Import Notes About Video Content Analysis
Please take note of the following before you use this module or decide to buy the Video Content Analysis
Edition:
- Video content analysis is a sophisticated technology for the general video security environment. Impath
cannot guarantee the accuracy of the results under field settings. However, the technology promises to
be quite useful and can operate with acceptable accuracy under a controlled environment and with appro-
priate parameter settings. As a result, Impath has chosen to make the Video Content Analysis option
available for the iN7000 system.
- This module should be operating under the following constraints:
1) Cameras must have a fixed field of view.
2) Video signal must be stable – no illumination fluctuations.
3) Lighting must be stable – no flashing or variations.
4) Object reflection (e.g. reflection from glass) may have negative effect on the accuracy.
5) Shadow of objects may have negative effect. Try to tune the angle of your camera to minimize this
effect.
6) Object overlapping may have negative effect. Try to tune the angle of your camera to minimize ob-
ject overlapping.
7) Do not use this module in uncontrolled environment – this module would not work on rainy or snowy
day. If there are trees and leaves, mask those areas.
- The Video Content Analysis module provides advanced features which can be difficult to set up. We re-
commend that those considering using the feature employ the services of professional experienced in-
staller.
