I fail to see the relation between a video doorbell and stopping a burglar. Burglars wear masks.

Also, a doorbell ringing on the outside of the door is not only silly but in case of an apartment complex highly annoying for your neighbors.

And make sure your neighbors like being monitored through your five services.

Personally I have a button outside my front door. It is connected with a copper wire to the other side of the door to a small device that sends out an audible notification. No cloud required.
