Although SIM-supported CCTV cameras may cost slightly more than Wi-Fi cameras due to monthly recharge requirements, they are reliable where internet connections are unavailable. They use data like mobile phones. Their maintenance becomes easier with long-lasting batteries and cloud storage.
SIM-supported CCTV cameras are specifically designed for areas where broadband access is not available. These cameras transmit data directly to the cloud or a mobile application using a 4G network.
