Does anyone have a recommendation on a monitor that can go a long distance? I'm not talking miles or anything, just farther than my Motorola.

I'm 100% fine with just audio. Think baby inside house (second floor) and you outside working in the yard.

I've tried googling this and everyone seems to have different thoughts. According to google, the range specified usually isn't accurate and is based on an open field. This may come as a shock, but my house has walls, etc.

Thanks!
