  • @Monocle The Amcrest ViewPro App (for Apple and Android) has the option of looking at the matrix view (all the cameras being recorded by the NVR in one grid view).

    It calls the camera view Channel 0-0 and Channel 0-1.

    I’m trying to come up with the rtsp:// syntax to use this camera stream with Monocle.

    rtsp://192.168.1.240:554/cam/realmonitor?channel=0&subtype=0 doesn’t work.
    rtsp://192.168.1.240:554/cam/realmonitor?channel=0-0&subtype=0 doesn’t work.
    rtsp://192.168.1.240:554/cam/realmonitor?channel={1, 2, etc}&subtype=0 works fine to show individual cam streams.

    Anyone know what the correct channel/syntax might be to bring up the matrix view that the NVR can send to the ViewPro app? (and then hopefully, to the Monocle/Alexa camera viewing system).



  • @flptrnkng

    I have not seen a device (NVR/DVR) that muxes multiple camera views into a single stream. I wish they did. Unfortunately Alexa only will render a single stream … so we can’t do any split screen functionality with multiple concurrent streams — at least not at this time.

    Thanks, Robert



  • @Monocle Thanks for the reply, but the NV4108-HS is sending a single stream that shows all the cameras in a matrix view. The Amcrest View Pro App can display the channel, something they call ‘Channel 0-0’ or ‘Channel 0-1’.

    I just need to discover the magic rtsp syntax to display that channel stream. The stream that is shown is a copy of the stream you get out of the HDMI port on the back of the NVR, so it’s definitely not the app compositing a bunch of channels.



  • @flptrnkng

    OH, OK … I was not aware of that Amcrest has that feature. Most of the time in their custom apps, they use a proprietary streaming method and maybe I just assumed they were sending individual streams and simply displaying them in regions of the screen.

    It might be worth reaching out to Amcrest tech support to see if this matrix-view is available via RTSP. Then you are right … it in theory would just be using the “right” RTSP URL.

    Please let me know what you find out.

    Thanks, Robert



  • @Monocle Ha! In a moment of inspiration, I tried Channel 9. Eureka! Matrix view.

    rtsp://IP:554/cam/realmonitor?channel=9&subtype=0

    This is trying with VLC. I’m about to make the changes in Monocle, and see if I can get it to work on the Alexa Show.

    Edit: Success! NVR camera Matrix View on Alexa via Monocle.



  • @flptrnkng

    That is FANTASTIC news! This is the first I have heard of someone actually getting a matrix view out of one of these NVRs on displayed on Alexa. I just ordered a NV4116E-HS from Amazon as it is on sale for Prime Day. Looking forward to trying this out myself.

    Thanks, Robert



  • I just tested this trick on a Lorex 8-channel DVR … and no luck. Hopefully the Amcrest 16 channel I have on order will work like yours!



  • @Monocle Not sure what channel # you’ll have to use with the 4116; I’m assuming 17, since 9 worked for the 8 channel 4108.

    Just tried this on my Toshiba FireTV, spoke into the remote control, “Show me the Cameras”, and the matrix view popped up.

    The matrix view you get is exactly the one you configure to show on the HDMI port of the NVR (there are several layout options).

    On the FireTV and the Echo Show 5, I needed the ‘@tunnel’ tag (and the Monocle Gateway running).

    A Fire 10 inch tablet worked without Gateway/tunnel.

    I believe the Amcrest NVRs are re-badged Dahua hardware; if you have one of those, it’ll probably work.



  • @flptrnkng

    I think the Lorex NVRs are also based on Dahua hardware. At least the newer Lorex models — they certainly feel like Dahua software and use the exact same URL formats and parameters. That is why I gave it a go. I tried various ports outside of the 1-8 range – but no luck.

  • On a side note, I was using a RTSP hardware encoder to re-encode the HDMI output from my existing Lorex NVR. So if this works on the new 16-channel Amcrest NVR, it will certainly eliminate the need for that step/effort. I probably won’t be able to test it until late next week, but I’ll post an updated with results/findings.

    @Monocle

    I think Blue Iris can present a muxed single stream composite of a group of cameras. I will try tonight and add to Monocle cameras .



  • @serodgers

    I would love to know if you get this working. I think other Blue Iris users have tried in the past without luck. I have not setup Blue Iris, but plan to try it out in the coming months.

    Thanks, Robert
