Lesson 1Overview of CCTV system architecture: cameras, recorders (NVR/DVR), storage, network, powerUnderstand how cameras, NVRs or DVRs, storage, switches, and power systems connect together, making a full CCTV setup that supports recording, remote viewing, backup, and room for growth later.
Roles of cameras, encoders, and recordersNVR vs DVR vs hybrid setupsNetwork layout for CCTV dataStorage size and keeping time planningRemote viewing, clients, and VMSLesson 2Regulatory and privacy considerations affecting camera placement and recordingLearn how privacy laws, data protection rules, and industry standards affect where to put cameras, how long to keep footage, audio recording, and signs, so your CCTV setup stays legal and strong during checks or court matters.
