Configuring IntelliSight Devices: Camera Setup

Adding a Stop Line Presence Zone

This setup is only applicable to IntelliSight Cameras. This type of zone is defined at the stop line of the intersection and detects the presence of vehicles and/or bicycles as they enter the zone. One or more zones can be defined for an intersection. The number is dependent on the requirements of the site. After laying out the physical zones, conditions and actions can be defined for each zone.
  • Before a zone can be added camera calibration must be done.
  • Including overlapping zones in a configuration is not recommended as this can cause poor detection performance.
  • Adding or editing a zone while playing video may cause the operation to appear delayed or jerky.
  • "Exiting Vehicle" data collection require that there be at least 2 car lengths beyond the leading edge of the zone visible in the image. Also, in order for vehicle direction to be reported, there must be room on the image to see vehicles turning.
  • A single zone covering multiple lanes is not recommended for Data Collection as counts may not be accurate for shared zones. Also, single zones for multiple lanes is not recommended when using Pulse or Snappy outputs.
1. On the Device screen, click Zone Setup.
2. Do you want to create zones from the calibration or manually?
Calibration
Manually
Continue with the next step.
Proceed to Step 7.
3. Click Zones From Calibration. 4. Select the lane layout from the list.
  • No Turn Lanes: one zone appears, covering all lanes defined in the calibration.
  • Left Turn Lane: two zones appear, one for a left turn and one covering the remainder of the lanes defined in the calibration.
  • Right Turn Lane: two zones appear, one for the a right turn lane and one covering the remainder of the lanes defined in the calibration.
  • Left and Right Turn Lanes: two or three zones appear, one for a right turn lane, one for a left turn lane and if more than two zones were defined in the calibration, one covering the remainder of the lanes.
  • Preserve All Lanes: a zone for each lane defined in the calibration appears.
The zone layout done on the calibration screen appears on the image and the lanes are defined according to the selection. Right-click on a zone to see its defined direction; if neither Right Turn or Left Turn are checked, the zone is a thru zone.
5. Add/delete zones or modify zone positions as required. 6. Proceed to Step 12.
7. Click Add Zone. 8. Move the cursor to one of the corner markers then click and drag to the desired location. 9. Repeat for each corner until the zone covers the detection area and lane lines are arranged so that they line up with the zone lines.
10. To add additional zones similar to the previous one, right-click on the previous lane to display the following. Otherwise, just click Add Zone and repeat Step 8 and 9.
11. Select whether the new zone is to be added to the left or right of the current zone. The new zone is added to the configuration.
  • Because the original zone is probably not a perfect square or rectangle, the distance measurement shown for the new zone will be different from the original.
12. For zones not already designated as right or left, if vehicles can exit the zone by making a right or left turn, do the following.
  • Right-click on the zone.
  • Under Turn Direction, select the appropriate check box.
  • Click elsewhere on the image.
13. To change the zone description, highlight the description in the Easy Setup section and type a new description. Any number of alphanumeric and special characters can be used. 14. Assign Conditions, Actions, and Video Overlays as required.
  • By default the vehicle presence condition is selected for each zone. In addition, green is selected for the zone display color when a vehicle is detected and gray when no vehicle is present in the zone. There is no default output assigned.
  • For each selected condition (vehicle and bicycle presence) an output must be assigned unless the Set Output action is removed in either the Zones Explorer or Actions Explorer section.
  • The Show Video Overlay check box is used to display overlays only when video is playing. The Show Setup Controls check box is used to display overlays on the Zone Setup screen for both static images and video.
  • After all zones are defined and configured, it is recommended that the configuration be archived (see Saving an Archive File).
15. When complete, click Apply Changes. Changes go into effect immediately and can be viewed live. 16. Do you want to add an Advance Zone?
