Using my book 3TB NAS with small business security cams

All,

My wife and I are opening a small business and need to put in a few security cams.  IS there a setup where I can use my mybook NAS to record-i.e. use it like a DVR for the camreas.  Any suggestions from anyone with experience in any way are great andf welcome.  Thanks in advance.

Not sure about this one…

Have you consider getting a harddrive that is more suitable for this task?

The drive will not record anything unless you add software that does the job and that can transfer to the drive on the network
