The Smartwares Video Door Viewer enhances your security against trick thefts and unwanted visitors. Check who is at the door before you open it. The large, comfortable screen is especially suitable for glasses wearers, children, the elderly, and people with disabilities such as dwarfism or wheelchair users. The built-in recording function allows for photo or video capture at the push of a button (microSD card included). The device does not require an external power supply and operates completely independently. An integrated calendar function lets you check important appointments before leaving the house. It is also suitable for hotels, guesthouses, vacation rentals, and motels.
