1, kunaka kwemotokari kushongedza - firimu;
Firimu ndiyo pfungwa yekutanga yevazhinji varidzi vemotokari nyowani yekushongedza, firimu rinogona kuparadzanisa ultraviolet mwenje, chiedza chezuva hachizotungamira mukati memotokari, kuvanzika kuri nani. Zvinokurudzirwa kuti varidzi vatsva vasarudze kuputika-proof membrane. Firimu inoputika ine maonero akasimba, zvisinei nemuvara, inonyatsojeka kubva pamotokari kusvika kunze, uye inogona kuchengetedza maonero akanaka usiku uye mumazuva ekunaya. Sarudzo yefirimu inoputika-inopikisa inofanirwa kufunga nezvekujeka, kujeka uye mhedzisiro yekudzivirira;
Mukuwedzera, firimu rehwindo remotokari, kunyanya firimu rehwindo repamberi kumativi ose ehwindo, rinofanira kusarudza transmittance inopfuura 85% inonyanya kukodzera, saka firimu repahwindo harifaniri kuchera makomba uye harina kukanganisa mutsara wekuona, kutyaira usiku kusvika kumashure kwemotokari mwenje unopenya pagirazi rekumashure rechiedza chakasimba chinopenya chinoratidza kushaya simba, kuitira kuti maziso aderedze. Zvakakosha kusarudza membrane yakanaka, uye zvakakosha zvakaenzana kusarudza chitoro chakanaka. Iyo tekinoroji uye yakapfava uye yakaoma mamiriro emufirimu anonyanya kuda. Semuenzaniso, nzvimbo isina guruva, midziyo yakakosha, yakajairwa maitiro ekushanda uye hunyanzvi tekinoroji, nezvimwewo, saka, iyo firimu haifanire kusarudza chitoro chemumugwagwa.
2, kunaka kwemotokari kushongedza - anti-kuba mudziyo;
Kuchengetedzwa kwemotokari ndiko kunonyanya kunetsa, saka varidzi vazhinji vezvigadzirwa zve anti-kuba vanosarudza kuve vakashongedzerwa, vakashongedzerwa nemagetsi anti-kuba mota vanogona kazhinji kudzora mukova, zviri nyore uye zvinoshanda. Sarudza anti-kuba mudziyo zvigadzirwa zvinofanirwa kutarisisa kuti kuburikidza neyakakodzera dhipatimendi kuyedzwa, kana kuratidza kwakabva chigadzirwa. Mukuwedzera, pari zvino, vamwe vagadziri vanotengesa modhi vakaisa anti-kuba system, saka havadi kuisa anti-kuba zvinhu.
