So I don't know anything about wireless frequency and how the pair together so I just know that's what it says on the back of my camera. I have a uniden udw20553 wireless camera setup with monitors that doesn't have a way to record just view. I wanted to know how I can get a monitor that I can record to an sd card but still be able to view from my home to see what is going on around my home while I am inside. (mainly kids outside playing on my porch) And I would like the ability to maybe view it on the iPhone while at home or away. Is there another monitor I could get to pair with my cameras as well as do what I would like to do with an app on my phone. Or a dvr system I can hook up to my camera's that will connect to a tv. I mean how can I get something to receive the signal from these cameras I already have? I have had this system for a while and haven't used it.
