Would this monitor work from one house to another, across a street.
Answered by VTech_SupportHello, The maximum operating range of this VTech DM221-2 Baby Monitor is roughly 1000 feet outdoors, and 160 feet indoors. The actual operating range depends on environmental conditions, as well as any interference from outside sources. Thank you!
I am very hearing impaired. Does this also vibrate?
Answered by VTech_SupportLin - Yes, the VTech DM221 has vibration alert. The parent unit will vibrate whenever the baby unit detects loud sounds. Thank you for your interest! ~VTech Support
I purchased an additional parental unit (DM221) but cannot get it to link.
Answered by VTech_SupportJudy - We are sorry but the VTech DM221-2 is a non-expandable baby monitor. You cannot pair or add another parent unit on the system. Thank you! ~VTech Support
Can you add more receivers to this
Answered by VTech_SupportAdditional Parent Units cannot be added to the DM221-2.
how far of a distance will they reach
Answered by MomsCareGiverI live in a duplex- each side about 950 sq ft. I can clearly hear my Mother’s activities in her bedroom and living room. I can holler at her just to make sure she is ok and she can hear me throughout her house. I am super impressed!
