The camera is housed in a small housing, which is fixed by ball joint to a support. The ball joint is made of metal and holds the direction in which it was switched on and determined. The support can then be fastened with screws to wall / ceiling, etc..
The WLAN features could be better and can be improved (in YouTube there instructions,) by their own initiative.
Interestingly, the camera uses for the LAN and the WLAN interface the same MAC address; you can not use both interfaces at the same time so. WLAN uses the camera obviously only if it considers LAN as not going. (Power on again interrupting power;; LAN cable in / out) To change it, you have to restart the camera.
I have the camera out of the "used" bought deal and have not been disappointed: everything like new, only an existing registration of the camera with D-Link (for remote access) still existed, but which can be easily replaced and also should (otherwise Possible the previous owner to access the camera).
