I need help please with a friends cctv set up as i dont have any idea. She wants to view it from her phone.She does not have wifi.A neighbour has said she can use there wifi.The neighbour has a outside wifi booster aerial,But the neighbour house is 250ft away if she does manage to use his wifi will the neighbour be able to view from his phone.If so maybe its not a good idea her using his wifi.So what is the best way for my friend to be able to view from her phone.Could she have a her own wifi connected what will she need.There is a BT phone line close by.She does not want a BT phone.Any idea what the cost of wifi would be as she is on a low income.There are no other phone lines apart from BT
