Can we use esp32cam like this. I want connect esp32cam for live streaming and photos from anywhere. Like this I want to make a html page for live streaming and capture pic. Please make a video and create a html page and write mysql script and connect esp32cam with web.

Thanks! Very clear overview and explanation and nice test results. Out of interest, does ESPNOW work as an addition to wifi and bluetooth? Could all 3 protocols/radios be active at once? So for example, could I send control commands to an ESP32 via bluetooth, receive telemetry via wifi, and have it communicate with other ESP32's via ESPNOW all at the same time?

Hello Rui. I was watching some of your videos about ESP32 cam. very nice. What I need to do is create an intersection where I can delimit the image that will be saved on the sd card. for example the camera shows in real time in the browser and I indicate the exact location of the photo. would you know something that could help me?

when i tried practical communication of two esp boards using espnow i get only 15-20metre maximum range not a completely open area ,almost 2-3 walls were there between the two boards. I still dont understand how people claim to have range of above 200metres oin blogs and videos .Do you experience the same Santos?

Nice board, thank you for sharing. In order to save power if you use a battery as source, it would be nice to not have the onboard LED, can I simply omit that, ans it will still work as normal?

Hi Rui,, Thank You for this interesting data transfer concept with the TTGO board via SIM cellular networks . Appreciate it. Question What are your thoughts? To use one of these TTGO module for drone flying,,via GSM,rather than wifi 2.4 ghz (bypassing the wifi distance restriction) The drone broadcasts over wifi 2.4 ghz,,,so,, Could piggy backing one of these onto back of drone with small battery,, ( bridge wifi to GSM, in configs somehow) ,,wifi (TTGO) connects to drone wifi , with the drones SSID once TTGO is powered on,>>> TTGO sends data over GSM/cellular network to smart phone cellular connection,,,to wifi on phone so phone app could be used on phone same as wifi connected. The only thing cant figure out is how to make phone see this particular TTGO via GSM to gather data to the phones drone app ( to use the drones features via app such as follow me,, send video,,,photos erc) . . What am i missing? Thanks again

GREAT video and very easy to follow! Was the phone connected via a wifi or BT connection or was it USB? Would a cell phone be able to monitor more than one camera by opening multiple browser tabs/windows & could it record multiple inputs of multiple camera's? (even at reduced frame rate if possible/needed)?

Lets say if you have this sensor and a heart rate sensor attached . Will the same system work , as both of the sensors will produce data at their own rate . And what i think is that as the whole page is getting refreshed it might need all of the data at the same time from all the sensors

I have NODE MCU esp 32 wroom devkitv1 . It has no 5v output. (Only one 3.3v output) if I connect relay module eith external 5v power source and connect only the data pin with ESP 32 board, will my relay work? Will the ESP32 burn? I understand that the above question can be answered if I knew 1. Relay connected with just an external power source (no pins even data is connected with esp 32 board). What is the voltage reading of data pin of relay? [ I believe it should be 0, since this is just a triggerer] 2. Now I have connected relay module's data pin with ESP32's any data pin and relay's power is again given from external source. Will the ESP32 be able to trigger relay now? Please answer I am having hard times.

I think you can use an external power supply for the relays and just use the esp8266 to trigger them see 2:34 for the jumper but that could be specific to the relay board you have, the one I have does not have the external power supply jumper
