I have used this system for a few years and it works perfectly and includes everything pictured. You get the main unit, (5) door sensors, (2) tags, original boxes, misc hardware, and a bonus in wall holder.
So if you want to mount this inside the wall you can do it with this accessory. Tape from the originals has been removed but there should be enough backups in the misc hardware. Everything is used and in good condition and everything works perfectly. Google Nest Secure Alarm Security System Nest Guard (5) Detect Sensors (2) Tags.
