Hello Susanne

How do you use the camera? Is the camera activated by a movement, does it record continuously or do you want to operate it in interval mode (e.g. one picture every minute)?

I have several cameras in use in the meantime and am very satisfied with the product. When the SD memory is full, the oldest recording is overwritten, at least that's how I set it. With 2 MB per video of 15 - 30 sec. you can save many pictures.

I have partly linked the cameras with the Reolink Cloud. This variant also works perfectly. Either way, I have never reached the capacity limit. The battery life is also very good. With few activated cameras, it lasts 3 months.

Conclusion - 64 GB should be sufficient in motion-activated surveillance mode. For continuous operation, I recommend a cloud, NAS, etc. solution. solution.

Greetings M.
