Ideas on "remote video monitoring" demo based at ESP32 and ov7670? #67

Greeting! We are planning to have a demo on “remote video monitoring” with cloud. What kind of development board would you like to recommend? ESP-wrover-kit? If yes, could you share us with more ideas? 1) Could you recommend an ov7670 camera? 2) As for esp-idf and Arduino that Espressif links to, are both all good for the implementation? 3) Looking at https://github.com/igrr/esp32-cam-demo/issues/29, esp-idf includes driver and app for ov7670, could you confirm about it? Thanks!

Hi, I am no expert , but from what i can see from the data sheet of the OV7670 i do not see any jpeg output. This would imply that image sizes will be bigger meaning lower frame rate. You might be better of using OV2640.

Thanks for feedback! I noticed that esp-wrover-kit v3 declares the supporting for ov7670 (http://esp-idf.readthedocs.io/en/latest/get-started/get-started-wrover-kit.html). Could you let me know which format of data your board expects to receive from the 0v7670 connected?

Common OV2640 and OV7670 modules have similar pinouts, so both are compatible with WROVER-KIT. As @wdouglas1999 has mentioned, OV7670 does not support JPEG format, so if you need to upload images to the cloud, you might be better off with the OV2640 which does.
