Which doorbell camera suits your situation

This page does not rank cameras. The right one is decided mostly by your door, your wiring and your lease, and those five facts eliminate most of the market before any review matters.

Do you own the place, or rent it?

Renting pushes you hard toward battery power and a reversible mount, because wiring and drilling are the two things a lease is most likely to restrict. This one question removes more of the market than the other four together.

Is there existing doorbell wiring, and what is it rated?

If there is, check the transformer against your model's requirement before buying. If there is not, you are choosing a battery model whether or not you wanted to.

What is the wall made of?

Brick, stucco and vinyl siding each rule out mounts that work fine on smooth painted wood. Decide the mount at the same time as the camera; discovering the mismatch afterwards is how a camera ends up crooked.

How is the Wi-Fi at the door itself?

Not at your phone on the porch, at the door. If it is marginal, either fix that first or choose a camera that stores locally and does not depend on a live connection.

Do you want a monthly fee?

Subscription-free cameras are a real and well-populated category. Going without a plan usually means local storage, and sometimes means losing features the marketing implied were included.
