Kunyangwe iwe uchitsvaga chengetedzo yeruvara husiku chiratidzo kana infrared yekunze chengetedzo kamera, yakakwana, yakanyatsogadzirwa sisitimu inotsamira pakusarudza yakanakisa uye yakanyatsokodzera chiratidzo chekuchengetedza husiku kamera.Musiyano wemutengo pakati pekupinda-level uye yepamusoro-yekupedzisira mavara ekuona husiku makamera anogona kubva pamadhora mazana maviri kusvika kumadhora zviuru zvishanu.Naizvozvo, kamera uye mamwe maperipheral (senge IR mwenje, lenzi, zvivharo zvekudzivirira, uye magetsi emagetsi) zvinofanirwa kutariswa zvizere usati wafunga kuti ndeipi modhi yekusarudza.
Zvikamu zvinotevera zvinopa nhungamiro pane zvekufunga usati wasarudza uye nekuisa yakaderera-mwenje yekuchengetedza kamera.
Ngwarira kuvhura kwekamera
Saizi yeaperture inosarudza huwandu hwechiedza chinogona kupfuura nemukati me lens uye kusvika kune iyo sensor yemufananidzo-yakakura apertures inobvumira kuratidzwa kwakawanda, nepo madiki achibvumira kushoma kuratidzwa.Chimwe chinhu chakakosha kucherechedzwa ilenzi, nekuti kureba kwakaringana uye saizi yekuvhura inopesana.Semuenzaniso, 4mm lenzi inokwanisa kuwana aperture yef1.2 kusvika 1.4, nepo 50mm kusvika 200mm lenzi inongokwanisa kusvika pakakwirira f1.8 kusvika 2.2.Saka izvi zvinokanganisa kuratidzwa uye, kana zvichishandiswa neIR mafirita, kurongeka kwemavara.Shutter kumhanya inokanganisawo huwandu hwechiedza chinosvika sensor.Iyo yekumhanyisa yekuvhara yehusiku chiratidzo chekuchengetedza makamera inofanirwa kuchengetedzwa pa1/30 kana 1/25 yekutariswa kwehusiku.Kuenda zvishoma pane izvi kunozokonzera kusajeka uye kuita kuti chifananidzo chisashande.
Chengetedzo kamera idiki yekuvhenekera mwero
Chengetedzo yekuvhenekesa kwekamera inotsanangura hudiki hwekuvhenekesa mamiriro ekurekodha inooneka-yemhando yevhidhiyo / mifananidzo.Vagadziri vekamera vanotsanangura kukosha kwakaderera kweaperture kune akasiyana apertures, inova zvakare yakaderera kupenya kana kunzwa kwekamera.Matambudziko anogona kuitika anogona kumuka kana huwandu hwekamera hwekuvhenekesa huchikwira kupfuura infrared illuminator's spectrum.Muchiitiko ichi, chinhambwe chinoshanda chichakanganiswa uye chifananidzo chinoguma chichava chimwe chenzvimbo inopenya yakakomberedzwa nerima.
Paunenge uchimisa marambi uye IR illuminators, vanoisa vanofanirwa kutarisisa kuti mwenje weIR unovhara sei nzvimbo inoda kutariswa.Chiedza che infrared chinogona kubvongodza madziro uye kupofumadza kamera.
Huwandu hwechiedza icho kamera inowana chimwe chinhu chinogona kukanganisa zvakanyanya kuita kwekamera.Sezvo chirevo chese, chiedza chakawanda chakaenzana nemufananidzo uri nani, unova unonyanya kukosha pamadaro makuru.Kuwana mufananidzo wemhando yepamusoro kunoda yakakwana yakavakirwa-mukati IR mwenje, iyo inoshandisa simba rakawanda.Muchiitiko ichi, zvingave zvakanyanya kudhura-inoshanda kupa yakawedzera IR mwenje kutsigira kuita kwekamera.
Kuti uchengetedze simba, mwenje-inokonzeresa magetsi (yakavhenekerwa, inofamba-yakabatidzwa, kana inopisa-inonzwa) inogona kuiswa kumoto chete kana ambient mwenje inowira pasi penhanho yakakosha kana kana mumwe munhu asvika kune sensor.
Iyo yekumberi-yekupedzisira magetsi ekutarisa system inofanirwa kuve yakabatana.Paunenge uchishandisa IR mwenje, zvinhu zvekufunga nezvazvo zvinosanganisira IR mwenje, iyo IR LED, uye ikozvino uye voltage yemagetsi.Kureba kwetambo kunokanganisawo hurongwa, sezvo ikozvino inoderera nenhambwe yafambwa.Kana kune akawanda IR mwenje kure kure kubva kune mains, kushandisa DC12V yepakati magetsi inogona kuita kuti marambi ari padyo neiyo sosi yemagetsi ave over-voltage, nepo marambi ari kure kure asina kusimba.Zvakare, kuchinja kwemagetsi kunogona kupfupisa hupenyu hwemarambi eIR.Panguva imwecheteyo, kana voltage yanyanya kuderera, inogona kukanganisa kushanda nekuda kwekushayikwa kwechiedza uye kusakwana kwekukanda kure.Naizvozvo, AC240V simba rekupa inokurudzirwa.
Kupfuura chete specs uye madheti
Imwe pfungwa isiriyo yakajairika ndeyekuenzanisa nhamba nekuita.Vashandisi vekupedzisira vanowanzovimba zvakanyanya pamapepa ekhamera pavanenge vachifunga kuti ndeipi kamera yekuona husiku ichaita.Muchokwadi, vashandisi vanowanzotsauswa nemadatabase uye vanoita sarudzo zvichibva pamametrics kwete kuita chaiko kamera.Kunze kwekunge tichienzanisa mamodheru kubva kumugadziri mumwe chete, iyo dhatabheti inogona kutsausa uye isingatauri chero chinhu nezve kunaka kwekamera kana kuti ichaita sei muchiitiko, nzira chete yekudzivisa izvi ndeyekuona kuti kamera inoshanda sei usati waita sarudzo yekupedzisira.Kana zvichibvira, ipfungwa yakanaka kuita bvunzo dzemumunda kuti uongorore makamera anotarisirwa uye kuona maitiro aanoita munzvimbo iyi masikati nehusiku.
