Here is a video of how ZKTeco TL800 works
TL800 is designed as a fully automatic smart lock with a built-in indoor monitoring screen. It could unlock and lock the door itself. It is compatible with USmart Go, an application designed for home automation. Users could enjoy remote control and online real-time monitoring when connecting the intelligent lock to the Wi-Fi network. What’s more, the owner could observe the outdoor situation from the OLED screen installed inside the house.
