BT878 Black and White Static, Help with Settings

[cpaplaczyk]

Hello,
I have researched this issue extensively and have yet to get anything better than a blue monitor or a fuzzy (black and white) non image screen. I do know that the camera is working since it was previously connected to a standard CCTV DVR. I am looking to move to ZM due to the limited ability of the DVR. Any help would greatly be appreciated.

Version: ZoneMinder v1.30.4
I installed ZM from, https://wiki.zoneminder.com/Ubuntu_Serv ... ell_script

Installed with the script labeled: Script for Ubuntu 18.04 - will install Apache, Mariadb, PHP and Zoneminder 1.30.4

Log Erros:
2018-05-13 14:43:11.052979 zms 1501 ERR Unable to validate swap image path, disabling buffered playback zm_monitor.cpp 4025
2018-05-13 14:43:10.983193 zms 1501 ERR Can't stat '/tmp/zm': No such file or directory zm_monitor.cpp 3493

The previous DVR system was made by Zosi so the cameras are by that company.

I have tried /dev/video0 through 3 and all possible channels. Channel 0 gives me a blue screen and channel 3 along with a few others give me fuzzy (black and white) non image screen.

I have tried setting the bttv.conf to options bttv gbuffers=16 card=77,77,77,77 as others have stated as well as the ZoneMinder wiki says. I still get a blue screen.

Output of: v4l-info /dev/video0

Any info would be greatly appreciated.


If your question concerns the API, make sure you have followed the documentation mentioned previously.

[bbunge]

The two "errors" you reported are not fatal and I have seen them on Ubuntu 18.04 before. They are the result of the way Bionic handles tmp files. You can change PATH_SWAP to /dev/shm

Check /dev/video* to see what values the system is assigning to your cameras. Blue screen errors are usually the result of incorrect resolution being used in Zoneminder. Also make sure the install script did the "adduser www-data video" If this user is not added local cameras will error out with bad permissions. There is also a chance that Ubuntu Bionic does not fully support the camera card.

Use 32 bit color, PAL-B, 320x240 to start

[cpaplaczyk]

As an update, I was able to get some sort of recognizable image. It looks like when I have the black and white fuzzy screen if I unplug and plug back in the camera sometimes I get a video that is split into three images. I can see that it is a video of the camera but it is clearly not visible enough for a usable image as it seems to be split into three images.

I can see with this the below settings:
Capture Method: Video for Linux Version 2
Channel: 2
Format: NTSC
Capture Palette: Auto
Multi Buffering: use Config Value
Captures Per frame: 2
Colorspace: 32 bit
Width:320
Height: 240

[cpaplaczyk]

I have posted screenshots below of the best settings I can get it at. It is very strange that sometimes when I unplug and plug the camera back in I get a clearer video, yet again it is fuzzy and it has three vertical sections of the image but I can determine that I am getting some sort of video feed through ZM.

As always any assistance is appreciated.

Last attachment.

[cpaplaczyk]

As you can seen from the screen shot below this is the best I can get. At times it shows this video and others it shows the video from above. It seems like it is a settings issue but I have tried almost all combinations.

If anyone has a suggestions I would be more than happy to test them out.

Thank you again in advance.
