We have recently purchased C230 for better resolution to capture birds on our bird feeder. We were previously using C100 for this purpose without any issue. Unfortunately, C230 is not detecting any birds while our C100 in the same exact location and same settings detects  and records movements of birds as expected. 

Both of them are detecting humans and large object movements. 

We have put the sensitivity to maximum and C230 still does not detect birds. 

It appears that Tapo C230 has issues detecting movements of small objects like birds but can detect larger objects (humans). Is this a known issue with C230? Is there any solution or workaround this problem? 

Thanks.
