Wireless outdoor floodlight cameras typically work by using a combination of motion sensors, a camera, and a wireless network to capture and transmit images or video. When the motion sensor detects movement, it triggers the camera to start recording or capturing images.

The camera may use infrared technology to capture clear images even in low-light conditions. Some cameras may also have a built-in floodlight that illuminates the area, providing better visibility and enabling the camera to capture clearer images or video.

The images or video captured by the camera are then transmitted wirelessly to a connected device, such as a smartphone or computer, where the user can view the footage. The user may also receive alerts on their device when the motion sensor is triggered, allowing them to quickly check the camera feed and see what caused the motion.

Wireless outdoor floodlight cameras can be a useful tool for home security, as they provide a visual record of any activity that occurs outside the home. They can also be used to monitor outdoor areas such as driveways, yards, and entrances to businesses.
