Ask HN: What feature rich, secure puppy cams are you using?

I just got a puppy and I'd love to keep my eye on her while I'm away to make sure she's not howling at the neighbors all day.

The puppy cam market seems saturated and based on a few blogs I've read there are quite a few cams with gaping security holes.

Some features I'm interested in are 2-way audio and controllable camera. Saw some that offered treat dispensing, but not sure if that's a necessity!

I'm curious what cameras is HN using and any security tips you have when setting them up!
