Dashboard Metrics
The top section displays key access card metrics that provide instant visibility into your facility's access control system health and card inventory status.
Total Access Cards
Description: Complete count of all access cards registered in the system
Icon: Blue card symbol
Includes: Active, expired, suspended, and deactivated cards
- Represents total card inventory across all users and zones
- Includes both physical RFID cards and virtual access credentials
- Essential for card procurement and inventory management
- Updates when cards are issued, activated, or deactivated
Active Cards
Description: Number of cards currently authorized for access
Icon: Green checkmark symbol
Status: Valid, non-expired cards with active permissions
- Only cards with current authorization and future expiry dates
- Excludes suspended, revoked, or administratively disabled cards
- Represents actual operational access capacity
- Should align closely with current employee/user count
Expired Cards
Description: Cards that have passed their expiration date
Icon: Yellow/orange clock symbol
Access: Automatically denied at all access points
- Includes cards that expired naturally based on set duration
- Does not include manually suspended or revoked cards
- High count may indicate need for card renewal process
- Users with expired cards will be unable to access facility
Hourly Access Patterns
The Hourly Entrances bar chart displays access card usage distribution across 24-hour periods, revealing facility access patterns, peak times, and unusual activity windows.
Chart Features
- X-Axis: 24 hours from 0:00 to 23:00 in hourly increments
- Y-Axis: Number of access card uses (automatically scaled)
- Bars: Blue vertical bars indicating access volume per hour
- Hover Tooltips: Shows device name and exact access count (e.g., "Entrance @ 8:00 - 24")
- Grid Lines: Horizontal reference lines for easier reading
Understanding Access Patterns
Typical access patterns by facility type:
| Facility Type | Expected Peak Hours | Pattern |
|---|---|---|
| Office Building | 7:00-9:00, 17:00-19:00 | Morning arrival, evening departure spikes |
| 24/7 Facility | 7:00, 15:00, 23:00 | Three shift changes throughout day |
| Data Center | 9:00-17:00 | Business hours only, minimal after-hours |
| Residential | Distributed 6:00-22:00 | Even distribution, individual schedules |
| Healthcare | 6:00-8:00, 14:00-16:00 | Morning staff, afternoon shifts |
Security Anomalies
Watch for unusual patterns that may indicate security issues:
- Late Night Spikes: Unusual access at 23:00-5:00 requires investigation
- Weekend Activity: Access during closed days may be unauthorized
- Volume Drops: Sudden decrease could indicate system failure
- Unexpected Peaks: Abnormal spikes outside normal hours need review
Access Card Types Distribution
The donut chart visualizes the breakdown of access attempts by authorization status, providing immediate insight into system security effectiveness and potential issues.
Chart Categories
- Authorized (Green): Successful access attempts with valid, active cards
- Denied (Red): Rejected attempts due to expired, invalid, or unauthorized cards
- Unknown (Gray): Unrecognized cards or system read errors
The center number shows the total count of authorized attempts, representing successful facility access events.
Healthy Distribution Indicators
What to expect in a well-managed system:
- ✅ 95%+ Authorized: Most attempts should be successful
- ✅ < 5% Denied: Small percentage from occasional expired cards
- ✅ ~0% Unknown: Should be minimal or zero in normal operation
Warning Signs
Unusual distributions that require immediate attention:
- 🔴 High Denied Rate (> 10%): Many expired cards or unauthorized access attempts
- 🔴 Many Unknown Cards (> 5%): Unregistered cards, damaged readers, or security breach
- 🔴 Sudden Spike in Denials: Mass card expiration or system misconfiguration
- 🔴 Zero Activity: System may be offline or not recording properly
Recent Denied Access Attempts
The Denied Access Attempts table is your primary security monitoring tool, displaying all rejected access attempts with full details for investigation and response.
Table Columns
- User: Name or identifier of person/card attempting access
- Description: Reason for denial (expired card, invalid card, no permissions, etc.)
- Date: Timestamp of denied attempt (YYYY-MM-DD HH:mm:ss format)
- Count: Number of consecutive denied attempts (indicates persistence)
Common Denial Reasons
| Description | Cause | Action Required |
|---|---|---|
| Card Expired | Expiration date passed | Renew card with new expiry date |
| Invalid Card | Card not registered in system | Investigate source, register if legitimate |
| No Access Permission | Card lacks zone authorization | Assign appropriate zone access |
| Card Suspended | Administratively disabled | Verify reason, reinstate if appropriate |
| Outside Schedule | Access attempted outside allowed hours | Adjust schedule or deny if correct |
Investigation Priority
Focus your security investigations on:
- Count > 5: Indicates determined unauthorized access attempts
- Unknown Users: Unregistered cards are security red flags
- After Hours: Denials at 23:00-5:00 require immediate review
- Same User Repeatedly: May indicate forgotten card renewal or malicious activity
- Unknown Cards: Priority investigation - potential security threat
- Document Actions: Log all investigations and resolutions
Time Period Filtering
The time period selector allows you to analyze access control patterns across different timeframes, revealing trends and identifying anomalies specific to each duration.
Available Time Periods
| Period | Label | Security Use Case |
|---|---|---|
| 24 Hours | 24h | Real-time security monitoring, daily access review |
| 7 Days | 7d | Weekly patterns, identify unusual weekly activity |
| 1 Month | 1m | Monthly security reports, card expiration trends |
| 6 Months | 6m | Semi-annual audit, seasonal access changes |
| 4 Years | 4y | Historical analysis, long-term security trends |
Analysis Use Cases
- 24h View: Morning security check, investigate overnight activity
