Viewing the Camera Picture on a Television Monitor

It helps when you are setting up the Video Turnstile system to connect the CCTV camera to a television or a frame grabber. This lets you view the counting zone and verify that people are being counted correctly. Do this with the VT Setup software.

  1. Connect the video out on the VT or LVT to the video in on the TV screen.
  2. Connect the video lead to the VT unit and to the camera and then connect the power to the VT unit.
  3. Check the lights on the VT unit come on, and the up and down lights go off.
  4. Tune the channel to view the audiovisual channel, which is the channel used to watch the video.
  5. Check the picture from the camera.
  6. Make sure that the doors do not open all the way across the zone.
  7. For cameras covering nearby entrances make sure the zone does not overlap, or people may be counted twice.
  8. For cameras covering a wider entrance where several cameras are used make sure the zones overlap on the edges
  9. If you haven't yet done so, in the VT Setup software connect to a site in the Unit Select tab.
  10. Go to the Logger Setup tab and choose the controlling Logger from the Unit Address list.
  11. Select the VT setup tab. More tabs appear.
  12. In the Select VT tab check the Read Settings on address selection box then choose a VT unit from the list of those connected to your Logger. (To check you have the correct VT unit, click the "Flash Up/Down on this VT" button. The unit's count lights will flash.)
  13. Select the Camera/Video Out tab. Make sure your selected VT unit is ticked to show that it is connected to a video output. You can view up to four video pictures at once (and thus up to four monitors showing four different entrances). In each rack system there is a module with four video outputs: A, B, C and D. Connect the appropriate video output to your monitor.
  14. Click the Send to VT Units button.
