Portable Mounting Pole Setup for Sidefire Radar
 

Click here for the Early Mounting Pole Setup video. Old system setup video shown here. New pole systems (in development) still use side strut and vehicle dead weight, stakes, or gabbons as stabilizers. 15m steel telescoping pole weighs 100 Kilos and requires a SUV for transport. 10m fiberglass/composite pole system will weight 10 Kilos and fit in a duffle bag.

Sidefire Radar

  • Sidefire radar is mounted to the camera pole to reduce the effort of manually verifying all loop data
  • Radar effectiveness is a function of height, angle, and offset, so the mounting system provides for these to be quickly changed and optimized
  • There are only a few electronic settings, but they can be confusing, so we developed our own GUI and driver that outputs Log170 event data compatible with VideoSync.
  • The following are amongst the videos developed to help explain some of unique charteristics of sidefire Radar to new users.
Click here for the RTMS-lone detection video.
Sidefire Radar works off the reflection of pulses of constant radius arcs, which can make consistent mapping to lanes problematic.
Click here for the RTMS-Multiple zone detection video.
Radar “arcs” reflect back at different times contingent on the lateral and vertical position of the vehicle’s reflective surfaces.
Click here for the RTMS-Occlusion detection video
The long wavelength of radar makes it the best sidefire mount detector to “look over” the occluding influence of large trucks.
Click here for the RTMS-Sensitivity detection video.
Physical placement of Radar is critical. “Sensitivity” is one of the few electronic parameters that can be set.
