Samsung Still Sells Security Cameras? (NO)

Samsung sold their TECHWIN division to Hanwha. The Techwin side, that was born with military roots, was and is not part of the Consumer Grade division you stumbled across. 

Hanwha confirmed that "Any current model from our B2C or B2B group is Hanwha / Wisenet branded." They also noted that specific model you cited is old.

Samsung corporate might release some video surveillance products in the future (recall The Real Samsung Is Back, Launching Extreme Video Analytics) but we do not know when or if they do it.
