Lesson 1Camera placement and coverage planning: entrances, reception, corridors, treatment rooms, pharmacy, parking, side passage, emergency exitsThis part go cover practical camera placement and coverage planning for common sites. You go learn how to position cameras at entrances, corridors, treatment areas, parking, and exits to achieve identification, coverage, and safety goals in clinics.

You go learn how IP and IK ratings, temperature ranges, and mounting hardware affect durability, image stability, and long-term maintenance in Liberia.

You go learn to match resolution, frame rate, lens, IR, WDR, and low-light performance to scene risk, distance, and regulatory needs in Liberian contexts.

This part go compare domes, turrets, bullets, PTZ, and specialized models, focusing on deterrence, coverage, tamper resistance, and maintenance for clinics.

You go learn secure streaming methods, user roles, authentication options, and how to harden remote viewing clients and mobile apps.

You go learn codec selection, bitrate control, PoE sizing, VLAN use, and how to avoid congestion and single points of failure in CCTV networks.

You go learn NVR selection, RAID levels, storage calculations, overwrite policies, and monitoring of disk health and capacity.

You go learn how to document system design, validate image quality, and maintain consistent configuration and audit records for Liberian use.

This part go cover masking, signage, retention limits, and evidence chain-of-custody, including documentation and secure handling of exported clips.
