In most case of clothing security in a retail environment both Electronic Article Surveillance (EAS) systems such as a Checkpoint system and a Closed Circuit Television System (CCTV) system are both desirable systems to have. To be successful though you must have correct expatiations of each.
A CCTV system is generally a PASSIVE system. How many retailers can afford to have an employee watch a CCTV system on a regular basis? In most cases involving clothing security or other retail goods a CCTV system is used in a spot situation where a potential thief is suspected. I have found that most uses of CCTV are after the fact or passive. Most Shoplifters know that you are not actively watching.
An EAS system is actively providing clothing security and protection of other retail goods. The tags cause an alarm at the door and of course attract employee attention. They work 24/7 as long as the Checkpoint system is maintained properly and powered.
