These are standard definition cameras commonly used for FPV R/C flying. The only thing they'd be good for with rockets is live transmission of standard definition video to a ground station via, preferably, a 5.8GHz link with a 600mW TX at the camera end and a high gain directional antenna at the ground station which would consist of a 5.8GHz RX, a daylight readable/shaded LCD display, and, optionally, a DVR capability as found in some LCD displays intended for FPV use or via a stand alone mini DVR made for the same purpose or via a USB analog video digitizer into a laptop.
