Sensormatic AM Labels were once branded with the "DR" symbol to signify that they were genuine. Sensormatic stop using this designation in about 2002, when a number of cheap copies started appearing on the market. To give buyers the best opportunity to spot the difference they added the "claw in cross hairs" logo to their AM Labels and change the part number to: ZLDR-2.
