Not working to do snapshot or recording using ESP32 CAM

ESPHome
1

Hello All. I am here to ask you the function for snapshot or recording using the ESPcam.

I bought the ESpcam mentioned in the link below.

And I think that it is gorgeous to use the camera with a very low price. But I got to know that this Camera dosenot support the snapshot or recording function.

i got the error mesage like below when i tried to do it by following the instruction from the official homeassistant.io site. ( https://www.home-assistant.io/components/stream )

–> Error Message: camera.espcam does not support record service

The reason why i bought this is for the Surveilance by automation and I need to record or get a snapshot to send it to me by telegram or any other ones.

Therefore, Is there anyone who has a solution about this?

THank you in advance.

I had the same concern and wrote a script to make recordings using ffmpeg.
Running the following in a shell session will make a 1 minute recording:

  ffmpeg -i http://ip_of_ha_instance:8123/api/camera_proxy_stream/camera.my_camera?token=YOUR_CAM_TOKEN -t 1 -vcodec copy  /home/videos/recording.mp4

Possibly, you could integrate this with a python script in HA (I am not using the HA frontend and I use Appdaemon for automations). Regarding snapshots, this works fine for me using the built-in snapshot service so you might be doing something wrong when calling the service.

Unfortunately, The token is changed from time to time. Therefore, I couldnot input the correct token in the script you mentioned above. How can i input the fixed token?

In addition, I also got this error message, when I input the script you mentioned above.

–> http://192.168.0.xx:8123/api/camera_proxy_stream/camera.my_camera?token=xxxxxxxxxxxxxxxxxxxxxxxxxx invalid data found when processing input

Can you please let us have your additional advice? Thank you in advance.

Did you replace camera.my_camera with the actual name of your camera entity? I am travelling today but I can upload my full python script later that also handles the token that changes every 5 minutes.

sure. I put my own camera name and sorry to make you confused.

It seems that the changed Token is one of the rootcause for no working of the recording. As i checked the token and inputted the your command included with token ASAP before change or I also inputted all command I can do ASAP. But it showed some error message i mentioned above.

Therefore, I think that there is another reason that the recording is not working. But I will try anything i can.

Thank you for your kindness and sorry to disturb your trip. Please let me have your python script later, if available. I appreciate it.

@tjntomas i was wondering if you can post your python script on the forum im also wondering how you did this. :slight_smile:

Sure, I 'll take some time to post the script shortly.

You can get the current access token or most of the required url using templates… assuming the camera’s entity id is camera.esp32_camera

This works for other cameras too; not just esp32 cams :slight_smile:

access token only:

{{ state_attr('camera.esp32_camera','access_token') }}

most of the URL for a single image:

{{ state_attr('camera.esp32_camera','entity_picture') }}

Single image:

https://YOUR_DDNS_URL{{ state_attr('camera.esp32_camera','entity_picture') }}

Video stream:

https://YOUR_DDNS_URL/api/camera_proxy_stream/camera.esp32_camera?token={{ state_attr('camera.esp32_camera','access_token') }}

Your script is trying to make a directory that already exists.

I am getting this same error. The token and camera name is correct. But was there a solution to overcome this error?
