Hi Rafale
I don’t have an NVR yet. I just put a 128GB SD card in to the Ezviz DB1 so I don’t have to pay for cloud storage.
I plan eventually to get a Hikvision POE NVR and more Hikvision cameras.
I have managed to integrate the DB1 camera in to my Kodi HTPCs using its RTSP stream. I also installed a free Cam app on my Amazon Fire TV stick and used its RTSP stream also.
Vera only supports http mjpg or jpg snapshot URLs as does Imerpihome app seemingly, as I cannot get RTSP streams working in Imperihome at all.
As you problably know the Ezviz DB1 out of the box, does not support Onvif or mjpg or jpg snapshots with the Ezviz firmware.
I think you can flash them with Laview firmware to get Onvif and jpg but then you lose Google Home integration.
So I setup TinyCam Pro on my wall mounted Android tablet that normally runs Imperihome.
Using the TinyCam web server function I now am able to get mjpg and jpg URLs which I have used to add the camera to Vera and Imperihome app etc.
This seems to be working OK so far.
But what I don’t know how to do, is how to send http json commands to Vera upon motion detection on the DB1 camera.
Perhaps TinyCam can do it or maybe with Tasker also.
I’m not sure yet I haven’t got that far and worked it out.
