SCO terminals

  • SCO terminals provide a mechanism for retail customers to process their own purchases with minimal or no assistance, as shown in the following figure:

    Figure 4.              SCO terminal

     The SCO terminal that is used with this Ready Solution includes the following components:

    • Scanner—Scans the UPC barcode of the product being purchased
    • Touch-screen display—Provides the customer with a user interface during checkout. The touch screen displays the scanned item, the price of the item, the total cost of all purchases, the payment option, and other necessary information.
    • Video camera—Monitors and records the items being scanned
    • Weighting and bagging area—Includes a weight sensor
    • Alerting mechanism (for example, an overhead LED or cell phone-based notification)—Alerts retail associates to any issues during self-checkout

    Note: SCOs are not included as part of this Ready Solution. The customer must have SCOs installed at the retail store.

    Cameras

    This Ready Solution is agnostic to the camera model. SCOs are typically equipped with fixed-dome cameras. Cameras support H.264 or H.265 video compression and the video stream is decompressed/decoded in the T4 GPUs for further processing and inference. Dell Technologies recommends cameras that require Power over Ethernet (PoE) for ease of consistent deployment across all retail branches. Dell EMC PowerSwitch N3000 series or S3100 series switches can be used to power the camera and provide network connectivity.

    If SCOs across various retail branches have similar camera positioning, scanner positioning, lighting, and environmental factors, it is easy to train and deploy the initial model rapidly across all the retail stores, without needing further customization.

    At Dell laboratories, we tested this solution with an AXIS P1275 network camera with HDTV 1080p. The camera comes with an adjustable field of view that is enabled by rotating and tilting the camera sensor to the desired viewing direction.

    Note: Cameras are not included as part of this Ready Solution. The customer must have cameras installed at the retail store.
