 Perimeter Protection 
Perimeter Protection Dahua Analytics+ includes Tripwire and Intrusion functions that offer 
custom tripwires based on object type for automation in limited access areas. Perimeter 
Protection requires less pixels to detect an object to deliver improved accuracy and decreased 
false alarms due to lights, weather, trees, or animals. 
6.2.1 Perimeter Protection Guidelines 
  Video resolution should be 1080p or higher. 
  The target height should be smaller than 2/3 of the image height. 
  The brightness difference of the target and the background should be no less than 10 gray 
levels. 
  Draw the tripwire line vertical to the direction the target is moving as much as possible. 
Avoid drawing curved lines; these lines may cause detection failure.
