The development of video surveillance technology has undergone significant transformations over the years. Let's explore the different eras that shaped the landscape of video monitoring:First Era: Analog Video SurveillanceThis era began in the 1970s with analog video surveillance equipment. The transmission was primarily achieved using coaxial cables, and the video signals were analog in nature. The recordings were stored on VCRs (Video Cassette Recorders). However, the limited storage capacity of VCR tapes led to frequent tape replacements to enable long-term storage. The analog video surveillance era faced challenges such as low automation efficiency and slow video...
