A:AnswerThis kit comes with a 1 terabyte hard drive. There are various factors that can determine how long it will take to fill up the hard drive (before it starts recording over previous footage) but in general, roughly 30 days. You can change the settings in the DVR to "intelligent recording" and it will only record when motion is detected.
A:AnswerNo. But you can insert a USB drive into the back of the DVR and back up the footage that way, or then take the USB drive and plug it into your computer.
A:AnswerYou can use any surveillance cameras that have a BNC connection on them with this kit. We do not sell the individual cameras through Best Buy, however if you do want more Zmodo cameras, the 4 pack you would want is ZMD-P4-YARUZ4ZN.
