This is a set of Panasonic TV doorphone master and sub units. The entrance unit is broken and cannot be used. (The lens has deteriorated and the image is not clear. No sound comes from the sub unit.) The audio from the sub unit could be heard on the master unit. The image was also visible, although unclear. The master unit was working normally until it was removed, but its future operation is not guaranteed. Also, not all functions have been checked. Therefore, this item is being sold as junk. If you wish, the broken sub unit can be included as a non-functional junk bonus. Please let me know via message. If there is no request, it will not be included. Please note that there may be oversights or misunderstandings due to my amateur assessment. If there is a discrepancy between the photos and the description, the photos will take precedence. Please understand this beforehand. Everything in the photos is included. Some necessary parts may be missing. Please examine the photos carefully and make your own judgment. Please refrain from purchasing if you do not understand the nature of junk items or if you are looking for a complete product. No claims and no returns are accepted. Model: Master unit - WQD1223W Sub unit - WQD1263W Functions: Recording/playback, monitoring, calling and communication between master and sub units (Please refer to the manufacturer's website or the internet for details.)
