Bulk manage visits
Open Hamilton Visitor, click Administration, then "Visits management" in the Tools section.
Target the visits: search by visitor, company, resident, badge or purpose, set the date and site, and click Search — "The visits list" shows the matches.
Select the visits and apply the maintenance action (correction, closure, deletion) — "The modification was successful" confirms.
Bulk manage visitors
In the Tools section, click "Visitors management".
Same principle on visitor records: target with the filters, select, and apply the action.
Bulk manage visitor companies
In the Tools section, click "Visitor companies management".
Target and maintain companies in bulk; combine with "Company change for a visitor group" to re-attach visitors when merging companies.
Work safely
Filter narrowly before selecting: date range, site, exact company.
Export the list first (left-menu Export tool) — your undo insurance.
Run one action on a small batch, verify, then scale up.
Good to know
These bulk screens need the Tools administration right — see "Manage users and rights groups".
For identity duplicates, the deduplication tool is the right instrument — see "Import data and clean up duplicates".
