ZoneMinder Forums

Hi,

I have a need. I would like to have zoneminder in a car recording a cycling event. I need it to store a couple of images and send them via a CDMA modem to a ftp server so it can show on a webpage (~ realtime images).

My problem is that zoneminder keeps images inside a event tarball and this tarball is huge. Its size depends (from 200k to 15.000k), i cannot figure why.

I would need to have a maximum of 1 image per second and send them each 5 minutes, so i could have realtime images on the server.

What type of configure should i do? Can this be done only through filters and web interface?

Thank you!

I'd see about writing a script to unpackage the tar and see if you can get more compresion out of the tar (ie tar.gz) that ZM uses or set up another zm box to try to capture from the other machine.
Or get an IP camera. I don't think you will get one FPS though GMRS.
Maybe 0.5 if your lucky or set the quality down.

The other option would be wireless set up a high gain directional on the receive side at one end of the course. This would only be good for a few miles at best though. You would need a licence to transmit any real power.

Hi.

This CDMA modem archives rates up to 1Mbit. The problem is that even with 1Mbit the archive speed of zoneminder makes a lote more than this can handle.

I would need zoneminder to send less frames in each tarball to the ftp server.
Isn't there a way to upload a frame every x minutes in the filters menu?

This isn't exactly ZMs normal mode of operations but you have two choices, both of which require a bit of simple scripting.

1) On your ftp server, just run a simple script that 'wget's a zms path to get a single image. Assuming you can route to the destination IP that is.

2) On the ZM box use zmu to dump the current image and then ftp it to your server, though I think you might find rsync or scp a bit easier to use from the command line.

Any help?
