Aralin 1Paglalagay ng kamera at pagpaplano ng saklaw: entrance, reception, corridor, treatment room, pharmacy, parking, side passage, emergency exitTinutugunan ng seksyong ito ang praktikal na paglalagay ng kamera at pagpaplano ng saklaw para sa tipikal na site. Matututo kang magposisyon ng mga kamera sa entrance, corridor, treatment area, parking, at exit upang makamit ang identification, saklaw, at layunin sa kaligtasan.
Entrance, reception, at face captureCorridor, stairwell, at choke pointTreatment room at sensitive na lugarPharmacy, safe, at high-value storageParking lot, driveway, at side passageEmergency exit at evacuation routeAralin 2Indoor vs outdoor environmental rating (IP, IK) at pagsasaalang-alang sa pag-mountNakatuon ang seksyong ito sa mga environmental rating at pagpili ng mounting para sa maaasahang operasyon ng kamera. Matututo kang kung paano nakakaapekto ang IP at IK rating, temperature range, at mounting hardware sa durability, image stability, at long-term maintenance.
