Any advice on outdoor camera/ surveillance system? Would like to have remote access with app/iPhone and ability to have set programs that will record if motion is detected etc.. And of course night vision. The one ADT showed me this morning offers all these things but has to be plugged into an outlet- do all outdoor cameras require a power source? I understand the rest of the system is wireless but the mandatory power source is a potential wiring issue. I was looking into Nest also but it looks like they only offer indoor cameras which I will probably do in addition to the outdoor cameras. Help!! Any recommendations or advice much appreciated! Thanks in advance!
