Tips and Tricks

There are several actions you can take to keep NoPileups working at its very best.

Streamlining Load-On Procedure

NoPileups works best when it can make good models of every vehicle. The system creates its models using the enter eye during load on. If a car stops inside the eye, NoPileups will misjudge the car’s length and trigger a stop. You can always hit the Ignore or Ignore This Vehicle button to keep things moving, but every ignored vehicle is one you’ll need to watch yourself. Keeping the load-on process smooth is the best way to keep the tunnel safe.

Camera Cleaning and Maintenance

NoPileups works best when it has a visual of the cars in the tunnel. Bad lighting, dirty cameras, and cameras covered in water negatively impact NoPileups’ performance. To keep NoPileups working in tip-top shape, you will need to keep the cameras in your tunnel clean and in working order. Follow these tips to maintain optimal camera performance.

  • Clean every camera daily and as needed. A regular cleaning schedule prevents soap scum and mineral buildup from blocking the camera view. Daily tunnel cleaning can result in soap and spray, so it is important to give the cameras a quick detailing afterward.
  • Clean the camera housing with glass cleaner and a paper towel. Do not use a broom or brush.
  • Do not power-spray the camera or nearby junction boxes. Power-sprays cause camera housing to crack, which allows condensation to enter and damage the camera.
  • If scum or mineral buildup does occur, do not use a razor blade or other abrasive tool to clean the camera. Glass cleaner, a paper towel, and a bit of fingernail scraping will safely remove buildup.

You can find detailed instructions for camera maintenance in Camera Care and Maintenance.

Select the camera from the NoPileups Dashboard by clicking on its corresponding yellow dot and choosing the appropriate time needed to clean the selected camera from the Block Stops dropdown menu. Once you have chosen a time, select Block Stops. The camera will now have a yellow border on the Live View. The camera will automatically return to a live state once the chosen time has expired.


  • If program errors repeatedly stop the conveyor for seemingly no reason, you can disable NoPileups by clicking Autostop Enabled from the NoPileups Dashboard. Autostop Enabled will turn off NoPileups monitoring. NoPileups will still track vehicles but it will not prevent any potential collisions.
  • If you have an issue with one camera triggering repeated stops, use the Block Stops function and check the camera for damage and visibility.
