Motion detection tuning guide

Motion detection tuning guide

 

ANSWER

Basic settings：
We would suggest customer to configure sensitivity as 80(which is its default value)，designate a detection window，then drag the item size tab to change the minimum size of item to trigger an alarm.
Noted that once the block changes inside the detection window exceed item size value，the motion alarm would be triggered.(As pic shown below)
 
Then we would see the result of false alarm triggering/missing alarm to determine how to adjust the value of sensitivity and object size.
While environmental factors have huge impact on motion detection settings，e.g. the color difference between moving object and background, object movement speed etc，we may not be able to proposed 100% accurate configuration for each customer. 
 

 
 
 
Possible scenario：

• No object passing by motion window，but the motion alarm triggered

Could be video noise, or slight reflection of light resources that could be barely noticed from human eyes.
If the situation happens very often, you can reduce sensitivity.

• No object passing by motion window，but there was a blinking triggers the motion alarm

Could be camera light sensor has sensed that incoming light amount has been changed，so it adjust auto exposure automatically and cause a blink.
 

• There is a tiny object we do not expect it trigger motion alarm but it did

Could be the object size was too small，it is suggested to check the motion block changes in view cell and enlarge object size.
 

• There is an object passing by motion window，but the motion alarm did not trigger

Could be the moving object have similar color as background does，or the object size was too big, it is suggested to check the motion block changes in view cell and reduce object size.
If an object is passing by，but not much motion blocks was lit up，then please enlarge sensitivity.
 

• There is one single object passing by motion window，but the motion alarm did not trigger. Only two or more object passing by would trigger the alarm

Could be the moving object have similar color as background does，or the object size was too big, it is suggested to check the motion block changes in view cell and reduce object size.
 
If you can still not find the most accurate settings，keep missing alarms or triggering false alarm，please provide us：
1. A video clip showing the symptom(which is recorded by VIVOTEK camera itself but not any CMS so the video would not get distorted during transcode)
2. The description of symptom and its time period/duration
3. The configuration file exported from camera
 
We would recommend proper motion settings which could fit your requirement.
