Is e seòrsa de lionsa camara a th’ ann an lionsa CCTV varifocal a leigeas le atharrachadh fad fòcas caochlaideach. Tha seo a’ ciallachadh gun gabh an lionsa atharrachadh gus ceàrn seallaidh eadar-dhealaichte a thoirt seachad, a’ toirt cothrom dhut gluasad a-steach no a-mach air cuspair.
Bithear a’ cleachdadh lionsan varifocal gu tric ann an camarathan tèarainteachd leis gu bheil iad a’ toirt sùbailteachd a thaobh raon seallaidh. Mar eisimpleir, ma dh'fheumas tu sùil a chumail air raon mòr, faodaidh tu an lens a shuidheachadh gu ceàrn nas fharsainge gus barrachd den t-sealladh a ghlacadh. Air an làimh eile, ma dh’fheumas tu fòcas a chuir air raon no nì sònraichte, faodaidh tu gluasad a-steach gus sealladh nas mionaidiche fhaighinn.
An coimeas ri lionsan stèidhichte, aig a bheil aon fhaid fòcas statach, tha lionsan varifocal a’ tabhann barrachd sùbailteachd a thaobh suidheachadh camara agus còmhdach seallaidh. Ach, mar as trice tha iad nas daoire na lionsan stèidhichte, agus feumaidh iad barrachd atharrachaidh agus calibration gus dèanamh cinnteach gu bheil an coileanadh as fheàrr.
An coimeas ri aparfocallionsa zoom (“fìor”), a tha fhathast ann am fòcas mar a bhios an lens a’ gluasad (fad fòcas agus atharrachadh meudachaidh), tha lionsa varifocal na lionsa camara le fad fòcas caochlaideach anns am bi fòcas ag atharrachadh mar a bhios faid fòcas (agus meudachadh). Tha mòran de lionsan “zoom” ris an canar, gu sònraichte a thaobh camarathan lionsa stèidhichte, gu dearbh nan lionsan varifocal, a bheir barrachd sùbailteachd do luchd-dealbhaidh lionsa ann an malairt dealbhadh optigeach (raon faid fòcas, fosgladh as àirde, meud, cuideam, cosgais) na zoom parfocal.
