IVS - Intelligent Video Surveillance
About
The Face Capture, Perimeter Protection, and IVS functions cannot be used at the same time, only one Analytics+ or IVS function can be used at a time. In addition, the Smart H.265+ and the Smart H.264+ cannot be used simultaneously with either an Analytics+ or an IVS feature.
- After smart codec is enabled, the device would stop supporting the third bit stream, ROI, and smart event detection, and the actual interface shall prevail.
- The "Loitering Detection" IVS rule is present on several Dahua North America devices at this time. However, this feature does not currently work, and is not advertised as a feature in any of the spec sheets.
Setup Suggestions
- The target should be less than 10% of the image.
- The target size in the image should not be less than 50×50 pixels.
- Brightness difference between the target and the background should not be less than 10 greyscale.
- The target should be continuously present in the image for no less than two seconds, and Event 134 the moving distance of the target should be larger than its width and no less than 15 pixels (CIF image).
- Reduce the complexity of surveillance scene as possible as you can. Intelligent analysis function is not recommended to be used in scene with dense targets and frequent illumination change.
- Avoid areas such as glass, reflective ground, water surface, and areas interfered by branch, shadow and mosquito. Avoid backlight scene and direct light.
