VTech DM111 Safe & Sound Digital Audio Baby Monitor With One Parent Unit

Parent units need two AAA alkaline batteries (not included). Works best with Polaroid AAA batteries. This configuration includes one parent unit (monitor) and one baby unit (audio monitor)
DECT 6.0 provides crystal clear transmission, eliminating the annoying white noise you hear from analog monitors
5-level sound indicator – graphic bars on the parent unit indicate the level of sound in your baby’s room so you can visually monitor the noise level with the unit muted
