Smart TVs are powerful. They connect to Wi-Fi, run apps, store login credentials and sometimes even include cameras and microphones. That convenience also makes them part of your home network, which means they deserve the same security attention as your laptop or smartphone.
If you own a smart TV, here is what you should know.
Why Smart TVs Can Be a Security Risk
Most smart TVs:
-
Store streaming account passwords
-
Connect to your home Wi-Fi
-
Use built-in microphones for voice commands
-
Sometimes include cameras for video features
-
Automatically download app updates
If the TV is outdated, misconfigured or connected to an unsecured network, it can become an entry point into the rest of your devices.
This does not mean smart TVs are unsafe. It means they need basic security hygiene.
1. Keep the TV’s Software Updated
Manufacturers regularly release firmware updates that fix bugs and patch security vulnerabilities.
Go into your TV’s settings and:
-
Turn on automatic updates if available
-
Manually check for updates every few months
If your TV no longer receives updates, it may be time to consider replacing it. Unsupported devices are a common weak point in home networks.
2. Secure Your Home Wi-Fi First
Your smart TV is only as secure as the network it connects to.
Make sure your router:
-
Uses WPA3 or at least WPA2 encryption
-
Has a strong, unique Wi-Fi password
-
Has default admin credentials changed
-
Has firmware updates enabled
For added protection, consider placing smart home devices, including your TV, on a separate guest or IoT network if your router supports it. That limits access to your main devices.
3. Disable Features You Do Not Use
If your TV includes:
-
A built-in camera
-
Always-on voice assistants
-
Automatic content recognition features
Disable them if you do not need them. Fewer active services mean fewer potential vulnerabilities.
You can also physically cover cameras if your model includes one.
4. Be Careful With Apps
Only download apps from the TV’s official app store. Avoid sideloading apps or using unofficial streaming software.
Also:
-
Delete apps you do not use
-
Log out of services you no longer need
-
Avoid reusing the same password across multiple streaming platforms
Using a password manager can help you generate unique logins for each service.
5. Adjust Privacy Settings
Many smart TVs collect viewing data to improve recommendations or serve targeted ads.
Check your privacy settings and:
-
Disable data sharing where possible
-
Turn off personalized advertising
-
Review user agreements periodically
You may not be able to disable all tracking, but you can usually limit it.
6. Power Down When Not in Use
Some smart TVs remain partially active even when “off.” If you want maximum security and privacy:
-
Turn off quick-start features
-
Power down fully when not in use
-
Unplug if you will be away for an extended period
It is a simple step that reduces exposure.
7. Watch for Signs of Trouble
Unusual behavior can indicate an issue. Pay attention if your TV:
-
Opens apps on its own
-
Shows unexpected pop-ups
-
Runs noticeably slower
-
Changes settings without your input
If that happens, reset the TV to factory settings and reconnect it to a secured network. If problems persist, contact a professional.
Smart TVs Are Computers, Treat Them That Way
The biggest mistake homeowners make is thinking of smart TVs as appliances instead of connected devices. In reality, they are internet-enabled computers with access to your network.
The good news is that securing them does not require advanced technical knowledge. Keep software updated, secure your Wi-Fi, limit unnecessary features and stay aware of privacy settings.
A few simple steps go a long way toward protecting your home network.
