Their customer service was fabulous and their product is one they stand behind

But overall, we would buy this again! Love the night vision

To get into VOX mode you need to push the two top side buttons at the same time (left brightness +,and right volume + )and it will turn VOX on or off

We do find it a tad bit creepy that if you turn off the monitor while the baby is crying (we are quick to turn it off if we aren't using it so it doesn't interfere with out Wifi)when you turn it on the next time about a half a second of that previous audio/cry will come through

Battery life is eh, but expected for the features

Thankfully we have a dual band router and could easily switch our devices to the 5GHz band to eliminate the interference
