What is in the description of the article is not clear and which is probably one or the other buyers do not seem to understand is this:
The baby monitors severs the connection between the base in the nursery (transmitter) and the parent (receiver), if any noises in the vicinity of the transmitter. This means that the flashing light on the receiver that indicates a connection is not available, it means basically once nothing. Because once in the nursery sounds (for example, a call of the child) can be heard (on the transmitter), the device establishes a connection between the base and parent and in a maximum of 8 seconds, the child is free from noise to hear. This function of the low-radiation monitoring can be had also shut down, so that a continuous wireless connection exists and no time elapses until the digital connection is established.
So let's summarize:
Positive
+ Excellent voice quality
+ High ranges (up to 300 meters [manufacturer's specification])
+ Good price
+ Low-radiation
+ Continuous connection switched
Negative
- Maximum volume a little too quiet
So not just throw in the towel when permanent disconnections are displayed. These terminations show but only that in the nursery everything is fine. And where no connection, since no unnecessary radiation exposure.
