Public space, tenant space, and parking share the same property, and they don’t keep the same hours. Coverage has to work during the day and after the building is empty.
Doors get added over time, visitors still need a way in, and not every location has an IT team. Access has to keep staff, tenants, and guests in the right places without slowing down the workday.
If you run a few locations and nobody wants a recorder sitting in a back office, Alta removes that server from the picture. Cameras record to their own onboard storage and upload to the cloud, and updates happen on their own.
If your IT team wants the video on your own servers, or policy says it cannot leave the site, Unity keeps it on your network. You can still check in from off site through Unity Cloud Services.
