The main advantages of using CameraFTP service include:
(1) You don't need to buy a storage device. You can use CameraFTP cloud-based storage. It is much easier than a local storage device.
(2) CameraFTP storage is more secure. (A local storage device can be easily stolen or destroyed by an intruder!)
(3) With CameraFTP cloud-base storage, you can easily monitor or view the recorded footage from anywhere. You don't need to configure your router or setup DDNS.
If you bought a local NAS device, then it seems you DON'T want to use our Cloud-based service. In this case, you should contact your camera vendor for support, not CameraFTP.
If you do want to use our service, then you can configure your IP camera to upload image snapshots (or video clips) to CameraFTP's FTP server directly. If you have trouble configuring your IP camera, please email us your camera's configuration pages. We might be able to offer you more help. Of course, you can also get support from your camera vendor.
