Operations ⚙️

• Evercam Specified Hardware 📹: ANPR camera & Context Camera + Kits and Masts

• Mains Power. We avoid solar given the number of other things that must go right for a successful Gate Report.

• Location for the mast within a region not closer than 5m and/ or not more than 20m from the centrepoint of detection.

  • Not more than 45º to the left or right of the traffic centreline, and;

  • Between 0 and 45º vertical offset from the centre of detection (20 degrees is optimal). 📐
    

• If nighttime detection is required, suitable lighting is needed. 💡
  

Context Camera on a Single Mast 👁️‍🗨️

• Bullet Varifocal camera tends to give the best results.

• Try to have the ANPR centreline in the centre of the Bullet FoV.

• Height >6m with an angle of 10 to 45º to the centre-top of the vehicle.

  
  

  
  
  

Context Camera on a Separate Mast 👁️‍🗨️

• The trailer side should be visible to distinguish between trucks that look similar on the front.

• The trailer top should be visible to show what is inside the truck. 🚚
  

• Clear & visible entrance with no occlusions (trees, cranes, people, containers, etc).

• Between 1.5 and 2 truck lengths should fit inside the ROI.
