Overall processing system

The processing infrastructure (see below) is made of 3 x IP Video Cameras (Axis M1145-L), each having attached a Raspberry PI 3 (model B) platform. The communication is powered over a local LAN switch.

  • 128 GB Micro SDCard (high speed class 10) for loading operating system and storing data;
  • Upgraded switched Micro USB power source up to 2.5A;
  • Supported operating systems: Windows or Linux distribution (NOOB, Raspbian, Ubuntu, etc.);
  • Support for programming techniques: C/C++ şi Python;
  • Support for network storing: NAS (Network Attached Storage), up to 12TB, SATA III supporting JBOD, RAID 0 and RAID 1.

Demonstrator (TRL4)

The developed system (hardware-software) works in the following way: application startup and operator tracking of the live remote stream; a subject enters the visual range of the camera; the operator presses the Freeze Frame button and selects the subject to be searched for; the operator presses the Process Selection button and starts the function which searches the database of records; the results are displayed, in groups of 4, depending on the distance between the descriptor of the subject analyzed and the descriptors of the subjects in the database; the operator analyzes the correctness of the results.


The SPOTTER project is funded under research grant PN-III-P2-2.1-PED-2016-1065, agreement 30PED/2017 and is spanning over 18 months (January 2017 to June 2018).

The proposed technology will be capable of automatically finding the occurrence of a DROP instance by running specialized algorithms embedded directly on the IP video cameras.


  • Advanced DROP retrieving algorithms running on low resources embedded hardware platforms

  • Techniques for real-time identification and tracking capabilities from multiple video sources

  • Techniques for algorithms which can dynamically adjust the running parameters according to task variables
