**Creating an Online Security Camera with ESP32-CAM**

In this project, we will be creating an online security camera that takes pictures of intruders without any problems. We will use the ESP32-CAM module, which is a small and affordable camera module that can be easily integrated into our project.

To start with, we need to add three lines to use the folder "tmp" for external applications. After creating this folder, we can open developer tools and services to select the camera.snaphost service. Once we enter the correct service data, which defines the file path and name of our screenshot, we can hit call service.

As expected, in our newly created folder, we can now find a picture that is the snapshot we just took, perfect. As a side note, however, the camera does not support recordings, which I otherwise would have also utilized. But nevertheless, next it was time to edit my door alarm automation sequence.

So I firstly added the command to turn on the LED light of the board, followed by the command to take one snapshot, then I let the system wait for 05 seconds and then take a second snapshot. After saving this sequence, I did a small test with my door alarm trigger and it seems like everything worked out just fine, brilliant.

And that brings me to my enclosure for this project, which I ordered this all metal security camera for a pretty reasonable price. As you can see, it already got some damages because I tried to take it apart for half an hour but I had to give up at some point and instead used the always reliable method of commencing hammer time.

The funny thing though was that the camera itself was super simple to take apart. On the inside, we can find a PCB with lots of infrared LEDs as well as the main camera board underneath. At this point, I was wondering whether I could use the infrared LEDs for night vision snapshots and thus I powered the security camera with 12V.

First off, the infrared LED board directly works with 12V and it also detects on its own whether it is dark or not through a photo sensor which basically means we can toss out the camera board without feeling bad about it. The best thing though was that the ESP32-CAM does not come with an infrared filter which means the infrared light was able to illuminate its picture.

So I came up with this wiring diagram to power and control the infrared LEDs through the ESP32-Cam board. As you can see, we will need a boost converter that creates 12V for the LEDs. Then we also need to add a MOSFET which will turn on the infrared LEDs when the GPIO4 of the ESP board gets activated to which the onboard LED was currently hooked up.

So the first thing I did was not only getting rid of the male headers of the board but also desoldering the onboard LED. Afterwards, I connected all of the components to one another according to the wiring diagram I just showed. And at the end, I used hot glue to mount the components inside the enclosure along with the original screw mounting method.

It is important to note though that I also used hot glue to secure the camera right in the middle of the LED ring and to power everything up later on, I also added a chopped up Micro USB cable to the power wires. And with that being said, the online security camera was done but before reinserting it back into its frame, I positioned it on my wall to mark the mounting holes for it and then created them with my drill.

After then adding wall plugs, I secured the frame to the wall into which I then pressed the camera ball. Last but not least, I added cable conduits to my wall so that I could hide the power wire in there and finally powered it all with a 5V power supply positioned in the nearest outlet.

And just like that, you can create an online security camera which takes pictures of intruders without any problems. I hope you liked this project. If so, don't forget to like, share, subscribe and hit the notification bell. Stay creative and I will see you next time.

WEBVTTKind: captionsLanguage: enHi there, you might be asking yourself why I am standing in front of my entrance door. Well, the reasons is that I justed wanted to prove to you that my Intruder Alarm  System still functions without a problem.As you can see I got a notification on my  smartphone because the on vacation switch of the system was turned on  and the door was being opened.And if you are completely confused right now  then make sure to watch my DIY Home Automation Intruder Alarm System video. But anyway, with this system I feel a bit more secure knowing that nobody is inside my apartment. But this message on my phone alone does not really help me when it comes to identyfing an intruder. So in this video I will be using the ESP32-CAM and the housing of an ordinary security camera  in order to create an online security camera that integrates into home assistant. This way I can not only watch a live stream of my entrance door everywhere in the world but the  system also automatically takes photos when my intruder alarm gets triggered. So let's not waste anymore time and let's get started! This video is sponsored by Altium. I recently switched over to their Altium Designer software  and used it to create a couple of PCB s. What I can say is that it might take a bit of time to  get used to, but the software offers pretty much everything you could ever need to design a PCB. So  feel free to test the Altium Designer by yourself by following the link in the video description. The heart of this online security camera is, like already mentioned, this ESP32-CAM  board that you can get for just 6$ from Ebay.This board is basically an ESP32 development board  to which you can hook up this OV2640 camera module. You can actually find the datasheet for the camera chip which comes with plenty  of interesting information on how difficult it is to get all the required data from it. For example the array size of it is 1632 by 1232 which equals a total of 2.010.624 pixels  which look something like this according to the datasheet. So if you theoretically have to sample each pixel individually in order to create a recording at  full resolution with a frame rate of 15fps, then you would only get around 33ns of time to sample  the data of each pixel and thus you would require a clock signal with a frequency of around 30MHz. Of course this was just a simple example and if you want more information  then feel free to dive a lot deeper into the datasheet to get all the juicy details. But what I wanted to demonstrate is that working with such a camera module  requires not only a rather fast microcontroller like the ESP32 but also lots of efficient and thus  not easy to create code which due to the Internet and smarter programmer than me luckily does exist. So for starters let's have a look at the ESP32-CAM example revisited project on  GitHub created by easytarget.After downloading it, I opened  the esp32-cam-webserver file and continued by installing the ESP32 boards for the Arduino IDE. At this point I chose the correct development board and was about to click upload but  then I noticed that the ESP32-Cam board does not come with a USB jack for programming. Instead we have to use such an FTDI breakout board. After setting its voltage levels to 3.3V, I connected the breakout  board pins to the development board according to this wiring diagram. And as soon as I connected the GPIO0 of the board to GND to put it into programming mode,  I hooked up the FTDI board to my computer and finally uploaded the code. Next I removed the wire from GPIO0, as well as the FTDI wires and instead hooked up two  wires to the 5V pin and GND in order to power the board through my lab bench power supply. After then connecting to it by entering the password InsecurePassword,  I opened a browser and typed in its IP Address which sadly did not work for me at all. The only way I got this to work was by using the browser on my phone and only  there I was able to confirm that the camera can take pictures without a problem, awesome. So time to end this initial test and hook up the FTDI breakout board once again just like before. This time though I logged into my home assistant server and created a new node  in Esp Home which I called camera. And after choosing the AI-THINKER ESP32-CAM as the board, I entered my WiFi information  and continued by compiling this first example code in order to download it as a binary file. I used this file and the Esp Home flasher in order to upload the created code to the board  and as you can see that worked out as well because after hooking the board up to 5V power once again  the created node was available online and thus it was time to edit its code. Thankfully the ESP32-CAM is supported by home assistant so all I had to do was to copy a bit  of code, edit the resolution and add a few lines to add the onboard LED to the system. After then uploading this code through WiFi, I added the entities to the dashboard and edited it  in order to display the LED light switch and the camera picture/stream. As you can see the camera can stream a live image of what it is seeing and  we can turn on and off the LED of the board which will come in handy later. But anyway, next we need to use the file editor add on of home assistant  in order to edit the configuration file in which we have to add three lines to use the folder tmp  for external applications.After then creating this folder  we can open developer tools and then services in order to select the camer.snaphost service. And as soon as we enter the correct service data which defines the file path and name  of our screenshot, we can hit call service.And as expected in this newly created folder  we can now find a picture which is the snapshot we just took,  perfect.As a side note though,  the camera does not support recordings which I otherwise would have also utilized. But nevertheless next it was time to edit my door alarm automation sequence. So I firstly added the command to turn on the LED light of the board, followed by the command  to take one snapshot, then I let the system wait for 05 seconds and then take a second snapshot. After saving this sequence, I did a small test with my door alarm trigger and it seems  like everything worked out just fine, brilliant.And that bring me to my enclosure for this project  for which I ordered this all metal security camera for a pretty reasonable price. As you can see it already got some damages because I
