Mafirita einfrared cut, dzimwe nguva anonzi mafirita eIR kana mafirita anotora kupisa, akagadzirirwa kuratidza kana kuvharira mawavelength ari pedyo neinfrared achipfuura nechiedza chinoonekwa. Anowanzo shandiswa mumidziyo ine mabarabhu echiedza anopenya (akadai semasiraidhi nemapurojekita) kudzivirira kupisa kusingakoshi. Nekuda kwekunzwa kwakanyanya kwemasensa mazhinji emakamera kuchiedza chiri pedyo neinfrared, kunewo mafirita anoshandiswa mumakamera e solid-state (CCD kana CMOS) kudzivirira chiedza cheinfrared. Mafirita aya anowanzo kuve neruvara rwebhuruu nekuti dzimwe nguva anovharirawo chimwe chiedza kubva kumawavelength matsvuku marefu. Mafirita eIR anogona kuve akajeka, grey, gradient kana akasiyana-siyana mavara akasiyana.

Kusiyana neziso, masensa akavakirwa pasilicon (kusanganisira maCCD nemasensa eCMOS) ane kunzwisiswa kunosvika mu near-infrared. Masensa akadaro anogona kusvika 1000 nm. Mafirita eIR anoshandiswa kushandura chiedza chinotumirwa kuburikidza nelenzi kuenda kumufananidzo wemufananidzo kudzivirira mifananidzo isingatarisike seyakajairika. Mafirita eIR-transmitting (passing) kana kubvisa mafirita eIR-blocking emufekitori anowanzo shandiswa mumifananidzo yeIR kuti apfuure chiedza cheIR uye avhare chiedza chinoonekwa uye cheUV. Iyi firita inoita seyakasviba kuziso, asi inoonekera kana ichionekwa nemidziyo inonzwa IR.

Pakutanga, mafirita eIR aishandiswa mukutora mifananidzo yemafirimu kuti awedzere kunaka kwemifananidzo yemavara matema nemachena. Nekuwedzera mafirita emavara akasiyana, vatori vemifananidzo vanogona kuwedzera kudzika, kunatsiridza kusiyana, uye kuderedza kupenya kunogona kukanganisa mufananidzo.

Kune mafirita akasiyana-siyana anowanikwa ekuona michina yemuindasitiri. Mafirita anokubvumidza kuwana mhedzisiro inoshamisa, kuvandudza kuoneka kweruzivo rwakadzama, uye kazhinji anorerutsa mabasa ako ekuona michina zvakanyanya.

Semuenzaniso, firita yebandpass inosanganiswa nechiedza chiri kushandiswa ichakubvumidza kuti usefe chiedza chekunze chinowanzo pararira zvakanyanya. Uyewo, mumashandisirwo akajairika, hunhu husingaonekwe hwezvinhu hunowanzoonekwa uchishandisa mafirita akakodzera.

CHANCCTV inokupa mafirita akasiyana-siyana emhando dzakasiyana dzemalenzi ese.
