Lesson 1Camera placement and coverage planning: entrances, reception, corridors, treatment rooms, pharmacy, parking, side passage, emergency exitsThis part covers practical camera placement and coverage for typical Gambian sites. You will learn to position cameras at entrances, corridors, treatment areas, parking, and exits to meet identification, coverage, and safety goals in our clinics.

You will learn how IP and IK ratings, temperature ranges, and mounting hardware affect durability, image steadiness, and long-term care in our hot climate.

You will learn to match resolution, frame rate, lens, IR, WDR, and low-light to scene risks, distances, and local rules.

This part compares domes, turrets, bullets, PTZ, and special models, focusing on deterrence, coverage, tamper resistance, and maintenance for our clinics.

You will learn secure streaming, user roles, authentication, and how to strengthen remote viewing clients and mobile apps for local use.

You will learn codec choice, bitrate control, PoE sizing, VLAN use, and avoiding congestion and single failures in CCTV networks.

You will learn NVR choice, RAID levels, storage calculations, overwrite policies, and monitoring disk health and capacity for clinic needs.

You will learn to document system design, check image quality, and keep consistent configuration and audit records for courts here.

This part covers masking, signage, retention limits, and evidence chain-of-custody, including documentation and safe handling of exported clips.
