My pleasure. Look forward to working with you next time!

We sorry for your comment and regret that you didn't contact me to communicate detailed questions during the test. 1, network disconnect ----- this device is more strict on network quality, are you testing in a stable network environment 2，many calls miss without notification----App notification feature is turned on? 3，no option to add cards or add password from mobile app-----This is a Video intercom&Access, you can intercom and open the door remotely through the app, and the password can be passed to the visitor in other ways. Looking forward to your reply and communicate with you more!
