General IVS Setup Recommendations

Below are steps you can take to ensure your IVS rule setup is optimized:

• Reduce the complexity of the target area as much as possible. No more than 50 objects should be in the camera view (cars and humans).
• If IVS rules are setup on a channel, make sure motion detect/ Intelligent motion detect is disabled on that channel, as having both IVS rules and motion detect enabled on the same channel have been known to cause issues. 
• Avoid target areas such with glass, reflective surfaces, water surfaces, heavily wooded locations as well as Insects flying close to the camera lens as these can generate false positive alerts. 
• Target areas with a dense amount of target objects is not recommended.
• Target areas should avoid heavy backlit, direct light and locations with frequent illumination changes (shadows, etc).
• Disable Intellistreaming if enabled. Intellistreaming disables features such as IVS rules.
• The recommended target size should be less than 10% of the overall image. 
• The minimum recommended target size is 50×50 pixels or 80x80 pixels if using a camera with human/ vehicle filtering.
• The target object should be continuously present within the frame for at least two seconds.
• The target object and the background brightness difference should not be less than 10 greyscale.
