Abstract:
The paper deals with the methods of security implementation in community areas based on certain high technology sensor system and communication methods. Security systems for home or industry have a lot to perform today in terms of reliability and performance. After examining the various modes for security management, the paper describes data collection and fusion which demand careful processing and discerning of the security problem. Herein, the problem of data detection without errors becomes important to avoid falsely discerning insecurity levels. This paper examines some signal management methods for error free operation of signals from Doppler motion sensors and camera image data. Amongst them this is considered the technique for encoding data using the Hilbert Transform. This is better for motion sensors with a few extra bits of transmission enabling error free reception at the monitoring computer station. Also considered are wavelet compression and transmission for remote site image data using spread spectrum.
