Me pēhea te whiriwhiri i te taura pai rawa atu mō te tāutanga CCTV
I tēnei ao matatau haere o ēnei rā, kua noho te haumarutanga hei āhuatanga nui. Ko tētahi huarahi hei pupuri i te haumarutanga o ngā rawa ko te tāuta i ngā kāmera CCTV. Ka āwhina ngā kāmera CCTV (Pouaka Whakaata Porowhita Kati) ki te aroturuki me te tuhi i ngā aituā e puta ana i tētahi wāhi. Kia pai ai te mahi a te pūnaha CCTV, he mea nui te whiriwhiri i te taura tika. Ka whakamāramahia e tēnei tuhinga me pēhea te whiriwhiri i te taura pai rawa atu mō tō tāutanga CCTV, me te whakaaro ki ngā āhuatanga nui pērā i te momo taura, te kounga, me ngā whakaritenga pūnaha.
Ngā momo taura mō te CCTV
He maha ngā momo taura e whakamahia whānuitia ana i roto i ngā whakaurunga CCTV, he rerekē ngā painga me ngā ngoikoretanga o ia momo. Anei ētahi o ngā momo e tino kitea ana:
1. Taura Whakawhitiwhiti
Ko te taura coaxial tētahi o ngā mea rongonui mō ngā pūnaha CCTV tuku iho. E rua ngā momo matua o tēnei momo taura: RG59 me RG6.
– RG59: He pai rawa tēnei taura mō ngā tawhiti poto ki waenga, tata ki te 200-300 mita. He iti ake te matua parahi o te RG59, ā, he ngāwari ki te whakamahi i roto i te kāinga, i ngā whare iti rānei.
– RG6: He nui ake te pūtake parahi o tēnei taura, ā, he matotoru ake te whakamarumaru, he pai ake mō ngā tawhiti roa tae atu ki te 450 mita. Heoi, he pakari ake tēnei taura i te RG59, nō reira me nui ake te kaha i te wā tāutanga.
2. Taura Takirua Miro (Taura Takirua Miro)
Ko ngā taura takirua miro, pērā i ngā taura UTP (Unshielded Twisted Pair) Cat5e, Cat6 rānei, e whakamahia whānuitia ana i roto i ngā whatunga rorohiko engari ka taea hoki te whakatinana i roto i ngā pūnaha CCTV ma te whakamahi i ngā taura ataata.
– Kāwai 5e: Ka taea e tēnei taura te tuku raraunga tae atu ki te 100Mbps, ā, he pai hoki mō ngā tawhiti tae atu ki te 100 mita.
– Kāwai 6: He tere ake te tuku a tēnei taura, tae atu ki te 1Gbps, ā, ka taea hoki te whakamahi mō ngā tawhiti o te 100 mita engari he pai ake te kounga o te tohu.
3. Taura muka whatu
Mō ngā whakaurunga tawhiti (neke atu i te 500 mita), ko te taura muka whatu te whiringa tika. Ka whakamahia e tēnei taura ngā muka karāhe, ngā muka kirihou rānei hei tuku tohu mārama, ka taea ai te whakarato i te māramatanga me te pumau ake i ngā taura parahi. Ahakoa he utu nui ake, he uaua ake hoki te tāuta, he pai rawa te taura muka whatu mō ngā pūnaha CCTV nui pēnei i ngā taunga rererangi, ngā papa tākaro, ngā wāhi ahumahi rānei.
Kounga Taura
Ko te kounga o te taura te mea nui hei whakatau i te mahi a tō pūnaha CCTV. Ko ētahi āhuatanga hei whakaaroaro māu ina aromatawaihia te kounga o te taura:
1. Rauemi Arataki
He pai ake te mahi a ngā taura he parahi parakore ngā ara iahiko i ngā taura i hangaia ki te koranu konumohe, ki te whakakikoruatia rānei. He nui ake te ara iahiko o te parahi parakore, ā, he pumau ake te tuku raraunga, he iti ake hoki te pokanoa.
2. Paparanga Ārai
Mā te pai o te whakamarumaru ka tiakina ngā taura mai i ngā pokanoa o waho me ngā kino ā-tinana. Kōwhiria ngā taura he ātete ki te huarere me te mura mō ngā whakaurunga o waho.
3. Te whakamarumaru
Hei karo i te pokanoa hikohiko (EMI), he pai ake ngā taura he paparanga ārai whakarewa (whakamarumaru). Ka āwhina tēnei paparanga ki te pupuri i te kounga o te tohu, ā, ka ārai i te pokanoa mai i ētahi atu taputapu hiko tata.
Te Tātaitanga o te Roa me te Tawhiti o te Taura
He mea nui te mārama ki te tawhiti i waenga i te kāmera me te DVR/NVR (Kaituhi Ataata Mamati/Whatunga) hei whakatau ko tēhea taura hei whakamahi. Kia tika te ine i te tawhiti, ā, whiriwhiria he taura ka taea te whakahaere me te kore e tino ngaro te kounga o te tohu. Hei tauira, ki te neke atu i te 100 mita te tawhiti, ka tīmata koe ki te kite i te hekenga o te kounga me te taura Cat5e, nō reira me whakaaro pea koe ki te Cat6, ki te taura coaxial kounga teitei, ki te muka whatu rānei.
Ētahi atu Whakaaroaro
Haunga te momo me te kounga o te taura, he maha atu anō ngā āhuatanga hei whakaaroaro māu i te wā e whiriwhiri ana koe i te taura pai rawa atu mō te tāutanga CCTV, tae atu ki:
1. Momo Kāmera me te Hangarau
Mā te momo kāmera CCTV e whakamahia ana e koe (analog, digital, HD, IP rānei) ka taea te whakatau i te momo taura tino pai. He maha ngā wā ka pai ake ngā kāmera analog ki ngā taura coaxial, engari ko ngā kāmera IP he pai ake mō ngā taura takirua miro (Cat5e, Cat6 rānei).
2. Taiao Tāutanga
He pānga nui anō hoki tō te taiao e tāutahia ai te taura. Mena kei waho, kei tētahi wāhi rānei e tino pāngia ana e ngā āhuatanga taiao kino (wera, makariri, haumākū), me whiriwhiri he taura i hangaia kia tū atu ki aua āhuatanga.
3. Pūtea
Ka pā anō hoki te tahua ki te whiriwhiri taura. Ahakoa he maha ngā painga o ngā taura kounga teitei, pērā i te muka whatu, kāore pea te utu nui e tika mō ngā hiahia o te kaupapa. He mea nui kia kitea he taurite i waenga i te kounga me te tahua e wātea ana.
4. Hononga me te Hototahi
Me whakaaro anō hoki ki te hototahitanga o te taura ki te taputapu CCTV ka whakamahia e koe. Me whakarite kia ōrite ngā hononga e wātea ana ki ngā tauranga o te kāmera me te DVR/NVR. Hei tauira, ko ngā taura coaxial me whakamahi i ngā hononga BNC, ko ngā taura takirua miro ia e whakamahi ana i ngā hononga RJ45.
Whakamutunga
Ehara i te mahi ngāwari te whiriwhiri i te taura pai rawa atu mō te tāutanga CCTV. Me āta whakaaroaro kia pai ai te mahi a tō pūnaha CCTV, kia tino haumaru hoki. I te wā e whiriwhiri ana i te taura, me āta whakaaro ki te momo me te kounga o te taura, te tawhiti tāutanga, te momo kāmera, te taiao, te tahua, me te hototahitanga o ngā taputapu. Mā te whakamahere āta me te whiriwhiri tika, e kore e penapena moni anake, engari ka whakanuia hoki te mahi a tō pūnaha CCTV.
Kia maumahara he haumitanga roa te haumarutanga, ā, he wāhanga nui o taua haumitanga te kounga o te taura. Kaua e mangere ki te kōrero ki tētahi tohunga tāutanga CCTV, ki tētahi tohunga rānei mō ngā taunakitanga e hāngai ana ki ō hiahia. Mā te whiriwhiri i te taura tika, ka taea e koe te whakarite kia pai te mahi a tō pūnaha CCTV, kia pono hoki, kia whiwhi ai i te haumarutanga e hiahiatia ana e koe.
