Hello guys. Last week I'm install the system VTO2000A + Vth1660ch something strange happend. I think the reason is when I changed the default vto unit password from "admin" to custom password.after that The camera stop working from the monitor. And the unlock button changed the appearance and not respond to click button to open electric lock. The electric button Can use only from the gdmss application. Somebody know this situation and can give solution? also the gdmss app not respond when someone call in vto outside I use at last version. Gdmss+ for android. Push notification not working.
