This function replaces [system.security.isScreenLocked](versioned_docs/version-8.1/appendix/scripting-functions/system-security/system-security-isScreenLocked.md). Any scripts containing Vision Client scoped functions that were replaced with system.vision syntax will still work to maintain backwards compatibility.
