Plavidian Sentry™ Camera Verification Add-On for Direct Mail
Plavidian Sentry™ is piece-level camera verification inside your Plavidian account, offered as an add-on you choose per job for letter-size mail. With it, every piece is read as it is addressed, matched against your list, and reconciled before the job leaves the floor.
As each piece runs, Cognex machine-vision cameras read it and verify it against the job's expected list. A piece that does not read cleanly, or does not match what should be there, is automatically diverted for controlled recovery and reprint.
Read, check, divert, recover
Reads every piece
Cameras read the address and barcode data on each piece as it runs, at production speed.
Checks against the list
Each read is matched to the expected print file bound to that job, not to a generic count.
Diverts failures
Misfeeds, double-feeds, jams, out-of-sequence, and poorly printed pieces are pulled off the line automatically.
Controlled recovery
Diverted pieces are reprinted and re-run so the list is completed.

What it catches
The failures that otherwise go unnoticed
Unreadable or missing data
A piece that will not read cleanly is caught during production instead of going missing without anyone noticing.
Mechanical failures
Misfeeds, double-feeds, and jams remove pieces from a run while the counter still reports them as addressed.
Wrong or duplicated pieces
Out-of-sequence and duplicate pieces are identified against the expected file instead of shipping unnoticed.
Documented
Audit reports in your Plavidian account
Completed jobs that carry camera verification have Print and Camera Audit reports in your Plavidian account, so you can review and keep a piece-by-piece record of what ran.
