Some notes about the VTO2111D-WP in use as a doorbell cam:
Only works on local, there is no cloud service when you are not home
Video and audio work fine on iDMSS app
720p video is good for confined spaces
Wish I could set my cam as a default view for devices in the app, each time you launch the iDMSS app you need to select the cam even if you only have one Dahua camera on the network
It works in blurIris as an RTSP stream
Blueiris will capture motion and issue alerts
Audio does not work within BI at all as of now (maybe I could work with the BI programmer if I re-up my support contract?)
I am using BI motion alerts when I'm away from the home to let me know someone is there whether they depress the doorbell or not, so I can launch my VPN and look/talk
I am using an always-on iPad (wall mount for home automation) with a BT speaker connected to it for a 'chime' whenever the button is pressed
In the future I am hoping to use the provided pigtail of leads to actuate a NO/NC contact zwave sensor so i can get alerts through my HA software but having trouble getting that to work without hacking the camera or frying it too bad
