Yes you would still need a recording device as this is only an "imager". Here is a statement from their site about compatible recording devices:
Camcorder Compatibility
NOTE: Only camcorders with video inputs are eligable devices for use with the "TrophyShot"-"Imager".
To test if your camcorder is compatible with our system, connect your camcorder to a TV or VCR and try to record a program onto your camcorder. If you can record onto your camcorder from another device such as a TV or VCR through the RCA jacks, then your camcorder is compatible.
The following is a list of camcorders that have the required video inputs for compatability with the "Trophy Shot"-"Imager". This list is fairly accurate, but if you discover a model that we have on our list that does not have video inputs, please let us know so we can remove it.
Use this list as a helpful guide, but make sure to try the above test to be sure that your camcorder is compatible.
