Automatic camera startup. On page load, SignalLens requests camera access only; microphone access is disabled and no audio track is requested or captured. Opening this emailed link records the user’s prior explicit consent for periodic server-assisted JPEG frame analysis when that capability is available. When a valid sid is supplied, the latest complete JSON snapshot is stored for 24 hours and is retrievable by anyone possessing that SID. If the server-authoritative administrator policy enables anomaly-frame retention, only frames matching selected fresh integrity signals, event severity, or artifact thresholds are included as bounded compressed base64 JPEG evidence; frames with no enabled policy match remain image-free. Integrity freshness is relative to browser-reported capture timestamps and is checked for internal consistency, not independently timestamped by the service. Disabling the policy stops new evidence capture and clears retained frames in active tabs, but a prior SID snapshot can remain until an image-free replacement is confirmed or its 24-hour retention expires. Your browser and operating system camera indicators remain visible.

Administrator risk policy

Defaults active

Configure the server-authoritative aggregate workspace-risk score and SID anomaly-frame evidence policy for this SignalLens service. Access is protected by the current administrator session; validated settings are stored by the service, cached locally only for display and notification, and trigger authoritative refetches in other open SignalLens tabs on this origin.

Privacy impact: When enabled for a page with a valid SID, matching 192×144 JPEG frames are encoded into the SID result and become retrievable by anyone possessing that SID for the result's 24-hour lifetime. Frames with no enabled policy match remain image-free. Disabling stops new evidence capture and clears active-tab evidence immediately, but a prior SID snapshot can remain available until an image-free replacement is confirmed or its 24-hour retention expires. Hard limits are 20 images, 32 KiB decoded per image, and 400 KiB aggregate base64 data.

Risk is a configurable screening indicator, not proof of identity, deception, manipulation, or unauthorized activity.

Prior explicit consent from the emailed-link workflow is recorded when this page loads. SignalLens sends the first current camera frame when server capability is ready, then sends another only after the previous server job is deleted and a minimum five-second gap has elapsed. Jobs never overlap.

Server capability is loading. Prior explicit consent from the emailed-link workflow is recorded for temporary periodic frame analysis on this page load.

Periodic uploads start automatically when camera and server capability are ready. Stop monitoring releases the camera track and requests deletion of the current server job.
