NO instructions in the box, not even a Q-Code. I am using this with Zone Minder so I am sure it will see it. One of the cameras had something rattling inside, opened the cover plate and speaker is not connected. It will a total PITA to take this thing apart to seat it and glue it in place. Other than that it appears to be pretty solid. I saw a silica packet taped to the inside chassis behind the PCB, wow.
camera quality is amazing. brilliant technology and features.
