Common experience (mine included) with relatively inexpensive quality wireless analog cameras is that there seems to be no such thing. Much better to run wires, especially considering that you have to get a power wire to the cameras somehow. There are good reasons to go wireless between buildings, but you'd most likely be happier using wifi and network IP cameras than analog gear. As for smartphone viewing, just about every system nowadays supports Android phones.
I suppose I was thinking wireless because it seemed like easiest installation. Wires through walls and all that seems like a headache, I would definitely need to hire someone to install it. Do you have any brand or model recommendations for cameras or DVRs? Should I go with an all-in-one package or buy my cameras and DVR separate? Thanks for responding!
