Lesson 1Overview of CCTV system architecture: cameras, recorders (NVR/DVR), storage, network, powerGrasp how cameras, NVRs or DVRs, storage solutions, network switches, and power systems connect to build a complete CCTV framework that enables recording, remote viewing, backup options, and scalability for future needs.
Roles of cameras, encoders, and recordersNVR vs DVR vs hybrid setupsNetwork layout for CCTV data flowStorage capacity and retention strategiesRemote access, software clients, and VMSLesson 2Regulatory and privacy considerations affecting camera placement and recordingDiscover how privacy regulations, data safeguards, and sector guidelines shape camera positioning, storage durations, audio recording, and notices, ensuring CCTV systems stay lawful and robust against inspections or disputes.
