NOTE: Your account is a CameraFTP.com account. This is a question about your CameraFTP.com service.
I checked it and noticed that your Download Bytes Usage is much higher than an average CameraFTP user. It has reached the free service limit. I have reset it for you now.
If you order a CameraFTP subscription, you will get a lot more download bytes/month. The chance of reaching maximum download bytes will be very low.
In general, if it is for regular home/business surveillance service, CameraFTP offers far more download bytes than you need. But if you share your cameras with a lot of people or publish your cameras, and if many people watch your cameras for a very long time, then you probably will need more download bytes.
