BrownBottle, What type of capture card are you using? By any chance is it a Kodicom 4400 style? I have recently started using one of those in a system and can't get any camera ports other than the ones "builtin" to the card itself to work. All external ones (port 4-5) give a sort of "...

What kind of performance gains would be expected with this on say Fedora Core 8? Has anyone tried this yet?

ext2 is dangerous. There is no journaling, so if there is a crash during a write, your filesystem is toast.

Will ZM 1.22.3 work in FC9 yet? What version of ZM is in the FC9 repo?

Anybody? I tried almost tripling the amount of shared mem on the weekend, to see if that was part of it. But even with more than 2 Gig of shared memory setup now, it still does the same thing. All ports other than 0-3. If I put the camera that is on port 4 (for example) on port 3, it works fine. It ...

The Kodicom 4400R card's inputs for cams 4-15 you need to connect each of the 8-pin sets to the 32-pins at the top of the card. I followed the documentation for this from the Wiki: http://www.linuxtv.org/v4lwiki/index.php/Kodicom_4400R but I'm getting odd results. I have tried with various inputs (r...

I have found picture quality on LED IR cams to be very poor, and range extremely limited. They may work in close proximity for your baby room monitoring (keep the camera no more than 6-10 feet from the crib)...but as any kind of outdoor camera, they are worthless until you are standing right in fron...

Well, an interesting turn of events in this one, for a follow-up... Turns out the camera I was using for testing ended up being defective. I tried it with another camera, and it works fine. Without the baluns. Resistance in the cable is less than 5 ohms at 100' under no load, which is comparable to ...

That should be fine for a computer. Disk size required will depend on many things, like frame rate, size of capture (640x480 vs. 320x200), length required to be kept, desire to keep archived events, ability to backup to tape or offsite, etc.etc. My person opinion on a camera would be something like ...

OK, I've done a fair amount of electrical work in my day, but this one just has me stumped. Why is it that I can run a 75-100' RCA cable and get a perfect picture, yet if I run 75' of Cat5e I get nada? I checked for shorts, and there is none...the cable is in perfect physically. Figuring it was some...

You don't need a video capture card to use IP cameras. The cameras go onto the LAN in your house/business. The CCTV capture card would be needed for analog cameras. Opinions on cameras will vary. I personally prefer the day/night style with either Sony or Sharp lenses on them, with either 0 or 0.1 l...

Hardware compression cards are not supported.

What type of system are you planning on trying to setup? Can you give us more details of what you're trying to do?

My reason for speed is writing, in particular. I want to be able to dump as many jpgs as I can onto the drive without losing frame rate. Not just on personal installs, but on customer installs. Anything to improve performance is always welcome. :) In my personal setup, I am running the following: Pe...

Can anybody suggest a filesystem that has faster read/write than ext3? Settomg noatime is a help slightly, but having higher performance would be nice. Ext3 isn't exactly known for its performance, even though with some tuning it does help (in fact, I think I even suggested this somewhere). But what...

If it works in low-res but goes green in high-res, maybe shared memory is the issue. This is a very common problem.

What errors are you seeing in /var/log/messages after it goes red?

The settings for bandwidth are for the assumption of viewing it from another machine. I'm with Lee...you're RAM is too low to be doing this. It's probably running slow because with X and the daemons running, trying to view it locally on Firefox is likely throwing your box into swap, and that will bo...
