Go into the Dahua sub-forum here and look at the owner review threads for the various Starlight models. If you’re going to be recording in low-light conditions (like outside at night), they’re about the best cameras for the dollar. Also check out the “Cliff Notes” document, which is located in the Wiki (a link on the blue forum bar at the top of this page).

You are the right place for such a question, but not exactly the correct forum. You should ask this question in the Hardware->"NVR's, DVR's & Computers" forum.
