Video surveillance refers to the use of video cameras and recording equipment to monitor and record activities within a designated area. The footage captured by video cameras can be used for real-time monitoring by security personnel or stored for later review. Video surveillance is widely used in a variety of settings, including homes, businesses, government buildings, and public spaces. The goal of video surveillance is to provide a visual record of activities, deter criminal activity, and aid in the investigation of security incidents. Video surveillance systems may include features such as motion detection, remote access, and integration with other security systems, such as alarms and access control.
