ESP32-CAM Face Recognition Open Door Lock
ฝัง
- เผยแพร่เมื่อ 13 มิ.ย. 2024
- Use an ESP32-CAM to unlock a door when a face is recognized. Create a name based access control system with face recognition using an ESP32-CAM and an electric lock.
From release 1.0.5 the custom partition table can be uploaded with the Sketch and doesn't need to be added to the IDE. This makes this project much easier. The section 2m41s to 4m08s can be ignored.
Face recognition doesn't work in hardware libraries 2.x.x for this device. Please use 1.0.5

Just made this - works perfectly - very well explained mate!!
Beautiful work thanks for making the material available and your cod we are working here very slowly !!
Very clearly explained, I've subscribed!
great work.
I tried
it works perfectly with esp32 version 1.0.4.
Thanks a lot !
For all the people who look how to straight start a face recognition when the module is power on you just have to change in the code : typedef enum
{
START_RECOGNITION,
START_STREAM,
START_DETECT,
SHOW_FACES,
START_ENROLL,
ENROLL_COMPLETE,
DELETE_ALL,
} en_fsm_state;
I think that this just means that when the browser connects you don't have to press the 'Access Control' button to start face recognition? You still have to connect to the browser so the websocket connection is active.
The best teacher ever. You did a amazing job!
Everything worked for me perfectly. Thanks for share you knowledge 🙏🏻
Let me ask, do you have a sketch that works automatically when starting the controller?
Great video like always
It worked perfect, thanks a lot!!!
Can use esp 32cam without wifi?? And save the data face recognition in sd card??
Congratulations, this project is really useful. You would have something with mqtt working together. Using mqtt I could easily work with Openhab. Thank you!
Great job, i already try work fine. can it work without the streaming? I meaning only camera and relay
thank you, very good!!
Great project!
Excellent project. Working fine. Just I connected ESP32 and executed the sketch. I didn't change or create a new partition scheme. By default it has been set as Huge App in the IDE. I just connected an LED to test the recognition result. It works well.
I have a pixie2, so do I need this to use for my robots Vision? Nice job.
thanks for the great video. but can ask one question about this program. What method is used in this face recognition process?
Hi! I managed to get it partially working. It detects at first then a few seconds later the ESP32 disconnects. Also, the output pin does not seem to output a signal. Are you using an original esp32? I'm using a clone from aliexpress (the Rx and Tx pins is reversed otherwise it won't upload the sketch).
I've used a 100uf Cap and an external power as well.
@@webslinger2011 Normally RX on one device is connected to TX on the other. Might be a power issue, might be wifi. Does the CameraWebServer example work OK?
@@robotzeroone Other than the Tx and Rx pins were switched. Camera webserver works fine. It's when I try to activate a pin for the optocoupled relay that's when it resets/disconnects(happens even without anything connected to the output pin). Using your face recognition code.
@@robotzeroone What usb to serial programmer are you using? Mine is an FTDI FT232RL USB to serial IC from DFrobot. Maybe I could try a CP2102?
I'm using a CP2102. I remember the FTDI I tried didn't work when I started with these cameras so I've not tried again since. Try changing the output pin. I found 2 and 12 worked. Do you have a card in the reader? Also if you look in the serial monitor and installing the ESP Exception Decoder might help.
Can you make another video like this where there is a second esp32 that activates the door lock when the one outside sees the face? This way someone can't just jump the relay from the outside.
in this flash memory or Face Recognition partition (2621440 bytes with OTA) how much face data can be stored?
Hey guys i need help for my project i want to create a door control with face recognition using esp32-cam, and also it can capture motion using motion sensor and send the picture using internet to the phone app...
Hello, I need help. Maybe you can recommend me something concrete or at least make some suggestions in both the HW and SW parts. Any help is welcome. I need to set up a kind of surveillance/streaming system for a project at my school. I would very much like to do it with something like ESP32-EYE or ESP32-CAM. My intention is to stream (or as close as possible) on TH-cam or FB directly from the module. I am not sure if that is possible and how to do it. I am very tight on time, and I don't have much money for testing either. I know that you have a lot of experience and have tested many modules. Please, which ESP module/camera/software could I use for that? Thank you very much.
Hi, does the face recognition also work offline (when no browser is connected)? Or is the ESP32 CAM Arduino support limited to the webserver feature? I've only found offline examples for ESP-IDF
, but not for Arduino...
Hi, This one will work without being connected to a browser: robotzero.one/esp32-face-door-entry/ You need to be able to add the faces while using the browser but you could then run a cut down sketch to not use Wi-Fi at all once you have faces.
I'm using board version 1.0.5 and partitions.csv it can store how much face data sir? and how to delete the face data?
hello, thank you very much for the video, the program runs and sends it to the esp32 but the serial monitor does not show me the ip
First of all congrats for this great work!
I'm facing an issue on this project...Everything was running perfect until the last couple of days i was no longer able to stream from the esp-32 cam, as a result it couldn't detect or recognize faces anymore. I updated the boards and libraries, i even tried it from different computer and browser but still the same. I still can browse into the web UI but it won't stream any image from the left window. I tested my esp32-cam board on other projects and it's fully functional. So, any thoughts what's causing this issue? Thanks!
Does the camerawebserver example work for you? If you load that up can see the video at your-ip-address:81/stream ? Might be the camera.
#include"soc/soc.h"
#include"soc/rtc_cntl_reg.h"
void setup(){
WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG,0);//disable brownout detector
}
This will help!
Nice one sir
everything running fine but when i opened webserver, no streaming is there. I am getting "Failed to get the frame on time!
" this message on serial monitor.
Hello i got error like this
"FaceDoorEntryESP32Cam:329:86: error: 'recognize_face_with_name' was not declared in this scope

hi, I just want to use ACCESS CONTROL for my project. Can you help me to modify code?
Good job sir fantastic projects
Sir how much distance operated in mobile
Hello, I was wondering how I could go about drawing squares around peoples faces as I wish to repurpose this for a slightly different purpose. Any help would be appreciated!
I took out that code to try and make things less complicated and maybe run faster. I think the boxes are still there in some of the other tutorials on my blog.
thank you
Thanks a lot
sir, can you add flash and stop camera ???
Thank you so much MR. Robot Zero! Really nice work! How can I change the HTML to another language?
I don't understand. The HTML is used by the browser to display the interface.
@@robotzeroone hello mr. robot zero, is the web browser ide made by you or is it built-in by the Arduino program? thanks alot
Very good ! It is the only video on esp32cam with such utility. It shows that there is a lot of knowledge .
I don't know English and it is still perfect. Please I want to know what you mean when you say (IDF versions).
You have to modify library code to detect life and not fool the system with photos?
I have the ArduinoWebsokets library in version 0.5.3, esp32 1.0.6 and my Arduino ID 1.8.16
Greetings from Argentina.
Thanks! IDF is this docs.espressif.com/projects/esp-idf/en/latest/esp32/ To have liveness detection you need a second camera for a 3D image or an infrared for heat. Some systems might use face detection on frames in a video. Not possible at the moment with the ESP32 though.
That's awesome , but i have some questions
1-Can we add a virtual unlock button in the interface or whatever as a second way to unlock ?
2-Can we use 1 or 2 servo motors instead of that lock - i'd use 'em to power manual deadbolt lock-
3-Can we make use of the open Cv liveness detection
One and two are possible. You can code websockets for communication in both directions. Other tutorials on my blog might help with that. OpenCV doesn't work on the ESP32 AFAIK you would have to use the video stream on another device.
Hello. Thanks for sharing your knowledge with us enthusiasts. I have a problem and would like your help. The scket ran fine, but in time to capture the image of no face detect in google chrome. Then I close the page and open in Internet Explorer, the name is saved and I can open the door. But if I restart esp32cam add the names
Hi. Can you explain that again. I don't understand.
thankssss for such an informative video... I'll try it out
Thanks for the great tutorial. What is the maximum number of faces that could be registered? Can we move the registry of faces to SD card so we can handle more users??
HI, Check out the issues here - github.com/espressif/esp-who/issues You should find the answer to your questions.
It doesn't detect the face even i enable the recognise and detect button...what can i do
Can I know the method used in this project either it is Cascade Classifier method or any of this techniques Linear Binary Pattern, Eigenfaces, Fisherfaces?
The technical information can be found linked from this page - github.com/espressif/esp-face/tree/420fc7e219ba98e40a5493b9d4be270db2f2d724
May I can try it
Hello MR. Robot Zero, I really appreciate your work on this tutorial. I did the implementation as in your tutorial and everything works fine, faces are enrolled OK and faces are detected OK; However, if a new face (one that is not enrolled) is presented to the ESP32-CAM then sometimes the system detects it as one of the enrolled faces. Is this the bug that you mention at 9:16 of your video? Is there a fix to this problem?
The problem mentioned was with an earlier version of the ESP32 Hardware library. In 1.0.4 it's fixed. If you are finding it detects different people as the same there's a setting that can be changed but without looking into it I think it might be only available in the IDF version at the moment. Checkout FACE_REC_THRESHOLD here: github.com/espressif/esp-face/blob/master/face_recognition/README.md
@@robotzeroone THANKS for your response. I find a FACE_REC_THRESHOLD, in the fr_forward.h file. It looks like:
#define FACE_REC_THRESHOLD 0.5
I changed this to #define FACE_REC_THRESHOLD 0.7
It is working now but I cannot yet confirm that reliability has improved. I am going to test during the next few days. Meantime, if you have any suggestion, please let me know.
Thank you very much sir for this wonderful video, but I have a question pls how can i change the code so that it will not capture one face with two different name, so that the system will prompt you that the face is already captured and has so and so name. Thanks you are my best mentor in IoT stuffs
You would have to rewrite the code to check if a face is recognised before running any other code.
camera_pins.h: No such file or directory I am getting this error
Hi, I would like to know the way to upload a image from esp32 camera to a webserver or google drive. Could you make a video about that?
Hi, I have a tutorial on my blog that might help with that - robotzero.one/time-lapse-esp32-cameras/
Cheers for this guide, persistence was a big help. however it seems very laggy and slow, and is it possible to use without the browser connected? Don't want to have to have something logged into it all the time
It's slow because running the face recognition really taxes the ESP32 processor. This version you can disconnect - robotzero.one/esp-who-recognition-with-names/#comment-43712 Or you can use the version in the video to set up the faces and then this one - robotzero.one/esp32-face-door-entry/ without Wi-Fi to run it
Excellent video. I'm a Brazilian student and is i'm realizing a similar project. I would like to know what the names of the components and schematics used, because i only know the ESP 32 - CAM. Thanks!
Hi, This page has more info on the items used: robotzero.one/esp32-face-door-entry/ The door lock was one like this: es.aliexpress.com/item/32949292074.html
sir good day just asking why is it that the face recognition partition scheme in my IDE is not showing even if i follow the direction you gave
Hi, Did you restart your IDE after changing the boards.txt file?
thanks..
I have a question, if i want to make the relay on for more than 5 second, what line of code do i need to change?
long interval = 5000; // open lock for ... milliseconds
Hi sir, great video I really enjoyed it but I have a question. How do you open the door in case that the light went out and in consequence the wifi stops working? how would you open the door in this case? greetings from Ecuador
Hi, this tutorial doesn't have the wifi- robotzero.one/esp32-face-door-entry/ so will work just running from a battery.
Great...👍👍👍
when face detection and recognition turn on, why esp 32 cam is black and serial monitor is martix3du item alloc failed?

Hello sir, wonderful tutorial. Just want to ask, can I extract the sample captured? will it be in picture format? if can, do I need to change into SD card partition or can use your created partition? sorry I a bit new in this area.
Hi. You want to save the data captured for the face? I've not done that yet but I imagine you can copy it off the fr partition to another location.
@@robotzeroone I see, so just to be clear. the partitions stored the face/user data but in other type like hex or byte is it? sorry I still dont know what is the partitions is.
@@said7176 The face data is a mathematical representation of the face. These are stored in the fr partition but I don't know how this is structured as a file system. You would have to look at the code in the Espressif IDF to see how it's done. Not really beginners level stuff.
@@robotzeroone I see, Thank you so much for the explaination. Help me understand further more. Thank..

@@robotzeroone. Thank you very much. I am someone who admires you very much
good video ,do we have to press every time ACCESS CONTROL to get started when ever device restart
At the moment it doesn't run autonomously. I'll be creating another version soon.
@@robotzeroone your code is great only issue is it dosnt work at restart unless press Acess Control again.Would be waiting for your new version.
thank you, sir! Could you tell me where is the face data finally stored?
It's stored in the 'fr' partition in the flash.
Hai sir, I wonder if i can make the system recognize only 1 face in all faces in the db. For example like hardcode where face_id == 1, which system only recognize user where not the other. But it seem didnt work for the face_id. I also cant figure out how the enroll system save the face_id. Do you know what the return where I can make the == 1 to bind only 1 user? thank you..
Did you see the other tutorial here: robotzero.one/esp32-face-door-entry/ it's less complicated if you just want one face. Maybe the line if (matched_id >= 0) { could be changed to ==1?
Does Enroll images saved even after Power ON and OFF of ESP32....?
In this project, yes.
HELLO robotzero, please i am having this error 'face_id_name_list' was not declared in this scope what can i do please
Hi. Probably you need to update the ESP32 hardware libraries to a newer version. Tools > Board > Boards Manager
Hey sir, can i connect this to lcd, so when it esp32cam detected someone, example me : nathan, my name will shows up in the lcd
Hi. Check out this video for connecting an LCD - th-cam.com/video/j8lVFmjAARA/w-d-xo.html You should be able to combine the code to do what you want.
Not detecting the face in google chrome. I ask to capture not create user. Then I close google chrome, when I open IE with ip, the name is there. I can open the door normally. But in IE also can not trigger users. When I reset esp32 cam the names disappear.
Something isn't set up correctly. Did you create the new partition? Browser doesn't affect it. Everything is done on the ESP32.
Just in case there is any possibility of performing facial recognition, but without the need to access the web server?, that is, that the esp32cam works independently of a web server, that its function is to recognize the face and open the lock.
Yep. Here's a version without the webserver: robotzero.one/esp32-face-door-entry/ You can mix and match from various tutorials on my blog.
is the recognized face saved permanently? i mean did we lost the recognized face when we turn off the camera?
In this project the face is permanently saved.
why did I upload the problem failed on the esp32 board even though it's the same as the video
Try another sketch. Start with something basic to make sure the device is OK.
hello sir, while i compile the program, fatal error: camera_index.h: No such file or directory

Which version of the ESP32 Hardware Library are you using?
Hi, thats a great video and i want to use it for my final project, what do i do if my arudino ide is version 2.x.x and above?
Thank you vey much i hope for an answer
HI, I think it will work with those versions of the IDE but the ESP Hardware library has to be be 1.0.4 or 5.
yep i managed to do that but i cant see the partition scheme for some reason@@robotzeroone
Can you change the board to AIThinker ESP32 Cam? Maybe that will work with Huge App selected
when i select ESP32 CAM it wont let me change the partition scheme at all@@robotzeroone
I'm using the version 2.0.0 of the Arduino ESP32 hardware , what csv partition file have i to use ? With the csv file for the 1.0.5 version you provided, there is no streaming after connection to the web server.
I don't think the face recognition works with v2. The built in camerawebserver example wasn't working last time I looked.
@@robotzeroone Thanks for the information. I'll go back to the 1.05 version.
By the way the camerawebserver example is working flawlessly with the 2.0.0 version.

Great project well done
Dear Robotzero.one , Thank you for sharing thsi amazing project. You have done a Great Job ! Everythings works fine and you explanation was perfect.
For what I have seen at the beginning of the video , you have the ESP 32 CAM installed right at door entry, but I am wondering how do you manage the browser page.
After faces recognition, I would like to make it works as a stand alone device, without any PC connected that is needed (or I am wrong..)
Is that possible ? Do you have some suggetion to do these SW modification ?
Thanks a lot anyway for this project!
Cool. I'm glad it's working for you. This one will work without being connected to a browser: robotzero.one/esp32-face-door-entry/ The easiest way is to have one sketch to add faces and another you flash that doesn't need browser to be connected. Alternatively, you could probably do one sketch with a timeout so after five minutes it stops the websockets connection and just runs face recognition.
@@robotzeroone Thank you for your kindly reply. I will go for your suggestion to have two source codes.

if you have solution please tell me . because i use this project for last exam in my college
I think this is Wi-Fi related. The ESP32 thinks the browser has disconnected. Can you move closer to the router?
i try connect with sit in front of my wifi router the result is same sir. I change the another browser and and use my hotspot in my phone still same. If i klik f12 in browser some problem has show in console. "Websocket connection to 'ws://192.168.1.7:82/'failed :could not decode a text frame as UTF-8".

Hello can i use servo motor instead of the lock used in the vid
Hi. You should be able to. Check out the servo tutorials on my blog: robotzero.one/?s=servo

Are you using 1.0.4 of the ESP32 hardware libraries? What is the error? Check the comments in the blog for more help.
Can we make a buzzer sound for faces not recognized
You would need to change the Arduino code a bit to have a face detected but not recognized be sent as a Websocket message. On the browser you can make a buzzer sound with the code starting at line 156 github.com/robotzero1/esp32cam-access-control/blob/master/HTML_interface.html
Great video! Would it be possible to pass MQTT messages to a broker when ever a face is detected ? That would be great!
A tutorial for Blynk - robotzero.one/face-recognition-with-blynk/ or if you want to use the code in this video you can replace the open_door(client); with something like send_MQTT(f->id_name); and do your MQTT stuff in the send_MQTT() function.
robotzero.one thanks! I’ll first try to edit the code of the esp face recognition relay article! That looks easier to me 😅
Your video is great. I starts a project based on your videos a spy camera robo. But problem is the robo moves by blynk app and esp32 cam video stream control by pc I want just one screen control movement and video streaming but I don't know how to do it so plz tell........ And you can tell me what I can do Extra thinks to make more advanced this robo. Plz reply
@@souravpatra0175 Probably the best option is to use this tutorial as a base: robotzero.one/esp32-cam-rc-car/ and use the two pins to control two motors for left and right like on a tank.
So basically somebody could walk up and cut the wires and connect a 5V across those to open that door?
Yep. It's just a demo to show the circuit.

Is it possible to run the recognition without opening the webpage?
I changed the code already, so now the detection starts instant, when power ist connected.
but before I have to open the webpage and I don't want that.
Check this tutorial for a version without the web browser. robotzero.one/esp32-face-door-entry/ Maybe you can load up the faces using the tutorial above and then switch to this one using the same faces.
@@robotzeroone I will try it, thanks for the answer!
this only works when the browser is enabled. can it work alone?
Best way is to use two sketches. One to grab the faces and then another that runs without the Websocket communication. I have other tutorials on my blog.. something there might help.
Congratulations for the tutorial, I followed everything clearly explained, but loading the http page only the part of the controls is visible but the streaming image of the camera is not visible

How hard or expensive is it to get liveness detection. I want to use it on a front door of a house. To open while walking towards it? Thanks
With the ESP32 it's going to be difficult. It's just not fast enough. There's this product (hard to find outside China though) - aliexpress.com/item/4000070597568.html?spm=a219c.12057483.0.0.5f1057ab3Yex4z that uses two cameras. Or with a PC (maybe Pi) something like this: www.pyimagesearch.com/2019/03/11/liveness-detection-with-opencv/ This one will probably be the best if you want to capture you face as you walk.
@@robotzeroone Yeah I think a PC would be the go. I want to connect other things in the house aswell, but the door system should be independent so it cant be hacked. The problem is I dont know how to code.
@Zed If you've not ever coded then this is jumping off into the deep end! The second link pyimagesearch has loads of tutorials but you'll probably need to learn some Python first. Loads of tutorials on TH-cam for that.
Did someone work?
Can it detect and open door for people with face mask? We are in pandemic time now.
Nope.. it takes measurements on the persons mouth so it won't work if it is covered.
Is there any possibility of doing the same but with an esp wrover cam card?
That is, wouldn't it have conflicts with some libraries?
I just realized that I'm going to be missing pins to place my fingerprint sensor. This is a double authentication project that I want to do, incorporating fingerprint sensors and more facial recognition.
