A Router Camera / 4G Camera is a wireless surveillance device that operates independently of traditional Wi-Fi networks by using a 4G SIM card or connecting via a router. This allows the camera to transmit live video to mobile devices, PCs, or cloud servers from virtually anywhere, even in locations without Wi-Fi connectivity.

It is ideal for remote monitoring of homes, offices, construction sites, farms, vehicles, or any area where network infrastructure is limited. Many models feature high-resolution video, two-way audio, night vision, motion detection, and cloud or SD card storage, making them versatile and reliable for continuous surveillance.
