Perimeter
Description
Perimeter protection: with deep learning algorithm, Dahua Perimeter Protection technology can recognize human and vehicle accurately. In restricted area (such as pedestrian area and vehicle area), the false alarms of intelligent detection based on target type (such as tripwire, intrusion) are largely reduced.
Installation Suggestions
- The target cannot exceed 2/3 of the height and 2/3 of the width of the image
- Draw the cross line vertical to the moving direction of detected target as much as possible
The installation site and installation type are essential to the final performance, this section introduces how to select a proper installation site and installation type
Suitable Sites
The sites need to provide a large visual field and be open and simple. There should be no frequently moving objects or drastic changes in lighting condition.
These kind of sites are suitable for cross detection at borderlines, communities, lawns, railways, and highways, access detection at underground garages, pedestrian streets, fall detection at lakes, and access detection at rooftops and private properties
Configure a intrusion rule along obvious perimeters, such as a plants/trees.
Configure a intrusion rule along obvious perimeters, such as lawns and lakes.
Install cameras at a high position perpendicular to the road to monitor humans and vehicles.
Install cameras at park or garage entrances to detect humans who goes into the motorway or vehicles which goes into a pedestrian area
Configure tripwire rules at store entrances.
Unsuitable Sites
Large obstacles around the target area that blocked target objects.
Vehicle headlights on the road makes drastic changes of lighting condition, which influences detection performance
The ambient light is too dark, and cameras have poor performance under black and white mode.
Installation Requirements
The shorter the installation distance is, the smaller the arm width will be
The maximum arm width for humans is 12m
Fixed Lens installation distance reference table:
| Lens' focal length (mm) | 2.8 | 3.6 | 6.0 | 8.0 | 12 | 30 |
| Installing distance (m) | 6 | 8 | 13 | 17 | 26 | 65 |
Varifocal Lens installation distance reference:
- When the install distance is 5m~22 m, it is recommended to select the lens which focal length is 2.7mm~13.5 mm.
- When the installing distance is 13m~55m, it is recommended to select the lens which focal length is 7mm~35mm
- Recommended installing height: h > 3m and the maximum height varies with different lens
- Recommended installation angle: 0° ~ 45° (elevation angle)
- Recommended lens: Low focal length and large angle of view
