Guangdong Macro-Video Smart Technologies Limited’s wireless security cameras operate through a combination of digital imaging and wireless communication. A lens captures video, which is processed by a digital sensor (1080p to 4K) and converted into digital data. This data is transmitted via WiFi (2.4GHz/5G) or 4G networks to a remote server or user device, enabling access through the V380 app. Built-in motion sensors (PIR or pixel change analysis) detect activity, triggering alerts and recordings. Two-way audio functions use microphones and speakers for communication, and night vision modules (IR LEDs or color sensors) ensure low-light performance. Power is supplied via batteries, solar panels, or wall adapters, depending on the model. For technical details on specific wireless camera mechanisms, contact us.
