EZVIZ takes security and user experience issues very seriously. Accordingly, we provide outstanding maintenance of our products that includes technical support and regular releases, which include security updates, bug fixes and new functions based on users' feedback and industry best practices.
Generally, version updates are provided regularly and mainly for product performance. If there are some actual conditions, like some critical vulnerabilities are reported, an immediate update will be arranged. However, EZVIZ may does not provide upgrade for older firmware versions that are too old and have few users, even for security issues.
To ensure your product is fully protected and properly working, we'd always recommend you keeping your product updated. We will work with you to make upgrading as easy as possible and have product updates occur at a convenient time for you. EZVIZ will also send you regular reminders to update your product.
For security reasons, no downgrade methods will be provided once firmware is updated. EZVIZ will make every effort to maintain compatibility between firmware versions.
