Switch ea IR-CUT Dual Filter bakeng sa CCTV ip Security Camera Lense Projector
Ka hare ho khamera, CCD kapa CMOS e sebelisa sefe ea motšehare le bosiu hobane setšoantšo sa khamera se na le 'mala o sa fellang motšehare, phello ea khanya e tlase ea pono ea bosiu e mpe, kahoo sefe ea motšehare le bosiu e ke ke ea kopana le ts'ebeliso ea indasteri ea tlhahlobo ea CCTV ea lihlahisoa tsa dijithale tse nang le tlhaloso e phahameng, ha khamera e le 'mala, e tla sebelisa lets'oao la pulse ka bo eona ho etsa hore switch e fallele ho IR CUT filter, e tlose setšoantšo sa khamera haufi le ntho ea mebala ea mantlha, tlhaho. Ha khamera e le pono ea bosiu, e sebelisa lets'oao la pulse ho etsa hore switch e fallele ho AR filter hape, li-sensor tsena tsa setšoantšo li ka susumetsoa ho fihlela bolelele bohle ba leseli, e le hore khamera e be le khanya le qeto e betere ea setšoantšo, lintho li entsoe hore ho be bonolo ho li khetholla.
Switch ea IR-CUT ke sesebelisoa se behiloeng pakeng tsa sensor ea khamera le lense, 'me se lumella sefe ea IR-Cut ho beoa kapa ho tlosoa ka pele ho sensor, ho latela boemo ba khanya. Ke shutter ea mechini, hangata e tsamaisoang ke enjene, e nang le sefe ea NIR le likhalase tse se nang letho.
Likarolo tsa Motlakase:
1. Khanyetso: 25Ω±5Ω(mocheso o tloaelehileng)
2. Motlakase oa ho khanna: 3.4-4.5V
3. Hona joale: 155-225mA
Likarolo tsa Optical:
1. Botenya ba khalase: T=0.21mm
2. Tekanyo ea khalase: 8 * 9mm
3. Phetiso ea khalase (e khubelu):
| Bolelele ba maqhubu | Phetisetso |
| 400nm-420nm | T> 82%,Tave>88% |
| 420nm-620nm | T>90%, Tave>95% |
| 645±10nm | T=50%, slope 80%-20%<20nm |
