Positive highlight:
+ No interference with WiFi, mobile phones etc., and we have several devices permanently on the net with high-speed DSL Unitymedia
+ Good image quality
+ Temperature display
+ Super reception over several floors with thick blankets incl. Underfloor heating
+ Super easy and intuitive operation
Minor points, which are not relevant for us:
- Voice quality of parents to child miserable, but we did not use anyway
- When operating with 2 cameras is always "react" to only one, you have to switch so always. We also do not benefit. Simply pick us at the 2nd child for the great price a 2nd set.
Everything all an absolute buy recommendation!
UPDATE 04/14/2015
Unfortunately, I have to deduct a star, because the device a very unpleasant for us, "Macke" has: If the receiver battery is empty, the device goes just made. No warning beforehand and you can see it only because the tiny green LED is now off. Is very very stupid if you fall asleep on the sofa, for example, while watching TV, the thing goes out and you will then eventually awake because you can hear the child screaming through 2 doors, one floor and the noise from the TV. Not nice !!! When you consider that the part of Red Alert suggests when the transmitter is out of range (which is a good thing), it would have been easy to implement this feature for the situation "low battery". Or?
We now always make sure that the receiver is in situations where we are not as attentive in the charging station.
