I agree that the Infant Optics monitor is great. Totally foolproof, decent range (unless you have concrete walls) and much lower latency than any of the internet connected devices I have seen. I also recommend Phillip's line of audio only monitors. They are even lower latency and have an excellent filtering algorithm built in. I can play lullaby at a decent volume and it won't let any audio through, but as soon as baby makes a tiny noise the audio comes through clearly (including the music of course). It saves a bit of mental load from listening to baby music all the time.
