This is a monitor camera for a Panasonic door. I purchased it for security because my intercom didn't have a monitor camera. I think I used it for about 6 years. I am selling it because I no longer need it after moving to a new place that has a monitor camera. It requires 4 AA batteries, but batteries are not included, so please prepare them yourself. I tested it before listing, and it worked without any problems. There is no box, so I will ship it in a recycled box. - Brand: Panasonic - Model: VL-SDM110 - Color: Blue - Accessories: Instruction manual - Function: Wireless monitor function - Power supply: AC100V 50/60Hz #SecurityCamera #MonitorCamera #CameraMonitor #DoorCamera #DoorPhone #Intercom
