Camera for toddler's room?

mu

My daughter is about to move into her big girl bed in a new room. We will be using her old room, crib and baby monitor for our newborn who is due in a few months.

Does anyone put a camera into their toddler's room? If so which type? What features are important?

I don't like the thought of not being able to check on her or hear her like I can with the baby monitor. I'm a worrier.

Thanks in advance
