These two units come as photographed no other parts, manual, software, connection cables, or accessories are included, please study all photos, as some accessories/parts are not included. I tested these units for basic power up, they power up fine. Two doors opened, manually, the other two are locked, see pics. The system will need to be recalibrated/rebooted and properly setup to gain access using the password, only purchase if you know this system and how to set it up properly. I am providing a solid system, please conduct an online search if you need specific technical specs on this unit, I do not have further internal access. Please contact me if you have any questions or concerns. I appreciate your interest, it's best to know what you are buying, please contact me before purchasing this system.
