Video surveillance is a comprehensive security measure, utilizing cameras and recording devices to monitor activities. Management, recording, and storage solutions include workstations, digital video recorders (DVR), and network video recorders (NVR). Transmission of video signals is enabled by encoders, decoders, and other transmission equipment. Specialty cameras, such as body-worn and explosion-proof cameras, cater to niche surveillance needs. Analog and IP surveillance cameras, including dome and bullet types, offer a range of visual monitoring capabilities. Accessories enhance system performance.
