Gatekeeper Student Protector SP-210 System
Stop Arm Cameras Installation Guide
One of the most important issues when installing a SP-210 system is the placement of the cameras and
the subsequent aiming. The SP-210 should be mounted to the side of a bus and aimed as per the
diagrams below.
Figure 1
General Information
Aim the SP100 and the SP210 towards the rear so that they are more protected from rain, sleet,
hail snow, road spray etc. Note: If your state/province only requires a single rear license plate,
one of the two SP-210 cameras must be mounted aiming forward.
The SP-100 (overview camera) comes from the factory oriented to face the rear of the bus. If
this camera is mounted facing forward the image will be upside down. The SP-210 (license
plate capture camera) can be configured to face either forwards or backwards - see Figure 7.
The cameras should be mounted between the two black rub rails found on most school busses.
See Figure 1. If the bus does not have the black rub rail mount the cameras high enough so
they are not in the spray of the front tires. Do not mount the cameras too high (usually above
4.5 feet from the ground (approximately)). While we want the cameras high enough to avoid
road spray from the tires and passing vehicles we also want to minimize the vertical angle from
the camera to the license plate of passing vehicles.
Park the bus in a location where there is sufficient room on the drivers side to park a vehicle for
camera aiming purposes.
