ZoneMinder Forums

• watch both monitors from the android in the monitor view
• detection, capturing, review, etc, as expected for the first 5 monitors listed - all H264 streams
• link trigger for the ip-cam image monitor
• capturing of jpegs in files like
  /var/cache/zoneminder/events/9/2020-01-05/1537/00005-capture.jpg
  I can see them there with e.g. sxiv via ssh X-forward
• browsing of stills, thumbnail generation in the zm web gui
• some frozen, broken video streams from the events (usual first frame of event, no black or empty screen)

• at 0.1 fps , I have to generate events that are at least 10 s long before the link is triggered and an image is recorded
  shorter events at the master are ignored at the linked monitor
  severity: high
• the jpg is read at the 0.1 fps all the time, even without alarm condition
  this way, in my test setup, this only monitor is using half of the network capacity, albeit only 1,2 % CPU for the zmc
  severity: critical - well, maybe Gbit networking may help
• the generation of web stream from the jpegs is broken,
  monitor view window keeps reloading als the time
  I get errors in the log regarding sockets going away
  zms pid counting up all the time I keep the monitor open and autoreloading
  may be it is this issue viewtopic.php?t=20902
  I'll check and report
  severity: nasty, but I think solvable or at least workaround possible
  so I'll postpone that for the moment
• when I try add pre/post event images, the link trigger seems to be broken
  severity: medium - would be low if link trigger did occur immediately
• I tried to switch frame rate in alarm condition
  e.g "Alarm Maximum FPS = 0.2" and "Maximum FPS = 0.05",
  but did not see a consistent reproducible effect
• when I set Monitor function to anything else than Nodect, the link trigger seems to be broken
  severity: low - it's more a matter of (missing) documentation
  so I stop complaining, since I don't want to get the job assigned

Changing the location for images and events
-------------------------------------------
Zoneminder, in its upstream form, stores data in /usr/share/zoneminder/. This
package modifies that by changing /usr/share/zoneminder/images and
/usr/share/zoneminder/events to symlinks to directories under
/var/cache/zoneminder.
