HomeBoard might be one of the apps you can use to view live security camera feeds on an Android TV or Google TV.
Before recommending it, I wanted to try it out for myself.
The app is called HomeBoard, and it’s distributed as an APK file. Many people are understandably cautious about installing APK files from outside official app stores. In this case, I believe HomeBoard is worth trying, but you should still take precautions. To be on the safe side, I recommend using a secondary account rather than your primary account when setting it up. Here’s a look at my experience testing HomeBoard on my Android TV.
