Ke ao a me ka pō IR-CUT Dual Filter Switch no ka CCTV ip Security Camera Lens Projector
I loko o ke kāmela, hoʻohana ka CCD a i ʻole CMOS i ke kānana ao a me ka pō no ke kiʻi o ke kāmela i ke ao, a ʻaʻole maikaʻi ka hopena o ka mālamalama o ka ʻike pō, no laila, ʻaʻole hiki i ke kānana ao a me ka pō ke hoʻokō i nā noi ʻoihana kiaʻi CCTV o kēia manawa o nā huahana kikohoʻe wehewehe kiʻekiʻe. Ke kala ke kāmela, e hoʻohana koke ia i ka hōʻailona pulse e neʻe ai ke kuapo i ke kānana IR CUT, e lawe i ke kiʻi kāmela kokoke i ka mea o nā kala mua, ʻano. Ke ʻike pō ke kāmela, hoʻohana hou ia i ka hōʻailona pulse e neʻe ai ke kuapo i ke kānana AR, hiki ke hoʻokomo ʻia kēia mau mea ʻike kiʻi i ka nalu āpau o ke kukui, i ʻoi aku ka maikaʻi o ka mālamalama a me ka hoʻonā o ke kāmela, a maʻalahi hoʻi ke ʻike i nā mea.
ʻO ke kuapo IR-CUT kahi mea hana i kau ʻia ma waena o ke sensor kāmela a me ka lens, a hiki iā ia ke kau ʻia a wehe ʻia paha ke kānana IR-Cut mai ke alo o ke sensor, ma muli o ka pae hoʻomālamalama. He pani mechanical ia, i hoʻohana pinepine ʻia e kahi motika, me ke kānana NIR a me nā pane aniani maʻemaʻe.
