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, forming a complete CCTV setup that allows recording, remote viewing, backup, and room for growth.
Roles of cameras, encoders, and recordersNVR vs DVR vs hybrid setupsNetwork layout for CCTV dataStorage size and keeping time planningRemote viewing, apps, and management softwareLesson 2Regulatory and privacy considerations affecting camera placement and recordingLearn how privacy laws, data protection guidelines, and industry standards affect where to place cameras, how long to keep footage, audio recording, and signs, so that your CCTV setup stays legal and can stand up to checks or court cases.
