To provide Genetec Patroller™ with more reliable geographic coordinates than a standard GPS device, you can connect the vehicle's odometry to an LPR Processing Unit that includes the AutoVu™ Navigation Option.

Before you begin

  • Wires to connect the LPR Processing Unit to the vehicle's odometry signal, reverse signal, and for the Vper connection are not included. You will need the following:
    • Vper: 20 AWG stranded conductor copper wire
    • REV: 24 AWG to 20 AWG stranded conductor copper wire
    • ODO: 24 AWG to 20 AWG shielded, twisted pair wiring is required for the VSS ODO +/- connection. Or, if you are installing the odometry sensor, a 22 AWG to 20 AWG jumper wire is required.


To install the Navigator option:

Connect the vehicle's odometry signal, reverse signal, and Vper to the LPR Processing Unit as follows:

LPR Processing Unit with Navigation option

Not supported. Do not connect.
Vper (optional)
The LPR Processing Unit includes an internal coin battery that maintains the time and almanac memory of the GNSS receiver when the LPR Processing Unit is powered off. The battery has an expected life of 5 years. Connecting a 20 AWG wire from the Vper port to the permanent 12V (+) power input greatly extends the battery life.
  • If the coin battery is drained, the time required for the AutoVu™ Navigation system to get a position fix at startup increases from 5 seconds to about 2 minutes.
  • The Vper port draws a very small current (a few microamperes).
Reverse input. Connect to vehicle’s reverse signal (required for inertial navigation). You can tap into the vehicle’s reverse lights to get this signal.
NOTE: The Reverse input supports active low/ground and active high/battery polarities.
- ODO and + ODO
Pulse odometry. Connect the signal from the VSS or odometry sensor.
