If you are connected to a SharpX, you can change the settings of the external cameras.

What you should know

SharpX cameras are automatically detected when connected to the LPR Processing Unit. The Interfaces you see in the portal depend on how many cameras you have connected to the LPR Processing Unit and how many single board computers (SBCs) are on the LPR Processing Unit. For example, if you have four cameras connected to an X1SU LPR Processing unit (one SBC) you will see all four interfaces: Interface 1, Interface 2, Interface 3, and Interface 4. On an X2S/X2SU LPR Processing unit (two SBCs), you will only see two interfaces at a time in the portal (either Interface 1 and Interface 2, or Interface 3 and Interface 4) since the camera settings are configured on a separate portal page for each SBC. The interfaces represent the following:

Interface 1 and Interface 2
These correspond to the camera interfaces 1 and 2 on the faceplate of the LPR Processing Unit. This means you are connected to the SBC controlling the SharpX camera units that are physically connected to the first pair of camera interfaces.
Interface 3 and Interface 4
These correspond to the camera interfaces 3 and 4 on the faceplate of the LPR Processing Unit. This means you are connected to the SBC controlling the SharpX camera units that are physically connected to the second pair of camera interfaces.

Tire cameras used for wheel imaging are not detected by default. If a tire camera is connected it must be configured manually by selecting A tire camera is connected to this interface and selecting the model. Tire cameras can be configured on Interface 2 and Interface 4 providing no LPR camera is connected to those interfaces already.

Procedure

  1. Log on to the Sharp Portal.
  2. Click the Configuration page.
  3. Select the LPR resolution for the LPR camera.
    The resolution you select depends on several factors, such as the type of Sharp used, the type of lens, etc. Your initial site survey should provide you with the information you need to select the proper resolution.
    Tall (1024 x 946)
    Used for most law enforcement installations where the camera must read multiple lanes of traffic. This setting generally provides the best results in the majority of cases.
    Wide (1280 x 808)
    Used for most parking enforcement installations, especially for parallel parking.
    Standard (1024 x 768)
    Used in specific situations as determined by the site survey.
  4. (Optional) For certain installations, additional precision is required for the location coordinates of plate reads. This precision might be required if, for example, ticketing agents are dispatched from a head office when infractions are detected by patrol vehicles. Use the following steps to increase plate read location precision:
    NOTE: You can include the location coordinates of license plates as a custom field in plate reads. For more information on adding user custom fields to reads and hits, see the Security Center Administrator Guide.
    1. In the Camera settings section, click the Edit button for the Camera position.
      The Camera position settings window opens.
    1. Define the Position of the front of the camera in respect to the GGNS antenna location by entering the X, Y, and Z measurements in centimeters.
      In the following example, the SharpX camera is installed above the driver's position (left-side drive).
      Tip: Click for more information on the required measurements.
    2. Define the Orientation of the camera by entering the Pan, Tilt, and Roll in degrees.
      NOTE:
      • Pan: R_SH_ConfiguringA value of 0 degrees indicates that the camera is pointing directly ahead of the vehicle. To take this measurement, you need a 0° baseline. To do this, make a chalk line down the center of the vehicle roof. If available, you can use the vehicle’s front and back logos to help you mark the center line of the vehicle. Then use a digital protractor to measure the pan of the camera relative to the 0° baseline. Alternatively, you could print a paper protractor to make the required measurements.
      • Tilt and roll: We recommend using a digital inclinometer to take these measurements.
    3. Click OK.
      The camera position settings are displayed in the portal.
  5. To capture context images in 640 x 480, select the Capture high definition context images option.
    The standard definition context images are 320 x 240 pixels.
  6. Click Save.
  7. If you are using an X2S/X2SU LPR Processing Unit (two SBCs), click Configure the other unit on the Status page under Actions.
    If there is a warning associated with a camera, there will be a yellow warning icon next to the interface number. Hover your mouse over the warning icon to see the details.
