Bird Collision Avoiding System (BCAS)



The Bird Collision Avoidance System (BCAS) consists of multiple interconnected modules. Main functions of the system are:

  • Detection
  • Recognition
  • Deterrence
  • Monitoring
  • Data logging


Once an object is detected, the data is analysed by a proprietary software. When the system recognises the flying object as a bird, it positions the acoustic module, which emits a proprietary sound signal. Thus, Acoustic Startle Reflex (ASR) is evoked and the bird changes its course, flying away.

This unique deflection approach causes no harassment and the avian species cannot get accustomed to the signal. The proof has come after extensive testing and research in cooperation with The University of Veterinary Medicine, Vienna, Austria and WWF Bulgaria.

After the initial deployment of the system, it operates autonomously, providing real-time remote data monitoring. The database can be accessed for video, data and information retrieval. The collected data can be used for detailed analysis and reporting purposes.

The BCAS software is a modular web-based application that provides access to all functions of the system. It enables fast storage and data retrieval for millions of records.
