Is my smart TV watching me?

For most TVs, the honest answer is less about hidden cameras or secret microphones and more about a feature most owners have never heard of: Automatic Content Recognition, or ACR. Microphones did become part of the story in 2026, and that is covered further down.

What ACR actually does. ACR works by periodically taking small samples of what is displayed on your screen, whether that is a streaming show, a cable broadcast, a game console, or a connected Blu-ray player, and matching those samples against a reference database to identify exactly what you are watching. It does this regardless of the source, which is what makes it different from a streaming app just knowing you watched something inside that app. Some ACR systems also log which HDMI input is active and when.

What it is used for. The primary purpose is advertising: building a viewing profile used to sell targeted ads on the TV’s home screen and, in many cases, shared with third-party data brokers and measurement companies. It also feeds “smart” content recommendations. Manufacturers frame it as improving your experience; it is also a meaningful revenue stream, since many TV makers sell hardware at thin margins and make up the difference through advertising and data partnerships built on exactly this kind of viewing data.

Why so many TVs have it switched on. ACR is not a rogue feature from one bad manufacturer. Samsung, LG, Roku, Amazon Fire TV, Vizio and most other major platforms include it, usually tied to a “viewing information” or “interest-based advertising” agreement during setup. Some brands now describe it as opt-in, and in 2026 Samsung and LG settled lawsuits brought by the Texas attorney general that require clear consent there. In practice, though, setup screens often offer a single “Agree to all” button, and firmware updates can add new agreements later. So “off unless you agreed” often means “on, because you agreed without noticing.”

The good news: it is usually easy to turn off. Unlike some tracking, ACR is typically controlled by a single, clearly reachable setting, even if the exact menu label varies by brand:

• Samsung: Viewing Information Services, in the TV’s privacy settings.
• LG: Live Plus, under General → System → Additional Settings, plus the Viewing Information agreement under Support → Privacy & Terms.
• Roku: Smart TV Experience or Use Info from TV Inputs, in Privacy settings.
• Amazon Fire TV: Interest-based ads and Device Usage Data, in Privacy Settings.

What about the microphone? Many recent TVs support hands-free voice (“Hi LG”, “Hey Google”, Alexa) with a microphone built into the TV, not just the remote. In September 2026, a Gamers Nexus investigation reported that an LG TV captured audio while it appeared to be off and scanned the home network for other devices. LG disputes the audio claims and says standby listening only happens if you turned on hands-free voice. It confirmed the network scanning. See Is my LG TV listening to me? for the details. Whatever your brand, turning off hands-free or far-field voice in the TV’s settings, and using the microphone switch if your TV has one, closes this path.

The option that works on every brand. If you want the TV to share nothing, do not connect it to the internet at all. Use a separate streaming box or stick over HDMI instead. A guest Wi-Fi network is a middle ground that keeps the TV away from your other devices.

Turning ACR off does not disable your apps or streaming services; it only stops the screen-sampling and reporting. For the exact menu paths, screenshots, and additional settings worth checking on your specific TV, see the guides for Samsung, LG, Roku, and Fire TV.
