First ESP32-CAM unit to buy.
If you are experimenting with video and using the ESP32-CAM AI-Thinkers' you have made a good choice for an introduction to video processing, and you absolutely should have one of these programmer boards.But you should also have one of the cable converters too since you don't have access to the I/O pins with the cam plugged into this programming unit and the cables allow full access.So, buy one, but you only need 1 (one), then all you need is the camera boards.And try the wide angle lenses with the longer cable.. absolutely worth the upgrade.Nice that it comes with a cam but this should really be slated as a starter kit for working with cams.Note: to remove cam, black flap lifts up like it's on hinges, just be careful, and if contacts aren't clean, a pencil eraser works wonders for cleaning contacts.. tip from an old pro.Have Fun - Kent

Programming board is useful, but issues make this a hard board to use initially
The boards are cheap, which is nice for quickly prototyping systems. The three main lures of this system for me were (1) the programming board, (2) JPEG image format for streaming, (3) PSRAM for image manipulation. I ran into the following issues:(1) Using the programming board, it is easy to program and reset the esp32-cam. However, the programming board does not correctly handle the UART after programming and reset, so I was unable to get an UART communications streaming once the esp32-cam was loaded with a program. I ended up having to get rid of the programming board and use jumper cables so I could use UART communications afterwards.(2) Although this board claims to handle JPEG via the OV2640, it cannot capture JPEG images from the OV2640. It fails every time. Once switched to a different format and then running through a converter to JPEG, I could get JPEG images. This is a significant issue that was very hard to find a solution until spending hours on github issues.In summary, this is a cheap board that is useful for prototyping, but know the limitations, or you will spend hours trying to set it up to function instead of just running with an alternate version.Note that I found these issues to be true for all the boards I tested (4 of them), so it appears to be a consistent hardware issue, not just a problem with one of the boards.

Documentation doesn't actually document what the pin configuration for the camera is.
Tried the AI Thinker configuration in esphome as suggested in some of the end user answer responses and that detects the camera (wrover config did not) but just gives a consistent error after that:[W][esp32_camera:190]: Got invalid frame from camera!Sales email address for the seller just bounces with a content denied error.Update 5/3/23: updating to 4 stars since I did have a faulty unit and received a refund from the seller.

Good camera for the price, has a buzzing sound when transmitting WiFi.
The units are good, they work well, easy to re-program using Arduino IDE. I was able to backup the original firmware and flash it with the example camera server to have it connect to my WiFi. I had to select AI Thinker ESP32-CAM as an option. Only downside is that there is a noticeable sound coming out of it while its transmitting WiFi, so while streaming video its very noticeable. Apparently this is typical of ESP32 units not specifically the camera modules, at least as far as I've seen online posts by others.

Camera model not supported.
One set worked and the other did not . I noticed one camera had OV2640 stamped on the ribbon and the other did not have any camera model stamped on it. I tried both cameras on both MB's and the unstamped camera would not work with either MB's. The working camera would not work on the MB that came with the unstamped camera.Please send another OV2640 and MB replacement.Sense my first review I have changed the rating from two to five. The refunded my purchase and I purchased the same items and they all worked as expected.

The ESP32-CAM works just fine, but ...
Your challenge with the ESP32-CAM module is "how to connect and upload code". It does not come with a USB plug - and even if you plan to use OTA you need to do the initial upload. FTDI is definitely an option, and I would recommend you simply use this - the "-MB" board here is just not worth it.Using ESPHOME there was no way to get the upload to start automatically - pushing reset/EN (GPIO0) buttons on the -MB board doesn't do anything. And the reviews here makes you think the CAM/ESP32 doesn't work. Not the case - but you do need to use the RESET button on the ESP32-CAM module - not the -MB key. Once i used that, the upload worked just fine. Once OTA was enabled, I no longer need the USB board as long as I provide power.The ESP32-CAM isn't the greatest resolution or fastest video processor. It's great taking still pictures and you can take a few a second no problems.

Works well. Good quality camera
The esp32 cam board is good quality. It is easy to flash with the shield and the camera quality is good. I have found there has been a variation for esp32 camera quality.The only thing is that you need to install a driver. The driver that comes with Arduino IDE won't recognise the ftdi chip on the shield. The fix (driver reference and installation) is described in a number of forums and instruction sights.
