Zigawo za kamera yowunikira

Monga tikudziwira, mu dongosolo la CCTV, IP kamera ndi chipangizo chofunika kwambiri kutsogolo, makamaka kamera ya AI, kamera ya PTZ.Ziribe kanthu kuti IP kamera, dome/chipolopolo/PTZ, ngakhale kamera yanzeru yakunyumba, tiyenera kukhala ndi lingaliro lazigawo zake mkati.Elzoneta ikuwulula yankho lanu m'nkhaniyi monga pansipa.

1.Mapangidwe akuyang'anirakamera:

Amakhala makamaka ndi zigawo zinayi zazikulu ndi zitatu zazing'ono.

Zigawo zinayi zazikulu: chip kamera, mandala, gulu la nyali, nyumba.

Zigawo zitatu zazing'ono: chingwe cha mchira, phiri la lens, mzati wamkuwa, ndi zina zotero.

Chifukwa chiyani makamera osiyanasiyana ali ndi pixel yofanana, koma mitengo yosiyana?Mfundo yaikulu ndi khalidwe la hardware zipangizo ndi mapulogalamu njira ntchito mbali zimenezi.

2. KameraChip:

Gawo lofunika kwambiri la kamera ya network ndi chip, ubongo wa kamera.Chipcho chimayikidwa mu bolodi;mbali ziwiri zofunika za bolodi ndi sensa chithunzi: CCD kapena CMOS, ndi chip purosesa.

Apa, tiphunzire kusiyana pakati pa CCD ndi CMOS.

Pakupanga, CMOS ndi yosavuta kuposa CCD.

Pa mtengo, CMOS ndi yotsika mtengo kuposa CCD.

Pakugwiritsa ntchito mphamvu, CMOS imagwiritsa ntchito mphamvu zochepa kuposa CCD.

Pa phokoso, CMOS ili ndi phokoso kwambiri kuposa CCD.

Pakuzindikira kopepuka, CMOS ndiyosavuta kuposa CCD.

Pakukonza, CMOS ili ndi malingaliro otsika kuposa CCD.

Ngakhale CCD ndi apamwamba kuposa CMOS mu khalidwe lachifaniziro, CMOS ali ndi ubwino wa mtengo wotsika, otsika mphamvu yogwiritsira ntchito mphamvu ndi kugawira kokhazikika, wakhala wokondedwa wa opanga zipangizo za CCTV.Chifukwa chake, ukadaulo wopanga CMOS umasinthidwa ndikusinthidwa, zomwe zimapangitsa kusiyana pang'onopang'ono.

3. Diso lakuyang'anirakamera

Chidziwitso chofunikira chokhudza Len ya kamera yakuwunika ndi kutalika kwake komanso kabowo.

Utali wolunjika: Ndiwo mamilimita angati a mandala omwe timagwiritsa ntchito nthawi zambiri.Nthawi zambiri 4mm, 6mm, 8mm, 12mm ndi zina zotero.

Kuchuluka kwa ma millimeters, mitundu yaying'ono ndi mtunda wapatali mandala amatha kugwira.Mwachitsanzo, kuyang'anira msonkhano ndi nyumba yosungiramo katundu, nthawi zambiri amagwiritsa ntchito lens 4 mm;Pakhomo lalikulu la nyumba yogona, nthawi zambiri amagwiritsa ntchito 6 mm;mpaka khoma ndi njira, nthawi zambiri amagwiritsa ntchito 12 mm.Inde, mandala ayenera kusankhidwa mosinthasintha malinga ndi momwe akugwiritsira ntchito.

Pobowo: Ndi nambala ya F pa mandala, nthawi zambiri F1.0, F1.2, F1.4, F1.6.

Kuchepa kwa F-nambala ya kabowo ndiko, kuwala kowala kwambiri, ndipo lens imakhala yokwera mtengo kwambiri. 

4. Kuwala kwa kameragulu

Makamera wamba omwe amawunikira amaphatikiza: Kuwala kwa Array IR, kuwala wamba kwa IR, Kuwala Koyera / Kutentha.

Cholinga cha gulu lowala ndikupereka kuwala kothandizira kwa lens usiku.Kwa kuwala kwa IR, mandalawa amatha kuzindikira ndikugwira kuwala kwa infrared ndikusandutsa chithunzi.Kuwala koyera / Kutentha nthawi zambiri kumaphatikizidwa ndi super starlight ndi module yakuda yowala, kuthandiza kugwira masomphenya okongola usiku.

5. Kamera nyumba

Makamera amabwera m'mawonekedwe osiyanasiyana, nthawi zambiri amakhala ngati zipolopolo, dome, ozungulira.Zida zanyumba ndi aluminiyamu ndi pulasitiki nthawi zambiri, zomwe zimafika ku IP66/IP67 yopanda madzi.

Ndizo zonse zomwe muyenera kudziwa za mawonekedwe onse a kamera.Kamera ya IP ya ELZONETA imagwiritsa ntchito tchipisi tapamwamba kwambiri ndi zowonjezera, imatenga cholakwika pamanja pa lens iliyonse ndikufananiza ndi mtundu, ndikuzindikira ukalamba kwa maola 24.Ichi ndichifukwa chake kamera ya Elzoneta imathabe kugwira ntchito bwino pambuyo pa zaka 4-5 zachizolowezi.
