Who this guide is for: Administrators responsible for installing and managing Anviz clock devices connected to Sense HR.
Platform: Sense HR & Anviz Clocks
Already using the legacy ClockTransactionsTransmitter with Anviz clocks?
See our upgrade guide
Overview
Anviz clocks are attendance and authentication clocks used to record employee clock-in and clock-out events.
Depending on the model of Anviz clock, employees can authenticate using:
NFC / RFID cards (all models)
fingerprints (Anviz C2 pro only)
facial recognition (Anviz FacePass and DeepFace models only)
In this article, you will learn how to:
Install and configure the Sense Clock Transactions Service
Connect your Anviz clock devices to your network
Sync employees from Sense HR to your clocks
Register authentication methods (card, fingerprint, or face)
Verify that clock-in data is successfully received in Sense HR
Clock events are transmitted to Sense HR through the Sense Clock Transactions Service — a local Windows service.
How the Clock Connects to Sense HR
Anviz clock devices do not connect directly to Sense HR.
A local service handles communication between the clocks and the platform.

First time installation and integration
Step 1: Save bootarg file:
Save to desktop (this can be deleted after install)
Step 2: Create clock IP list
Open Notepad and enter the IP addresses of your clock(s).
💡 You can find the clock IP address on the device under Network settings
For multiple clocks, the IP(s) should be separated with a comma (no spaces).
Example:
192.168.1.10,192.168.1.11
Save the notepad file as:
clockip.txt
💡 Recommended: Use a Static IP Address
For reliable operation, it is recommended to assign a static IP address to each clock.
To configure this on the clock:
Open the device menu
Go to Network settings
Change from DHCP to Static
Enter the following:
• IP Address (e.g. 192.168.1.50)
• Subnet Mask (e.g. 255.255.255.0)
• Default Gateway (e.g. 192.168.1.1)
All fields must be completed correctly. Missing or incorrect values may prevent the clock from connecting to the network.
These values must match your organisation’s network. If unsure, contact your IT team.
Step 3: Install the Sense Clock Transaction service
Download the latest version Sense Clock Transactions Service (V4.0.0).
Extract ZIP file
Right-click the installer and select:
Run as AdministratorFollow the installation steps
Step 4: Configure the Service

(this setting is OFF by default)
Once enabled, updates made on one clock will automatically sync to all connected clocks every 5–10 minutes, including:
• Name
• Card
• Fingerprint templates
• Face templates
Note: Biometric data is not stored by Sense.When syncing across devices, only a secure biometric template (a mathematical representation of the fingerprint or face) is used — not the original image or scan.
Click Save
✅The settings are now saved and Clock Transaction Settings can be closed
Step 5: Add Integration Files
Go to:
C:\ProgramData\ClockTransactionsServiceCopy the following files to the folder
•.bootarg
(the most recent bootarg file provided by Sense and saved to your desktop)
•clockip.txt
(the file that you created containing the IP(s) for you Anviz clock(s)
Step 6: Start the Service
Right click the Sense Clock Transactions Service and select:
Run as administratorSelect:
Start

🖊️ Note: You do not need to keep the Clock Transaction Service open for it to transmit your clock data. The service will run in the background as long as the Windows device is powered ON.
Step 9: Confirm Employees Have Synced
Open the Employees tab
Confirm employee records are listed
You will see:
Device ID
Sevice IP
Employee ID
Employee Name
Card / fingerprint / face status (for first time set up this will not be filled yet)
This means:
Employees have been sent from Sense HR
Users exist on the clock devices
Step 10: Verify Employees on the Clock devices
At this stage, users already exist on the clock(s).
On an Anviz clock device:
Open the menu
Log in as admin
Go to User / Users
Search or scroll to find employees
Your employee list should be visible on the device
Step 11: Enroll a user for clock-in on a clock device
Before rolling out to all employees, it is recommended to test the setup by enrolling a single user.
Use your own employee record where possible, as this allows you to quickly complete the test using your card or biometric details.
On the Anviz clock device:
Select the user for registration
Open their profile
From the user's information screen, register one of the following:
• RFID / NFC card:
Swipe the RFID Card on the device RFID Card read area (it will display the RFID Card number in the Card number text box)
• Fingerprint (C2 Pro only)• Face recognition (FacePass / FaceDeep only)
For full step-by-step guidance, see:
Once enrolled, users can clock-in on any connected clock.
Step 12: Test the system
For the enrolled user:
Perform a clock-in
Wait a few minutes
Confirm event appears in Sense HR
Automatic syncing for new employees
When a new employee is added in Sense HR, they are automatically sent to all connected Anviz clocks.
The employee is created as a user on each clock, and a Time & Attendance ID is assigned and stored in their employee record.
No manual setup is required.
To check the new employee sync has completed in Sense HR:
Navigation path:
HR Dashboard > People
Steps:
Go to People list
Find and open the employee profile
💡 You can use search, sort, or filters to find the profile quicklyOpen the Employment details screen (sidebar menu)
Check that the Time & Attendance ID field has been populated
This ID matches the employee’s ID on the clock and in the Sense Clock Transactions service.
Sync an Employee to Clocks
If an employee does not appear on a clock, you can trigger a sync.
Navigation path:
HR Dashboard > People
Steps:
Go to People list
Find and open the employee profile
💡 You can use search, sort, or filters to find the profile quicklyClick the More actions (...) menu (upper right)
Select Anviz sync
This sends the employee record to all connected clocks.
Monitor the system
The health tab in the Sense Clock Transactions Service (running Clock Status Hub 4.0) allows you to monitor the health of the system.
To use:
Open Sense Clock Transactions Service from your Windows device
Click the Health tab and check:

Time Settings and Daylight Saving Settings
Clock time is managed as part of normal system operation.
If daylight saving changes are not applied automatically on your device, they can be adjusted from the clock’s time or DST settings.
💡 Menu names and navigation may vary by device model.
To update daylight saving settings:
Open the device menu
Log in as an administrator
Go to Time, Date/Time, or DST settings
Update the daylight saving offset and start/end rules for your location
For example, using an Anviz C2 Pro in the UK:
offset: +1 hour
start: March / Sunday / Last / 01:00
end: October / Sunday / Last / 02:00
If you are unsure which values to use, check your local daylight saving rules before saving.

Click to see the answers to frequently asked questions
Q: How long does it take for clock-in data to appear in Sense HR?
A: Clock events are sent to Sense HR automatically and usually appear within a few minutes.
If data does not appear after a few minutes, check that the Clock Transaction Service is running and the clock is connected.
Q: Do I need to keep the Clock Transaction Service open?
A: No. you do not need to keep the Clock Transaction service open, as it runs in the background.
You can close the application, but the computer running the service must remain powered on and connected to the network.
Q: What happens if the service PC is turned off?
A: If the service PC is turned off, clock events will not be sent to Sense HR.
The clock will continue to store events locally and send them once the service is running again.
Q: How do I know if a clock is connected?
A: To check if a clock is connected, open the Clock Transaction Service and go to the Devices tab.
A connected clock will show a status of Connected.
Q: What should I do if a clock does not appear in the Devices tab of the Sense Clock Transactions Service?
A: If a clock does not appear in the devices tab of the Sense Clock Transactions Service, check the following:
• the clock IP address is correct in clockip.txt
• the clock is powered on
• the clock and service PC are on the same network
Q: Do I need to set a static IP address for each Anviz clock?
A: It is recommended to use a static IP address for each Anviz clock.
If a clock uses a dynamic IP address, it may change over time and the connection to the service may be lost.
Q: What happens if the Anviz clock IP address changes?
A: If the IP address of an Anviz clock changes, the clock will no longer connect to the service.
You will need to update the clockip.txt file with the new IP address and restart the Clock transaction service.
Q: Do I need to add every employee on to the Anviz clock?
No, you do not need to manually add employees to the Anviz clock.
Employees are automatically added to the clock when they are created in Sense HR.
However, each employee must still be registered with a card, fingerprint, or face on the device (options vary by Anviz device model)
Q: Can employees use any Anviz C2 pro clock in the organisation?
Yes. Once enrolled, employees can clock in and out on any connected clock.
Q: What should I do if a new employee does not appear on the clock?
A: If an employee does not appear on the clock, use Anviz sync from the employee record in Sense HR (People > [select profile] > More actions (...) menu > Anviz sync).
Then check the clock again after a few minutes.
Q: What happens with the Anviz clock record when an employee leaves?
A: When an employee leaves the organisation, they are automatically removed from all Anviz clocks after their leaving date.
They will no longer be able to clock in.
Q: Can I update clock in methods for an employee on the Anviz clock?
Yes. If clock in method updates are made on an Anviz clock (such as card or biometric enrolment), they can be synced across other clocks if sync is enabled in the Sense Clock Transaction settings.
Q: What should I do if an employee cannot clock in?
A: If an employee cannot clock in, check:
the user exists on the clock
the user is registered for clock in (card, fingerprint, or face)
the correct clock in method is being used
Q: Why is a clock-in time different from when the data appears in Sense HR or the Sense Clock Transactions Service app?
A: Clock events may take a few minutes to sync.
The timestamp in Sense HR always reflects the actual time the employee clocked in, not the time that data appears in the Sense Clock Transaction Service or Sense HR.
Q: Can I use Wi-Fi instead of Ethernet?
A: Yes, you can use Wi-Fi or Ethernet but a stable connection is required.
Unstable Wi-Fi may cause delays or connection issues.
Q: What should I do after Anviz setup is complete?
A: When the Anviz clock(s) and Sense Clock Transaction Service setup is complete and before rolling out to employees:
test clock-in with a user
confirm data appears in Sense HR
check all clocks are connected
