We wanted the baby monitor for a permanent night surveillance use as our BEDROOM not within earshot of the children's room is located. (120sqm apartment building with thick walls) And that is the weak point.
The MBP 8 is not (Baby) and receiver suitable for large distances between stations. Losing the baby monitor even when the doors open its contact so you will hear a beep. So far so good, however, it loses this contact also like 2:30 to 3:00 clock in the morning with no change of position or apparent reason. The success: Parents are awake and trying to make viable again the baby monitor. The child sleeps on. For a permanent monitoring definitely not suitable.
