Please help me out, you seem to have knowledge in this area.
I have these TV-IP301W cameras and I cant record any video and I just added a NAS. I didnt know I couldnt record footage or I would have gotten a regular DVR system. Is there any other way to record footage off these cameras.

A quick look at the product description does not reveal any direct-to-NAS recording feature. Looks like you have to run a Windows application.
