What type of WIFI does the doorbell camera use ?
The doorbell camera only supports 2.4GHz WIFI, please make sure you are using 2.4GHz WIFI. If adding a doorbell fails, long press the "Reset" button until you hear a "di" sound, then try to reconnect.
Any installation suggestions?
(1) Installed on a non-metallic door frame about 1.6m from the ground, metal may block the WIFI signal (2) The installation location should be as close to the router as possible to ensure a good WIFI signal
How do I adjust the sensitivity of the motion detection of the video doorbell?
(1) Enter the Smart Life APP(2) Go to the Home interface, click on Intelligent Doorbell, and click on the three dots in the upper right corner "..."(3) Scroll down the page and click "Detection Alarm Settings" > Alarm Sensitivity Level - > set to Low
I don't want to receive non-essential notifications at all, so how do I turn off motion detection?
(1) Enter the Smart Life APP(2) Go to the Home interface, click on Intelligent Doorbell, then click in the lower right corner to expand the function bar, and click Features to disable PIR
Why can the doorbell be removed directly from the bracket?
There is a small screw inside the screw bag that needs to be screwed on after putting the doorbell back in the bracket. In this way, the doorbell cannot be taken out at will.
