No matter where you are, with the free smartphone app VISTASMART2, you can see, hear, speak to your visitors, and even open the door from anywhere. The connection to the router can be made via Wi-Fi or the included LAN cable. When a visitor rings the bell, you will receive a sound and push notification on your smartphone. If a microSD card is inserted, a short video clip will also be recorded. This way, you can see later who was at your door. The camera can also be activated via the integrated motion sensor (individually adjustable). Photo and video recordings are possible during the conversation as well. The door can be opened using a slider to prevent accidental operation (if a door opener is available). Click & Easy Installation – simple wiring of the system at the back housing. LED downlight for step and entrance lighting: On/Off controlled by a light sensor (selectable). The automatic, even white LED lighting of the doorbell button turns on automatically in darkness and off in brightness.
