5.5 FAQ
1. Q: Why some people only have captured images but without any measured temperature?
A: Because the face appears outside the IR imaging and inside visible light imaging, so the
system cannot measure temperature. Configure a ROI in the area of IR imaging for visible light
camera.
2. Q: Why the temperature measurement result delays for 5 seconds or more?
A: Maybe because the image pushing tactic of algorithm configuration is best quality pushing,
so the system will push the final result after a track ends. Change it into timed image pushing and
test again.
3. Q: Why there is no whitelist alarm after I created a whitelist?
A: After user created a whitelist, user has to go to camera management, press ‘edit’ button, and
select the whitelist in ‘Deployed face library’, then the whitelist alarm function will take effect.
4. Q: Why face images on clothes or in cellphone can be captured and have measured
temperature?
A: Ming Ji system doesn’t support live detection function.
5. Q: Why the visible light picture disappears but IR picture are normal?
A: First check the power and network of visible light camera, then check the network
configuration in Ming Ji software. If the system is used locally, please confirm the DNS
configuration is null.
Q: Why the IR camera keep emitting sound regularly?
A: The sound is made when internal components of IR camera calibrate every few seconds.
Q: Why the visible light camera only shows time but without any image?
