And a few more pictures from other news. It seems like a lot of different products are used.

For me the same at the Futian crossing coming back to HK from a day in the Shenzhen heat although in late 2014 they pulled you aside and pointed the camera at your forehead.
I guess I must have looked like a tomato but they waved me through after a temp check.
Did you pass through the road crossing or the metro crossing? The metro crossing didn't exist in 2003. In 2003 the road crossing had monitors installed at every immigration counter on both the China and HK sides, but they were not replaced when they got old. The few times infection scares (bird flu, swine flu, etc) have occurred since 2003 they have monitored the crowd, rather than the individuals at the counters. The crowd monitoring seems to have worked well at HK airport, so perhaps what is what they will do at all the ports moving forwards.

Thermal Cameras do appear to be an efficient and effective tool in the detection of people who have a fever amongst a crowd. Provided the cameras are correctly configured they will highlight people with a forehead temperature exceeding expected levels. Even false positives are better than letting someone spread the virus in your country like Typhoid Mary. The advantage of thermal cameras over using IR thermometers is large area detection and context. The operator can spot multiple fever ‘suspects’ and see where they are exhibiting a high temperature. To me, it seems an excellent application of the technology.

Metro after getting off the HK train system then onto the Shenzhen trains and the reverse in the afternoon.

Very interesting  :-+

It was nice that the report contained quite a lot of imagery from both the camera and also its production. That Microbolometer module design looks familiar.

I recognise the Black body they are using in the production area ...... it is American !

I have to wonder whether they are fabricating the microbolometer or have sourced them from outside Iran.

From a political point of view, this is a challenging situation...... suddenly thermal imaging technology is being seen as an essential tool in the detection of the corona virus, yet the technology is often controlled in its sale to some countries. On humanitarian grounds that could be considered unacceptable. However...... using thermal imaging cameras to detect a person who has a fever is not as reliable or simple as some might have you believe.... but that is something for another day and another thread.

@pauledd - Thanks for finding and sharing that link. Some things that interested me:

1 - the presumably 'home-grown' thermal screening software seen running has all its labels and controls in (US) English

2 - I can't quite read the grey text in the bottom right of the screen but it certainly starts
"Activate ........."
"Go to Settings to activate......."

949342-0

Does anyone recognise the software?

Separately, I wonder how much I could get if I hired out some of my radiometric thermal cameras to local businesses...?

I hope the Iranians do not need their black bodies serviced, the service centre is in Israel

so in the video they mentioned only 5 countries on the world have this technology? Which do they mean?
If Iran now openly has this technology and spreads it past their military, it will eventually fall in the hands of more terrorist groups in the region easier. Is it time for the US to drop some regulations to make US companies more competitive internationally?


@Ultrapurple they didn't pay for Windows and use it more than 30 days.

Seems to be a quite big core with shutter, maybe a Chinese "in-house" one delivered with an SDK? The software looks like those that you get sometimes with cheap webcams from Ali, you can see how bad the buttons design is with that text overlaying so they spend not a lot of effort into version 1.0.0.0  :D

The 5 countries are probably something like: US, France, China, Israel, Japan, Russia, Turkey...  Well the order of magnitude is right.

That iranian camera definitely use chinese hardware. Maybe Guide plug series?

Maybe they are indeed Iranian devices... That company "IOI" (ISFAHAN OPTICS INDUSTRIES) is a subsidiary of IEI (Iran Electronics Industries) and they are "manufacturer of Thermal Imagers" as globalsecurity.org says...

I see Amazon has now bought into the system:

https://www.reuters.com/article/us-health-coronavirus-amazon-com-cameras/exclusive-amazon-deploys-thermal-cameras-at-warehouses-to-scan-for-fevers-faster-idUSKBN2200HT

Quote
From the article:
The company performs a second, forehead thermometer check on anyone flagged by the cameras to determine an exact temperature, one of the workers said. An international standard requires the extra check, though one camera system maker said the infrared scan is more accurate than a thermometer.

I wonder which system maker that is.

My guess would be FLIR, as they've been more vocal in advertising thermal imaging for these purposes. Fluke on the other hand seem quite reserved. Both companies have very long supply chain lead times for (most) thermal cameras now, 3+ months here in Europe. Unless you're a governmental entity dealing directly with them, you're not getting one.

...
2 - I can't quite read the grey text in the bottom right of the screen but it certainly starts
"Activate ........."
"Go to Settings to activate......."
..

That's the Windows activation message in the background :).

Amazon can't get enough of the things:

https://www.reuters.com/article/us-health-coronavirus-amazon-com-cameras/exclusive-amazon-turns-to-chinese-firm-on-u-s-blacklist-to-meet-thermal-camera-needs-idUSKBN22B1AL

Quote
China’s Zhejiang Dahua Technology Co Ltd (002236.SZ) shipped 1,500 cameras to Amazon this month in a deal valued at close to $10 million, one of the people said. At least 500 systems from Dahua, the blacklisted firm, are for Amazon’s use in the United States, another person said.

...To see if someone has a fever, Dahua’s camera compares a person’s radiation to a separate infrared calibration device. It uses face detection technology to track subjects walking by and make sure it is looking for heat in the right place.

...In response to questions about the thermal systems, Amazon said in a statement, “None of this equipment has network connectivity, and no personal identifiable information will be visible, collected, or stored.”

I am not opposed to exercise, unless it is an exercise in futility.

So privacy concerns and facial recognition.

I think people are confusing the terms. They probably use some simple highlight marker or even a landmark detector trained on thermal images. Yet this is no facial detection and not recognition. It wont be able to identify different people. It might be able to make a list of different people and differentiate between them. But it's doing it on a ACG vector and not a normalized absolute vector. Depends on how the model is trained, but my test were not successful and the models on Google photos and windows photos did not work at all.

I doubt there is a custom model trained on thermal images.

I got tensorflow and tiny yolov2 running on K210 in less than a week. Nowadays machine learning is just commodity skill.

No. It's purely political. Dahua is known for making human tracking and behavior analyzing cameras for suppressing unrest in Uighur areas of China.
It's time for the Americans to learn they will pay with American lives for boycotting a foreign company doing its governmental business in a foreign country under the law of that country.

Its just convenient escape goat and the right timing for the presidential election, this will be intensified further until new president is elected.

Interesting quote ...
"...the fact that both parties think nothing of risking a confrontation with a major world power merely as a way to win power at home is… disturbing."

Are these cameras easily removable so people can 'borrow' them during the quiet or curfew evenings

for useful tasks like electronics and electrical troubleshooting etc

and returned back before daybreak for whatever purpose they are there for  :-//

I noticed Guide Infrared has a banner written "Open Source Open Minded" in their website (https://www.guideir.com/Public/Home/images/product/banner.jpg) , but I can't find any source code anywhere. Does someone have a source code at hand?

Their Chinese page says they are building an open platform and they look forward to collaborate.

So presumably they are only open to their partners?

Be aware that IR technology was a highly controlled technology, so there could be zero openness even to partners in the past.
