Beaglebone Black Industrial
Logitech C545 webcam
'''Steps:'''
Installed Debian Jessie via a netinstall from [http://elinux.org/BeagleBoardDebian Elinux.org BeagleBoardDebian]. Used serial port. Migrated to Devuan. Installed Zoneminder using jessie-backports according to [http://zoneminder.readthedocs.io/en/stable/installationguide/index.html official install guide].
Industrial BBB was chosen, in the hopes of using it as a dashcam under winter conditions.
Camera works plugged into USB. No external power needed.
Logitech camera works under the following settings
'''Zoneminder settings:'''
* Source: Local
* Maximum FPS: 3
* Device Path: /dev/video0
* Capture Method: Video for Linux 2
* Device Format: PAL
* Capture Palette: *MJPEG
* Capture Width (pixels): 960
* Capture Height (pixels): 720
Total load with camera, gets about 960x720 3FPS, with .7 load on the server, in monitor mode. Making this a potential external ZM server.
YUYV works with resolution of 320x240, but no higher. MJPG is able to get 320x240, 640x480, and 960x720. I put the wrong resolution in during MJPEG mode, but the ZM logs happily told me that the 'correct' resolution available was 960x720, so I used that, and all worked.
This being an SBC, there is a additional interfaces, expansions (I2C, GPIO) to use in addition to the camera itself. Sensors can be added easily.
'''Notes:'''
* I ran into problems using this BBB with a long (>25 ft) ethernet cable. Network functions were slow, or failing. This could be a problem if you were to use these as substitutes for cameras. It may have been my particular model (BBB Element14 industrial). A shorter cable resolved all issues.
