Lub luag haujlwm ntawm LED sau lub teeb hauv kev soj ntsuam video
Infrared sau lub teeb yog ib qho chaw pabcuam teeb pom kev zoo uas feem ntau siv hauv kev soj ntsuam video, tshwj xeeb tshaj yog thaum lub teeb pom kev zoo nyob rau hmo ntuj, kev siv lub teeb ci infrared tseem tuaj yeem muaj cov duab zoo hauv qhov tsis tshua muaj teeb pom kev zoo. Muaj ob hom ntawm infrared sau lub teeb nyob rau hauv lub video soj ntsuam system: ib tug yog kev koom ua ke rau hauv lub soj ntsuam lub koob yees duab, thiab lub photoresistor yog siv los tswj nws kom tig los yog tua. Lwm qhov yog ntxiv cov khoom siv sab nraud cais ntawm qhov chaw ntawm lub koob yees duab soj ntsuam kom muab cov khoom siv hluav taws xob pab.
Infrared sau lub teeb yog ib hom LED sau lub teeb. LED sau lub teeb muaj qhov zoo ntawm qhov me me, kev siv hluav taws xob tsawg, lub neej ntev thiab siab ci. Tam sim no, feem ntau ntawm cov teeb ci hauv kev lag luam yog tsim los ntawm LED teeb hlaws. LED sau lub teeb Ntxiv rau lub teeb infrared, LED dawb lub teeb kuj siv dav. Piv txwv li, hluav taws xob qhov muag sau lub teeb nyob rau hauv pej xeem thauj.
Raws li nws txoj kev teeb pom kev zoo, LED puv lub teeb tuaj yeem muab faib ua lub teeb tas li thiab lub teeb strobe. Qhov ib txwm- ntawm lub teeb feem ntau yog siv hauv thaj chaw nyob, chaw ua si, chaw tsim khoom thiab lwm qhov chaw uas xav tau 24-teev saib video. Strobe teeb feem ntau yog siv thaum ntes cov duab, xws li hluav taws xob qhov muag sau lub teeb.
In the video surveillance system, most surveillance cameras integrate LED infrared fill light. Due to the low brightness of the infrared fill light itself, it will not affect the surrounding area at night. However, after the infrared fill light is turned on, the monitoring system screen will appear black and white. Of course, black and white pictures cannot meet people's requirements for video surveillance systems. Therefore, some manufacturers use low-illumination imaging or add peripheral LED fill lights to improve the problem that surveillance cameras cannot achieve color imaging at night.
Qhov qis- teeb pom kev zoo siv lub ultra- duab sensor thiab cim electron sib npaug thiab kev tswj lub suab nrov, uas tuaj yeem txhim kho cov duab zoo thaum hmo ntuj, thiab tseem tuaj yeem nthuav tawm cov duab yeeb yuj hauv lub teeb tsis muaj zog. Qhov zoo dua yog tias lub koob yees duab soj ntsuam tsis tsim lub teeb muaj zog heev. Qhov tsis zoo yog tias thaum lub teeb ambient tshaj qhov tsawg kawg nkaus illumination ntawm lub koob yees duab los yog tsis muaj lub teeb ci, lub koob yees duab yuav qhib infrared los xyuas kom meej cov duab, thiab cov duab yuav dub thiab dawb.
Lub peripheral LED sau lub teeb tsis muaj kev cuam tshuam rau kev hloov pauv ntawm lub teeb sab nraud. Vim tias nws tuaj yeem them cov teeb pom kev zoo los ntawm peripheral LEDs, thiab lwm yam, tag nrho - xim daim duab tseem tuaj yeem nthuav tawm los ntawm LED sau lub teeb yam tsis muaj teeb pom kev zoo. Txawm li cas los xij, nws qhov tsis txaus kuj tseem pom tseeb dua. Lub ci ci ntawm LED sau lub teeb thaum hmo ntuj yog siab dhau, uas tuaj yeem ua rau pom cov duab loj, thiab tseem tuaj yeem cuam tshuam rau lub neej ntawm cov neeg nyob ze.
Qhov tseeb, nws yog tsis yooj yim sua rau ib yam khoom los ua txhua yam -encompassing thiab zoo meej. Qhov tseem ceeb tshaj plaws yog yuav ua li cas siv cov cuab yeej siv tam sim no kom tau raws li qhov xav tau ntawm cov neeg siv los ntawm kev thov tsim nyog. Qhov tseem ceeb ntawm kev daws teeb meem kev soj ntsuam video kuj tau tshwm sim ntawm no.
