Tha lùtan beaga air an cleachdadh gu cumanta ann an camarathan CCTV gus ceàrn farsaing sealladh a ghlacadh gun fheum air corp camara mhòr. Tha na lionsan sin air an dealbhadh airson a bhith beag agus aotrom, a 'toirt cothrom dhaibh a bhith air am faladh no air fhilleadh a-steach do àiteachan beaga.
Leasanan binnole ag obair le bhith a 'cleachdadh toll beag bìodach gus cuideam a chuir air sensor ìomhaigh a' chamara. Bidh an toll ag obair mar lionsa, a 'lùbadh solas agus a' cruthachadh ìomhaigh air a 'sensor. Leis gu bheil fosg-sruthadh glè bheag aig Leasan Pinhole, tha iad a 'toirt doimhneachd mhòr de achaidh, a' ciallachadh gum bi nithean aig diofar astaran bhon Lens uile a 'cur fòcas air na Lens uile.
Is e aon bhuannachd de lionsan sìnteach an comas a bhith air leth. Air sgàth cho beag 's a tha iad air am falach gu furasta ann an grunn àiteachan, leithid ann an leacalladh mullach no air cùl balla. Tha seo a 'toirt orra fèill mhòr air adhbharan sgrùdaidh, agus iad a' ceadachadh sgrùdadh a dhèanamh air sgrùdadh a dhèanamh air sgrùdadh.
Ach, tha beagan chuingealachaidhean aig lionsan binnean. Air sgàth an t-sruthadh beag aca, is dòcha nach glac iad uimhir de sholas ri lionsan nas motha, a dh 'fhaodadh ìomhaighean càileachd nas ìsle a ghlacadh ann an suidheachaidhean aotrom ìosal. A bharrachd air an sin, seach gu bheil iad stèidhichte de loidhnichean farsaing cuibhrichte, is dòcha nach toir iad sùbailteachd lionsan glùine gus an fhaid fòcas atharrachadh gus ceàrn fhaicinn.
Gu h-iomlan, faodaidh lùtan pinolaire a bhith na inneal feumail airson siostaman sgrùdaidh CCTV, gu sònraichte nuair a bhios feum air sgrùdadh fuasglaidh. Ach, is dòcha gur iad an roghainn as fheàrr airson a h-uile suidheachadh, agus bu chòir beachdachadh air a h-uile roghainn, agus bu chòir beachdachadh air seòrsan de ghoireasan eile a rèir feumalachdan sònraichte an tagraidh.
