Video surveillance systems

Intelligent Motion Detection

Motion detection is not a new function, but some of the current systems generate false alarms because of movement from trees, water, falling leaves, etc. The manufacturers always strive to find better solutions for eliminating such false alarms and one of the newest is the intelligent motion detection by SONY -- IMD.

In most cases with other manufacturers, the motion detection is done by comparing 2 frames, while SONY’s system compares 15 frames using a complex algorithm, before compressing the video signal. The end result is less false alarms.
