Operating Modes
The main purpose of SmartLPR ® Access is to provide to the client applicationthe license plates
of the vehicles traveling in the lanes controlled.
The system has different operating modes as follows:
1. Software Trigger: the client application notifies SmartLPR ® Access of detecting vehicle
presence. The vehicle image is automatically captured and processed. The results obtained are
sent back to the client application.
2. Hardware Trigger: SmartLPR ® Access receives directly from a sensor, installed
beneath the tarmac, a vehicle presence signal and notifies the client application. Then, the
vehicle image is captured and processed. The results obtained are sent back to the client
application. When the vehicle leaves the lane, the client application is once again notified.
Special cases:
3. Pre-trigger: SmartLPR ® Access continually recognizes license plates as vehicles are
approaching and internally stores the best recognition obtained. When the client application
request the license plate, the unit immediately sends it.
●
Installation scenarios:
●
This operating mode should be used for those particular cases when the installation
has physical constraints and therefore it is mandatory to place the unit
immediately before or after the barrier or when the camera needs to be
embedded in the barrier.
●
However, we recommend using the software or hardware trigger mode whenever
possible.
●
As this mode works continuously, it is not possible to use it with color plate
recognition models (due to the fact they use white light) nor with WL (high
resolution) units.
