Re: PiKrellCam: motion vector detect + OSD web interface

PKC-alarm I have been using pkc-alarm and motion-send-alarm to trigger a script to start recording in other pikrellcameras. But I get several short clips from the trigger time and then a long one. Any idea what is happening? I thought pkc-alarm was filtering resends but maybe not. Would the script ...

Re: Reducing noise when recording with Pi

Yes, I can go all out on a really good usb soundcard (100+euro) and a really good microphone (50+euro) or a yeti usb mic (120+euro) downside of this is that it costs a lot of money and takes up a lot of space plus may need an additional PSU. My current setup cost about 10 Euro for mic (electrets + c...

Re: PiKrellCam: motion vector detect + OSD web interface

I have another issue but its camera/hardware I think. Randomly, the v2 camera on my Pi 4 will just stop working and only work again after a reboot or shutdown/on again. It is connected using a 1 metre ribbon cable so it may be that. I was having a similar issue with the pihut zero cam (+converter+s...

Re: PiKrellCam: motion vector detect + OSD web interface

FWIW: I've had good luck running PiKrellCam with v1 and v2 cameras on Pi3 and earlier devices, for several years now. With the HQ camera and Pi4, I have to reduce frame rate to 20 fps for the preview to be stable, and I am also seeing the preview GUI freeze after running for an hour or so (although...

Re: Reducing noise when recording with Pi

@scruss: The Pi0 with powerbank was actually a crappy USB soundcard. It looked the same in different computers and with different powersources. I just used the "on powerbank" picture as an example of what noise from a crappy USB soundcard can look like. My aim is to get all noise down to about -60 t...

Reducing noise when recording with Pi

I am sure everyone trying to record sound with a Raspberry Pi has experienced a lot of issues with noise pollution. Although there is any number threads on various forum adressing this I have yet to find any conclusive answers. I posted this as a question on stackexchange https://raspberrypi.stackex...

Thanks Bill! I have not quite got it to work but I will continue experimenting until I get it right.

Is it when no more motion is ...

Re: PiKrellCam: motion vector detect + OSD web interface

Is there any way to "artificially" trigger a motion event after a motion video has reached its time limit? I set the video time limit to 5-6 minutes because the Pi0 i am using cannot handle the conversion of too big files. However, there are times that I would like pikrellcam to start a motion even...

I have recently tried a NoIR camera in my new appartment and started getting this strange interference, see photo below. I comes and goes randomly but happens mostly at night in a dark room.

Re: PiKrellCam: motion vector detect + OSD web interface

@billw - Is pikrellcam using mostly GPU or CPU for the motiondetection and video conversion? Perhaps I am setting the memory split to high (256mb on Pi0) I remember a block diagram of the program that I saw but I cannot find it anymore, though I think a lot of processing went on in the GPU? I am al...

@QSKONE MotioneyeOS is an standalone OS so you can use all the normal terminal commands and files you find the normal Raspbian. Ask CCrisan at the motioneyeOS hub.
