Question: how is the audio quality?
Document: The infrared lights are barely noticeable when on, and do not disturb our son at all  The infrared image quality is a bit worse than with full light, but that's to be expected. We don't use the audio most of the time, but it seems to work fine. You can record video/audio using the iPad app but not through the website. I have had only one issue with it so far:  the iPad app (actually its and iPhone app... lower resolution) occasionally crashes on me.
Pros:- ease of setup was nice & excellent software. Stream from your smart phone!! !- motion detection- excellent for streaming day or night (night vision) + audio- inexpensive & aesthetically pleasing.Cons:-limited length of power cord (easily fixed with an extentsion cord)-no zoom (nitpicking, i know. )For the price. You can't beat the quality of this camera. Fits my needs of monitoring my baby's room and/or my backyard where my dog roams.
However, you can turn them off but you won't have very good night vision.Third, you can record the camera images and audio right to your phone (which I do).Finally, I had it up in running with my Android smart phone in about 10 minutes.
You can also listen to audio but only in the live feed not through the recorded images. The only issue is that through a cell phone network it did take forever to load...but through wireless it is always fine. I kind of want to put them all over my house.
This is the WORST product I've ever purchased from Amazon! Constant issues; feed drops and audio skips had to resign in constantly. Absolutely horrible. I'm shocked at the rave reviews (which is why i purchased in the first place). This product is one headache after another.
This is an amazing cam. I use it daily to watch my 2 year old in her crib. It has an automatic dark/light detection and it looks great in the dark. The audio is good on my computer and android but on my Ipod touch its not as good. I recommend this cam to anyone.
This camera is great! I had read that it wasn't very good from some of the other reviews but decided to go ahead and get it anyway to use as a nanny cam and it's pretty awesome! Great picture and the audio is also pretty good! I had a little trouble with the set up but I emailed the customer support and they responded almost immediately and fixed my problem!
This camera was very easy to setup. The software is going  thru upgrades, but currently what works is great. You get motion detection recording which can be viewed on either the iphone and android platform.The pros:- very easy setup- good software- motion detection recording- real time video- night vision (upto about 5ft)- audio (in real time video only)the cons:- the field of vision is good only upto about 5ft.
So it is good for simplicity but the quality could be better.
Overall I am very pleased with the price and quality for the price and ease of use.
Answer: I've turned the audio on a few times and it was fine.  I like that it doesn't have to be on all the time.  I could easily hear the TV in the background even though the TV was on low.
