CDA DIGITAL SECURITY SCREENING SYSTEMS

CDA identification systems provide turnkey solutions, designed specifically for security screening of passengers at airports, transportation terminals, and other secure entry points. DX9000 PLUS™ is a completely integrated system using the PelcoMATCH™ Facial Recognition System in conjunction with the Pelco DX9000 digital video recording system. The PelcoMATCH™ system is based upon the world-renowned, proven, facial recognition software. The system analyzes the facial features of individuals as they pass through security screening, and compares these features with file photos of individuals who are wanted for arrest or questioning. If a positive comparison is made, the system quickly alerts authorities both locally and/or remotely for a fast and appropriate response.
Security is no longer totally dependent on an alert and vigilant onsite officer. DX9000 PLUS™ can screen persons passing through a checkpoint against a database of thousands of facial images in just seconds. In addition, Pelco's DX9000 PLUS™ can simultaneously alert officers around the facility or around the country so appropriate response measures are taken every time. All activity around the screening area is recorded and users can quickly access views of the area before, during, and after the alarm event occurred. Remote users can also switch to a live view to assess activity in real time.

DX9000 PLUS™ is designed to be installed in security screening areas where individuals are asked to pass through metal detection equipment under the supervision of security personnel. The visible portion of the system is housed in an attractive 6 foot high, 10-inch diameter heavy gauge, high-grade metal post that is located about fifteen feet past the metal detector. One of these posts is utilized for each metal detector lane. This post houses a very advanced, high-resolution, low-light capable digital video camera, along with the indicator lights that help control traffic flow past the detector. Each metal detector has a cordoned off passenger lane area which the passenger must walk through after passing the metal detector. Video from the camera is connected to the system processor for analysis and recording. Camera angles are carefully controlled, and the camera is optimized to provide the best possible video for analysis and facial recognition. A local view station is designed to handle up to four lanes of passengers. The video recorder/processor is connected to remote viewing terminals via modem or network connection.

How It Works:
As the passenger passes through the metal detector, the processor will capture and analyze successive video frames. The recognition system extracts facial features in the video and measures the geometric patterns of the face. This reduces the description of the individual to a complex data set that is unique to that individual. The extracted facial measurements are then compared against a database of subject individuals.
When a match occurs, the view station automatically displays the captured, live picture next to the reference picture. In addition, the screen flashes an attention-grabbing notice along with an associated text field. The text can be customized with information such as the person's name, nationality, and physical description. It could also be used to provide appropriate specific Additionally, the system is programmed to control the signal lights in the detector posts.
When the subject person passes through the metal detector, the indicator displays the word "WALK" in green. The system is designed to make the face comparison in the time it takes to walk through the cordoned off area. If a match is made with the database, the indicator changes to a red "STOP", and an audible alert is provided.
