After problems review adjusted!,

I bought the kit to monitor my front door.
Commissioning was no problem. Unpack, plug together, running.
The radio range is very large at me cross durch`s house.
The resolution of the Cam is sufficient for the small 3.5 "monitor.
The radio range is very large at me cross durch`s house.

Disadvantage of the system is the relatively narrow viewing angles, and above all the constantly in the dark
smoldering IR LEDs and diodes for the indicator. This makes the Cam really striking.
A not to be underestimated and nowhere described fact is, however, a lack of
Wall mounting option for your monitor! That is sometimes just next to the front door screws on the wall
it does not work! Instead, a support bracket is available as a picture frame.
That's really stupid and not to be expected, since an explicit doorstep monitoring is advertised
and an inner mounting possibility of the monitor next to the front door but should be standard.
Because of the described disadvantages, there are 2 star deduction

Note also the cam and monitor each one 220V - supply for the two power supply units need
the appliance plug side are of different sizes.
Due to the very simple commissioning through the wireless connection of devices and good function, it is "my" solution.

Addendum: Due to constant crashes and far more visible LEDs in the dark I returned everything.
