SIM-supported CCTV cameras are designed for locations without broadband. These cameras send data directly to the cloud or mobile apps via a 4G network, allowing the security system to be monitored from anywhere, at any time.
Conventional CCTV cameras need Wi-Fi or LAN connections, but SIM card cameras operate on mobile networks. This means they can be installed anywhere, even without wired internet. They are most effective in fields, remote areas, or temporary setups.
