I-infrared (IR) i-sensors ye-break-beam yindlela elula yokubona ukunyakaza. Basebenza ngokuba necala elikhuphayo elithumela isibane somntu-ongabonakaliyo we-IR, emva koko umamkeli ngaphaya kwendlela enovakalelo kweso sibane sinye. Inzwa inoluhlu malunga ne-0.4m (16in). ngaphandle kweNdibano yeLens ye-IR kwaye malunga ne-2m (6ft) nayo. Sebenzisa kuphela iNdibano yeLens ye-IR xa kuyimfuneko njengoko iya kunciphisa uvakalelo xa isetyenziswe kuluhlu olusondeleyo.
Iingenelo zokusebenzisa inzwa ye-IR zezi: Izinzwa ze-infrared ziyakwazi ukubona ukukhanya kwe-infrared ukusuka kumgama omkhulu kwindawo ebanzi; Akukho ukuphazamiseka kwizixhobo zombane; Itekhnoloji ye-infrared ilula kwaye inexabiso eliphantsi kakhulu; Ikhaka lilula; Akukho zilayisensi zifunekayo.Photocell/omnye iisivamvo se-nfrared beam isetyenziswa jikelele ukuphakamisa iingcango, iingcango ezijikelezayo, iingcango ezityibilikayo, ukhuseleko eludongeni, ukhuseleko lwefestile kunye nebalcony, ukhuseleko lwendlu yokugcina impahla, iindawo zokupaka kunye nezinye iziza zokhuseleko zangaphandle. Wamkelekile ukuba ufunde ngakumbi malunga I-alam yesivamvo se-infrared kumvelisi we-infrared ye-Yaoertai.
