@stevencassidy (or whomever wants to input)

I've been trying to come up with a good IR light solution that will:
1. Bathe a large area with light
2. Keep the location of my cameras hidden

My experience shows me that unless I have that light source right up at the camera, lighting is minimally effective. I currently have both RPIs with NoIR's inside the house, against the glass in the corner of my windows.

Thanks in advance.

I have my camera inside the house against the window and the IR light mounted outside on the wall.

This is the lamp I purchased on-line for about £8

Thanks for posting that. I have 2 of those kids of lamps, and also a spotlight, but I've had little luck with it.

So, where is the location of the lighting relevant to the camera?

oops, should have read the first paragraph. Looks to be about 10-20 feet from the camera. I'll give that a shot next.

One question, is 1296x972 the highest resolution for full Field of View, or is more possible?
I tried 1944x1458 in the config file but it falls back to 1080p.

Yes I can. I'm going to need to try this again. The floodlight I used was in and about the same location, but much higher relative to the camera.

Thanks for sharing that.

Yes, 1296 x 972 is the maximum if you want the full field of view. To get that you have to read out the full 5 Mpix (2592 x 1944) sensor, but the system bandwidth doesn't allow doing that any faster than 15 fps (at best; there are other factors) so they use on-chip 2x2 binning to get full-sensor normal video rates, combining neighboring pixels on the sensor chip into one pixel before transmitting to the RPi, so resolution is 1/2 in each direction for 1/4 the total pixel count. Actually it's not that simple, they combine the closest neighboring pixels *of the same color* which due to the Bayer pattern filter array means the resolution goes down by more than 2x. So the best image quality mode is 1920x1080, and for a wider field of view it's better to use a cell-phone wide-angle adaptor lens (they are quite cheap, some under $10). (also, the Pi's H264 video compression system has an internal limit of 1920 pixels across.)

fwiw I actually had a different experience, or rather, I've not seen any requirement to have the light close to the camera. For example to capture licence plates at a distance I'm testing with a camera far away + telescopic lens (16mm) and the IR light close to the target. Bottom line what matters is that the frame where the lens is focused is well lit, I don't see why it would matter where the IR light is in ref to the camera.

also fwiw, after trying many different IR lights including building my own I've settled for the same ones that were mentioned in a previous post. The fact that they go on their own has the added bonus of allowing you to position the light away from the camera which:
1) doesn't attract people who see the glowing red to the camera
2) keeps insect away from the lens/camera

And in case people were wondering about removing the glowing red by using 910nm leds, I've tried many different configurations and I could not just get even close the amount of light that an 850 gives out (with a pi). Looking at the specs for the camera on the pi this is obvious as the sensor is more sensitive in the lower 8xx range than around 900.

hope that helps

Re: PiKrellCam: thumbs not showing up

Fri Sep 11, 2015 7:50 pm

@billw,

Today, I got the "502 Bad Gateway" when clicking on thumbs. They aren't showing up to the right of the video screen either.
I haven't changed any paths or anything else recently (except to bump up the stills resolution today), and I believe I'm up to date with the app.

What should I do? The log looks like it's creating them.

Thanks.

update: Turns out it's something with Safari, works fine in Firefox.

That does help. Being able to successfully position the light so as not to attract people to the camera (but perhaps the red IR light)

Thanks!

Thx for the information, i will stay at 1296x972 and the 2x2 binning. Iam using a s-mount fisheye lense (185 degrees horizontal) together with a non original camera board. It gives me a good picture quality.

Yesterday it was the first time I got problems with pikrellcam, before it was running for over one month rock stable.
Today I checked the thumbs page and found a movie with 0 MB, clicking on the thumb results in a "page cannot be displayed" browser message. Here are the log from the recorded file:

It looks fine (no error) but there isn´t a mp4 file in the videos folder, only the .h264 files ist there.
Could it be that the movie is to big (in filesize and runtime) for converting it? As you can see in the log it was ~700MB in filesize?
My media folder is located on a NAS and my Pi2 is connected via LAN, so the coverting to mp4 is done on the NAS directly.

Maybe a file split function for long movies could be helpful, just a guess.

If there's a h264 file and no mp4, it means the MP4Box command had an error exit. If you
still have the h264, can you try running the equivalent MP4Box command (witout the -quiet and
2> /dev/null) from a terminal so you can see any error output?
Maybe it would give a clue about what would be needed to do.

So the command to run would be:

Code: Select all

MP4Box -fps 24 -add /mnt/cam/media/videos/motion_2015-09-17_15.36.16_448.mp4.h264 /mnt/cam/media/videos/motion_2015-09-17_15.36.16_448.mp4

Maybe MP4Box was using a tmp file on your Pi and if that was in /tmp then there would
not be enough space. A little bit more info from MP4Box about the file it was trying to
write would have been nice. Try a couple of things: first run again but add a "-v" flag
to MP4Box to try to get more information. Second run again but this time specify
a tmp directory on your nas where you know you have enough space. So for this
add "-tmp /mnt/cam/media/videos" to the MP4Box command. Oh, and for this, I'm curious
to know how long that MP4Box command runs - if it runs without error that is.

If it turns out its a space issue in /tmp on the Pi, I would rather have the MP4Box runs
use a -tmp option than go down the road of splitting up the video recordings.

Using the -tmp parameter of mp4box pointing to a different directory does the trick.
My /tmp is in Ram (tmpfs) and 70MB in size and therefore to small.

I now changed the parameter RAMTMP from yes to no in /etc/default/tmpfs so that the Pi is not using /tmp in RAM anymore.
But it would be fine (if it is possible) to have the option in pikrellcam to configure the -tmp parameter of mp4box.

I just measured the two diffrent convertions with a testvideo.
30 Minutes video with a filesize of ~1GByte
converting with standard-temp path of raspbian (/tmp on SD-Card)

Code: Select all

MP4Box -fps 24 -add /mnt/cam/media/videos/test.mp4.h264 /mnt/cam/media/videos/test.mp4
takes 3 minutes 25 seconds

converting with MP4Box -tmp parameter set to my NAS filer

Code: Select all

 MP4Box -fps 24 -add /mnt/cam/media/videos/test.mp4.h264 /mnt/cam/media/videos/test.mp4 -tmp /mnt/cam/media/videos
takes 8 minutes 15 seconds

Bill,
Thanks again for your hard work with this excellent software. I know I requested the full image video be implemented, however I was unaware of the binning used on the camera board. So in the end I'm not sure if the result would be worth the time. I really would like to have the highest resolution video possible which leads to my next request. You have a settings limit on the video bit rate. In my testing, that extra information is the difference between getting a license plate number or not getting it. Can you allow the software to access the full bit rate allowed by the hardware? On kind of the same thought, is it possible to trigger full still images on motion detection? Another user has asked me if that was possible, and I did not see that information anywhere. I would try to assist on such projects, however my skills are limited to digital forensics, not coding. Never was really good at writing more than simple algorithms. Again, thanks for your hard work. -Mike

I've been down the same road you're on, I think. Video mode is really what you want for taking pictures of cars in motion. The 1920x1080 video mode has significantly better resolution than the 2x2 binning "full frame" approach in my experiments. With the various approaches I've used there is at least about 0.6 seconds between asking for a full-res still frame and capturing it due to internal mode-switching overhead, by which time usually what you're looking for is gone. Unless you have the luxury of camera placement very nearly on-axis to the motion, in which case maybe you can get away with that lag.

On the other hand, billw has done some great stuff already with PiKrellCam and maybe he can do better than the various still-capture approaches I've seen so far; I certainly wouldn't want to stop him from trying!

My memory is a little vague on why I set that max bitrate, maybe I wasn't sure what the max
actually was at the time. Anyway, I will increase it and in the meantime if you need a higher rate
immediately you can edit ~/.pikrellcam/pikrellcam.conf and set it there. It's just the OSD that
needs the max limit fixed.

In the scripts/preview-save script you can enable taking a still (and make sure the
on_motion_preview_save command is enabled in pikrellcam.conf. You can also set up your
own on_motion_begin script to take a still.
But if you mean something different like you want stills instead of video, right now you will always
get a video and there's no configuration for a sequence of stills beyond what you might be
able to set up in the on_motion_begin and on_motion_end scripts. Is that what you mean - stills
instead of video? And if so, a single still or a sequence?

A while ago a put up a fix for a web page bug that has hit me a couple of times and I
finally realized what was happening:
  • 1) On the videos page do a "Delete Day" of the current day.
    2) Stay on the videos page until some new motion videos are recorded.
    3) Hit the browser reload and the new motion videos will also be deleted before you can see them.
Anyway, it should be fixed now.
