Unfortunately only worked 12 hours in WLAN mode. Unfortunately opened package and incomplete

Unfortunately initially missing from the package components that need to be loud in there package: CD, warranty card, screws for mounting the camera on the camera base and the Installation Guide. The package was not sealed ...
Most can be found on the net, just not the warranty card, so I installed 3 hours. Delivery after absolutely gorgeous with Wi-Fi, but ---- only just 12 hours.
The next morning, the WiFi was no longer to activate. With LAN port after reset everything was indeed again adjustable- alone, the part does not transmit a wireless signal from more and - found after separation from the LAN either of the FRITZ still own search program, no IP.
After calling Amazon immediately a replacement unit was set in motion. Let's see how it goes!
