An awesome analog option, the BabyCall has wiped out one of the most annoying monitor pet peeves: background noise. Of course, you want to hear if your little one whimpers at 3 a.m., but do you really want to hear his gas (not to mention that weird, alien-invasion noise that tends to come through on inactive monitors)? A voice-activation mode on the BabyCall filters out the constant noises, even background music, and saves the alerts for real baby sounds. The receivers are water-resistant, and there are 27 channels to help you avoid hearing your neighbor's home shopping calls.
