Awesome, affordable baby monitor?

Katie🐬
I need a baby monitor. I thought I would be okay not needing one but we live in a 3 story house. And I can't leave her door open because we have 11 animals that I don't want in there. 
I want one with a camera so I can see her. I don't want it to be a wifi one or be connected to my phone. 
So, which one should I get? There are so many to choose from.
