To Moschino re Technomate Hi I am also thinking of purchasing the same to add to my systems, but cannot give u any tech info on your question, however if you go to the site that I am going to give you, they have tons on info on receivers and cams, I have purchased from them and they are reliable, there is also an address where you can ask your question. They have all kinds of cams for technomate.
