Are Home Cameras and Smart Door Locks Safe? How to Check Smart Home Security
Checking Smart Devices by Verifying Account, Shared Users, Updates, and Remote Access
Home cameras, smart door locks, speakers, and lighting offer the convenience of checking and controlling your home from outside. On the flip side, if accounts or sharing permissions are poorly managed, information like videos, daily routines, and entry details may be unnecessarily exposed. Instead of simply turning off devices, it's more effective to first check who is accessing them and with which accounts.
The checklist includes multi-factor authentication for the manufacturer's account, a list of shared users, connected devices, firmware and app updates, and remote access capabilities. If there has been a move, job change, or changes in family structure, check if previously invited users still remain. Additionally, verify the recording storage location and retention period for home cameras, as well as the use of microphones.
Avoid using the initial password as is; change it to something that does not overlap with other sites. If possible, connect smart home devices to a guest network or an Internet of Things (IoT) network that is separate from the main PC used most frequently.
This list is about how owners can organize their access permissions, not about bypassing the lock of a specific device or viewing any video footage. Do not reset communal equipment or rented housing without the permission of the managing entity. Reassess whether to continue using devices that no longer receive updates due to the end of manufacturer support in sensitive areas.

In smart home security, the first thing to check is not the devices themselves, but the accounts and sharing relationships. Even if you change your password, if family sharing, installer accounts, or old mobile phone sessions remain, access can continue. Distinguish between admin, family, and guest permissions, delete any users that are no longer needed, and then enable login notifications.
Position home cameras away from bedrooms or areas where documents or screens can be viewed, and consider using a lens cover or physical power cutoff when not in use. Check whether recordings are stored in the cloud or on local storage, and review the retention policy after deletion. Use features like voice recording and facial recognition only when necessary.
Updates should be checked not only for apps but also for the entire system connected, including hubs, cameras, door locks, and routers. If automatic updates are supported, confirm the settings; for devices that have received an end-of-support announcement, consider replacement or network isolation. When passing on device ownership, remove them from your account and follow the manufacturer’s reset process.
Finally, let's organize the list of devices and management accounts so that the family can respond together. When notifications of unfamiliar logins or movements appear, deciding who will check and what screens to preserve can reduce confusion.
