Magirazi eCCTVikozvino dziri kushandiswa zvakanyanya, asi kuti zvienderane nemamiriro ezvinhu chaiwo, zviyero zvakawanda zvehunyanzvi uye zvinodiwa chaizvo zvekushandisa zvinofanirwa kutariswa, zvakaita sekutsanangura zvakajeka chinangwa chekutarisa, daro rekutarisa, uye nharaunda yekutarisa.
Muchinyorwa chino, tichaongorora zvakadzama masarudzo akakodzera malenzi eCCTV emamiriro akasiyana-siyana.
Kusarudza lenzi yeCCTV yakakodzera mamiriro ezvinhu chaiwo kunoda kutariswa kwakazara kwezvinhu zvinotevera:
1.Tsanangura zvinodiwa nemamiriro ekutarisa
Usati wasarudza lenzi yeCCTV, zvakakosha—sedanho rekutanga—kutanga waona zvinodiwa zvekutarisa mamiriro ezvinhu aunoda kushandisa. Kutanga, zvakakosha kujekesa hunhu hwemunhu ari kutarisa uye nzvimbo yacho.
Semuenzaniso, simbisa kana chinangwa chiri chekuona nzvimbo yakakura kana zvinhu zvidiki, kungave kureba kwekutarisa kuri kupfupi kana kure, uye kana nzvimbo yekutarisa iri mukati kana kunze, uye mamiriro emwenje aripo. Pakupedzisira, lenzi yakakodzera inofanira kusarudzwa zvichienderana nezvinodiwa izvi zvakasiyana zvekutarisa.
2.Kufananidza ma parameter e lenzi dzekiyi
Kureba kwefocus, aperture, field of view, uye resolution zvese zvinhu zvakakosha zve lens zvinofanirwa kutariswa:
(1) Kureba kwefocal. Kureba kwefocal chinhu chakakosha pakusarudza nzvimbo yekuona uye daro rekutarisa. Kureba kwakasiyana kwefocal kunoenderana nemamiriro akasiyana ekutarisa: kureba kwefocal kupfupika, nzvimbo yekuona yakafara; zvakasiyana, kureba kwefocal, ndiko kukura kwedaro rekuona.
Semuenzaniso, kureba kwe 2.8mm kwakakodzera kutarisa daro riri mukati memamita gumi uye nzvimbo yekuona inosvika madhigirii zana, zvichiita kuti ikodzere kutarisa marekodhi emari emukati, maelevator, nedzimwe nzvimbo dziri mukati menzvimbo yakati; kureba kwe 8mm kana kupfuura kwakakodzera kutarisa daro rinodarika mamita gumi nemashanu, zvichiita kuti ikodzere kutarisa zvakadzama kure munzvimbo dzakakura dzakadai sematura nenzvimbo dzekupaka mota.
Kureba kwefocal chinhu chakakosha kufunga nezvacho
(2) Aperture. Aperture inosarudza huwandu hwechiedza chinopinda mukamera, zvichikanganisa zvakananga mhedzisiro yemifananidzo husiku. Aperture yakakura inobvumira chiedza chakawanda kupinda, zvichikonzera mifananidzo yakajeka munzvimbo dzisina chiedza chakawanda uye zvichiita kuti ive yakakodzera mamiriro ekutarisa husiku pasina chiedza chekuwedzera. Aperture diki inonyatsokodzera nzvimbo dzine chiedza chakawanda uko kunofanirwa kujeka kwenzvimbo yese - senge pamitsetse yekugadzira kana mumatura.
Munzvimbo dzekunze kana dzimwe nzvimbo uko chiedza chekunze chinochinja-chinja zvakanyanya, zvinokurudzirwa kusarudzalenziine chinhu chinonzi auto-iris, chinogona kuchinja otomatiki zvichienderana nemamiriro echiedza anochinja.
(3) Munda wekuona. Munda wekuona wakabatana zvakanyanya nehurefu hwefocal, uye unosarudza zvakananga huwandu hunogona kuvharwa nelenzi. Kazhinji, malenzi ane angle yakafara ane munda wekuona wakakura kupfuura 90°, zvichiita kuti akwanise kutariswa munzvimbo dzakakura dzakadai senzvimbo dzekupaka mota nenzvimbo dzeveruzhinji; malenzi ane telephoto ane munda wekuona uri pasi pe30° uye akakodzera kutariswa kwakadzama, kure kure—semuenzaniso, muzvishandiso zvinosanganisira kuzivikanwa kweplate yerezinesi uye kuzivikanwa kwechiso.
(4) Kugadziriswa. Kana resolution yelenzi yakakwira, mufananidzo wacho uchava wakajeka. Zvisinei, resolution yacho inofanira kuenderana nezvinodiwa nechinhu chiri kutariswa. Hazvisi nani nguva dzose kuva neresolution yakakwira.
Panguva imwe chete, resolution yelenzi pachayo inofanirawo kuenderana neresolution yekamera. Makamera ane resolution yepamusoro anofanira kusanganiswa nemalenzi ane resolution inoenderana, zvikasadaro mipendero yemifananidzo ichadzimwa; malenzi ane resolution yepamusoro akabatanidzwa nemakamera ane resolution yakaderera zvinogumawo nekurasikirwa neresolution.
Semuenzaniso, lenzi ye2-megapixel inogona kusangana nezvinodiwa zvekutarisa zvakadzama, zvakaita sekuona marongerwo emifananidzo yevanhu uye maitiro avo, uye yakakodzera kutarisa makorori nematura akajairwa.
(5) Kuisa uye masensa. Kuisa lenzi kwakajairika kunosanganisira M12, C, uye CS mounts. Usati waisa, zvakakosha kuve nechokwadi chekuti lenzi yakabatana ne interface yekamera; kutadza kuita izvi kunogona kukonzera kutadza kuburitsa mufananidzo wakajeka kana kutokonzera kukuvara kwemuchina.
Nheyo imwe chete inoshandawo pahukuru hwesensa: denderedzwa remufananidzo welenzi rinofanira kuenderana nehukuru hwesensa yekamera; zvikasadaro, mufananidzo wacho unogona kusvibiswa zvakanyanya, zvichiita kuti zvisakwanise kutora mufananidzo wakajeka.
Kufananidza ma parameter ema lenzi eCCTV kwakakosha
3.Kureba kwekuisa uye kona
Kureba kwekuisa uye kona yelenziuye kamera inokanganisawo mhedzisiro yekutarisa. Kazhinji, kamera yakakwira, nzvimbo yayo yekufukidza yakatwasuka inowedzera. Pakutora maonero anotarisa pasi kubva panzvimbo yakakwirira, zvakakosha kuwedzera urefu hwefocal kuitira kudzivirira kutambisa nzvimbo pamusoro pefuremu.
4.Kugona kwekutarisa husiku
Kana mamiriro ekushandisa achida kutariswa husiku, zvakakoshawo kufunga nezve lenzi inotsigira infrared (IR) night vision uye ine automatic IR cut filter function, kuitira kuve nechokwadi chekuti mifananidzo yakajeka yekutarisa masikati neusiku.
5.Kuchinjika kwezvakatipoteredza uye kugara kwenguva refu
Pakusarudza magirazi eCCTV, zvakakoshawo kufunga nezvekugona kuchinjika uye kugara kwenguva refu kwenzvimbo—kunyanya magirazi akagadzirirwa kushandiswa panze. Kunyatsotarisirwa kunofanirwa kupihwa kana aine zvinhu zvinodzivirira, zvakaita seguruva uye kudzivirira mvura, kudzivirira kupinda kwemvura kunogona kukonzera kukuvara kwegirazi kana kutadza kuona zvakanaka.
Kusarudzwa kwemalenzi eCCTV kunofanirwawo kufunga nezvekuchinja-chinja kwezvakatipoteredza uye kugara kwenguva refu
6.Zvirongwa zvekusarudza mamiriro akasiyana ekushandisa
(1) Kutarisa mumba: Yakagadzirirwa kufukidza makamuri ese—akadai seimba yekutandarira—sarudzo inosarudzwa ndeyekuyera makona akawandalenziine urefu hwefocal hunosvika 4mm uye nzvimbo yekuona inosvika 70 degrees, zvichibvisa kudiwa kwekugadzirisa angle kakawanda.
(2) Masuo ekupinda nekutarisa mukoridho: Chinangwa chikuru chekutarisa nzira dzakamanikana, iyi nzira ine chinangwa chekubata kufamba kwevanhu nezvinhu zviri pakati nepakati. Magirazi ane urefu hwe2.8mm kana 4mm anokurudzirwa kuti ave nechokwadi chekuti akafukidzwa kwenguva refu. Kureba kwekuisa kwe2.5 kusvika 3 metres kunokurudzirwa kudzivirira kona yekudzika yakawandisa, iyo inogona kukonzera kuvharika kwechiso.
(3) Kutarisa nzvimbo yekupaka mota/yekuchengetedza: Chinangwa chikuru ndechekuona zvakajeka mapurati erezinesi kana hunhu hwevashandi. Unogona kusarudza lenzi ine urefu hwe8mm kana hwakareba kuti uone mapurati erezinesi uye mhando dzemotokari dziri kure nemamita 15-30 uye kuti uone zviso zvakajeka. Paunenge uchiisa panze, iva nechokwadi chekuteerera chiyero chelenzi yacho chisingapindi mvura uye chisingapindi guruva.
(4) Kutarisa zvitoro/hofisi: Nzvimbo yacho yakavharirwa zvishoma, uye zvakakosha kuti maonero neruzivo zvienderane. Chinangwa chikuru chiri pane nharaunda yese neruzivo. Magirazi e4mm kana 6mm anogona kusarudzwa. Kana zvichidikanwa kunyora zvakajeka maitiro ekutengeserana kana chimiro chechiso, lenzi ye6mm inokurudzirwa.
Kune sarudzo dzakasiyana dzezviitiko zvakasiyana zvekushandisa
(5) Kutarisa nzvimbo yakakura yakashama: Munzvimbo dzakakura dzakadai semasikweya, lenzi imwe chete haikwani kuvhara ruzivo rwese. Kazhinji zvinodiwa kuisa musanganiswa wemalenzi. Semuenzaniso, lenzi ye2.8mm inogona kushandiswa kuona panorama, nepo lenzi ye8mm inogona kushandiswa kuona ruzivo rwenzvimbo yakatarwa. Lenzi yevarifocal inogona kusarudzwa kuti igadzirise urefu hwefocal nenzira inochinjika.
(6) Kutarisa nzvimbo dzemigwagwa: Nzvimbo dzakaita semigwagwa mikuru dzinoda kutariswa kure zvakanyanya kuti dzione zviri nyore marekodhi emotokari kana zvinhu zviri kure nemazana emamita. Masisitimu anogona kuve nemalenzi ekusarudza ane urefu hwepakati kubva pa30mm kusvika 120mm; kana akabatanidzwa nemakamera einfrared thermal imaging, anovimbisa kutariswa kwakanaka kunyangwe panguva dzehusiku kana mumamiriro ekunze asina kunaka.
Muzviitiko zvakasiyana, kutarisisa kwakasimba kanamagirazi emhando dzakasiyanainogona kusarudzwa zvichienderana nezvinodiwa zvekutarisa. Kazhinji, malenzi ekutarisa akasimba haana kudhura uye akagadzikana, zvichiita kuti akwanise kutarisa zvinangwa uye mamiriro ezvinhu apo daro rakatarwa; malenzi e-varifocal, kune rumwe rutivi, ane urefu hwefocal hunogadziriswa, zvichiita kuti akwanise mamiriro ezvinhu apo daro rekutarisa kana chinangwa chinofanira kugadziriswa nenzira inochinjika.
