Akribos by Giken

Simply, quickly and accurately count the number of people that visit your building, facility or event, using the ‘people count’ sensor ‘Akribos by Giken’. The Akribos is more than 95% accurate, and thus is one of the most reliable ‘people count’ sensors on the market: even during busy times.


Patented image analysis

The Akribos can be directly connected to your Ethernet and external data services via the ‘PoE’ connection on the sensor. The patented image analysis algorithms create a 3D virtual environment allowing accurate counting of people entering and leaving. Individually set counting lines track which way people go after entering, allowing you to analyse traffic flow from the point of entry. This valuable information can contribute to an increase in efficiencies including, sales and staff management, inventory management and climate control management as well as optimizing your energy consumption.

Real time image

Using the real time video output of the sensor over the ‘PoE’ network you can, in consultation with the system administrator, at any time and from anywhere log in to observe changes in the counting environment and, if necessary, make appropriate adjustments. You decide yourself how often the counting information is sent to the recipient server or ‘Cloud’. In case of failure of the ‘PoE’ network, the sensor, if equipped with the optional power-adapter, will save the counting information for 30 days on an internal flash-memory.

Quick and easy installation

Installing the Akribos is simple: place the camera in a strategic location and connect to your ‘PoE’ network. The sensor is suitable for detecting up to a distance of 4 meters by default. The purchase of a software license will enable you to increase the detection distance up
to 6 meters. Optionally, the power adapter can be used as an additional power backup. The settings for the IT coupling of the Akribos sensor to your network and data server or external data centre is actually a routine job for IT people.


The high quality camera and patented image analysis software can be adjusted in detail. Thus it is possible to define a counting area using
the eight counting directions, which can then be locally adjusted via your laptop or remote login procedure. The height of the objects to be counted can be set relatively accurately, which will enable you to exclude for instance, shopping carts and children from the count. Because of the 3D virtual mapping you eliminate, among others, shade detections and you can be assured of an accurate count in situations of high people traffic. The Akribos  functions in minimal ambient light and has a proven count accuracy of at least 95%.


Optex sensors guarantee optimum functioning, therefore we supply our products with a full 3-year warranty. The Akribos is also CE ClassA, FCC ClassA and RCM certified.
