Lesson 1Overview of CCTV System Structure: Cameras, Recorders (NVR/DVR), Storage, Network, PowerLearn how cameras, NVRs or DVRs, storage, switches, and power connect to make a full CCTV setup that allows recording, far access, backups, and growth later.
Jobs of cameras, encoders, recordersNVR against DVR against mixed setupsNetwork plans for CCTV data flowStorage size and keeping time plansFar access, users, and VMSLesson 2Rules and Privacy Matters Affecting Camera Placing and RecordingFind out how privacy laws, data safety rules, and work standards change where cameras go, how long to keep videos, sound recording, and signs, so CCTV setups stay right by law and strong in checks or court looks.
