This technology helps deter criminal activity, gather evidence, and enhance overall safety by providing real-time monitoring and recording of events. Video surveillance systems can be used in various settings, such as homes, businesses, public spaces, and government facilities, and often include features like motion detection, remote access, and integration with other security measures. Overall, video surveillance is a vital tool for maintaining security and peace of mind.
