In the UK we've had some amazingly cold weather for the past three weeks or so. Rarely going above freezing, I've recorded -15c personally and had several days concurrently of around -10c. As well as the chaos this is causing the plumbing on our three stableyards, I've also had some issues with the ...

Pretty much all that is doable, with one exception. Sound. ZM doesn't do sound. *However* - most cameras allow you to view them directly, and if using mpeg4 as a stream, VLC will certainly allow two concurrent streams and more. (In a web browser, many require activex which is IE only, and IE doesn't...

I'm not experienced with analogue stuff, but that looks like a four channel Bt878 card, which your distro appears to have correctly identified. Have you tried simply plugging in a camera and trying to view /dev/video0 through /dev/video3 with video software? I think there's a fair chance it'll just ...

Note: It's entirely possible I've misunderstood this completely and am about to make an arse of myself. If that's so, please let me down gently... Do you mean MPEG4 instead of RTSP? RTSP is an alternative to HTTP for transport but afaik, still delivers an MPEG4 instead of MJPEG or JPG. You can get m...

I got one of these; http://www.dealextreme.com/details.dx/sku.41929 No branding anywhere. $57 us (About £38 uk) Features: IR LED's. DDNS. (Untested) Um, that's it. Usual long delivery (5 weeks, but it's xmas, usually 3). Plug is US, but it's 5vdc and I used a poe splitter. Also some axis and y-cam ...

This might work; Create two monitors for each camera. The first one is normal modect and doesn't send anything anywhere. This is the one you check normally. The second you setup to send to ftp/phone whatever, but limit the entries under the camera's 'buffer' section. Limit pre and post to 1 or 2 fra...

It's best for security to put the server elsewhere, so if it gets torched or trashed you have some evidence. However, two things to consider which often prevent this from working well. 1. Reliability of remote networks. Not as good as local wired networks. 2. Bandwidth. This will restrict the qualit...

The recording side of what you want is fine. The difficult bit, as far as I can see, is the "fetch xx at yy and put in zz". That certainly isn't supported out of the box, but you may be able to do something clever with scripting and the mysql database directly to locate files from a specif...

Just a thought, keeping it simple; Avoid zoneminder entirely. Add a PIR sensor (or old PIR light with the light bit removed) that activates a siren or lights as well. If lights, that will trigger an event, so you have a record of what goes on. Of course, will need some careful aiming to ensure cats ...

Too much for zm? No - but it might be too much for your server...

Depends hugely on fps, image size, colour or B&W etc.

Don't know what you mean by swf, but the most common reason for a feed working in low res but not high is that the shared memory is not enough.

See the wiki for shmall / shmmax settings,

As far as I know not possible through zoneminder itself.

However;

You could write a script that issues a few mysql commands to empty the database of events. Zmaudit would then automatically remove the orphaned image files.

Never heard of anything like this, but here's a couple of suggestions. Upgrade the firmware on the camera to the latest if not already. Change the existing monitor to "None" and create a *new* monitor using exactly the settings (including buffers) that you have on your working Axis mjpeg m...

It's possible, more movement.

If you want to test your theory, run munin and graph things like system load. You'll see if it changes significantly.

Is there any web interface? How are you intended to view the image with this camera - can you get a jpg or mjpeg url from that interface?
