Resumo:
The current interest in protection of private property against trangressors and onlookers has increased the demand for better surveillance systems. This work describes a wireless video transmission system for surveillance purposes that is more practical, agile, dynamic, and secure than traditional ones by using Bluetooth technology, with a wireless self configurable network, together with MPEG-4 video encoding, with extra protection and high compression rates. Results acquired from simulation using the Ptolemy environment are presented showing how the system behaves when a server transmits videos varying packet size and type, frame rate and the client buffer size. These results show our system’s advantages and viability. Research about the three technologies involved in this work is also presented: Bluetooth networks, MPEG-4 encoding and Ptolemy modeling framework.
