Unfortunately you can't edit the questions :-( With this camera it's the other way round, in the specifications it says mains operation but in the description battery?!?! https://www.digitec.ch/de/s1/product/deltaco-sh-ipc09-1920-x-1080-pixels-netzwerkkamera-21466106 I need a simple outdoor camera with wifi and battery operation (it is also important that you can limit the zones of the recording, both would fulfil this).
