@Leofr1cs The initial delay seems to be entirely based on the RTSP player and likely H.264 decoding built into the Alexa hardware devices. Some camera, mostly based on the Dahua hardware like Amcrest seem to only have around a 5 second delay while others often have closer to 10 second delays. In my testing using a high resolution versus a low resolution seemed to have little impact on improving this latency. I have also tested these types of RTSP streams using Raspberry Pi hardware and that too has similar stream startup latency – so I’m just guessing that a combination of the hardware and software codecs just perform better on full desktop/laptops versus the limited capacity of the low power ARM-based devices. So could it be further improved? Yes, I’m sure there is room for improvement in the optimization on these devices for RTSP streams and the supported video and audio codecs. Will Amazon improve it? Well, thats impossible to know – but there really has not been any significant improvement (that we have witnessed) in streaming performance and compatibility since the first release of the Echo Show Gen 1. PS. Does the Monocle Gateway add latency to the streaming. Well, possibly … but minimal. From what we have seen in testing it does not add any more than 1 second to the streaming latency. Of course it could be worse in sub-optimal network conditions. Thanks, Robert

@pattyland You may be right on the authentication. However, it should work with either setting. If you choose “DIGEST” we attempt DIGEST authentication first if possible and revert to BASIC if DIGEST is not available or fails. If you choose “BASIC”, we attempt BASIC authentication first unless we receive information in the request/response headers that indicate that the endpoint requires DIGEST. So this authentication setting really should work with either value, perhaps just more optimized if its set correctly. Ås for the audio codec, maybe that depends on the actual camera stream that Synology is attached to. I’m not 100% sure, I’d have to set it up again and test. I know my cameras attached to my Synology NAS are producing AAC audio streams, but I’m not sure if Synology transcodes the audio to G711. This audio codec setting provides guidance to the Alexa devices as to which type of audio stream to expect; however, in practice I’m not sure that it matters too much as it seams Alexa will accept either one at runtime and not reject the stream outright if this setting is incorrect. It is a good idea to set it correctly if you know its wrong, because perhaps there is more at play than we realize in side the black-box that is Alexa. Thanks, Robert

@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
