If Wi-Fi is disconnected, the camera's work will depend on its specific functions and settings. Here are some possible situations:

Real-time monitoring function: If you use a real-time monitoring camera and rely on Wi-Fi to transmit real-time video streams, once Wi-Fi is disconnected, you will not be able to remotely view real-time video. However, some cameras have LAN functions that allow you to continue monitoring the camera in the local network environment.

Local storage function: Some cameras have built-in storage or support SD cards, so even if Wi-Fi is disconnected, the camera can still continue to record video and store it on the local storage device.

Cloud storage function: Cloud storage function may be affected when Wi-Fi is disconnected.
