These cables were removed from buses in 2023 when the school district upgraded their DVR systems. They were working when removed. We have sold many other cables, wiring harnesses, cameras, and DVRs from these systems without any issues with functionality. We have several various cameras, DVRs, and cables also available. If you are looking for a particular Seon cable or camera, please let us know, we may have it and have not listed it yet. Please see attached pictures.
