Panasonic VS-HC400-W Home Network System (Door Camera with Monitor) White This is a gift, but I'm selling it because I don't use it. I opened it once to take pictures. ● [Door Camera] Easy installation by hanging on the front door *1 Wireless connection, so no wiring is required. Installation is as simple as hanging the door camera on the front door and securing it with the included hex wrench. No troublesome construction work is required, and you can start using it immediately from that day. ● [Chime Link] Automatically displays the screen when the chime rings *2 When your home's chime rings, it detects the sound and automatically displays the visitor on the screen. *Chime Link only works when installed on the charging base.
