To clarify, you will NOT be able to record directly to the NAS from the IP camera. You can specify in the camera settings a FTP port and make it a ftp server to FTP into and download files from as well as have it upload screenshots to any ftp server of your choice, (eg, one you have running on your nas), but you cannot record directly to the NAS whatsoever.
Also, the camera does not have any remote playback software built in, you must download the remote playback application and then run it from any computer, then you will be able to access the IP camera for playback of video stored on the SD card. For live view you can view live video through your web browser.
Sorry for the delay in replying, im actually in southern california attending geovision certification training at the moment. .. sort of ironic in a way, lol.
