Mapping a drive to a network path and using a network path directly into a device like the camera DVT are two different things.

If you map a drive to a network path in WINDOWS you just use the mapped drive letter in your device.

If the device accept network paths you just enter the proper network path information for the computer/NAS share and that's it.

Of source in either case you have to have a valid share setup on the computer/NAS.
