koki, he ātaahua te āhua, he uaua ki te whakatau i te ahunga o te arotahi.
– Matā: he pai mō te whakamahi i waho, he ngāwari ki te whai i te mata, he māmā ake te kitea, nō reira he pānga ārai.
– PTZ (Pan-Tilt-Zoom): ka taea te neke me te whakanui, engari kāore i te pai hei kāmera kotahi nā te mea ina anga te PTZ ki tētahi taha, ka noho ngā wāhi kē atu hei wāhi matapo. He pai ake te PTZ hei tāpiri.
– Kanohi Ika (360°): he pai mō te whakaiti i ngā wāhi matapo i ngā wāhi whānui (ngā whare tomokanga, ngā wāhi tuwhera) nā te mea ka hopukina he wāhi porowhita. Heoi, ka taea te whakapohehe i ngā taipitopito i ngā taha o te ahua, ā, ka whakawhirinaki tonu te tautuhi ki te taumira me te tawhiti.
– Pūoko maha: He maha ngā arotahi i roto i te waeine kotahi mō te whānuitanga o te kapinga me te kore he whanoke o te kanohi ika. He whai hua mō ngā kokonga whare, ngā wāhi waka rānei.
Ki te hiahia koe ki te tino hopu i te wāhi matapo, he pai ake te whakakotahi i te kāmera whānui me te kāmera arotahi (varifocal/tele) i te whakarārangi i ngā kāmera whānui.
5. Whakapai ake i te teitei o te tāutanga me te koki whakarara
Ngā ture matua e whakamahia whānuitia ana:
– I roto: He haumaru te tawhiti o te 2,5–3,5 mita, ā, kāore e taea te toro atu e te ringa, engari ka taea tonu te hopu i ngā taipitopito.
– Waho: 3–4 mita hei āwhina i te karo i te mahi tūkino, engari kia aro tonu ki ngā taipitopito o te kanohi me ngā pereti raihana.
He mea nui anō hoki te whakatītaha o te kāmera. Mēnā he koi rawa te whakatītaha o te kāmera, ka puta he wāhi matapo i raro tonu i te kāmera, ka puta rānei he wāhi tawhiti he iti, he uaua hoki ki te kite. I tetahi atu taha, mēnā he tino ōrite rawa te kāmera, ka puta he whakamārama rama mai i ngā rama, i te rā rānei, ka puta he pōuri ki ngā mea.
Ngā tikanga whai hua:
– Me anga paku te kāmera ki te taha hei tango i te koki o te mata, kaua ko te karauna anake.
– Kaua e whakairihia ki runga ake i te tatau e anga ana ki raro, kia poutū; he pai ake te whakairi i te taha o te tatau i te koki whakarara kia māmā ake ai te pānui.
6. Whakamahia te arotahi tika: kaua e "whānui" tonu
He maha ngā wāhi matapo ka puta mai i te kore tika o te whakaritenga o te arotahi. Ka hopukina e te arotahi whānui (hei tauira, 2,8 mm) he wāhi whānui, engari ka ngaro ngā taipitopito iti i ngā tawhiti waenga ki tawhiti. Mō ngā wāhi e hiahia ana kia tautuhia, whakamahia:
– Varifocal (hei tauira, 2,8–12 mm): he ngāwari ki te whakarerekē i te anga i te wā e tāuta ana.
– He arotahi whaiti (ātaata) mō ngā ara roa, te urunga tatau, ngā wāhi utu rānei.
He tikanga matua: te whakatau i te pūwāhi "tautuhi ūnga" (hei tauira, te tūranga o te tangata e tū ana i te tatau, i te kaiutuutu rānei), kātahi ka whakanuia, ka whakatakoto i te anga o te kāmera kia nui te wāhi o te whakaahua e whakakīia ana e te mata/pereti raihana. Mā tēnei ka whakakorea ngā wāhi matapo "mahi", ka hua ake he kiriata koretake.
7. Tāpirihia he hipoki whakawhiti ki ngā ara me ngā kokonga
Ko ngā ara raro, ngā ara whāiti, me ngā kokonga whare he pūtake matapōkere noa iho o ngā wāhi matapo. Ko te otinga:
– Tāutahia he kāmera ki te pito o te ara raro e anga ana ki te roa, me tētahi atu kāmera mai i te taha ke mēnā he roa, he nui rānei te mōrearea o te ara raro.
– Mō ngā koki o waho o te whare, whakamahia kia rua ngā kāmera e whakawhiti ana, kia kotahi rānei te kāmera maha-pūoko e wehewehe ana i te tirohanga ki ngā taha e rua.
– I ngā wāhi teitei o ngā whata hokohoko (ngā mākete iti/whare putunga), tāutahia he kāmera ki ngā ara hokohoko kia paku koki te koki kia kore ai ngā whata e huri hei "taiepa" e motu ana i te tirohanga.
Ehara te hipoki-whakawhiti i te tikanga he para; he huarahi tēnei kia kore ai e taea e tetahi mea te "tākaro" i te wāhi kāore e kitea.
8. Whakahaerehia ngā raruraru rama me te papamuri
Ehara i te mea ko ngā koki anake ngā wāhi matapo, engari ko te māramatanga anō hoki. Ka taea e ngā wāhi he tatau karāhe, he matapihi nui, he rama rānei te whakamārama i te tirohanga, ka āhua huna ai ngā mea.
Ngā tikanga hei whakakore i tēnei:
– Kōwhiria he kāmera me te WDR (Wide Dynamic Range) e pai ana mō ngā tomokanga me te mārama kaha mai i waho.
– Kia tino mohio kei te rawaka te hihi IR (infrared) mō te pō, engari kia aro ki te whakaata IR mai i ngā pakitara tata, i te karāhe rānei, ka kanapa ai.
– Kaua e anga tika atu ki ngā pūtake mārama (ngā rama waka, ngā rama pāka). Hurihia te koki, whakamahia rānei he tūnga teitei/whakaiti.
– Ki te mea e tika ana, tāpirihia he rama mā, he rama rānei mō te rohe kia kore ai te kāmera e "matapo" i te pō.
He iti ake te utu o te rama tika i te tāpiri kāmera, engari he nui tōna pānga ki te whakaiti i ngā ira matapo.
9. Kia aro ki ngā arai ā-tinana me ngā huringa pea o te whakamahere ā-wāhi.
Me whai whakaaro te tāutanga CCTV pai ki ngā panonitanga: te neke whata, te whakatipu rākau, te tāuta i ngā haki, te tūnga waka, te huri i ngā tatau, ngā whakapaipai ā-wā rānei. Hei whakaiti i ngā wāhi matapo nā ngā panonitanga:
– Whakatakotoria te kāmera ki tētahi wāhi teitei ake i ngā mea e arai ana (me te kore e whakaiti i ngā taipitopito).
– Kaua e tāpirihia kia tata rawa ki ngā pakitara ka taea te whakaata i te hihi IR.
– Waihangahia he rārangi arowhai tirotiro ā-wā: kei reira ētahi mea hou e taupoki ana i te kāmera, he karāhe paru, he koki kua nekehia rānei.
I roto i te hokohoko, he maha ngā whakarerekētanga tahora; whakaarohia te whānuitanga o te kapinga, ā, whakamaherehia ngā tūranga kāmera "ka ātete ki te whakarerekētanga".
10. Whakamātauria ngā hua tāutanga mā te whakatauira nekehanga
I muri i te tāutanga, whakahaerehia he whakamātautau e warewarehia ana: he tauira o te hikoi tangata i ngā ara rerekē. Me hikoi tetahi mai i te tomokanga, mā roto i tētahi wāhi motuhake, kātahi ki waho—tae atu ki roto i ngā kokonga kuiti me ngā wāhi ngoikore.
Tirohia:
– E kitea mārama ana te kanohi i te wāhi e tautuhia ai koe?
– He wāhi ngaro kei reira ina tata te tangata ki te kāmera (te rohe mate i raro i te kāmera)?
– He maeneene te hopu o te nekehanga, ā, kāore he pōuri nui?
– He kanapa IR kei te pō?
– He nui te taupatupatu i ngā wāhanga matua?
Ki te kitea e koe tētahi wāhi matapo, me whakarite he iti ngā whakarerekētanga i te tuatahi (te honga/te paninga, te teitei o te tauera, te whakanui rerekē-aroaro) i mua i te whakatau ki te tāpiri i tētahi kāmera.
11. Whakauruhia ki te whirihoranga pūnaha: taumira, tere moka, me te whakatakotoranga NVR
I ētahi wā ka puta ngā wāhi matapo nā te mea ka heke te kounga o te tuhi nā ngā tautuhinga hē. Kia tino mohio:
– He rawaka te taumira me te tere moka mō ngā take tautuhi.
– He rawaka te tere o te anga mō ngā wāhi tere (tomokanga, kaiutuutu).
– Te whakanoho pai o te NVR me te hanganga taura kia kore ai te kāmera e mate pinepine (ka puta he wāhi matapo katoa i te wā e kore ai e mahi).
Mō ngā kāmera IP, kia mau te whatunga me te mana PoE e ranea ana. Ahakoa te pai o te kapinga, ka taea e te korenga o te hiko, te kore rānei o te whatunga te whakakore i te kapinga pai.
Whakamutunga
Ko te whakaiti i ngā wāhi matapo i roto i te tāutanga CCTV ehara i te mea ko te tāpiri atu i ētahi atu kāmera anake; engari ko te whakakotahi i te whakamahere mahere papa, te whiriwhiri kāmera me te arotahi, te whakatikatika teitei me te koki, te hipoki whakawhiti, me te whakahaere rama. Ko te mea nui ko te mārama ki ngā ara nekehanga me ngā wāhi nui e tika ana kia tautuhia, te whakarite kia taupatupatuhia, me te whakahaere i ngā whakamātautau mara i muri i te tāutanga. Mā ngā tikanga tāutanga tika, kāore te CCTV e hopu noa i te ataata - ka tino noho hei pūnaha tirotiro whai hua, pumau, e rite ana hei whakamahi hei taunakitanga ina hiahiatia.
Ki te hiahia koe, ka taea e au te āwhina i a koe ki te waihanga i tētahi putanga motuhake mō tētahi wāhi (whare kotahi-papa, whare hokohoko, mākete iti, whare putunga, tari rānei) me ngā tauira o ngā wāhi tāutanga me te maha pai o ngā kāmera.
