Setting up Wide Entrance Counting in Software

For entrances that are wider than a double-doorway, you need to mount several CCTV cameras in a line across the ceiling. Each camera is attached to one Video Turnstile unit, and you need to tell the VT Setup program which Video Turnstile units are covering the wide entrance.

VT Setup has a row of tabs across the top. These take you to screens which let you connect to, and configure, your VT units.

  1. Select the VT setup tab.
  2. From the Select VT tab, choose one of the VT units that is monitoring a wide entrance. When you do this the selected VT unit stops counting and its count lights go on. When you are working with a VT unit which is not the first in the list, move to the Settings tab and click button 1, Read settings from module. This may take a few moments.
  3. Select the Entrance tab and choose "Part of a wide entrance".
  4. The units monitoring a wide entrance must have consecutive addresses. Choose whether your selected unit has its counting zone Left Edge linked to the unit at the next lower address, or the zone Right Edge linked with the unit at the next higher address, or both. It doesn't matter about the units' physical positions—they don't have to be next to each other.
  5. Click the Apply to VT button.
  6. If you haven't already done so, check your lens focal length and measure the distance between the camera and the floor. For focal lengths other than 3.6 mm, and camera heights other than 3 m, you will need to use the VT Setup software to change the camera height setting. This will affect the size of the counting zone and detection parameters.
  7. If necessary use the VT Setup software to alter the size and position of the counting zone.
