The TP-Link VIGI C240 network camera does not have a built-in feature to automatically take and save pictures at set intervals, such as every minute, directly to your computer via WiFi. However, you can use the camera's video streaming and snapshot capabilities through the VIGI App or the VIGI Security Manager software.

Here’s how you can achieve a similar result:
- Use the camera's video streaming feature to continuously capture video.
- Utilize the snapshot function within the VIGI App or VIGI Security Manager to manually or periodically capture still images.
- You can also set up motion detection or other smart events to trigger notifications and capture images when specific conditions are met, but this is not the same as taking pictures at fixed intervals.

For automated tasks like taking pictures every minute, you might need to use third-party software or scripting that can interact with the camera's API, but this is not a feature provided directly by the camera's default software.
