Surveillance Cameras are security devices used to monitor, record, and sometimes stream real-time footage of specific areas to enhance safety and security. Available in various forms such as CCTV, IP, dome, bullet, and PTZ cameras, they can be installed indoors or outdoors depending on the surveillance needs. Many models offer advanced features like high-definition video, infrared night vision, motion detection, and remote access through smartphones or computers. Commonly used in hotels, offices, retail outlets, parking lots, and public spaces, they help deter theft, vandalism, and unauthorized access while providing valuable evidence for investigations. Modern systems often connect to digital or network video recorders (DVR/NVR) or cloud storage for convenient viewing and archiving.
