IR LED Emitters 1-3W 840nm 850nm Rau Lub Koob Yees Duab

IR LED emitters 1-3W 840nm 850nm rau Lub Koob Yees Duab.

Lub luag haujlwm ntawm lub teeb infrared ntawm lub koob yees duab soj ntsuam

Nowadays, surveillance cameras have infrared lights, including two, four, or even six built-in infrared lights. So what are the functions of the infrared light on the surveillance camera?

The infrared camera is sensitive to infrared light, and the waveband is in the range of 800nm-1100nm. The principle of the infrared camera is that the infrared lamp emits infrared rays to illuminate the object, the infrared rays are diffusely reflected, and are received by the surveillance camera to form a video image.

Cov koob yees duab soj ntsuam tam sim no txhua tus muaj infrared hmo ntuj pom kev ua haujlwm, uas tuaj yeem hais tias yog tus qauv teeb tsa. Rau cov koob yees duab soj ntsuam hauv tsev, qhov dav dav infrared hmo ntuj pom kev deb li ntawm 10-20 meters. Cov koob yees duab infrared tau muab faib ua cov koob yees duab infrared zoo tib yam thiab dot-matrix infrared koob yees duab. Dot-matrix infrared koob yees duab zoo dua li cov koob yees duab infrared zoo tib yam, muaj qhov ntev irradiation nyob deb, zoo thiab meej cov duab zoo, thiab muaj lub neej ua haujlwm ntev dua li cov tib neeg. Ntxiv rau qhov zoo ntawm tiam thib ob, dot-matrix infrared teeb muaj qhov me me thiab txhim kho photoelectric conversion efficiency.
