Lesson 1Overview of CCTV system architecture: cameras, recorders (NVR/DVR), storage, network, powerGet to grips with how cameras, NVRs or DVRs, storage units, network switches, and power setups connect to build a complete CCTV system that handles recording, remote viewing, backups, and room for growth in the future.
Roles of cameras, encoders, and recordersNVR vs DVR vs hybrid architecturesNetwork topology for CCTV trafficStorage sizing and retention planningRemote access, clients, and VMSLesson 2Regulatory and privacy considerations affecting camera placement and recordingDiscover how privacy laws, data safeguards, and sector guidelines shape where cameras go, how long footage is kept, audio recording rules, and notice signs, ensuring your CCTV setup stays legal and strong against checks or court matters.
