Hi, Looking for a bit of help if you don't mind! Once I have set this camera up on my network would it be possible to reposition the unit in a house that doesn't have the internet having previously set it up to record direct onto an SD card. I need to record some activity at my 90 year old relative's and they dont have the web. I believe it can record about 24 hrs on a SD card and then replay it back on my laptop? Thanks
