A security camera system, or closed-circuit television (CCTV), is a surveillance solution designed to monitor and record activities within a specified area. Comprising cameras, a recording device (DVR or NVR), and a monitoring/display system, these systems enhance security by capturing video footage. Cameras come in analog or digital IP forms, with varying features like night vision and motion detection. Analog systems use coaxial cables, while IP systems rely on network cables for data transmission. The recording device stores captured footage on hard drives, with DVRs handling analog data and NVRs managing digital data from IP cameras. Users can monitor live feeds locally or remotely through the internet. Motion detection capabilities and alert systems further bolster security, allowing timely response to potential threats. Overall, security camera systems serve as effective tools for surveillance, deterrence, and evidence collection in various settings, from homes and businesses to public spaces.
