A picture says more than a thousand words. This is why the world is moving away from text to images and videos. We, as Makers, can profit from this movement because we get dirt cheap hardware to play with. And if it works with an ESP32, even better. Time for a closer look.
I am a proud Patreon of GreatScott, Electroboom, Electronoobs, and others.
In this video I will:
- Compare the features of the four boards
- Try to get all of them working. Here we will see that we have to overcome the usual obstacles
- Try to use the new class of I2S MEMS microphones presented in my last mailbag. Two of the modules have such a microphone included
- Try out two sorts of camera lenses

@middelbh 4 жыл бұрын

Dear Andreas, first of all thanks for this overview! I have two remarks, one: I made ths ESP32-cam using an 0.96” oled display and one external button, making time lapse recordings. The images are stored on the SD card. I use the available GPIO pins with some tricks as they are in use for the camera and the SD reader. For example the TXD and RXD pins can be used as GPIO pins, and IO0 can be used as an input as soon as the sketch is loaded, I use it with a button and the touch command in my sketch. On the display you can select wether or not connect to WiFi (I did not yet add functionality to that as I do not have experience with building websites, but maybe somebody can help with that?). Then the user can select the interval for the timelapse on the display, and start te recording. As I am on a short holiday now I cannot give you the sketch, but I will do so ASAP. The second point, I hoped you would give some more info on the little (round PCB) MEMS I2S microphone, how to connect and how to record. Do you have this microphone running on an ESP32? I would be very, very grateful if you have some more info on that! Regards, Hans

rear view and the like cameras on vehicles are generally analogue to overcome the delay inherent in digital vision systems. It would be useful then to characterise these boards in terms of latency. Are any good enough to be used for vehicle rear vision? Also, I guess we need a maximum number in ms latency that will not interfere with real time vision applications to compare the cameras against.

Very useful video, thanks! I've been thinking of getting some of these boards, I have some project ideas very relevant here South Africa: 1) Intruder recognising security cam: Take pictures or a short video when sound is detected, and send it to a PC/Raspberry Pi/cloud service to do image classification to detect if a human is in the image. It then sends a alert and photo if a intruder is detected. Way less false positives than a passive security sensor. We have a very high violent crime rate, so it could literaly save lives. 2) Wildlife camera: For wildlife research in game reserves, it is a much cheaper alternative than commercial trail cameras so many more of them can be deployed. Photo's can be stored for later access or sent it to a GSM-wifi gateways. It can also be used to prevent human-animal conflict, like detecting when a lion/leopard/jackal comes close to livestock enclosures and send alerts. Both of the above ideas can be tested in my immediate area, and I also have access to world class game reserves if you're interested, so let me know!

I like the idea of using a camera as a user input device… There are many ways it can be done, using just that as your premise. One way I've considered, is using an object with a QR Code printed on it, which the camera can track. You can even use multiple QR Codes with unique IDs encoded in them. …Three things to consider, though, are the latency of the camera and video processing steps, the FPS, and the pixel count (or resolution). Latency will lead to an experience that feels slow and unresponsive. Low frame rate will lead to motion tracking errors with fast movements. A low number of pixels will mean less detail, so you'll need to compensate with larger QR Code labels. Anyone is free to use these ideas, by the way! I kinda hope that someone does something with it.

For face recognition and wifi you may be more interested in the K210 boards. I think there is also an M5StickV+ coming up with WiFi as an upgrade to the M5StickV (careful the mic does not work in that one)

nice video, i was waiting for something like this for long time! I want ask, are any of these cheap boards suited for primitive monitoring of my house, streaming over home wifi to mobile?? nothing HI-res, just see, if people or cars are moving around etc, are these capable runing from bateries only (18650 i gues)?? how long if yes ? I have raspberry pi zero with 5mpix camera with motionEYEos, which work pretty good i think, are any of these boards similiar to this in image quality or capabilities ?? Is better use theses, or buy (outdoor) ip webcam and use that??

@fuzzie4755 4 жыл бұрын

The battery power will maybe work for an hour or so. Nothing that works for normal interaction. The video stuff quite takes a lot of power. If you just wake up with a door ring it might work better because the you always need only a few seconds full power.

And is there anyone who used one of these products in such purpose for long term? Thanks one again.

Thanks, this looks promising. In our visitor-center we want to make a couple of birdnest-camera's. Until now I thought we would need pi-zero's with a camera module to stream to a central pi3b that is attached to a tv. But I don't know yet if it is easy to add audio to that stream. These esp-cams seem to be made for that. Do you already know if it is possible to use such a device to stream audio and video together in a decent quality to a central raspberry pi? Or do you think it would be better to use the pi's with cam modules and an extra microphone for that?

That's how I, after months of googling figured out it could be done with a couple of pi zero's and a central pi 3b+. None of the video's I find of it have audio with it tho. (And birds do make noise so it would be great to not only see them in the visitor center). I had hoped that since you made that video some time ago you had made progress on that subject.

In 3 days I went from blink LED to TUNIOT to ESP32 cam working after about 24 hours of fighting.

Would you recommend using an ESP-CAM, and offloading the pattern recognition to a tensorflow server? Is there a solution which does not depend on an external server or more expensive board with DSP? What if we only wish to process audio locally?

IoT Update: I've found a keyword spotting engine that runs on the ESP32 [1]. The engine only detects the phrase "hi lexin", and is proprietary. However, this paper [2] shows us how to detect "hey cortana" on a 48mhz microcontroller with 32kb ram. And their code is open! The secret sauce is neural network quantization [3]. It lets us compress a floating point DNN into one that uses only bitwise operations (and ~100x less memory). (This paper has over 1000 citations, and is quite remarkable.) tldr: There is the smallest glimmer of hope that my project can run on a $14 M5Stick-C Pico or a

ESP32-CAM and others doesn't have enough IO if you use the SD card. If you want to capture an image and save if to the sd card you'll need a second µC. The second µC will tell the ESP32 to take an image via Serial comms. You can attach a sensor to the second µC as well.

I am working with cheap esp32-cam for a while now. They do have some odd quirks e.g. on at least two of my devices the camera stops working if it doesn't touch the sd card slot ... I have no idea why. I also can only program it if it gets 5V but not 3.3V. Multiple IO ports accessible don't seem to be usable e.g. IO16, Programming via Wifi doesn't work properly, ... My plan is to build a security camera with wheels on it that either works like a remote controlled car or like a gondola on a rope having over my garden ;)
