Lesson 1Camera placement an' coverage plannin': entrances, reception, corridors, treatment rooms, pharmacy, parkin', side passage, emergency exitsDis section cover practical camera placement an' coverage plannin' fi typical sites. Yuh wi learn how fi position cameras at entrances, corridors, treatment areas, parkin', an' exits fi achieve identification, coverage, an' safety goals.
Entrances, reception, an' face captureCorridors, stairwells, an' choke pointsTreatment rooms an' sensitive areasPharmacy, safes, an' high-value storageParkin' lots, driveways, an' side passagesEmergency exits an' evacuation routesLesson 2Indoor vs outdoor environmental ratings (IP, IK) an' mountin' considerationsDis section focus on environmental ratings an' mountin' choices fi reliable camera operation. Yuh wi learn how IP an' IK ratings, temperature ranges, an' mountin' hardware affect durability, image stability, an' long-term maintenance.

Dis section compare domes, turrets, bullets, PTZ, an' specialized models, focusin' on deterrence, coverage, tamper resistance, an' maintenance.
