Security cameras are devices used to monitor and record activities in a specific area. They are commonly installed in places like homes, businesses, and public spaces to enhance safety and deter crime. These cameras can be connected to a recording system or viewed in real-time through a monitor or smartphone app. There are various types of security cameras, including CCTV (closed-circuit television) and IP cameras, which transmit video over the internet. Many modern security cameras come with features like night vision, motion detection, and two-way audio, making them versatile tools for surveillance and protection.
