FireTV 4K Stick (3rd Generation) 
The Monocle skill can be used to display local IP camera feeds to your FireTV 4K Stick (Generation 1) however, only when running the Monocle Gateway service locally on your network.
The Monocle Gateway service is required because the latest Amazon Alexa enabled device implement further restrictions and only permit RTSP connections from these devices to camera endpoints over encrypted (TLS) transport layer and only permitted to connect on port 443 using fully qualified domain names with valid a SSL certificate. These rigid requirements make it near impossible for most IP cameras to work directly with Alexa devices and thus the Monocle Gateway service acts as a bridge by fulfilling these requirements and enabling communications with your local IP cameras.
