How Wi-Fi Cameras Work
Wi-Fi cameras capture video and audio through a built-in lens and microphone, then transmit that data wirelessly to your home network. From there, the footage can be streamed live to your smartphone, tablet, or computer through a companion app. Depending on the model, recordings may be stored locally on a microSD card, saved to a network video recorder (NVR), or uploaded to a cloud storage service.
Most modern Wi-Fi cameras connect to your router using the 2.4 GHz or 5 GHz frequency band. The 2.4 GHz band offers a longer range but slower speeds, while 5 GHz provides faster data transfer with a shorter range. Many cameras also include smart features such as motion alerts, person detection, night vision, and integration with voice assistants. Understanding these basics helps you evaluate whether a Wi-Fi camera will meet your reliability expectations.
