When you say "Made in the USA" what do you mean by that? Are you saying that all of the components are Made in the USA, or that some (or all) of the components are made in Asia but "assembled" in the USA?

Have there been any studies on adverse effects of being in close proximity with a blackbody?

Ethan, did you see where it was saving images? I just downloaded the latest version and in the settings dialog it doesn't have a checkbox for images which is confusing. It does confirm the same software version as yours .1.4.1.4, with a firmware of 3.8.1.24

Hello Brian,

Thank you for contacting Seek Thermal.

The ability to record and save image functionality has been removed from the current version of the software by the design team for evaluation. Changes are coming for that feature and when ready, will be announced on the main product page and rolled out with software updates.

You can keep up to date on all product info by going to the product page here:Seek Scan - Temperature Screening Thermal Camera - Seek Thermal | Affordable Infrared Thermal Imaging Cameras

Additionally, all data that is saved in the log file is saved by day.With the current version of the software, the Seek Scan system records these nine items:

Timestamp; SkinTemperature; BodyTemperature; ThresholdTemp; BodyTempOffset_Static; BodyTempOffset_Adaptive; BodyTempOffsetType; Disposition; Eyes_Found

And the information is captured in real time and stored in a log file (.CSV format) at this location on your local PC:C:\Data\SeekScan\<MONTH>\<DAY>\

Is there anything else we can do to assist you today?

Thanks,

Ray | Manager, Seek Support

Seek Thermal has updated the Seek Scan to version 1.6.1.6. Among UI and other updates, they have released an API which allows integration, but no video as of yet. Seek has mentioned that RTSP is coming soon, and we will update once it is available.

The setup with tri-pods feels a bit clunky. It would be nice if there was a wall mount included. Today I was setting one up with a customer and the thumb drive that typically holds the software install was blank; not a good look. I applied the 1.6.1.6 update and it seemed to improve the overall performance of the sensor. Apart from the minor hiccups, we have had good results with seek scan. It is very simple, easy to deploy, and has a great price point. As an integrator I don't feel comfortable recommending the other systems that are in the 10-12k range and produce erratic measurements.

We've found that microphone stands work great as they are stable and have a small footprint. You will need an adapter to bring it down the 1/4 20 and also an articulating joint so you can aim and adjust it.

Spencer, Good morning.

I'd like to chat with you regarding your experience with Seek Scan, specifically, the thumb drive issue you noted. This is the first reported issue of this kind and I'd like to close the loop with you.

We have heard complaints from end users regarding the thermal sensor revealing undergarments of some subjects tested. It would make sense for the software to include a privacy mask option to avoid this issue.

This would be an issues/concern for any thermal imaging system, especially during warmer summer months where clothing is generally thinner and will block/absorb less of a person's IR emission.

That is interesting feedback and probably has not been a significant issue given the limited use of thermal screening cameras during high temperature seasons.

I replied before including this Nature.com article looking at IR "shield" clothing, based on a composite fiber material: Development of a wearable infrared shield based on a polyurethane–antimony tin oxide composite fiber | NPG Asia Materials

The study notes:

Even when the person wears typical clothing, such as polyester or PU fabric, the IR and thermal radiation emitted from the human body passes through the fabric and becomes visible.

That IR shield clothing is quite interesting Sean. The feedback was specifically from a school setting. It is an awkward problem, and one that not many thermal manufacturers/integrators would have considered when it comes to thermal temp scanning.

I think you are right to assume this issue will be more prevalent in warmer climates, with less insulating clothes. Still, it is worth mentioning to prospective customers, and adjusting for in the setup of the sensor/blackbody.

Disagree. If you've spent much time working with thermal cameras, then you know they can potentially reveal a lot about what is under a persons clothes, particularly with lighter summer fabrics.

It seems to me that most security integrators working with thermal cameras prior to the pandemic would be using them in a perimeter protection application. I wouldn't think the of capturing of undergarments would be a much of an issue in these use cases.

I was thinking of that comment more along the lines of manufacturers being aware vs. integrators. Though I would still expect most integrators doing a lot of thermal camera projects would test the units in their office at least minimally, where you would tend to notice these things.

I had to do a thermal presentation if technology for a utility. All went well until a young woman entered the air conditioned scene within 5’ of a high resolution imager on a hot day. The manager insisted the “show is over” and we shut down.

Masking would help, reducing the resolution of the thermal imager, or only showing the visible image would solve this.
