Baby monitor: sound or camera?

Alli • Grace 10-8-18 ❤️❤️

So baby will be in our room for the first couple months but then she’ll move into her own room. I would like a monitor even when she sleeps in our room for naps and then of course when she moves to her own room. I also would like to have one with a wireless receiver I could take outside with me (our dog is tiny and gets through the fence so we have to take him out on the leash to go potty). Now my biggest question is if it’s worth getting a camera or just an audio monitor? If it’s a camera, I don’t plan on getting a WiFi one, I don’t wanna risk it getting hacked. But is an audio one sufficient enough? Opinions, experience, suggestions?
