New Sensing Technology for Optical Turnstiles to be Developed By Designed Security Inc. and Newton Security

March 3, 2004

Bastrop, TX and Seattle WA (February 24, 2004)- Designed Security Inc. (DSI), a leading manufacturer and provider of access management solutions, and Newton Security Inc., the global leader in the supply of machine vision single person detection systems, announced today an exclusive development agreement which will change the face of traditional Optical Turnstiles. Under this agreement Newton will modify its patent pending T-DAR® 3-D stereo camera tailgate and piggybacking technology to integrate with DSI’s Optical Turnstile product line.

“The new DSI Optical Turnstile system using overhead 3-D camera sensing will be designed to take powerful T-DAR tailgate detection and recording technology and combine it with proven DSI Optical Turnstiles to create the most foolproof system in the industry,” said DSI Vice President and Operations Manager Mark Crandall. “We are very pleased to have Newton Security, the world leader in machine vision tailgate detection, as our partner and I anticipate that our product fitted with T-DAR technology will revolutionize the Optical Turnstile market.” 

This new DSI Optical Turnstile, designed to be used in public and private lobby entry control applications, will improve tailgating and piggybacking detection while allowing for traditionally troublesome items like carts and luggage to pass through undetected. In addition, for the first time it will be possible to allow handicap access though Optical Turnstiles with full tailgate/piggybacking prevention. The agreement with Newton allows DSI to be the exclusive manufacturer and supplier of Optical Turnstiles with T-DAR technology in North America.

“We are very excited to be able to team up with DSI and to be able to combine our world leading technology with their state-of-the-art Optical Turnstiles,” said John W. Bramblet, President and CEO of Newton Security. “This new Optical Turnstile will be able to provide positive tailgate and piggyback detection even with the presence of luggage, carts and wheelchairs, thus makings its performance head and shoulders above any current Optical Turnstile.”
