Your comparison is a true enrichment for the purchase decision. Thank you very much!
This is extremely useful, Thank you. I was going to get the 120 degree but now I will get the 160 degree as it seems better.
Glad it helped
Great video, I like your approach, very thorough. One of my favourite TH-cam channels!
Thank you so much~
Hi, thank you for the effort! It's very nice to see differences at the same time.
Thanks for watching!
You are awesome man. Your efforts 🔥 . Believe me you will be great.
Thx for the test.
Very practical and instructive. A good review prior buying one of these cams.
Thanks for watching! Yeah, I hope it helped.
Nice video, thank you. I am making a camera to monitor my cat's litter box usage. It has a dome lid with a small opening in the top so I need close focal distance. the 160 degree lens looks great for this
hello friend,you did such a great work,i was really trying to improve the image quality and viewing field ..thanks alot
I'm interested in these cameras, new to this but not new to Arduino. Subbed.
Полезное видео! Thanks!
Very useful info!!!
Dec 21 2023 still very relevant. Thank you
Haha. Thank you for your confirmation!
thank-you
Thank you !!
Thank you for sharing!
My pleasure!
really helpful
Thank you for a very good video. I have a question, for example I need to recognize the figures on my counter, but don't have enough space between camera and counter itself. Could you recommend something for me. I would like to have a good picture of figures for recognition and distance between counter and camera should be 2-3 inches.
It'd be good to use a 160-degree fisheye lens, but it can be bad for number recognition because of the severe distortion. You can turn it by force on the basic lens. Please refer to this.

Thanks a bunch this is useful
Glad to hear that.
Thanks for the video!
Have you encountered with OV2640 camera module overheating? I have 160-degree camera, which overheats in less than a minute after using it. I have not glued it to MicroSD slot as you did, just wondering if it will help, if camera is glued to MicroSD slot. Also, have you tried to run these cameras in long term?
My camera overheats and FPS drops down also image gets darker with green/blue color overfilling.
It's common for FPS drops to occur due to bottlenecks, but it is strange for FPS drops to occur due to usage time. I doubt there is a problem with your ESP32CAM board.
Where did you find the Informations about the specs of the built-in lense? I couldnt find any datasheets.
After searching for the model name on AliExpress, I found sellers who provided datasheets. It's really hard to find them.
Congratulations on the demonstration, it was excellent. Would you recommend a complete product like the one in the video, however with a better image, perhaps a well-defined 720p or perhaps an average 1080p.
Check this out. th-cam.com/video/TGqOUVhQQY8/w-d-xo.html
This supports very good picture quality and very fast transfer speeds.
@@ThatProjectthanks
Hello I am looking for spectra data for OV2640, you mentioned the camera is fitter with 650nm IR cutoff. Can you give a reference where did you find this value? Camera datasheet from OmniVision doesnt mention the kind of IR filter the camera uses
I found this on the AliExpress seller's page where I bought it, but it's gone now. Honestly, no one knows whether the values of the IR filter cut off if it's accurate or not.
So I bought a 2-package of the 160 degree with the longer cable.
One works very well, the picture is so clear and the color is better than the little ones that came with the ESP32-CAM boards.
BUT, sadly, the 2nd camera is trash. It just produced a square with random garbage flashing all over the place.
I tested it on other boards just to confirm that it was the problem. It was.
I then put it under the electronic microscope to see if by chance the cable had an issue. Nope.
So then, I applied some heat with my SMD heat pen and for a quick moment, the picture came in, but was very distorted.
So I figured, what the hell. I'll try to reflow it in case it was just a bad spot on the tiny pcb.
Well... I applied the heat and POP!!! The camera sensor element literally popped off and when flying! ROFL
The solder balls on the tiny pcb did seem to not be 100% right, but I can't find the element now to try to fix it.
At least, by seeing this video, I saw that with patience, the little lens can be unscrewed.
So I was able to unscrew that and put it onto the little cam that came with the boards.
Now I have a wider view, which I prefer.
So thanks for proving that the lens can be removed.
what would the wualiy be at around 10mm from the lens to the object ? - I'm designing a Vision based tactile sensor and the silcone needs to be close to the camera lens
10mm? This is too close. You can adjust the focal length by forcing the front part of the lens, but it seems difficult to get it to 10mm. I recommend you find other camera modules for your project.
Have you tried the ov5640 camera?
I'm just trying to add it to my esp32 video recorder.
Hi. Unfortunately, no chance. I'd like to proceed with the project with OV5640 if I have a chance.
@@ThatProject The upcoming arduino-esp32 release, or the 1.0.5-rc1, has ov5640 support. It will give you the nice big bright frame 2560x1920, but it still needs some work - not as quick as the old code for ov2640.
@@jameszahary Sounds good! I wanna try it asap. Anyway, thanks for your information.
Hi, do you know which registers are responsible for triggering an image capture of this sensor?
There's no information in the datasheet.
Unfortunately, I also looked for this and found no information.
@@ThatProject thank you!
Hello! I am working on a project that needs a focal length of something between 5 and 10cm. What is the best lens for this?
A lens with a wide angle of more than 120 degrees may have a short focal length. You can also adjust the focal length by forcefully adjusting the base lens.
HI, what is the minimun focus distance you can get with the 160deg lens ?
I think it's around 10cm at minimum.
Can you show how closely this setup can read QR codes?
I would love to see how well the QR code reading software on an esp32 could read QR codes with these different lenses.
I can't do it right now, but I'll experiment when I have a chance.
@@ThatProject Thank you.
Thank you very much for sharing your information, I am a teacher and I would like to share this with my students, however I do not know if there would be the possibility of being able to share the file of the test table NBS 1010A in high resolution, to be able to print it and perform some tests, Thanks a lot

is it possible to connect 4k external camera like a camera extracted from a mobile? if yes, do i need to modify the firmware of the esp32?
That would be a very difficult task. First of all, it is highly likely that the module of the camera removed from the other device is not the SCCB interface we are using. Connecting this to the MCU and making it work the way you want is close to impossible.

Hello. Please take a look at this post. It would be helpful. www.instructables.com/IO-Expander-for-ESP32-ESP8266-and-Arduino/
@@ThatProject Thank you more!!!
I thought I could make up some cool security cameras with these, but the low level light performance is truly abysmal. Is there an alternative?
The results are not good even if the exposure time is as long as possible. There are night-vision lenses among OV2640 lenses, but it is not recommended to expect too much. Unfortunately, there is no good way at this moment.
Hi, Do you know maybe which lens will be best for use with telescope?
Hello. I think it would be best to use basic built-in lenses without the most distortion. So, you need to attach an additional telescope lens in front of this lens.
Thank you for answer. I want to use ESP in spotting scope. My goal is to run simple stream in VGA resolution on some Android / iOS app that can take snapshots and record video. Your dashcam project would be perfect but I'm runnig Windows :( I know that it is possible but somethimes this device will be use by other people so i'm looking for solution to use ESP with existing app from App Store so that anyone can quickly start to use this device.
Where did you buy them? I need the wide angle lens
I bought it here, but I want you to find the cheapest one.

Hi, I have just a question about the esp32. The microcontroller has a clock ?
I think we cannot find any MCU which doesn't have a clock. Microcontrollers need a clock to ensure timing control. A clock signal is a particular type of signal that oscillates between a high and a low state and is used as a chronometer to coordinate actions of digital circuits. A clock signal is produced by a clock generator.
@@ThatProject The OP probably wanted to know if ESP32 can keep the time - if it has a built-in RTC.
Did you mean if ESP32 can keep the track of the time? It does not have a RTC which could keep time when the microcontroller is powered off but it is very simple to synchronize the time with the NTP server after each boot to always have access to accurate date and time. Just search for *esp32 ntp*
@@ChupoCro I think you're right. Thank you for your comment.
Ok Thanks for your help.
Is any other hardware needed to use these cameras? Besides an arduino.
Ok now I see that ESP32. So that ESP32 can run to an arduino or raspberry pi
@@ysidroespinoza4489 That's all. This camera module includes MCU(ESP32) and OV2640. So you don't need other than this.
Nice video thanks.
but 1 remark, that 'background' music makes you very hard to hear for people with little hearing problems ;)
Just a tip ;)
PL.
Thank you for the tip. I will adjust the volume of the background music.
Agree with Peter thanks for fixing it :D
admin want to ask for this esp32 cam module for what kind of lens support lens?
It is impossible for the system to ask for because it does not know which lens is currently using. What's the purpose of it?
Can anyone tell me what is the largest diameter of the 160 degree lens? It seems that the square base is 8mm x 8mm but is the largest round part 8mm in diameter as well? Trying to make a case before I get the cameras.
The longest part is about 10 mm. Think of it as 10 mm x 10 mm.

,could you share with us how we can have about night vision capability?
Not sure but I'll make another video for the night vision lens sooner or later.
Did you have any link for that:? thanks
I bought them from AliExpress. If you search with OV2640 Lens, most of them will be the same product.
@@ThatProject Thanks!
Any module with a starlight sensor?
To detect starlight, you need to adjust the shutter speed and you need a lens with high sensitivity.
How come your video camera looks so good?
Well, nothing special. Check your wireless environment. If it has a bad signal, the image quality is really bad.
I have uploaded the code but everytime time it shows brownout triger detected and it doesn't shows th ip address please help i have wasted many days but no solution was found
If the problem persists, it may be a bad hardware issue. Please read this post. randomnerdtutorials.com/esp32-cam-troubleshooting-guide/
Rewire it to run on 5v not 3.3v this will fix it (it did for me)
Can we change the camera from 2MP to something more by replacing camera?
As far as I know, there are only ov2640 types of lenses that fit ESP32CAM. If you need a better camera, STM32 or Raspberry pi is recommended instead of ESP32.
@@ThatProject Will we able to do distance detection using the 2MP OV2640

Hey uh... So i got problem, when i changing the camera like you did, i got something like "error calling setsockopt:22" in arduino serial monitor, and not showing any video stream in the web. But when i change the camera that originally included with esp 32 cam its still working. (Showing video in web stream)
My setup(powering the board) is not really that build up for the esp32 cam, im currently powering it up with the usb to TTL thing, because i dont know what else to power this board.
And my esp 32 cam had no vroom kit so its only using esp32 cam ai thinker.
Any solution?
Where did you get the error calling setsockopt:22??? Not sure we are on the same page.
@@ThatProject serial monitor of arduino ide
@@avatar_4real Still, I don't get why you get something like "error calling setsockopt:22". What kind of source code are you running?
@@ThatProject the example, like the basic, not changing anything except "using esp 32ai thinker// has psram" stuff and changing the ssid for wifi and its password.
@@ThatProject chances are the camera is broken during shipping, but idk how to trouble shoot the camera.
And does trying to use dev kit/vroom/wroom what ever they called, or using additional power supply might have a chance to solve the problem?
is the datasheet available for all these cameras?
for some idiotic reason, i've heard the company producing the OV line of cameras keep their datasheets secret.
the result is a needless hassle for hobbyists to use the product.
its a really stupid thing on the part of the company as nobody will then end up experimenting with and using their product.
I don't know if that's true or not, but it's true that the datasheet isn't really available. I sincerely hope they open it for more users.

Is it available?
