Foscam R2 with Lenovo Smart Tab [SOLVED]
-
Thanks so much for trying to help… Unfortunately no love, I will try replacing my firewall with a different device to see if it is indeed some setting with the firewall. If that doesn’t work, do you have any suggestions on who and how to contact amazon support? I.e. is there an email address to contact?
-
If the Lenovo Smart Tab won’t work with the DEMO camera feed then I don’t think its an issue with your firewall. The DEMO camera feed is available publicly and thus as long as the Alexa device can access the Internet, then nothing firewall related should have an impact in this case.
Basically here is what should happen:
1.) You ask Alexa for a camera feed.
2.) Your Lenovo Smart Tab will contact Alexa servers to initiate the camera stream by name.
3.) The Alexa servers contact the Monocle servers with a request for the camera stream. (InitializeCameraStream)
4.) Monocle servers receive the Alexa InitializeCameraStream request and respond with the appropriate details (RTSP URL, username, password, etc) for the Alexa device to make a RTSP connection to the IP camera.You can verify this by inspecting the “
Camera Feed History” on your camera in the Monocle Web Portal.
You should see something like this in your feed history for the demo camera stream when using tag@noproxy:{ "timestamp": "2020-01-21T17:19:06.750Z", "request": "InitializeCameraStreams", "response": [ { "uri": "rtsp://demo.mproxy.io:443/test", "resolution": { "width": "1920", "height": "1080" }, "authorizationType": "NONE", "videoCodec": "H264", "audioCodec": "NONE", "protocol": "RTSP" } ] }5.) This response is then returned to the Lenovo Smart Tab by the Alexa servers and then the tablet should immediately attempt to establish a (secure) connection to the camera stream, negotiate a RTSP session and start playing the stream.
So as long as this is showing up in your camera feed history, then that tells us that the Alexa servers are accepting your request and we are responding with the demo camera stream information and at that point its entirely up to the Lenovo Smart Tab to make the connection to the camera stream and start playing the stream.

Unfortunately I don’t have access to any direct means of Amazon support … just the general customer support URLs.

@Monocle Thanks for providing that context and detail.
When i tested again today, i do see the Demo Direct feed now!!!
[ { "timestamp": "2020-01-21T22:38:39.607Z", "request": "InitializeCameraStreams", "response": [ { "uri": "rtsp://demo.mproxy.io:443/test", "resolution": { "width": "1920", "height": "1080" }, "authorizationType": "NONE", "videoCodec": "H264", "audioCodec": "NONE", "protocol": "RTSP" } ] },So this indicates that indeed the Alexa on Lenovo Smart Tab actually works. How do we test it through the proxy?
-
I tested the Demo Direct Feed with and without the “@noproxy” tags.
- It does indeed work with the “@noproxy”
- It does NOT work with blank tags section
-
Here is my Demo Direct Feed, Can you validate that i have this configured correctly. Note the port change and tag, everything else should be the same
This one going through the proxy with @proxy-tcp tag shows this:

Can you revert back to the URL
rtsp://demo.mproxy.io:443/testand test again both with and without the@noproxytag. I’m just trying to isolate the issue and make sure we are working on the exact breakdown.If it’s absolutely working with tag
@noproxyand definitely not working with no tags, then that points to a new issue we have never seen before. But it’s a clue and possibly we can move to the next diagnostics step once this is confirmed.Thanks, Robert
-
After confirming the steps above in my last post, you can move forward and try RTSP URL:
rtsp://demo.mproxy.io:554/testand include both of the following tags:@noproxy, @tunneland lets see if anything new shows up in the gateway log.If the key to getting this working is the tag
@noproxy, then I suspect I know what the issue is. Tag@noproxytells our servers NOT to use a RTSP REDIRECT. In fact, I should change it to@noredirectto avoid confusion because the word “proxy” in this case means something different than the @proxy used with the gateway. This issue has never come up before and we have never shared this tag for use until now. By default we use a RTSP redirection stage as this was the original working implementation method before Amazon started implementing stricter and stricter access policies.Thanks, Robert

Yes, i have 2 demo cameras in my configuration
The Direct one that isn’t using the gateway is the first camera that i have gotten to work at all. I am 100% positive that it is working using the @noproxy and as soon as i remove that it stops working
-
I will configure Demo Proxy with @noproxy, @tunnel and see what happens
-
So i tried Demo Proxy (should rename that to Demo Gateway)
I tried with a combination of
- @noproxy, @tunnel
- @noproxy, @proxy
- @noproxy, @proxy-tcp
Interestingly enough i didn’t get anything in the monocle gateway logs
I read a note somewhere that said the demo stream only works with proxy-tcp and not proxy or tunnel tags
for all 3 Alexa attempts to load the stream and then says “Sorry, Something Went Wrong”
-
OK, take a look in your Camera Feed History and lets make sure that the Alexa InitializeCameraStreams response is pointing directly to your gateway DNS hostname and not our redirection server. Just post the response here and I’'l review it.
Thanks, Robert
-
Again thank you so much for working with me on this. I am willing to do whatever it takes to make this work…
I tried those tags with my legit cameras (Foscam and Amcrest) with (@noproxy, @tunnel )
I get “Sorry, Something Went Wrong”
-
No problem, let just stick with
@noproxy, @tunneltags on “Demo Proxy” for the time being. Even if it does not result in the demo camera working, it keeps things simpler for now – the first goal is just to see TCP connections from the tablet in the Monocle Gateway log after an Initialize Camera stream.Thanks, Robert

Here is Demo Proxy

Okay, i hear you about the @tunnel, @noproxy… i will leave it like that from now on

Here it is with
Here is the WebUI log
[ { "timestamp": "2020-01-22T00:52:50.078Z", "request": "InitializeCameraStreams", "response": [ { "uri": "rtsp://demo.mproxy.io:554/test", "resolution": { "width": "1920", "height": "1080" }, "authorizationType": "NONE", "videoCodec": "H264", "audioCodec": "NONE", "protocol": "RTSP" } ] },This time she said “Im not sure what went wrong”
-
Note that it did not show the initial Loading Demo Proxy screen that i am used to seeing
-
OK, so looking more in-depth, I was wrong, the tag
@noproxyshould not be included. It looks like when using the@tunnelor@proxy(or@proxy-tcp) tags we skip that redirection step anyways.So just include
@tunnelonly and then what I would expect is additional lines in the gateway log like this example:------------------------------------------------- INITIALIZE RTSP STREAM: Demo ------------------------------------------------- - NAME : Demo - MAKE : Monocle - MODEL : Demo - LABEL : PRIMARY - URL : rtsp://demo.mproxy.io:554/test - UUID : STREAM:86f988fe-1293-43c6-90c6-43d880e78103 - SESS : 92dfd8ac-8b4b-4430-8545-3de0fb1e551c - MODIF : Tue Jan 21 2020 20:08:57 GMT-0500 (Eastern Standard Time) - TAGS : @tunnel ------------------------------------------------- 2020-01-22T01:09:04.887Z [INFO] [10.1.2.90:51902 <ryt2x7rZI>] RTSP CLIENT SOCKET CONNECTED 2020-01-22T01:09:05.015Z [INFO] [10.1.2.90:51902 <ryt2x7rZI>] RTSP CLIENT ATTACHED TO STREAM: Demo (STREAM:86f988fe-1293-43c6-90c6-43d880e78103) 2020-01-22T01:09:05.088Z [INFO] [10.1.2.90:51902 <ryt2x7rZI>] RTSP ENDPOINT SOCKET CONNECTED {demo.mproxy.io:554} 2020-01-22T01:09:05.089Z [DEBUG] [10.1.2.90:51902 <ryt2x7rZI>] [CLIENT REQUEST] --> [DESCRIBE] rtsp://fb78694e-95a9-4e5f-8708-787c6bc33067.mproxy.io:443/STREAM:86f988fe-1293-43c6-90c6-43d880e78103?session=92dfd8ac-8b4b-4430-8545-3de0fb1e551c 2020-01-22T01:09:05.089Z [TRACE] [10.1.2.90:51902 <ryt2x7rZI>] [CLIENT REQUEST] --> [HEADERS] { "accept": "application/sdp", "user-agent": "Fire OS/6.0 stagefright/1.2 (Linux;Android 7.1.2)", "cseq": "1" } 2020-01-22T01:09:05.091Z [DEBUG] [10.1.2.90:51902 <ryt2x7rZI>] [ENDPOINT REQUEST] --> [DESCRIBE] rtsp://demo.mproxy.io:554/test 2020-01-22T01:09:05.091Z [TRACE] [10.1.2.90:51902 <ryt2x7rZI>] [ENDPOINT REQUEST] --> [HEADERS] { "accept": "application/sdp", "user-agent": "Fire OS/6.0 stagefright/1.2 (Linux;Android 7.1.2)", "cseq": "1" } 2020-01-22T01:09:05.183Z [DEBUG] [10.1.2.90:51902 <ryt2x7rZI>] [ENDPOINT RESPONSE] <-- [200 (OK)] <cseq=1> (session=undefined) 2020-01-22T01:09:05.183Z [TRACE] [10.1.2.90:51902 <ryt2x7rZI>] [ENDPOINT RESPONSE] <-- [HEADERS] { "cseq": "1", "date": "Wed, 22 Jan 2020 01:09:05 GMT", "content-base": "rtsp://demo.mproxy.io:554/test/", "content-type": "application/sdp", "content-length": "294" }In this example, you can see the RTSP CLIENT SOCKET CONNECTED message from my Alexa device inside my network.

So it’s certainly acting like the tablet is not able to establish the RTSP connection to the gateway.
I know we have already checked the DNS, SSL cert, IP address, access to port 443, etc. So I think we know that a connection is not getting blocked by the typical actors.
Amazon does not provide us any details on how to further diagnose Alexa camera connection related issues on the Alexa hardware side. It’s just a black box to us.
I think some network packet sniffing might be in order to try and determine if the Alexa device is trying to connect to the gateway. This seems to be where we are stuck once again. Tracing outbound requests from the tablet device should reveal TCP attempts on port 443 to the gateway.
