Hikvision DS-3WR4G12C 4G Wi-Fi Router (SIM, LTE)

DS-3WR4G12C shares internet from the cellular network: insert a SIM card and the site gets Wi-Fi and wired Ethernet without a cable provider — on a construction site, warehouse, country plot or a new office before fiber arrives. External antennas improve reception far from the base station. The router is often used as a backup link for CCTV: if the main line drops, cameras keep streaming.
