Need a new baby monitor

My levana fell and is malfunctioning and levana said they can't help me. I'm looking at buying 2 wifi cameras so we can use our phones as monitors. We have a friend that can encrypt our network so I'm not worried about hackers seeing them. Does anyone use these wifi cameras and have a suggestion on one? I need one for my toddler and one for the new baby due in january. Just looking for personal recs.
