i do not have a iphone, but i guess all the smart phones are the same.
in my android app , "meyepro" i think you can get the same name program for the iphone.
what you need to type in.....
device name
url address
mobile port
user name
password
max channel
the url address and the mobile port are the only ones that may need explaining....
unless you have a static ip address, you need to use a company like "dyndns" that will allways point to your ip address no matter what it is.
the mobile port is the same port that you have open for the "DVR"
i think that should cover it for you.
