This is the Panasonic wireless TV doorphone "VL-SDM310-W". It comes as a set with a main monitor unit and an entrance unit, and can be installed without wiring. I am selling it because it did not suit my home. The LCD display, calls, and recording/playback functions have all been tested and confirmed to be working. All accessories are included. The warranty card is blank. Please refrain from purchasing if you are sensitive to used items. To prevent product substitution, I have taken photos of the serial number. I am selling it because I no longer have the opportunity to use it. *Please refrain from purchasing if you are sensitive to used items. I will carefully pack and ship it.
