Final Aiming
Initial aiming of the SP210 and the SP100 should be done as indicated previously in this
document.
For final aiming it is recommended that the bus be parked in the center of the lane on a
road that it would normally travel on.
Then deploy the stop arm and drive a vehicle past the bus with the Stop Arm camera system
operational.
The vehicle should make two passes – from back to front of bus and then from front to back
of bus.
For the first two passes the test vehicle should be driven very close to the bus in the adjacent
lane.
The next two passes the test vehicle should be in the center of the adjacent lane.
For the last two passes the vehicle should be driven so that it hugs the shoulder of the
adjacent lane.
Review the video and then fine tune the aiming of the SP-210 and SP-100. In most
cases the SP-100 will not have to adjusted however in Gatekeepers Systems
experience the SP-210 usually needs to be fine tuned (with respect to aiming) to
capture the license plates of the passing vehicle.
