Vehicle Counter is a traffic monitoring application developed on the Axis Camera Application Platform (ACAP). It can be installed on most of the ACAP-enabled Axis camera server (such as the P33 camera servers), and it is capable of collecting meaningful statistics regarding the number of vehicles passing through the observed lanes, their length and speed. The application allows the user to set a number of virtual sensors and to decide how to aggregate the collected data. Sensors configuration can be made by means of a web application which is installed on-board and served by the camera web server. Statistics are stored on-board in the internal memory or SD card, and made available for download via a simple REST web service interface.
The video below shows an example of the configuration process for a street with two lanes.
The main innovation offered by Vehicle Counter concerns the integrated traffic monitoring system, embedded inside the camera. The following are the key features of the application:
Data collected by the Vehicle Counter application can be downloaded from the configuration web interface or be transmitted automatically to a remote server by means of REST/HTTP web services.
Below, two examples of vehicles statistics are reported, both coming from our prototype installation. The first figure shows the plot of vehicle per minute against time of day for the two ways of a four-lane road. The second figure shows the estimated speed distribution on the same road.
The EAP package for the latest version of Vehicle Counter can be downloaded for several Axis camera server based on ARTPEC-3 or ARTPEC-4 microprocessors (links below). In order to become fully functional, Vehicle Counter needs a commercial license that can be required at firstname.lastname@example.org. But you can also try it on your ACAP enabled camera for 30 days. To do this, visit the page www.axis.com/techsup/compatible_applications and select “Get trial key”. Choose “VehicleCounter from Magenta srl ver. 1.1” in the combo-box and enter the serial number of your Axis camera. You will receive a trial license key that can be installed onto the camera and will allow Vehicle Counter to run for a 30-days trial.
Any feedback is highly appreciated (email@example.com).
At the moment the following Axis cameras are supported: M320*, P134*, P330*, P334*, Q191*, Q192*, Q8721, M501*, P551*, P552*, P553*, P5544, Q603*, M105*, M110*, M3014, M111*, M311*, P134*, P3346, Q175*, P12**, M2014, M3006, M3007, P335*, P336*, P135*, Q160*.
In case your camera is not in the list, contact us (firstname.lastname@example.org).

Several AXIS camera servers with firmware version older than 5.40 are affected by a bug that prevents the user from installing ACAP applications that make use of certain system libraries (specifically, the fixmath library). The bug can only be fixed by Axis (which is informed) by distributing a new firmware version for the user to install. In the meantime, we developed our own workaround to allow our customers to use our Vehicle Counter application on their Axis camera even in the presence of this bug. Our workaround is distributed in the form of a separate ACAP application, called Magenta Patch. It does not need any license and is freely downloadable here. The linked package is for ARTPEC-3 cameras only. ARTPEC-4 cameras are unlikely to be affected by this issue since their firmware is usually newer. However, do not hesitate to contact us in case of problems during Vehicle Counter installation.
If the installation of Vehicle Counter fails, first try updating to the latest firmware version. If this does not fix the problem, try installing Magenta Patch and then re-install Vehicle Counter. Note that there is no need to run Magenta Patch. It is enough to keep it installed onto the camera. This will allow Vehicle Counter to install and run correctly.
If you are a developer of ACAP applications, you may want to use Magenta Patch to enable the workaround for your own applications. In this case, you can ask for support by writing an e-mail at firstname.lastname@example.org.
What follows is a list of known issues and common problems you may encounter while trying to use Vehicle Counter. If you experience a problem that is not listed here (or even if it is listed) write us at email@example.com.
