A security camera is a device used to monitor and record activities in and around a building to ensure safety. It is commonly placed in strategic locations, such as entrances, hallways, or parking areas, to detect any unusual activity. Security cameras are often connected to a recording system or viewed in real time through a screen. They are used in homes, businesses, and public spaces to deter crime, monitor for safety hazards, or provide evidence in case of incidents. Many modern security cameras also have features like motion detection and remote access via smartphones.
