You can start with 3 drives?  Is this a RAID5 array?

What about backups and redundancy?  Have you considered cloud storage at
all?  You could set the local head-end to keep only 24-48 hours on-site
(dramatically reducing number of disks) and unlimited archives on a
cloud server(s).  You may find it's much cheaper and reliable to use a
connected "Simple Storage Service".

	Standard Storage	Reduced Redundancy Storage
First 1 TB / month	$0.125 per GB	$0.093 per GB
Next 49 TB / month	$0.110 per GB	$0.083 per GB
Next 450 TB / month	$0.095 per GB	$0.073 per GB
Next 500 TB / month	$0.090 per GB	$0.063 per GB
Next 4000 TB / month	$0.080 per GB	$0.053 per GB
Over 5000 TB / month	$0.055 per GB	$0.037 per GB

License for what, users or cameras?

Definitely.  CAT6 or are you going to try with CAT5?
