Neither. WD Purple based off my research, most reviews, forum threads, and articles I read said the WD Purple drives are more reliable for surveillance cam setups.

Id be aiming for at least a 3TB. Skyhawk Surveillance, WD Purple, WD Gold, HGST UltraStar DC HC520, Seagate Constellation ES would all be suitable drives. 

If you only have a few cameras (especially if theyre only G3's), it really doesnt matter...you could just get a 2.5" 4TB Seagate Barracuda which would run cooler and less power as well.  If theyre G4 Pro's then you might need the larger disks due to the substantially higher data rate.
