To find out whether a smart-home device receives security updates, identify its exact model and hardware revision, check its firmware version and update history through the manufacturer’s documented channels, then look separately for a model-specific support end date. An update menu—or evidence that the device was updated in the past—does not establish that security support is still ongoing.
Check the device’s update status
-
Identify the exact model and hardware revision
Record the model number and hardware revision from the device label, companion app, or original packaging. Find the matching product page on the manufacturer’s official support site, checking that it applies to your region and revision. Similar product names can have different firmware and instructions.

Find the installed firmware version
Open the product’s app or settings interface and note the displayed firmware or software version. If shown, record when the device last checked for or installed an update. Menu labels and locations vary, so follow the device manual or the manufacturer’s support instructions rather than assuming every app uses the same path.

Check for an available update and use the documented method
Look in the manufacturer’s app or device interface for an update check, or follow the official instructions for that model. NIST’s technical catalog describes both remote and local update mechanisms and identifies authorization and verification of a valid source as important update capabilities, with digital signatures, checksums, and certificate validation among its examples. Install updates through the manufacturer’s documented channel.
-
Review dated firmware releases and security notices
On the exact model’s support page, look for firmware history, release notes, security bulletins, and manufacturer notices. Check dates and whether notices apply to your device revision. A version number by itself cannot tell you whether the manufacturer is still maintaining the product; the release history and support statement provide different evidence.

Find the support commitment
Search the official product documentation for terms such as “security update support,” “end of support,” “end of life,” or a stated support period. Confirm that any date or policy applies to your exact model. NIST’s manufacturer-information catalog treats communication about unsupported devices and the security impact of ending support or functionality as relevant information for customers.

Ask the manufacturer if the answer is unclear
Contact support in writing with the model, hardware revision, and region. Ask whether security patches are still planned and whether there is a stated end date. Keep the answer and its date; release histories and support policies can change.

- PRIORITIZE WHAT MATTERS: Set activity zones to monitor specific areas for motion or people. Free person and motion detection helps reduce unwanted alerts and notifies you when activity is detected.
- VERSATILE VIDEO STORAGE: Store footage locally via a microSD card (up to 512GB)* or via cloud with a Tapo Care cloud subscription. Tailor your security to suit your needs, whether indoor or outdoor, you have the storage option you need.
- FULL-COLOR 1080P, DAY AND NIGHT: See clearly in low light with a large-aperture lens and built-in spotlights. Capture full-color night vision up to 30 ft away to monitor for possible intruders or motion.
Interpret what you find
- An update is available: Follow the manufacturer’s instructions for the matching model and revision. An update mechanism should not be treated as proof that an update came from an authorized, valid source; NIST identifies those as important security properties of update processes.
- There are recent releases or security notices: This is evidence of recent activity, but check the notice’s date, affected models, and any stated support period before drawing a conclusion about future support.
- You find no recent release history: That alone does not establish that support has ended. Look for an explicit lifecycle notice or ask the manufacturer for a model-specific answer.
- The manufacturer says support has ended: Read its notice for security implications and for what functionality remains. The notice can help you assess whether continued use is appropriate; do not assume that every feature will stop working when updates end.
What to compare before buying a device
There is no universal minimum security-support duration established for all consumer smart-home devices in the cited NIST material. Compare the commitments and practices the manufacturer actually publishes for the products you are considering:
- Whether a support duration or end date is stated for the specific model.
- How recent and dated its firmware and security-release history is.
- Whether updates are automatic or require a manual check, and how update notices are delivered.
- What the manufacturer says will happen to security and device functionality when support ends.
NIST guidance discusses update criticality and timing, potential impacts or dependencies, and end-of-support communication as useful customer information. Its guidance is not a consumer certification and does not guarantee that a particular retail device implements every capability it describes; update considerations can vary with form factor, use case, organization, and controls.

Why ongoing updates matter
NIST SP 800-213A, published in 2021, states: “Software update is central to vulnerability management by allowing for software to be changed when vulnerabilities are found and remediated.” That explains why checking for an update and checking the support commitment are separate tasks: the first concerns the device’s current software, while the second concerns whether the manufacturer says it will continue addressing vulnerabilities.
