Raspberry Pi Forums

Good day fellas, have a problem with Raspberry Pi camera which I got from Aliexpress, seller cant give full datasheet, manufacturer too. I just want to control IR filter on it, to turn on/off night mode, by soft, not thru light sensor, without rebooting system. Camera based on OV5647 stone. Please help me!

Provide a link to the Aliexpress page, otherwise we're having to guess.

The most common OV5647 with controllable IR cut filter is the Waveshare one - https://www.waveshare.com/rpi-ir-cut-camera.htm
Read the wiki for controlling the IR cut filter.

You can generally control the camera LED line via software, but it is not connected to the same GPIO on all variants of Pi, and on the Pi4 it is actually absent due to not being a requirement on the currently supported camera module (IMX219).

Here is the Link for camera. So its impossible to turn on/off night mode without rebooting system?

So you set normal / NoIR mode by (un)setting disable_camera_led...

You can try if 'picamera' can do the same: https://picamera.readthedocs.io/en/rele ... ng-the-led
Or by using GPIO32 (GPIO5 on older Pi models): https://www.raspberrypi-spy.co.uk/2013/ ... ra-module/
Interestingly viewtopic.php?t=213170#p1314269 mentions GPIO8

No idea if these methods (still) work.

If you want to know what GPIO the LED is connected to, the official source is https://github.com/raspberrypi/firmware ... t-blob.dts and look for the CAMERA_0_LED property for your particular board variant.
If it is listed as external, then it is on the GPIO expander. Internal is the same Broadcom pin numbering as used by most userland GPIO libraries.
It's never been on GPIO8.

Yes, PiCamera has a slightly icky mechanism to set the LED from your app. See https://picamera.readthedocs.io/en/rele ... Camera.led Please note the provisos.

Thanks a lot guys, I hope this will help, appreciate your help.

Product description from your link says no, but you should be able to change the camera led GPIO with eg. pigpio pigs command as well.
I have a similar camera at home, that uses a photo resistor to change between day and night mode.
