theerzengel 0 Posted April 22, 2011 Hi, I'm interested in buying the Samsung 3000N Video Recorder SDE but I have some questions you might want to respond to me. Of the 4 cameras you can buy these have the option to record audio? How long the security video recording? How often will require a USB backup by noon? Sorry my English is not so right.
