Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers find the single board computer offers good value for money and appreciate its camera quality. However, the functionality and ease of programming receive mixed feedback - while some say it works okay and is easy to program, others report it doesn't work at all and lack instructions. Moreover, the video quality is poor with blurry images, and customers report issues with connectivity and responsiveness, describing it as laggy.

note: use a DATA rated USB cable - NOT JUST A POWER supply cable...
I had two cables - both for charging things - neither had data - I didn't consider this and nothing would work. I installed drivers... chased after the wrong device... force installed drivers ... crashed windows... reloaded windows... finally asked ChatGPT.... first suggestion was ensure you are using a DATA CABLE... found a data cable for a kids tablet... AND they worked immediately and were recognized by windows... without installing any drivers.

- Reviewed in the United States on June 5, 2025Color: 2PCSVerified PurchaseThe best works as descripted
- Reviewed in the United States on March 31, 2025Color: 2PCSVerified PurchaseThe first twopack of the cams did not work. Code could be loaded, but the cameras were DOA. Amazon immediately replaced these, originals being returned. However, the second pair work perfectly - one as a stand-alone camera; the other has been integrated into Home Assistant using ESPHome for setup.
Using the Arduino 2.4.6 IDE, the code automatically downloaded to the camera with no RST or button pushes required.
Painless...and had the first two not failed, this would get five stars.
The Home Assistant camera was manually set up, using a boilerplate .yaml file from ESPHome, listed below. The initial code is created using the ESPHome Wizard, specifying "esp32cam" from the list. The updated .yaml file is processed using the ESPhome Run command.
Follows is a working .yaml file that allows the camera and it's "flashbulb" to be accessed in Home Assistant:

Have fun! Considering the price, if one has the application, these cameras are the ticket.
- Reviewed in the United States on April 25, 2022Color: 2PCSVerified PurchaseI bought a pair of these ESP32 Cams in April 2022 based on the demonstration at the Dronebot Workshop on Youtube. Those two units worked perfectly and still are performing fine.
Now that their functionality has been confirmed, I decided to go ahead a get a couple more because I have additional uses and a friend is also interested. Sadly, I can no longer recommend these devices from this vendor.
Although I was able to successfully upload the Webserver sketch for the AIThinker version of the ESP32 Cam just as before, this time the performance is unacceptable on both units. Several phenomena occur. Sometimes, the unit just locks up, not responding to any of the settings or even starting the stream. Since these two units are the third and fourth ones that I have purchased, I'm confident that I'm doing everything correctly.
In fact, once the code is uploaded and the IP address is provided in the serial monitor, I tried to "ping" the IP address to confirm that there was a device present. In both cases, the ping was slow and/or non-responsive. Whereas the typical ping time for the other units is typically about 30-50 ms with the previous units, with these two, the pings are hundreds of ms, even over 1000ms. Obviously this causes real problems with responsiveness. (And, yes, all this testing is done with the exact same connection cable, located in the exact same physical location, and connected to the same port on the same laptop.)
Based on some of the reviews, I also tried one of the "old" MB boards with the new cam boards. In one case, it made the performance slightly better, but still no acceptable. In the other case, there was no improvement. And, when I reconnected the older CAM to the older MB, the excellent performance was restored.
The performance problem is with these two new units. They will have to be returned tomorrow.

4.0 out of 5 stars Works well. Good quality camera
Color: 1PCSVerified PurchaseThe 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.

1.0 out of 5 stars Funcionou na configuração de fábrica
Color: 1PCSVerified PurchaseO produto chegou funcionando perfeitamente pela porta USB (a câmera funcionando corretamente e com a rede WIFI aberta pra todo mundo acessar), mas após gerar um novo código (no atual arduino IDE) e depois dar o RESET no "ESP32 CAM" é exibido (pelo Serial Monitor ) o erro 0x105 (erro gerado por não acessar a câmera). Não há suporte e nem forum para resolver o problema. Incluindo que não há informações do "Firmware" e a empresa "Aideepen" não está vendendo a versão deste produto.

1.0 out of 5 stars Bad interference with both unit
Color: 2PCSVerified PurchaseCant use my camera,
i must have my finger below the camera plug at a certain spot for them to run at more than 1 frame per 10 second
If my finger is on that spot i can get some fps, like 10ish at 800x600
One was out of focus i had to remove the glue spot to turn the lens to get it focus
These are both unusable for me
