### PSRAM ### PSRAM / Buffers / JPeg quality
Some esp32cam modules have additional ram on the board. This allows to use this ram as frame buffer. Some esp32cam modules have additional ram on the board. This allows to use this ram as frame buffer.
Detecting and using this special RAM is handled automatically.
The availability of PSRAM can be seen in the HTML status overview. The availability of PSRAM can be seen in the HTML status overview.
### Camera modules Not all the boards areq equipped with PSRAM:
| Board | PSRAM |
|--- |--- |
| ESP32CAM | Yes |
| ESP32CAM (USB-C) | No |
| AI THINKER | Yes |
| TTGO T-CAM | No |
| M5 STACK| | No |
| WROVER KIT | Yes |
Depending on the image resolution, framerate and quality, the PSRAM must be enabled and/or the number of frame buffers increased to keep up with the data generated by the sensor.
There are (a lot of?) boards around with faulty PSRAM. If the camera fails to initialize, this might be a reason.
In this case disable the use of PSRAM in the configuration and do not use camera modes that require PSRAM,
For the setting JPeg quality, a lower number means higher quality.
Be aware that a very high quality (low number) can cause the ESP32 cam to crash or return no image.
The default settings are:
- No PSRAM
- SVGA (800x600)
- 1 frame buffer
- JPeg quality 12
- With PSRAM
- UXGA (1600x1200)
- 2 frame buffers
- jpeg quality 10
### Camera module
Be careful when connecting the camera module. Be careful when connecting the camera module.
Make sure it is connected the right way around (Camera pointing away from the board) and the ribbon cable inserted to the end before locking it. Make sure it is connected the right way around (Camera pointing away from the board) and the ribbon cable inserted to the end before locking it.
