HomeBoard—A Security Camera Viewer App for Android TV & Google TV—Try It Now for Free!

by
Install and Use HomeBoard on Android TV

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.

Two-Way Audio Security Cameras—Here’s How They Work

by
Two-Way Audio Cameras Work

Two-way audio cameras do more than just record sound. They also allow you to communicate with people through the camera.

Security cameras with two-way audio have become increasingly popular, especially among smart camera users. I’ve also noticed growing demand for this feature. In fact, some potential customers specifically ask me whether the camera they’re about to purchase supports two-way communication.

In the past, adding two-way audio to a security camera system often required a manual setup using additional accessories, such as an external microphone and speaker. However, things are much simpler today. Many modern security cameras already have both a microphone and speaker built in, so you can listen and talk directly through the camera using your smartphone.
