Can you connect to a camera without Nabto?

You can connect to the camera on the local area network (not a big deal, you could this as well without Nabto). However, more importantly, you should now be able to disable WI-FI on your mobile device and access the camera using your cellular data (or connect to the internet via another WI-FI). If it would be of help, you can see the process in the video below.

Can a web server forwarded to the camera?

On both sides, all received data will be forwarded to the other side. This makes it seem to the client like the web server on the camera side is running on the app side, since a get request will be forwarded to the camera side and the camera response will be forwarded to the app side. This way you can use a standard app webview to connect to the web server on the camera (using the tunnel to remotely forward the data).

Can MJPEG be used for streaming?

Since a few MJPEG http demos are out there for streaming on the local network this would also make it easy to do integration. The main job would be to port the tunnel code (which also can be used for tunneling many other protocols than just HTTP).

In Tools > Partition Scheme, select “Huge APP (3MB No OTA)“. Press the ESP32-CAM on-board RESET button. Then, click the upload button to upload the code.

Description

The ESP32-CAM module is a cheap, low power consumption module and could be used as a surveillance camera, but it seems not strong enough to run some heavy computer vision tasks inside, so I have tried making a system to stream the images from ESP32-CAM module to PC via WebSocket, then we can do some post processing there, for example, in this project I do the object detection..

System

After connecting to the same network, the PC broadcasts the UDP package to request ESP32-CAM to start stream the captured images to the remote WebSocket client in PC. The post processing would be done here.

What IP address is ESP32-CAM?

And it’s done! Now, to access the ESP32-CAM web server page, you just need to type the IP address 192.168.4.1 in your browser.

How to connect to ESP32 access point?

The video streaming web server page should load: To connect to the access point on your computer, go to the Network and Internet Settings, select the “ESP32-Access-Point“ and insert the password. And it’s done!

Why is ESP32-CAM called soft-AP?

Because the ESP32-CAM doesn’t connect further to a wired network (like your router), it is called soft-AP (soft Access Point). This means that if you try to load libraries or use firmware from the internet, it will not work (like including JavaScript libraries).

Can ESP work with Arduino?

Yes, that would be possible (a year late haha). The ESP can action when clients connect, there is code for that already supported by the WiFi.h from Arduino. Check out this link: https://www.arduino.cc/en/Reference/WiFiClientConnect

Can I use ESP32-CAM as a hotspot?

In some cases, this might not be the best configuration (when you don’t have a router nearby). But if you set the ESP32-CAM boards as an access point (hotspot), you can be connected using any device with Wi-Fi capabilities without the need to connect to your router .

How many controls does ESP32 have?

The web server has 5 controls: Forward, Backward, Left, Right, and Stop. The robot moves as long as you’re pressing the buttons. When you release any button, the robot stops. However, we’ve included the Stop button that can be useful in case the ESP32 doesn’t receive the stop command when you release a button.

How many GPIOs are needed for ESP32?

Boards compatibility: this project requires 4 GPIOs to control the DC motors. So, you can use any ESP32 camera board with 4 available GPIOs like the ESP32-CAM Ai-Thinker board or the TTGO T-Journal.

How many devices can open a web server?

You can only have the web server open in one device/tab at a time.

What motor driver controls the speed of 2 DC motors?

There are many ways to control DC motors. We’ll use the L298N motor driver that provides an easy way to control the speed and direction of 2 DC motors.

Can you use ESP32-CAM as an access point?

If you want to control your robot outside the range of your local network, you might consider setting the ESP32-CAM as an access point. This way, the ESP32-CAM doesn’t need to connect to your router, it creates its own wi-fi network and nearby wi-fi devices like your smartphone can connect to it.

Do you need an external power supply for ESP32-CAM?

Note: the motors draw a lot of current, so if you feel your robot is not moving fast enough, you may need to use an external power supply for the motors. This means you need two different power sources.

Can you power an ESP32 with a power bank?

To keep the circuitry simple, we’ll power the robot (motors) and the ESP32 using the same power source. We used a power bank/portable charger (like the ones used to charge your smartphone) and it worked well.

What is an ESP32 cam?

More by the author: The ESP32 robot cam is a mobile surveillance robot that can be controlled over the internet. It is built around a standard ESP32-Cam board, plus a motor driver, batteries, power supply board, and motorized platform. It also includes an optional inductive charger so that it can "dock" and recharge itself while remaining connected ...

How many times does the ESP32 camera blink?

The ESP32-Cam's LED will blink once when the camera is initialized correctly, and then twice when WiFi is connected. It will blink 3 times if camera initialization fails, and then reboot. (This happened to me sporadically.)

How to tell if ESP32 battery is charging?

To detect when the battery is charging, there is a connection from the PowerBoost's USB pin to an input pin on the ESP 32. When the input pin reads HIGH, the web page will say "Charging" on the bottom left. I would have expected this pin to be at 0V when not charging, but for some reason there is a small voltage, roughly 1.0 to 1.7V, which is enough to register as HIGH. So the variable potentiometer divides this voltage to a lower level that registers as LOW on the input pin. To calibrate this, rotate the potentiometer to a point where the web page will say "Charging" when a USB power cable is plugged into the PowerBoost, and not say "Charging" when not plugged in.

What happens when the ESP32 boots?

When the ESP32 boots, the left motor turns on (reverse) for a fraction of a second, which can be bad if the robot is on a desk or nearby something. I tried various solutions but was unable to fix this, so if anyone verifies a solution, let me know...

How to connect ESP32 to breadboard?

Attach the wire to the underside of the ESP32-Cam. Plug the Esp32-Cam, the PowerBoost, and the Motor Driver into the breadboard with the PowerBoost at the top , Motor Driver in the middle, then the variable potentiometer, then the ESP32-Cam at the bottom.

Why does my ESP32-Cam say "Brownout trigger detected"?

If your ESP32-Cam often says "Brownout trigger detected" on boot, it could be caused by any number of power-related problems. For me, it was poor wire connections on the breadboard.

Can robots access the internet?

Accessing from the internet. By default, the robot's web page is only accessible from your local network. To access it from a remote location over the internet, you will need to set up a VPN to tunnel into your local network.

Introduction

Creating a locally accessible camera application with the ESP32 is something that has already been done. But why do you need a camera that you only can access on your local network? You can just go look at the thing that the camera is capturing instead of looking at it on your computer or app (unless you have a very big house).

Simple and secure standard surveillance camera

A simple use case could be that you want to make a standard low-cost, uncomplicated (and secure) surveillance camera. Standard surveillance cameras are often shipped with tons of software which must then be supported with updates, security fixes, etc.

Remote video feed in other application

A lot of our customers make video surveillance cameras as standalone applications, i.e. you install it and it streams video to your phone whenever you need to see what is happening on the remote end. However, we see more and more projects where streaming video as part of another application.

Research

ESP32-CAM from Ai Tinker So, we did some research of the market and found that Seedstudio’s ESP32 CAM was a great place to start and which was probably was one of the first ESP32-based cameras out there. It is low cost and has everything on board that we needed including a nice demo.

Overview of the tunnel setup in the camera demo

Since a few MJPEG http demos are out there for streaming on the local network this would also make it easy to do integration. The main job would be to port the tunnel code (which also can be used for tunneling many other protocols than just HTTP).
