A 4G security camera is a surveillance device from Guangdong Macro-Video Smart Technologies Limited that uses 4G LTE networks to transmit video and data wirelessly, eliminating the need for wired internet or local network connections. These cameras are designed for security applications in areas with limited or no WiFi access, such as remote properties, construction sites, or rural locations. Key features include high-definition video capture (1080p or higher), motion detection with real-time alerts with the V380 app, infrared night vision for 24/7 monitoring, and weatherproof enclosures (IP66/IP67) for outdoor use. They typically include a SIM card slot for 4G connectivity, support local storage via microSD cards, and may offer cloud storage options. 4G security cameras enable remote access to live feeds and recordings from smartphones or tablets, providing flexible and reliable security solutions for various environments.
