What I would like to know is, does anyone make a small portable universal monitor for use in the house so I don't have to use my phone? It would have to work with all brands as I have one pointing my mailbox/frontdoor to watch for packages and another brand to watch my dogs lose their minds out back in this massive backyard I have now. They love it but I like to see them fly by the cam so I know there ok. Or can I build one? Thanks yous guyses!
