Best baby monitor for 2 or more kids

Cherie
I'm due in July and looking for a monitor I can use for both kids. My oldest just turned 19 months and transitioned to a big girl bed. I need to be able to tilt/pan/zoom the monitor to make sure she is not getting into trouble in her room. But I also want to be able to see the little one. Any suggestions, no price point. Just need something that is good!
