Sierzega is a bluetooth device that does traffic counting for Neighborhood services and Traffic Enforcement at the PD. You connect a laptop or device to the unit via bluetooth and it is importted into a program to analize the data.
As of 10/2018 the POC is:
Neighborhood Services: Greg Carr
PD: Josh Lake
Here is the PIN number for your SR4 Radar. I have attached a help sheet as well.
