A 4G camera from Guangdong Macro-Video Smart Technologies Limited operates by leveraging 4G LTE network infrastructure to transmit video and data wirelessly, offering a flexible surveillance solution. Here’s a detailed breakdown of its working principle: 1) Video Capture: The camera’s image sensor captures video in HD resolution (e.g., 1080p), processed by an onboard chipset for optimal quality. 2) 4G Connectivity: A built-in 4G modem connects to cellular networks via a SIM card, transmitting video data over 4G LTE bands (compatible with major carriers). 3) Data Transmission: Video streams are encoded and sent to a remote server or directly to user devices (smartphones, tablets) through the V380 app, enabling real-time viewing. 4) Power Source: Cameras can be powered by AC adapters, rechargeable batteries, or solar panels (for off-grid models), with power management systems optimizing energy use. 5) Sensors & Alerts: Motion detection sensors trigger alerts, sending notifications and snapshots to users when activity is detected. 6) Storage: Footage is stored locally on microSD cards or remotely on cloud servers, accessible via the app. 7) Additional Features: Night vision (IR LEDs), two-way audio, and weatherproof housing enhance functionality and durability. This wireless design makes 4G cameras ideal for remote or temporary installations.
