Umahluko phakathi kwe-850NM kunye ne-940nm ye-LED

Iikhamera zokuzingelaYiba sisixhobo esibalulekileyo kubazingeli kunye nenzondelelo yasendle, ebavumela ukuba babambe imifanekiso esemgangathweni kunye neevidiyo ze-wildlife kwindawo yazo yokuhlala. Elinye lamacandelo aphambili kwikhamera yokuzingela yi-infrared (ir) ekhokelwa, esetyenziselwa ukukhanyisa le ndawo kwiimeko ezinokukhanya ezinokukhanya ngaphandle kokwazisa izilwanyana kubukho bekhamera. Xa kufikwa kwiikhamera zokuzingela, iintlobo ezimbini eziqhelekileyo ze-IR yi-IR yi-80NM kunye ne-940NM. Ukuqonda umahluko phakathi kwezi ntlobo zimbini ze-LEDs kubalulekile ukukhetha ilungeloIkhamera yemidlalo Ngeemfuno zakho ezithile.

Umahluko ophambili phakathi kwe-850NM kunye ne-940NM ikhokelele ubuxoki kwi-wavelength yombane otyhidiweyo. I-wavelength yokukhanya ilinganiswa ngeNanometer (NM), nge-850nm kunye ne-940nm ibhekisele kuluhlu oluthile lwe-infrated. I-850NM ikhokelele ekukhanyiseni oko kubonakala kancinci kwiliso lomntu, ibonakala njengento etyibilikayo ebumnyameni. Kwelinye icala, i-940NM ikhokelele ekuthobeni ukukhanya okungabonakali ngokupheleleyo kwiliso lomntu, kuyenza ilungele ukubekelwa indawo yokuhlala kunye nokujonga izilwanyana zasendle.

Kwimigaqo esebenzayo, ukhetho oluphakathi kwe-850NM kunye ne-940nm ikhokelela kuxhomekeka kwisicelo esithile sekhamera yokuzingela. Abazingeli abafuna ukubeka esweni iindlela zemidlalo kunye nomsebenzi wasendle ngaphandle kokuphazamisa izilwanyana, i-940NM ye-940NM kukhetho olukhethiweyo. Ukukhanya okungabonakaliyo kuqinisekisa ukuba ikhamera ingabonakali, ivumela indlela yokuziphatha yendalo engaphezulu kwaye iqinisekile ukuba ifakwe kwikhamera. Ukongeza, i-940nm ye-940 ikhokelela ekunciphiseni izilwanyana zasebusuku, zenza ukuba ibe yeyona ndlela ibalaseleyo yokufaka imifanekiso kunye nevidiyo yezidalwa ezikhoyo ebusuku.

Kwelinye icala, i-80mm ye-80m inokuthi ilungele ngakumbi ukufuduselwa kunye neenjongo zokhuseleko. Ngelixa ikhupha i-funkm ebomvu ebomvu engabonakali ebantwini, isenokufunyanwa zizilwanyana ezithile ngombono wobusuku ovuthelweyo, njengohlobo oluthile lwexhama. Ke ngoko, ukuba eyona njongo iphambili kukugcina i-terespassers okanye ilisoyibe indawo yokhuseleko, i-80NM ye-80m inokuthi kukhetho olungcono ngenxa yokukhanya kwayo okubonakalayo.

Kubalulekile ukuba uqaphele ukuba ukhetho oluphakathi kwe-850NM kunye ne-940NM kukhokela ikwachaphazela uluhlu kunye nokucaciswa kwezakhono zobusuku bekhamera. Ngokubanzi, i-850NM ye-LED ibonelela ngokukhanya okungcono kwaye kuluhlu olude xa kuthelekiswa ne-940nm. Nangona kunjalo, umahluko kuluhlu luncinci, kwaye urhwebo lokungabonakali olwandisiweyo nge-940nm lupasine luye lukhuni olungenelelo oluncinci kuluhlu lwe-80NM.

Ukuqukumbela, umahluko phakathi kwe-850nm kunye ne-940nm ikhokelela kwiikhamera zokuzingela i-bills phantsi ukubonakala kunye nokungabonisi. Ngelixa i-80NM ikhokelwa linika ukukhanya okungcono kunye noluhlu, i-940NM ibonelelwa ngokupheleleyo, iyenza ukuba ibe kukhetho olukhethwayo lwendawo yokuhlala kunye nokubek 'esweni. Ukuqonda iimfuno ezithile zokuzingela kwakho okanye ukuphononongwa kuya kukunceda wenze isigqibo esinolwazi xa ukhetha phakathi kwezi ntlobo zimbini ze-LEDIikhamera zasendle.
