Switch yeIR-CUT Dual Filter yeCCTV ip Security Camera Lens Projector
Mukati mekamera, CCD kana CMOS inoshandisa sefa yemasikati neusiku nekuti mufananidzo wekamera une ruvara rwakati wandei masikati, chiedza chehusiku hachina kunaka, saka sefa yemasikati nehusiku haigone kusangana nekushandiswa kweCCTV yekutarisa zvigadzirwa zvedhijitari zvine hungwaru, kana kamera ine ruvara, inoshandisa otomatiki chiratidzo chekurova kuti switch ifambe kuenda kuIR CUT filter, ichibvisa mufananidzo wekamera pedyo nechinhu chine mavara ekutanga, zvisikwa. Kana kamera ichiona husiku, inoshandisa chiratidzo chekurova kuti switch ifambe kuenda kuAR filter zvakare, sensors iyi yemufananidzo inogona kukurudzirwa kusvika kuhupamhi hwese hwechiedza, kuitira kuti kamera ive nekupenya kwakanaka uye kugadziriswa kwemufananidzo, zvinhu zvakaitwa kuti zvive nyore kuziva.
Switch yeIR-CUT mudziyo unoiswa pakati pesensa yekamera nelenzi, uye unobvumira sefa yeIR-Cut kuiswa kana kubviswa pamberi pesensa, zvichienderana nehukuru hwekuvheneka. Ishutter yemakanika, inowanzo shandiswa nemota, ine sefa yeNIR nemagirazi asina chinhu.
