Alexa devices
ViewBridge is intended for Alexa devices with a screen that can display a camera stream. The supported device family is Amazon Echo Show.
The Alexa camera interface can exist on other Alexa-enabled displays, but ViewBridge has not established support for Fire TV, third-party televisions with Alexa built in, Echo Spot, or other display products. Treat those devices as unconfirmed until they have been tested with your exact model and Alexa account.
Screenless Echo devices can understand Alexa commands, but they cannot display the live camera picture.
The camera endpoint uses Alexa’s CAMERA category and the camera streaming interfaces. Amazon’s current interface documentation is the source of truth for device and interface changes:
Cameras
ViewBridge is designed for generic network/IP cameras, not a particular camera brand. Your camera must provide:
- A local RTSP stream that the gateway can reach on the home network.
- H.264 video.
- A stable stream path and camera credentials.
- A video-only stream for the simplest setup. Audio is not required.
The current Alexa camera profile uses RTSP, H.264, 1920x1080, and no audio. If your camera has several stream profiles, choose an H.264 profile at that resolution first. A camera may offer other resolutions, but the configured gateway profile and the Alexa stream profile must agree.
There is no vendor certification list. A camera that exposes RTSP can work if its URL format, authentication, H.264 encoder, keyframe behavior, and network reachability are compatible. ONVIF discovery is not required; enter the RTSP address on the local gateway page.
Home network
The camera, gateway, and Echo Show should normally be on the same home network. The gateway hostname must resolve to the gateway’s private LAN address from the Echo’s network.
| Requirement | Expected setup |
|---|---|
| Camera to gateway | Local RTSP connection over the home network. |
| Echo Show to gateway | Local connection to the gateway hostname and TCP port 443. |
| Gateway address | A stable private IPv4 address such as 192.168.1.42. |
| Router | No port-forward for the gateway or camera RTSP port. |
| DNS | The gateway hostname resolves to its private LAN address. |
Some routers reject public hostnames that resolve to private addresses as a DNS-rebinding protection. If that happens, use the router’s documented local DNS override or hostname allowlist. Do not solve it by opening the gateway to the Internet.
Alexa regions
Alexa connects a skill locale to an Alexa service region. The current ViewBridge infrastructure is prepared for these three regions:
| Alexa service area | AWS region used by the skill | Typical locale example |
|---|---|---|
| North America | us-east-1 (N. Virginia) | en-US |
| Europe and India | eu-west-1 (Ireland) | de-DE for Germany and Austria |
| Far East and Australia | us-west-2 (Oregon) | ja-JP or en-AU |
The Alexa account marketplace, skill distribution, language, and Lambda region must agree. For a German-language Alexa account in Germany or Austria, the relevant region is Ireland (eu-west-1). A skill that is not distributed to your marketplace will not appear during setup.
Amazon changes locale and device availability over time. Check Alexa interfaces and supported languages and Alexa’s regional guidance if your country or language is not listed here.
