IR Dash Cams: Explained and Compared

IR Dash Cams: Explained and Compared

Whether you’re currently a cab driver or you’re driving for Uber and Lyft, chances are, you would have heard about the benefits of having an IR dash cam on board. But what is an IR dash cam, how is it different from regular non-IR dash cams and most importantly, how do you choose one that’s right for you?

If you find yourself asking any of these questions, this article is for you, so let’s get started.

What's an IR dash cam?

Some people call it an in-cabin dash cam, others call it a nightvision dash cam. Either way, the IR dash cam is a two-channel dash cam system that comes with a front-facing camera and a secondary camera that records the interior of the vehicle.

For those who are familiar with infrared security cameras, the concept of the IR dash cam is very similar to that of the IR security cameras, though the architecture of the camera lens and sensors are different - the IR dash cams are not constructed to cover great distances, after all, the distance from your windshield to windshield in your vehicle is typically around 7 to 8 feet, at most perhaps.

What makes an IR dash cam special?

If you take a look at the IR dash cam, you will notice the little lights positioned around the outer edges of the camera lens. These little lights are call infrared LEDs and they are responsible for giving the dash cam its “night vision.” Regular dash cams are not fitted with infrared LEDs.

Why are IR dash cams suited for in-cabin recording?

IR dash cams utilizes the infrared LEDs to invisibly illuminate dark vehicle interiors at night. Traditional dash cams would not perform well in extreme poor-lit environments, but thanks to the infrared technology, an infrared camera can offer crystal clear images even in pitch black environments, making it is the best dash cam solution for rideshare and taxi drivers, or anyone who need in-cabin recording.

How do IR dash cams work?

Unfortunately, there aren't many articles or references on the Internet on how IR dash cams work. But because the concept of IR dash cams is very similar to that of the IR security cameras, we shall take a look at how IR security cameras work.

How infrared security cameras work: Infrared security cameras use built-in infrared LEDs, an IR cut filter and a light sensor to enable video recording in poor-lit situations. The light sensor is used to detect when light levels are low. When light level goes below a certain level, the camera’s infrared LEDs automatically turn on and the IR cut filter is engaged over the image sensor. The IR LEDs then reflect the infrared light of objects within the view of the camera. The IR cut filter allows the camera to capture the infrared light. The result is a black and white video footage. When light levels return, infrared camera switches back to day time mode and captures colour images.

Applying the same concept onto IR dash cams: We know that IR dash cams have built-in infrared LEDs, so it's probably quite safe for us to assume that they also come with a filter as well as a light sensor. In other words, the IR dash cam uses a light sensor to detect the surrounding light levels, as well as an IR filter within the camera to capture the infrared light of objects within the its field of view.

What exactly is infrared anyways?

Infrared is a form of light. It’s light that we cannot see with our eyes. When we think of light, we think of a nice sunny summer day, or even the soft glow of a light bulb. But visible light, the light our eyes see, makes up just a tiny sliver of all the light around us, and infrared light is light that we cannot see with the naked eye. The term infrared means “below red” and everything around us emits some form of infrared light depending on its temperature.

Just like how a flashlight emits light in a dark room so you can see them, the IR camera emits infrared light and when combined with IR sensors, it can read the images within its field of view. Infrared can travel through fog, dust and smoke no matter how thick, making it quite reliable in all sorts of poor-lit situations.

A lot of people might confuse IR cameras with thermal cameras. IR cameras, like the ones used in security and dashboard cameras, are used for capturing images in the dark through the use of a light source in infrared. Thermal cameras, on the other hand, use thermal sensors to capture the contrast in heat in the objects around it to create a heat map.

If IR dash cams are better at capturing in total darkness, can I use it to record the back of the vehicle?

You could, but we would not recommend doing so. IR dash cams are fitted with infrared LEDs, which job is to illuminate the camera’s field of view with infrared light. If the IR dash cam is mounted up against the windshield (pointing through the glass to capture outside of the vehicle), the infrared light is instantly reflected off the windshield, resulting in a reflection or glare that will blind the camera. This will cause your videos to be overexposed or washed out.

Can’t I just point my Super Night Vision 2.0 dash cam around to record the interior of my vehicle instead?

Super Night Vision is not a true infrared night vision. If you park in a pitch black area like a closed garage with no lighting, the dash cam will not be able to pick up anything. In other words, dash cams with Super Night Vision still require a minimal level of light in the environment, whether it’s lights from oncoming headlights or the dim streetlight. We all know how dark it can get inside a car when driving at night, and considering you usually won’t want to have your cabin lights on when driving, you need some sort of light to illuminate the car’s interior if you want to have decent footage Infrared LEDs can illuminate the car’s interior without bothering the driver - because infrared light can’t be seen with the naked eye.

Can’t I just install IR lights inside my vehicle and use a regular rear-facing dash cam as an in-cabin camera?

Technically yes, you can do that. However, again, we do not recommend doing so non-IR cameras are not built with the right sensors and filters to capture IR images properly. You'll end up with video footage that is white-toned, or in extreme cases, white-washed, which ultimately means unusable.

How do the IR dash cam compare?

We carry a few different IR models that caters to various rideshare needs:

*An educated guess based on the faint red glow that the dash cam emits in the dark.

850nm vs. 940nm - does it matter?

Most cameras with an IR cut filter will have a greater sensitivity to 850nm. But note that the 850nm wavelength will produce a slight red glow when looking at the camera, so they might not be as discrete as desired.

On the other hand, the 940nm wavelength does not produce any visible glow. But while it’s more discreet, it comes with its disadvantages, too. The illumination range of the 940nm is 30-40% shorter than that of the 850nm, and this often means that anything over 5 meters begins to blend into the background making the overall image quality not as clear.

So, with that said, for the standard passenger car, the BlackVue IR dash cams are perfectly fine. However, if you have a longer car interior, like a commercial truck or shuttle bus, the Thinkware or the VIOFO IR dash cam might give you better footage of the furthest back of your vehicle's interior.

So, which IR dash cam is the best?

When choosing the best IR dash cam, the resolution and video quality are still the most important deciding factor, so let's not get too caught up in how far a camera can see in the dark.

If you’re looking for a dash cam system that will give you the best front-of-car footage, then the BlackVue DR900S-2CH IR would be our top pick. It is currently the highest resolution IR dash cam on the market, giving you 4K UHD from the front-facing 8MP camera and Full HD from the 2.1MP IR camera.

The front-facing camera offers 160° field of view in its wide-angle lens while the IR camera covers a wide-angle view of 145. That’s more than sufficient for a comprehensive coverage of the road ahead as well as your passengers in the back row. You can operate the IR camera either in Color mode or in Monochrome mode. If you are recording passengers inside your car, we recommend using the monochromatic mode as it offers a sharper, clearer high-quality video. IR Color tends to become quite fuzzy at night, with a peculiar purple-ish tint.

Because the DR900S-2CH IR uses the DR900S main unit, you have access to all the technology that comes with that model, including H.265 video encoding technology, which comes in handy because 4K files take up a lot of storage space. With H.265, a 4K video file can be compressed into the size of a Full HD file, thus freeing up space on the memory card - in other words, you can get by with a 64GB or 128GB microSD card without upgrading to the max. 256GB.

The DR900S-2CH IR also comes with all of BlackVue’s premium parking mode offerings, including region-based motion detection, G-sensors impact detection, time-lapse recording with buffered events - you will need to hardwire the dash cam or hook it up to an external battery pack, like the B-124X.

And with BlackVue Over-the-Cloud (powered by Amazon’s AWS), you can connect to your dash cam anytime, from anywhere. This allows you to enjoy remote Live View, real-time vehicle location, and Push Notifications to your phone as well as back up important videos to the Cloud remotely, and much more - all you need is the BlackVue smartphone app, available in both Android and iOS.

*Important: If you currently own the BlackVue DR900S-1CH and would like to fit it with an IR Rear Camera, please note that there is no port on the 1-Channel to plug in the IR camera - you will need to purchase the BlackVue DR900S-2CH IR and replace the existing 1-Channel main unit. The existing cables and hardwire setup is compatible, so it's essentially a simple swapping of the front-facing camera.

Best Budget-Friendly IR Dash Cam

Perhaps you don’t need the 4K Ultra High-Resolution video quality or the always-connected Cloud features. Perhaps, you prefer a dash cam with an LCD screen or you’re looking for a more transient setup (ie. suction mount). If that’s so, the VIOFO A129 Duo IR would be a great option. Both the front-facing unit and IR dash camera record in Full HD. It offers a 140-degree field of view from the front-facing camera, but the field of view for the in-cabin IR camera has been raised to 160°, as opposed to the 140° of the non-IR rear camera. The larger viewing angle is useful to record all of the passenger cabin, even the front seats, at a close distance.

The IR camera comes with 4 built-in IR lights and you can choose between IR Colour mode or Monochrome mode, or Auto. Again, if you are recording passengers inside your car, we recommend using the monochromatic mode as it offers a sharper, clearer image quality, daytime or night. One thing to note though, the infrared LEDs do emit a faint red glow in the dark.

And like all other dash cams, you will need to hardwire the VIOFO A129 Duo IR or use an external battery pack like the Cellink NEO if you want to unlock the VIOFO parking mode features, which includes motion and impact detection as well as time-lapse recording.

Prefer something by Thinkware? We do have a limited number of refurbished Thinkware FA200 IRC Dual-Channel in store. Thinkware is known for its heavy emphasis on Advanced Parking Mode, and the this IR dash cam is equipped with time-lapse recording as well as Energy Saving Parking Mode to offer extended parking surveillance.

The front-facing unit offers Full HD 1080p video recording, but you only get HD recording from the IR camera. But because it shares the same front-facing unit as the super-popular FA200, it come with all the well-received features, such as WDR (wide dynamic range), Super Night Vision thanks to Sony STARVIS sensors, and much more.

The FA200 IRC is not a Thinkware Cloud-ready dash cam, but there is built-in Wi-Fi so you can still connect to the dash cam using the Thinkware mobile app on your smartphone. And also, just like the VIOFO IR dash cam, the IR lights on the FA200 IRC do emit a faint red glow in the dark.

unlock the power of the cam

Nice solution for fast choice parking power alternatives. Also, I would prefer to have chosen the OBSD adapter version for easiness, but once installed should be fine. The cigar adapter contacts doesn't appear to be enough reliable.

this is awesome product

it relay make the insulation for me very very easy and my customers was very happy because i didn't use any factory wire to connect the dash cam
i give to my customer 30% off from my insulation coast and i save 30 min from my instillation time .

Great camera system

Bought the front, rear and diagnostic port cable (plus their crevasse tool - buy this for sure, I didn’t need the huge install package). Setup was simple and the quality of image is stellar. I personally don’t like all the audio startup info (got old within a day) but will have to live with it, cannot turn it off it seems. For the overall system with me installing it myself, she gets 5/5, could be 6/5 if the audio could be turned off.

easy as pie

so i watched a video as they talked about all the best cameras of all different levels. i chose the best of the best. i placed the order and it was sent to me. literally just that easy

Viofo A129 Pro duo

Hooked the unit to my truck amazing picture quality amazing videos great sound it has it all very satasfied

Thinkware Q800PRO 2K QHD Dash Cam

great price, bought two!

Best mini 128GB at a nice price. Thank you

Overall decent - night is iffy

Overall the camera is decent. The site's service is great. Camera is mostly good. Night time videos has lots of halos/streak

No complaints - ready for another

Quick shipping and all the tools necessary for me to easily install the DR900S. I've had the camera installed in our Equinox now for almost 90 days and I don't have any complaints with it. Changing settings and accessing the footage via wifi is straight forward and was very helpful to review with my daughter after our driving lessons! Now that she has her own car it's time to purchase a second dash cam and I don't have any hesitation in purchasing a second DR900S for it.

so many emails

I bought the suction cup mount 10 days ago and every couple days I get an email about leaving a review so here it is. I have not used the suction cup mount yet or even taken it out of the packaging. I'm sure it's a nice mount but I can not attest to that. I can say when I contacted the website, they got back to me within a day and were very helpful. Would buy from "blackboxmycar" again.

Bought this to replace a different camera

I tried to use the financing option to pay for the camera. Story of my life, I was rejected for some stupid reason. I also had a lot of hours cut from work, so I didn’t get paid a whole lot. I ended up having to make the purchase in full, which left me with very little money. Other than that (I’m not holding it against anyone; the universe hates me lol), my experience shopping here was excellent. I didn’t have to pay any sales tax like I thought I would and shipping was free. The camera also arrived one day earlier than the initial estimate.

The system has been installed in our vehicle for only three or four days. I wanted to get the hardwire kit, but that’ll have to wait until next pay check. The power adapter that was included seems a little questionable. A little green disk lights up when it’s receiving power, which I like, and it includes two USB ports. I assume one to power the camera (duh) and the other for your phone or whatever. It has a three amp current output, but I don’t know how much the camera system uses. I figured probably 2 amps for the camera(s) and the last amp for your device. I didn’t like that it doesn’t list the input current, but that could just be me being picky. The power cord is plenty long enough for us. We installed it so that the cable runs out of the camera and then drops straight to the floor and back up to the power adapter. Absolutely nothing fancy about it. Well, we have a medium binder clip clipped onto one of the hvac vents and then the cable is ran inside of the...the flippy things you squeeze to open the clip.

The rear camera was a different story. I used the included wire clips to take the cable across the top of the windshield (to the passenger side), then I sent the cable over the sun visor, using it as support. Then I used the little hook over the back seat (the one you can put hangers and stuff on) as another support (did I mention this is an 05 Chevy cobalt). I then used another of the included hooks to hold the cable to the back windshield. There was a lot of leftover cable, so I lowered the back seat backrest and dropped the excess behind the seat. I do wish that both ends of the cable were angled or that the connector on the rear cam was angled. I had to place it fairly low on the window to allow the cable to plug in. It would also be pretty cool if there were some bigger cable clips included too so that I could stuff both cords into one clamp. I’d only need a couple though, as the two cables would depart ways early in the routing.

Installing the camera system was easy. Maybe a little too easy. I found a great spot to place the front cam first. It was right behind the rear view, and the mesh allowed me to get the camera installed level. I took the film off the sticky pad and very gently touched it to the glass to line it up before pressing it firmly. I got it just a little bit uneven, but the sticky pad had already taken a strong hold to the glass. It isn’t noticeable at all, which is good because I never got it unstuck to realign. I did take the gps unit off (since it is the base) and mounted /it/ to the window.

The rear cam went about the same, but I did have to peel it off a few times. Once because I misaligned it, again because I couldn’t fit the cable into the port, and yet again for the same reason. Other than those nuances, installation was fairly straightforward. I also downloaded the app (which only has two stars on the App Store!!) to assist in the installation (yay for live view lol). My first issue with the app was when I put my phone into landscape mode. It would seem like the app developers would have accounted for people who rotate their phone in different directions. I flipped mine in a direction the app wasn’t proud of, and I was getting an upside down view of everything. Of course, when I flipped my phone the other way, the view was right side up. But surely that’s not the reason it was given only 2 stars (I’ll come back to this. I’m writing this review chronologically).

The captured videos are massive in size. Almost a half gigabyte or more for a 10 minute recording. The instructions imply the cameras WiFi has a 5G mode. Either this is wrong, or the option is very, very well hidden. It takes about as much time to download a video as the videos duration is (10 minutes for a 10 minute video). It looks crisp on smaller displays, but on a 1440x1080 monitor (which is basically standard these days), the view becomes degraded rather obviously. As with basically all wide-angle cameras, it’s hard to get a good judge of distance and speed, which is part of why I wanted the gps (the leading factor was so that our speed would be stamped in the video, so no one could claim we were speeding or something if something happened).

Next came what I’m going to refer to as long-term testing. When I initially tested a video, there was still plenty of free space left on the included uSD card. My precious camera gave a weird issue. It’s videos ...

Hi Sherri, thank you for shopping at BlackboxMyCar! We're glad to have you as a customer. Come back anytime :)
Great customer service!

I bought this dashcam based on very positive reviews! Well I received the package and realized that I was sent the wrong rear camera, a 1080p as the U1000 two channel comes with a 2K QHD rear camera! I was able to email Jonathan and he verified that I received the wrong camera and will send the matching camera when I send back the 1080p camera! Thank you Jonathan for your assistance! I could have bought from other authorized resellers but I had bought from you because your company is based on customer service! I could have paid more or less but customer service and support is more important to me! Loyalty to service is key! Even though you are located from almost opposite sides of the Country, your customer service sold me to you!!! Continued success!!!

Hi David, thank you for leaving a review! We apologize for the mishap and we thank you for your patience. We're glad to hear that Jonathan was able to help you out with fixing the situation. If you have any other questions, please don't hesitate to reach out to us in the future.
Excellent customer service

Was able to get the right dash cam and the service provided was excellent. The CS representative Katrina was really resourceful. In depth analysis on installation and dash models. Thanks!

Hi Kevin, thanks for leaving a review. Glad to hear you found what you were looking for :) We'll pass on your compliments to Katrina!
It can with stand cold Arctic

I didn't have it that long but it could with stand the very cold weather in Yellowknife NT.

Hi Abdikarim, just the review that we wanted to hear ;) Glad to hear that the VIOFO is holding up.
Excellent Customer Service and Product! Would Definitely Recommend!

Katrina was very helpful when I walked into the store. She spent 5 minutes going through all the dash cams, answered my questions with exceptional product knowledge and recommended which model that I should consider based on my needs. I purchased one of the recommended units and scheduled a hardwire installation. The installation itself was smooth and the technician explained thoroughly on how to operate the unit with great detail. Lastly, they offered a large client lounge with free wifi and Netflix while waiting for the installation. I would definitely recommend BlackboxMyCar in the future. Good work guys!


Hi Dave, thank you for leaving a review. We're glad to hear that Kat was able to help you out with your installation and that you love your A119 V3 :) Let us know if you have any questions in the future, and feel free to reach out anytime!
Great Dash Cam and good price

VIOFO A129 Pro 4K is a fine dash cam. Good quality video and easy to operate. Installation (hard wire) was very easy. I highly recommend this dash cam.

Hi Bobby, thanks for leaving a review. Hope you continue to love your VIOFO!

Have not installed yet as weather to cold to fasten suction cup. Following instructions laid out on installation setup.

Hi Jolanda, thank you for leaving a review! Best of luck with your installation.
Great camera setup and customer service

The customer service was excellent and helped me when I needed to change fuse type. The camera setup is a huge step up from the single channel I used to have. Had it installed a little over 1 week and it has already caught a close call. Would definitely recommend the camera and company.

Hi Paul, thanks for leaving a review and shopping at BlackboxMyCar. Glad to hear that you didn't get into an accident, but may the dash cam continue to protect you!
