Now for the good stuff:
If all 4 cameras record and existing 1TB HDD can be recorded continuously for nine days ca. If the disk is full, the old simply overwritten (this is adjusted automatically and can also be austestellt).
In the setup of the receiver you have to see only cope, but this already then comes with time.
The quality of the cameras is quite good. People can thus be already identified.
By means of motion of the cameras can also be set so that you get a photo e-mail, when something moves - but it is not easy to adjust (I still have not try)
The 20m cable length was too short and therefore have not purchased additional 10m cable with adapter - and I did not get a loss of signals.
