Open a door when a face is recognised using the ESP32-CAM
This page contains code and other information for the the YouTube video found here: https://youtu.be/mu3-Sff0B9w
The code is a combination of the ESP32-CAM Face Recognition for Home Automation and ESP-WHO Face Recognition with WebSocket Communication tutorials.
As mentioned in the video, while this demonstration works well, the ESP32-CAM and associated IDF and Arduino libraries don’t match professional face based access control systems. It can be easily tricked and doesn’t check for ‘liveness’. It could be used as a secondary control system to open doors or activate systems for people that have already passed through another access control system.

Hi !
Thankk you for the code , but i have a problem with esp32 cam when i enter access control it freezes then crashes and i have to restart it to work again , can it be a problem of overheating or something else ? any idea to fix this ?
Hi, I was sometimes seeing this. I’m not sure if it’s a bug in the Espressif libraries (I think someone else has reported this) or the camera is just overheating. It seemed random to me.
Hi !
I’m thai and love this project,so plz tell me how to detect intruder in code i’m beginner.
Hi, I’m not sure what you mean but check out the other tutorials on the site and maybe there’s something to help.
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 http://your-ip-address:81/stream ? Might be the camera.
Success, installed 12/1/2019! Did the partition table changes and installed the code from the zip file. Worked great, no issues!
Tried to strip down the code for OTA but couldn’t get that to work, only had about 10 minutes to work on the OTA, I’ll try again later.
Thanks very much for posting this and the YouTube video!
Great! It’s always nice to hear when people have a project working.
Thanks for sharing this. I implemented it and tried compiling the code; but got the following error message:
‘ Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board ESP32 Wrover Module. ”
Please, what should I do to solve this? If I change partition scheme to ”Huge App (3MB No OTA…), it compiles.
Did you create a new partition following this tutorial – https://robotzero.one/esp32-face-door-entry/ ? It’s a big application but also needs the partition for storing faces.
Hi, I’ve followed what you’ve done but when I copy the code in I get the following error:
‘struct mtmn_config_t’ has no member named ‘type’
Any solutions to this?
Hi, Probably the wrong ESP32 Hardware library is installed. Which version are you using?
Hi, sorted that out, yup I was using the wrong hardware. Sorry to ask a question a little unrelated here, but if say i wanted to store the enrolled faces on a google firebase database, which function do I call that contains the blob information?
I’m quite new to this and I haven’t found any help online.
I’m not sure how you would save the face information somewhere different from the flash memory. I don’t know how well the recognition would work if it was testing against face data that wasn’t stored locally… it might be too slow.
hey i want ask about something
I have followed all the ways to be done but I found an error
Camera Ready! Use’http://192.168.1.68′ to connect
[D] [WiFiClient.cpp:509] connected(): Disconnected: RES: -1, ERR:104
[E] [WiFiClient.cpp:392] write(): fail on fd 60, errno: 104, “Connection reset by peer”
[E] [WiFiClient.cpp:392] write(): fail on fd 61, errno: 104, “Connection reset by peer”
can you help me? why show this error
Do you know which version of the ESP32 Hardware libraries you are using? Does it always happen?
Im using v1.0.4
Yes it always happens, and until now it’s still like that
Hmmm. I’m not sure. I thought it was a problem with a previous version of the Wi-Fi library. It works fine on my ESP-EYE so it should be OK on the Ai-Thinker.
I noticed that when I close the browser I see that message which means it comes up when the connection to the browser is lost for whatever reason.
Can you move closer to the router? Might be a power issue as well if the radio for the Wi-Fi doesn’t have enough juice.
whenever i click the ip given in serial monitor it shows like
WiFi connected
httpd_start
Camera Ready! Use ‘http://192.168.43.116’ to connect
[E][WiFiClient.cpp:392] write(): fail on fd 60, errno: 104, “Connection reset by peer”
IT shows an error.Please hep me out
Does it work at all? I guess you are using the 1.0.4 of the ESP Hardware libraries? Can you try moving closer to your router?
Hello, thanks for the great code snippet.
I also faced the same issue, when I entered access control the camera freezes and the system reboots.
I have made a small changes and the issue is resolved.
Under the recognition branch statement above the line of code “if(f)” the piece of code
“Serial.println(f->id_name);” is removed. Before validating the condition the name is printed in serial monitor causing load prohibited error and causing the system to reboot in my scenario.
Thanks again..
Ah.. thanks for pointing that out. I hadn’t noticed that line sitting there. I’ve removed it.
Please help..
Showing error during compliling. It shows “camrea_index.h” no such file or director ”..
“Multiple libraries were found ” for WiFi.h
