2021 Geek Review: Top 3 BEST CHEAP Thermal Imaging Camera for Smartphones, FLIR ONE Pro and Seek Lose to InfiRay T3S.

Today I’d like to share a useful tool with you all – Thermal Imaging Camera for Smartphones. During circuit design or troubleshooting, Thermal Imaging Cameras can directly “SEE” the temperature distribution, and it’s easy to find and locate the insufficient heat accumulation and heat dissipation in circuit design. There are not many manufacturers of Smartphone Thermal Cameras on the market. I have used FLIR One Pro and Seek Compact Pro before, and last month I just got an InfiRay T3S. Let’s make a comparative evaluation.

From Left to Right – FLIR One Pro,InfiRay T3S,Seek Compact Pro

  1. Size, Weight and Material
    1. Size

FLIR One Pro is the largest because it is equipped with a visible light camera. InfiRay T3S has the largest resolution with bigger lens. Then Seek Compact Pro is the smallest product among those three and its lens is also small.

Size Comparison of Thermal Imaging Cameras

  1. Weight

All of the three products are light weighted.

  • FLIR One Pro – 38g
  • Seek Compact Pro – 15g
  • InfiRay T3S – 40g
  • Material

Material of the shell is able to affect the product’s strength, fall resistance, weight and electromagnetic radiation resistance.

  • Seek Compact Pro – it feels like cheap plastic, and it’s a kind of hard-shell plastic with average quality.
  • InfiRay T3S – its shell is made of metal only, and that’s why it is the heaviest among those three. The shell of InfiRay T3S is oxidized and it feels comfortable. The all-metal shell can not only protect the internal circuit board when it is impacted, but also could shield electromagnetic wave. Therefore, in some strong electromagnetic environment, such as substation, InfiRay T3S can work normally without being affected.
  • FLIR One Pro – it is made of synthetic resin. Feels soft and comfortable. It has a certain cushioning effect when falling. At the same time, FLIR One Pro does not have any lens exposed, which can protect the lens from being scratched or broken.
  1. Lens.

The working wavelength of thermal imaging is 7-14µm. During this wavelength, the best lens material is definitely Germanium. While some producers also use less expensive synthetic materials. Through research and direct consulting with manufacturers, we learned that the lens materials are as follows:

  • FLIR One Pro – Vulcanized Synthetic Materials
  • Seek Compact Pro – Vulcanized Synthetic Materials
  • InfiRay T3S – Germanium

Lens Size – FLIR One Pro, Seek Compact Pro, InfiRay T3S

For the infrared band, Germanium is a natural and excellent high transmittance material. Its transmittance is more than 95%. With the coating, the overall transmittance can reach more than 99%. While among synthetic materials, only selenium sulfide or zinc sulfide can pass through the infrared band. The transmittance of these materials is about 90%, and with coating, it can only reach about 95%. The higher the transmittance of the material, the clearer and cleaner the lens image can be. At the same time, because the infrared energy loss is small, the temperature measurement accuracy will be increased.

  1. Image Quality

The basic functions of Smartphone Thermal Cameras are imaging and temperature measurement.

Resolutions of the three models are:

  • FLIR One Pro – 160×120, with visible light camera 1440×1080 pixels
  • Seek Compact Pro – 320×240
  • InfiRay T3S      – 384×288

Let’s compare their image quality in below.

  1. Nearby Static Objects

­Start with FLIR One Pro, the overall image quality has been upgraded to a certain level with visible light images superimposed. For nearby static objects, the overlapping parts of infrared image and visible image can still match basically.

The resolution of Seek Compact Pro is 320 x 240 and its image quality looks almost the same as FLIR One Pro’s 160 x 120 resolution. Moreover, it can only see the hot target, and the reflected image of the floor is very fuzzy and almost invisible.

The images taken by InfiRay T3S have the highest resolution of 384 x 288. Sharp edges, clear details, sufficient sense of hierarchy, and even the images reflected from the ground are very clear.

  1. Nearby Portrait

Image processing ability of FLIR One Pro is good. Compared with Seek Compact Pro, FLIR One Pro has lower resolution, but better image quality. Due to the complexity of the shooting target and the clutter of the background, the point-to-point overlap of the visible light superposition part can not be achieved, and the superposition effect needs to be strengthened.

Take a look at those images taken by Seek Compact Pro, it feels like a “pit” with white on the outside and black on the inside everywhere. And the hair and background are almost mixed in Seek’s images.

While images from InfiRay T3S is much clearer. The hair and facial features of the model are very clear, and even the fat and muscle on her face can be seen clearly.

  1. Medium Range Image

Above images are all taken from twenty meters away.

The image quality of FLIR One Pro is good at close range, however when shooting a 1.7 meters high model from twenty meters away, it is difficult to distinguish the human body from the floor reflections. The superposition gap between visible and infrared images is becoming larger and larger from long distance.

With Seek Compact Pro, although the overall image still looks rough, and the “big pit” with white outside and black inside is still there, the details of the human body are better than those images taken by FLIR One Pro, which can distinguish the body and the reflection of the model.

InfiRay T3S’ image is very clean, showing model’s head, arms, even palms, feet and reflections of the human body.

  1. Long Range Image

FLIR One Pro’s infrared image is totally a blur without visible light camera overlap. While with visible light images, the effect of floors and windows is better. However with the increase of distance, the difference between visible and infrared images is becoming larger and larger. Thus in general, with the increase of visible light, the image recognition is much higher.

The “big pit” of Seek Compact Pro is finally out of sight in those images. Although the floors and windows can be distinguished, the trees and street lamps on the road in front of the building can not be seen.

Those images taken by InfiRay T3S can not only clearly distinguish the floor and windows, but also the logo of the open windows and the roof. Most of all, the street lights and signs in front of the building are clear as well. To be honest, if you only look at the front three pictures, you can’t tell what is in front of the building.

It can be seen from the previous images that InfiRay T3S has the highest resolution. Its image is delicate, clear and layered. Even without the visible light image superposition like FLIR One Pro, the image edge is very sharp. Especially when shooting nearby static target, the small lines and logo on the main target are very clear.

  • Temperature Measurement
  • FLIR One Pro: 20 – 400℃, accuracy ±3℃ or ±5%
  • Seek Compact Pro: 40 – 330℃, accuracy unknown.
  • InfiRay T3S      : 20 – 120℃, accuracy ±2℃ or ±2%

It can be seen from the above data that although the temperature measurement range of InfiRay T3S is not the widest, the temperature measurement accuracy is the most accurate.

  1. Temperature Measurement
  2. FLIR One Pro: 20 – 400℃, accuracy ±3℃ or ±5%
  3. Seek Compact Pro: 40 – 330℃, accuracy unknown.
  4. InfiRay T3S      : 20 – 120℃, accuracy ±2℃ or ±2%

It can be seen from the above data that although the temperature measurement range of InfiRay T3S is not the widest, the temperature measurement accuracy is the most accurate.

  1. Body Temperature Measurement
  • FLIR One Pro – 35.5℃
  • Seek Compact Pro – 33℃
  • InfiRay T3S – 36.13℃

Generally speaking, the temperature measured by FLIR One Pro and InfiRay T3S is close to the normal forehead temperature range (35 ~ 37 ℃), while the temperature measured by Seek Compact Pro is quiet off. Even though the temperature measurement accuracy of the Smartphone Thermal Cameras is lower than the thermometer, its advantage is that the temperature measurement speed is faster. You are able to get the temperature instantly by checking the forhead.

  1. PCBA Temperature Measurement

FLIR One Pro, with the help of visible overlap, can see positions of components, however the problem is that the thermal and visible images do not match very well.

It’s kind of hard to find positions of each component with Seek Compact Pro. Just could barely see PCBA itself.

InfiRay T3S is able to provide a clear image and it’s easy to locate the component with the highest temperature.

  • Parameter Settings

For temperature measurement, the setting of parameters has the greatest influence on its accuracy. All three products have emissivity settings. Both FLIR One Pro and Seek Compact Pro come up with several settings which is simple and easy to understand, like Sub Light, Semi Matte, Semi Highlight and Highlight. However expert users may not be able to set emissivity for specific material to get accurate result. InfiRay T3S has temperature measurement parameters such as emissivity, ambient temperature, humidity, distance, reflection temperature, temperature correction and etc. Although it is troublesome for primary users to understand and set these parameters, if they are set well, hardware engineers can get the most accurate temperature. The reflection temperature is a very important parameter and it can accurately measure the temperature of the peripheral device beside the high temperature device.

  • Battery Lifetime
  1. Battery Lifetime

FLIR One Pro equipped with battery that needs to be charged before use. Seek Compact Pro and InfiRay T3S are powered by smartphones through USB connection.

The battery lifetime of FLIR One Pro is very short. It only lasted about thirty minutes when I used it. When ambient temperature is lower, the battery lifetime is even shorter.

  • Conclusion

Considering materials, image quality, temperature measurement accuracy, InfiRay T3S is the best and highly recommended. (All rights reserved. Please indicate the source if repost)

But before you get involved with crypto, you must understand some of the facts about these currencies and the crypto technology that underpins it all. 

As a starting point, here are eight fascinating facts about cryptocurrency.  

1. Cryptocurrency Started 14 Years Ago

In 2008 as a reaction to the banking crash of that year, a mystery person named Satoshi Nakamoto launched the first cryptocurrency. The first currency is still the most famous one: Bitcoin. 

2. There Are Over 10,000 Cryptocurrencies on the Market

Most people, when pressed, can probably and a handful of cryptocurrencies. But did you know that over 10,000 types of cryptocurrency are on the market?

The biggest lesson from this is to do your research when investing if you aren’t familiar with the name of the cryptocurrency. 

3. There Are Now Cryptocurrency ATMs

Did you know that there are thousands of special ATMs for cryptocurrencies?

However, unlike a normal ATM where you withdraw cash, these ATMs allow you to buy Bitcoins directly using your bank debit card. Or you can use a protocol such as The Graph. Here’s more information on how to buy Graph

4. A Cryptocurrency Might Be a Unicorn

No, we aren’t referring to those magical horse-like creatures with horns.

A unicorn is a financial term for private startups valued at over $1 billion. Some cryptocurrencies have reached this magic number, so you might hear them referred to as unicorns. 

5. Vietnam Uses Crypto More Than Any Other Country

It might surprise you that the US and China don’t rank highest in cryptocurrency transactions.

That award goes to Vietnam. The Vietnamese have one of the most positive attitudes to crypto. Predominantly, the younger generation invests heavily in new crypto markets. 

6. There Are Only 21,000,000 Bitcoins

The investor of Bitcoin wanted to create a currency that would have a finite number of coins floating around the market.

So there are only 21,000,000 Bitcoins in existence, and each one requires computer power to mine. Although only 10% is left to mine, that could take until 2140! 

7. Scammers May Steal Your Computer Processing Power

Why Should Employees Receive CT Sexual Harassment Training?

Why Should Employees Receive CT Sexual Harassment Training?

Providing sexual harassment education is crucial in order to maintain a safe workplace environment. Despite this, many firms have seen an increase in the number of claims of workplace harassment, and not all of them have implemented the essential training programs for their employees.

 It is absolutely critical to provide sexual harassment training in the workplace because it has the ability to make workplaces safer for everyone. People will benefit from the training since it will assist them in understanding what sexual harassment is and how to spot it if it is taking place in the workplace. The small effort required by businesses to provide the training is well worth the return on their investment, which is measured in terms of enhanced productivity. Click on the link for more https://en.wikipedia.org/wiki/Sexual_harassment.

Harassment Training

When the Supreme Court handed down a series of landmark decisions, the court made a distinction between sexual harassment committed by employees who are ordinarily authorized to act on behalf of the corporation (such as managers and some supervisors) and sexual harassment conducted by coworkers.

Employees who are subjected to sexual harassment by their coworkers are frequently found liable only if the harassment began or continued as a result of the company’s carelessness on the part of the harasser.

After learning of an instance of sexual harassment, a company must take immediate action to protect the harassed employee or else it would be considered negligent. A sexual harassment complaint would almost always necessitate an investigation by the company, as well as action to prevent the harassment from continuing or repeated in order to avoid legal liability.

Managers and supervisors benefit from sexual harassment training because it helps them understand their duties and responsibilities in the event that they learn or suspect that there has been sexual harassment. Read more here.

Putting up a fight against suspected negligence

It is possible that sexual harassment training will safeguard you from being accused of being careless in three ways. As a first step, employers can take a pro-active approach to protecting their employees against sexual harassment by informing all employees about the forms of behavior that are not acceptable in the workplace.

When it comes to the workplace, sexual harassment is a big problem. Through the training process, the employer’s commitment to sexual harassment prevention and the implementation of a policy against sexual harassment will be made evident. This will aid the employer in fighting against an allegation that it tolerated sexual harassment and failed to take reasonable steps to avoid it.

Furthermore, by emphasizing during CT sexual harassment training that the company has a complaint reporting mechanism and therefore by encouraging harassed employees to use that process, the employer can take advantage of Supreme Court decisions that provide a defense to allegations of sexual harassment against the company in the future.

A firm may still be judged negligent even if an employee completes the reporting procedure and the company fails to investigate and respond in a timely and reasonable way and in good faith to the employee’s complaint. Training employees to be aware of the complaint system is a vital first step in preventing sexual harassment. This will help to reduce the likelihood of coworkers being held accountable for sexual harassment they see.

Finally, training managers and supervisors in the handling of sexual harassment charges instills in them the need of addressing sexual harassment allegations with decency and courtesy. In the case of sexual harassment performed by managers and certain supervisors, businesses might be held accountable even if they were not aware of the harassment. Managers and supervisors should be aware of their rights and obligations in this circumstance.

Increasing the productivity of your workers

Having employees who have experienced workplace sexual harassment are less productive, which puts firms at risk of legal liability as a result. A 2007 study undertaken by researchers at the University of Colorado found that employees who have been sexually harassed are less committed to their jobs than their peers. Those who feel valued are more efficient, but employees who have been sexually harassed are less productive, according to research.

Absenteeism has increased as a result of sexual harassment, which is largely to blame for this increase. Workers who have been sexually harassed are more likely to take sick leave in order to recover from the trauma of being assaulted, according to research. The inability to control sexual harassment results in an increase in an employer’s sick leave charges, which includes the cost of replacing harassed employees with temporary workers.

A high frequency of sexual harassment is associated with a high turnover rate among employees in organizations, according to the Human Resources Management Institute. The loss of a knowledgeable person leads in a rise in training expenditures as well as a decline in the overall efficiency of the organization as a whole.
