Wireless cameras are devices that capture video or images without the need for physical cables. They use Wi-Fi or other wireless technologies to transmit data, making them easy to install and move around. This flexibility allows users to monitor areas without the hassle of running wires, making them popular for home security and surveillance. These cameras can often be accessed remotely through smartphones or computers, allowing users to view live footage from anywhere. Many wireless cameras also come with features like motion detection, night vision, and cloud storage, enhancing their functionality for both personal and professional use.
