Start with the device and the symptom.
A short, reproducible report helps us identify the right next step. Contact the team for device operation, installation references or integration questions.
Identify your equipment
Include FCV4914 and its configuration, order reference if available, firmware and application version. A photo of the device label helps distinguish configurations.
Show the setup
Describe the power supply, interface, connected controller or host, and mounting. Include a wiring diagram or clear connection photo where relevant.
Describe what happens
List the steps, expected result, actual result and whether the issue is repeatable. A short video or sanitised log can help. Remove passwords, tokens and personal biometric information.
Find the right reference.
Use the download centre to find documents by model. If your configuration’s manual is not listed, request it with the model and firmware so the team can identify the appropriate version.
Before returning equipment.
Contact the team with the product and order details before sending a device back. Warranty eligibility, inspection, repair, shipping and return authorisation are reviewed against the applicable order and product terms.

Common questions for FCV4914.
What should I include in a technical support request?
Include the overseas product model, firmware or software version, connection method and a short sequence that reproduces the issue. Screenshots, indicator behavior and relevant logs help; do not send passwords, access credentials or personal biometric data.
What should we check if a device repeatedly restarts?
Compare the power supply voltage, current capacity and wiring with the specification for the selected configuration. If the problem continues, record whether it happens at startup or during a particular action and send the model, firmware and observations to technical support.
What lighting conditions should we consider?
Strong backlight, direct sunlight, reflections and close-range lighting can reduce capture quality. Evaluate the terminal in its intended position and avoid pointing the camera directly toward a bright window or concentrated light source.
What kind of enrollment photograph should we use?
Use a clear, front-facing JPG without beauty filters, heavy makeup, sunglasses, a mask or other facial obstruction. File size and image dimensions can vary by software and model, so confirm the current import requirements before preparing a large enrollment set.
What should we confirm before connecting a face terminal to the network?
Confirm whether the selected configuration uses wired networking, Wi-Fi or another connection method, then collect the network and platform settings required by that system. A local network connection does not by itself prove that the device is connected to the management service, so verify both states separately.
