Lub tshuab tsis pom kev siv lub teeb muaj zog luv luv los tsim cov duab nrawm rau ntau yam ntaub ntawv ua haujlwm. Piv txwv li, txoj siv ceev nrawm nrawm nrawm nrawm nrawm nrawm thiab kuaj pom qhov tsis xws luag los ntawm lub tshuab tsis pom kev. Infrared thiab laserLEDflash teeb yog feem ntau siv nyob rau hauv luv luv thiab motion detection tshuab tsis pom kev. Kev ruaj ntseg system xa tawm high-speed, imperceptibleLED flashtxhawm rau txheeb xyuas cov lus tsa suab, ntes thiab khaws cov duab ruaj ntseg.

Ib qho kev sib tw rau tag nrho cov tshuab no yog tsim kom muaj lub zog tam sim no thiab lub sijhawm luv luv (microsecond) coj lub koob yees duab flash waveforms uas yuav kis tau rau lub sijhawm ntev, xws li 100 ms mus rau ntau tshaj 1 s. Nws tsis yog yooj yim los tsim lub sijhawm luv luv LED flash square yoj nrog lub sijhawm ntev. Thaum tsav tsheb tam sim no ntawm LED (los yogLED hlua) nce mus rau ntau tshaj 1 A thiab LED raws sij hawm yog luv rau ob peb microseconds, qhov kev sib tw yuav nyuaj dua. Ntau tus tsav tsheb LED uas muaj lub peev xwm PWM ceev yuav tsis tuaj yeem ua cov txheej txheem siab tam sim no nrog lub sijhawm ntev thiab lub sijhawm luv luv yam tsis muaj kev txo qis square yoj zoo yuav tsum tau ua kom zoo ntawm cov duab nrawm.
