The selection of security cameras that work with Alexa is already impressively large, especially considering the integration has only been available for a little over a month. With these cameras, you can ask Alexa to view their live feed on the Amazon Echo Show and soon on Fire TV devices, but if the selection seems pricey, you can build your own using a Raspberry Pi.
Sam Machin has built his own camera that’s compatible with Alexa’s live feed viewing feature. He’s the one who created the first web interface for Alexa, as well as a $10 Echo and other interesting Alexa hacks. Using a Raspberry Pi, a camera module, and some code that he has published on GitHub, Machin has rolled his own camera that can be called up at will on the Echo Show. He has provided instructions on GitHub for how to make your own Alexa compatible camera.
