Where you able to use OTA with this device?

Hi,
I have used OTA sucesfully with the esp32-cam but select the "ESP32-cam" board in the Arduino IDE, use "ESP32 Dev Module" and make sure PSRAM is enabled

Re: problem with settings on esp32-cam module

In case anyone else has this problem I have had a bit of a breakthrough. I think my problems all along is the camera has auto gain and exposure which I am fighting when I try to make adjustments to the image. It is not very clear what many of the settings actually are/do but I now have it working us...

Re: ESP32-CAM Problem with not enough pins

You can use the sd card in "1 bit" mode which means you can then still control the onboard led (gpio4) when using an sd card?
gpio12 and 13 are then not used by the sd card

Re: problem with settings on esp32-cam module

Basically what I am asking is, why does this work? sensor_t *s = esp_camera_sensor_get(); s->set_brightness(s, 0); fb = esp_camera_fb_get(); but this stops both brightness and contrast adjustment working at all: sensor_t *s = esp_camera_sensor_get(); s->set_brightness(s, 0); s->set_contrast(s, 0); f...

Re: ESP32-Cam and SD Card

Hi, Just wanted to confirm that if you start the sd card in "1 wire" mode with: SD_MMC.begin("/sdcard", true) you can then still have full control of the illumination LED :-) I have also included "pinMode(2, INPUT_PULLUP);" - I have not yet tested if this is actually needed on this board? I have jus...

problem with settings on esp32-cam module

I am having real problems trying to configure the settings on my esp32-cam modules (using the ov2640 camera). I seem to only be able to set/adjust one of the settings, if I try to adjust two or more it stops adjusting most / any of them? I have tried everything I can possibly think of but to no avai...

Re: esp32 camera: motion detecting security camera

In case anyone is interested, I think I have it pretty much finished now (I keep thinking that then coming up with another idea - lol)
You can see a video of what it does here: http://alanesq.com/temp/CameraWifiMotion.mp4

Re: esp32 camera: motion detecting security camera

Here are a couple of screen grabs from the web pages it produces: http://alanesq.com/esp32/2.png http://alanesq.com/esp32/1.png BTW - The web response can sometimes be a bit sluggish, this is something I am looking in to? I did discover a lot of this can be caused by poor power supply to the board

esp32 camera: motion detecting security camera

Hi, I have been working on an Arduino sketch for using the cheap ESP32 camera modules (£5 on eBay) as a security camera. My basic idea is to have it detect movement (by the camera image alone) and when it triggers send me an email which includes a captured image. So far I have it in a basic working ...
