Hello,
Account limits for storage are only restricted by the subscription you purchase. You will want to make sure that your camera uploads according to the resolution, upload frequency, etc that you purchased with your subscription so that you are not over-using the parameters associated with your subscription. If you are uploading at parameters that exceed your subscription(s), you will receive notifications warning you that service could be interrupted if this is not resolved.
Please email support@cameraftp.com with any other questions.
Best,
CameraFTP Support
