Great picture quality - audio issues

This camera has great picture quality even in the dark. I bought this to keep an eye on my daughter playing downstairs while I cook or clean upstairs. I liked this specific camera because I could communicate with her but there is such a long lag after I finish talking before there is audio again that I miss her response every time. I can see her mouth moving but there is no audio for 5-10 seconds. It's super annoying.
