# ESP32-CAM Video Streaming over HTTP and Face Detection

Today I had some experience with ESP32 camera module. I was really surprised that it can stream camera over HTTP quite well with a very cheap price. I had an ESP32 CAM board + a USB programmer from my friend to upload program onto the chip and I decided to write this note to introduce this board to you.

**This is my ESP32 and the programer board (CP2102):**

You can buy a pretty cheap ESP32 module with a convenient programer with only 113k VND ($4.9) [here](https://shopee.vn/B%E1%BA%A3ng-M%E1%BA%A1ch-Ph%C3%A1t-Tri%E1%BB%83n-Wifi-Bluetooth-Esp32-Cam-Mb-5v-M%C3%B4-%C4%90un-Ov2640-Ch340G-Support-picture-shooting-Support-video-preview-i.213820428.6365106948).

After having all the items, you can use the instruction [here](https://www.nutsvolts.com/magazine/article/build-a-video-camera-using-the-esp32-cam-board) or [here](https://randomnerdtutorials.com/esp32-cam-video-streaming-face-recognition-arduino-ide/) to setup our ESP32 as a WIFI camera. This tutorial will help you setup a WIFI hotspot (access point) on your ESP32 and stream camera through HTTP connection.

### Streaming camera with resolution 800x600

### Face detection test

### Think about the applications

We can think about a lot of applications we can do with this camera board\:

- Surveillance camera/robot.
- Face detection and recognition for door lock (or how about a treasure box?).
- A mini self-driving car with processing threads on your laptop.

Maybe I will revisit this board again and do some projects in the future.
