Secure, reliable and scalable
keyless access control for
critical infrastructure

Efficient Security without Anonymity

Identification at access protects assets more than robust physical security

  • Security is at the core of everything we do
  • Locks and access points are not directly connected to the cloud
  • Automatically and definitively identify who, when and where
  • Only unlocks on short-range proximity requests
  • Eliminate wait times and address overburdened NOCs
  • No need for internet connectivity and works in power outages
  • Even Failsafe Unlock identifies the user in the logs

“These three principles are at the core of everything we offer at Sera4”
