Version1.7.0

New features​

Cluster operations​

  • Group updates for controllers and OSDP devices allow multiple controllers or devices to receive firmware updates simultaneously, reducing maintenance time.
  • Quick controller replacement simplifies replacing a failed controller without losing settings or reconfiguring access points.
  • Firmware version check when adding a controller to a cluster automatically checks compatibility with the current system version and warns about mismatches.

System configuration​

  • Custom controller names make controllers easier to identify and locate in the interface.
  • Alarm event configuration allows users to define which system events should be treated as alarms.
  • Automatic cluster authentication allows switching between cluster controllers without manually entering credentials, simplifying distributed system deployment.
  • Cluster time checks monitor time across all cluster controllers and warn about differences that may affect the accuracy of the event log.

Access control​

  • Preventing another passage until the first passage cycle is complete prevents repeated identification and a second person's passage before the first person has completed the cycle. This applies to turnstiles and vehicle barriers.
  • Soft AntiPassBack warns the operator about a repeated passage without blocking the passage itself.

Improvements​

Access control​

  • Separate schedules for each access point direction within an access profile allow different entry and exit schedules. For example, entry may be permitted from 08:00 to 20:00 while exit remains available around the clock.
  • Double-leaf door algorithms support different control scenarios for double-leaf doors.

Monitoring and diagnostics​

  • License plate recognition connection check verifies service availability when configuring the integration, helping detect connectivity problems.
  • All connected peripherals in Diagnostics and Service are displayed even when they have not yet been assigned to an access point.
  • Detailed event log filtering by Notification type makes important notifications easier to find.

Events and indication​

  • Resetting an access point alarm from the graphical plan allows the alarm to be cleared without restoring the passage sensor to its normal state.
  • Operator information in passage confirmation events from the Guard Post identifies the operator who confirmed the passage.
  • Employee information in access point mode changes made through a keypad reader identifies the employee who performed the action.
  • Card collection event records a card being collected by a turnstile card collector or a person leaving for the external zone with a single-use card.
  • Reader indication when passage is authorized from the graphical plan or the remote opening button activates the corresponding indicator when the door is opened remotely.

Backups​

  • Extended backup configuration filenames include the controller serial number and firmware version in addition to the date and time, making archives easier to identify and manage.

User interface​

  • Reworked Cluster Management section improves navigation and presentation of cluster controller information.
  • Optimized personnel and access point sections load employee, visitor and access point pages faster, particularly with large record sets.
  • Service renamed to Database Diagnostics more accurately describes the database maintenance functions of the section.

Developers (API)​

Bug fixes​

Critical fixes​

  • High-traffic turnstiles: fixed completed passages being recorded as incomplete during heavy traffic.
  • Visitors: fixed visitors being automatically deleted from the database 30 days after being added.
  • Event log: fixed high memory consumption and a frozen web interface when applying filters with automatic refresh enabled.

Integrations​

  • ZKTeco biometric terminals: fixed an incorrect number of people being written when updating terminal data.

Automation​

  • Employees with an unlimited-duration access profile can now trigger automation through a keypad reader.
  • Side A Unlocked mode: corrected automation behavior for access points equipped with a single relay.

Controllers and equipment​

  • NTP server: fixed the inability to select a controller with a five-digit serial number as the NTP server.
  • Access point operating mode schedules: fixed schedule settings being reset after a controller restart or firmware update.
  • Turnstile card collector: fixed a failed visitor passage incorrectly unassigning the card of the next person passing through the turnstile.

Event log​

  • Downloaded event log: fixed duplicate records in exported files.

Data import and export​

  • CSV visitor import: fixed import failures when the first passage and last passage fields were populated.
  • Exporting people with photos: fixed errors when exporting employees with attached photographs.
