ESP32 cam - Capture and send image over esp-now

The idea for this system came from doing a review on this screen, originally I had it connected to an nano. Then I was asked a few time how to connect it to an esp, and also how to show images.
That made me look into how to do it, which is easy and there are a few examples in the library.
Then I found the esp32 that was in the closet amount other “on hold” projects. And then it all clicked together and I knew I got to find a way to use the 2 together. And it’s exactly what I did here.
so now let’s review the hardware, especially this setup. I will cover some of the code and will let you know the future plan for this.

Covering the “how to” of image capture on sep32 cam, showing image on the round cool lcd and using esp now to connect the 2 together.

I love the ESP32-CAM. I am researching how to connect ESP32-CAMs via wifi or ESPNOW such that several cameras can capture an image and transmit to a central ESP32-CAM so that it can save the photo to the SD card. This would give a central location to collect photos from an area. Like a animal refuge area, several trail cams collecting images and sending to a single SD card. Is that a project you might take on for a video?

Loved the video, thank you for sharing your project and code, you mentioned that you are looking at streaming video, so I have joined your channel in the hope of seeing more thanks, Bob in the UK

Awesome project ❤ going to try and make a small pocket camera for a paramotor to see the remaining fuel in flight.

Thanks for sharing and posting a great tutorial

This is great. I'm trying to save the images on the SD-card of the receiver. Instead of using the SD-card as a buffer I want to use SPIFFS.

Wow, this project is super cool! Will try this out soon. Btw just a quick question - approximately what was the maximum size of the image you were able to transmit? Would it be able to handle say 200-300 KB images? Thanks again for this interesting project.

Great video! I have the same arduino board for the display. Would you be able to confirm what pin goes to what? This is the bit that i am struggling with. Thanks.

Awesome project I subscribed. I really want to make a system in which the images captured by the esp32 cam will be transferred to a separate esp32 board and then shown on a screen. but it should be a wired circuit so that it could also work without wifi. please make a video on it.

Nice work and clear presentation- thanks!

Hi, this video is just amazing, have u tested it long distance?

[ismailouafi]

Nice Work, you helped me a lot in my project !!!! .

[smokeysky]

I see this video is pretty new :D
I'm going to mess around with this to get a picture on my Lilygo T-watch 2020 V1 from one of those esp cams.
Thanks!

[desmondlow]

Nice video. However, can you make another video showing how to display what's the ESP32 CAM is seeing with only 1 display? Instead of streaming from another ESP32

[Ibiky_Stern]

If add a speaker, it will be nice door bell :3 ty for video

[NecaVideo]

Nice, video I need to make something similar I want camera to wakeup once a month take a shot of power consuption and send a message to my phone, bonus is od I can make it use SIM card for internet connection instead home wifi and more importantly it needs to support deep sleep mode.

Hey, this video was very helpful. I am currently working on a similar project, but I dont use a monitor. Instead I have to send the photo which was saved as a SPIFF via a telegram bot to a telegram chat. Do you know if this is possible? Could you maybe tell me which telegram bot sending command I need in this case?

[alin-pebp]

hello! very nice and unique tutorial, Thanks for the effort you put into making the video. i'm having some trouble writing the code for a similar application, can we get the code please it would make my life way easier.

So, looks like ESP-NOW protocol has not enough transfer speed for streaming video from ESP32 cam, right?

[berkeates]

Sir I have a problem to run the system correctly. The only difference about hardware is display. I've changed the display class settings into the device's that I'm using. Should I change another thing?? The image is seen from the display but it isn't fill all of it and it is meaningless.

[zaighummohd]

is it possible to send picture via ble/ wifi to esp32??

[summerfun]

Hi, great project. how about use ESP32CAM + TFT, and leave out ESP32? and in this case, is it OK for one ESP32 to handle more than one ESP32CAM? Thx.
