Limiting adding point to only within specified distance

[yockee]

How do I limit the addition of point using Collection Settings in Field Map ?

I want to be able to collect point to only within specified distance from the target. I have tried and find out that  The Accuracy setting can not limit the  collection to within specified distance, it only gives out warning but does not prevent the actual addition of point.

I also use Web App -> App Settings -> Use GPS Location enabled (see the second picture). This does not have any effect as well. I have checked the coordinate does not reflect the current location where I am standing at.

thanks
