Lesson 1Overview of CCTV system architecture: cameras, recorders (NVR/DVR), storage, network, powerGet to grips with how cameras, NVRs or DVRs, storage, switches, and power systems connect to build a complete CCTV setup that handles recording, remote viewing, backups, and scalability for Australian installations.
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 Australian privacy laws, data protection guidelines, and industry standards shape camera positioning, storage durations, audio recording, and signage to keep your CCTV systems legal and robust against audits or legal challenges.
