Infiray DP09 Thermal Imaging Monoculars

Infiray DP09 Thermal Imaging Monoculars

Check Price on OpticsPlanet

The last monocular on my list is also one of the smallest, but it still manages to pack a lot into such a compact frame. 

The Infiray DP09 Thermal Imaging Monoculars weigh just 85g and, at just shy of 8cm long/4cm wide, it’s the perfect size for pockets. This makes it easy to take with you wherever you go and won’t weigh your jacket down with unnecessary bulkiness.  

Its compact size is arguably its best feature, but it also comes with a magnification range of 1-2x, ideal for spotting close targets in even better detail. The lens’ thermal sensitivity starts at 60mK, which is good for something at this price point.

With a refresh rate of 25Hz, the Infiray DP09 lacks the fluid clarity of some of the other monoculars I’ve highlighted, but if you’re a patient hunter, this shouldn’t prove too much of a disadvantage. 

The focal length is on the low end at 9mm, but this also means that the FOV is wider than some monoculars. In short, if you’re looking for a thermal monocular suited to something like backyard use, the Infiray DP09 should fit the bill. 


  • Compact
  • Mid-range resolution (256×192 pixels)
  • Rechargeable CR123 battery


  • Low magnification range
  • Not as durable as other monoculars

Points To Consider When Buying A Thermal Monocular

The best thermal monocular devices do not come cheap, so it is vital to carefully weigh up all your options before parting with your money. In no particular order, here are the other factors to consider while shopping for a thermal monocular. 

Detection range

Generally, better quality monoculars have a longer detection range. Some of the best thermal monocular devices can detect heat signatures up to, but not limited to, 4,000 yards. 

Identifying and distinguishing what you’re seeing is an underlying factor to keep in mind here. Before reaching for your rifle, it’s essential to know whether your monocular has detected a person, elk, or deer. 

If you intend to use your monocular in the confines of the backyard, there is no need to spend extra on a long-range detection device. 

Display resolution

Pixels make up the display, and the more pixels you have, the better the image quality. Cheaper thermal monoculars will have a 160×120 resolution, while at the high-end, you’ll get resolutions of 640×480. 

There is a 500% difference in the number of pixels between a 160×120(19,200 pixels) resolution and a 384×288(110,592 pixels) display. Since more pixels mean better images, you are better off buying a 384×288 than a 160×120 if display resolution is the deal-breaker.  

The certainty at which you can spot and identify creatures strongly depends on the image’s quality on your display. 

Refresh rate

The speed at which a thermal monocular refreshes to present a more natural image is essential, especially if the target is moving or you’re on a moving vehicle or platform. A 30Hz refresh rate might seem the same as 60Hz when stationary, but it is too slow when there is movement. 

Thermal monoculars with a 60Hz refresh rate cost a little more because you can scan a field and spot at a much faster rate. Typically, a refresher rate of 50Hz works well with most thermal monocular devices.   

Battery life

As you have seen in this article, several batteries are not user-friendly for replacing or swapping. A battery that cannot last an hour might not be worth it as you will get very little done, whatever the activity. 

The battery also affects the monocular’s temperature, so be aware of this as well. A battery with a five-hour lifespan but is easily replaceable is not a bad deal. Anything over 12 hours of continuous operating time in a thermal monocular is not typical and will affect the price.   

Operating temperature

Some thermal monoculars will fizzle out if the temperature is too high or too low. The thermal monocular’s response to temperatures depends on the technology or software and the battery. 

Checking on the temperature range before buying will save you the disappointment of losing your target over frozen waters because the monocular failed to work. The operating temperature might be less of a factor if you’re buying a thermal monocular for personal and home security, with little chance of the device ever leaving the house.



Short-range thermal monoculars have a base magnification that makes creatures appear 1.4x to 1.5x closer. Some don’t have any magnification at all. Mid-range and long-range monocular devices typically have a zoom that starts at 2.5x. 

The best thermal monocular devices have in-built software to reduce image distortion when using digital zoom. Magnification, or zoom, takes more importance when hunting than when used as a body cam, for example. 

If you’re a serious hunter, then the zoom capabilities of a monocular should be high on your checklist, as it might be the difference between a trophy and a tag.  

Color palettes

The settings associated with color palettes help distinguish between targets and the background. Some thermal monoculars have two modes, black hot and white hot. Warmer objects are black in black hot mode, and warmer objects are white in white hot mode. 

That is sometimes enough because you can clearly distinguish between a person and an animal, depending on the display type and resolution. It is also closely linked to how we view the world as humans. A decent thermal monocular will have adjustable palette parameters or settings. 

Identification range

If you’re a hunter that fully understands the different animal movements, then identification range might not be as significant a factor as it is for the rest of us. The identification range is typically less than the detection range on thermal monoculars. 

High-quality thermal monoculars can positively identify a creature and put a clear image on the display for you to see and make your next informed move. A coyote and dog look the same on an average monocular, while a high-quality monocular will save you from explaining why you shot the neighbor’s pet. 


Thermal monoculars are not cheap by any stretch of the imagination. Always look out for the best warranty to cover your investment before buying. Whether for hunting as a hobby, sport, profession or for home security, the thermal monocular forms an essential part of that everyday activity. 

Reliable and trustworthy brands, like the ones in this article, will always offer an affordable warranty on all their products as part of customer care services. Check the type of cover the thermal monocular has to avoid regrets later. 


Let’s look at a few frequently asked questions as I round out this article which I hope has been helpful to you. 

How far can you see with a thermal monocular?

It depends on the thermal monocular’s detection, identification, and recognition range. Some monocular devices can spot an object 3,000 yards away, while others will only positively identify creatures within 100 yards. 

The display type and resolution will determine what you think you see in the distance. There is no definite answer to this question, as thermal monocular features vary. 

Which is better, thermal or night vision?

Thermal vision can easily detect an animal concealed in long grass, but night vision is better at identifying and recognizing objects and creatures because it amplifies nearby visible light. However, thermal vision is better overall because it works night and day.

What is the difference between infrared and thermal imaging?

Infrared imaging gives a single temperature measurement of one spot on the target. A spot pyrometer or temp gun, also known as an IR thermometer, is used. Thermal imaging allows you to see an entire scene in thermal by giving temperature readings of each pixel in the entire image. Warmer objects appear in a different color on the thermal image.
