With the navigation expansion module, the SharpZ3 system can add precise location information to license plate reads and can ensure that the patrol vehicle is accurately displayed on maps in Genetec Patroller™.
To provide the wheel tick information required for precise positioning, you can connect the base unit to the vehicle's VSS signal, or you can install the odometry sensor.
VSS connections
Odometry sensor connections
| Component | Description | |
|---|---|---|
| A | Navigation expansion module | |
| B | Satellite navigation antenna |
NOTE: Connecting the
satellite navigation antenna to the navigation expansion module provides more
accurate location information than connecting an antenna to the in-vehicle
computer.
|
| C | Reverse signal | The SharpZ3 system is usually connected to the vehicle’s reverse signal by tapping the reverse lights. |
| D | VSS or odometry sensor cable connection |
Connect the hardware to the base unit as shown in the
diagram.
NOTE: The wire that connects to the CGND pin is the drain wire from
the sensor cable.
|
| E | VSS signal | You can tap the VSS signal from the vehicle's power-train control module (PCM).
For more information, see the vehicle's electrical schematics
documentation. NOTE:
Some newer vehicles and electric vehicles do not
include a VSS or OSS.
|
| F | Odometry sensor | If the VSS signal from the vehicle is unavailable, you can install an odometry sensor. In general, a VSS provides more ticks per wheel rotation, resulting in more accurate odometry. For more information on the odometry sensor, see Installing the odometry sensor. |
