The system works about as well/ as badly as all other systems. "Max. 300m" is probably in the open, in an apartment/ from flat to apartment/ house to house/ flat to garden/ 1st floor in the basement you can simply forget 300m. The positive thing about it is: If the direct connection doesn't work, you can use the WLAN/Internet on any Internet-capable mobile phone. However, this communication must always go via the Motorola server. How secure this is is questionable, but I don't think any hacker is interested in a sleeping baby. DECT: Someone posted here that it works without WLAN with DECT. I don't know myself. -> ask google. All in all a good device. In terms of the whole touch-and-feel, if you don't need Wi-Fi, I would recommend the NUK ECO Control+Video 2.4 GHz baby monitor. A very good device, but without Wi-Fi and without a recording function.

Must specify: apparently devices from Motoroal of this type, as they all use a similar camera and the same web technology.

Yes there are 5 different melodies that can be played. However, the volume of the melodies cannot be changed, so it is rather unusable. However, the device is really recommendable! We have been using it for 10 months now and are very satisfied with it. Top video quality compared to other systems.

The camera can be controlled with the local network via app. If this is not desired, the camera and the screen can be transmitted "normally" via DECT signal. WiFi is therefore not absolutely necessary.
