1920x1080 Anyone done it yet?

I have a possible application where the customer wants HD video, to see
some very fine stuff, has anyone used a 1920x1080 cam with ZM? Of course
I am assuming that is going to take a major adjustment of SHMMAX and need
plenty of memory, and machine speed. It will use gigabit IP with gigabit
switches and NIC cards.

If anyone has already jumped into this would like to know what they have
experienced? The client was in a casino, he was shown the security video
off of the card tables, it was 1080p for pretty obvious reasons they want to
SEE everything, the client wants to do something similar, but wants it done
with ZM if possible.

I have done MJPEG 1600x1200@8fps on AMD X2 4400+, 2 GB RAM. I could only do one camera though, so I settled with 800x600 with 2 cameras. It's doable but the server has to be really really fast CPU-wise and you have to dedicate separate network just for the CCTV.

Hmm yours is 1M920 pixels and mine is 2M07 pixels so not that great a delta, it looks like I just need to use a lot of processor to do it, perhaps a
quad, going as fast as the customer will pay for it??

Will have to get a cam and start testing it out, that is going to be a expensive
test but if I want to snag this I have got to have a better idea of how it is
going to work.

I've done 960x720 with a Logitech Quickcam Pro 9000 and the images were very clear. If you want to sacrifice performance you can use YUV mode instead of MJPEG (mjpeg-streamer) which will allow you to reduce image compression/quality higher than 80%

What settings did you use for the quickcam pro 9000?
Newegg has refurbs on sale for $48, a good deal for a 1600x1200 cam IMO.

Just for the record, I can use a Logitech Quickcam Pro 9000 (version2) at 1600x1200 at 5fps, using zm 1.24.2 on Ubuntu Server 9.04, with no problems. (P4 2.8HT with 2Gb RAM)

Source:
Device Path: /dev/video0
Capture Method: Video for Linux 2
Device Channel: 0

Capture Palette: YUYV

Remember that some Logitech 9000 cameras, there are 4 versions, are buggy under Linux .

I have an axis 223M set on 1600x900, pulling consistently 4-5FPS on a core 2 quad 2.3ghz, 8 gigs ram, 13tb drive space, but the camera's running through 3 100bt switches (and probably a longer cable run than should even work for part of the stretch) before it gets to the server, and the server's also hosting 28 other cameras (roughly 2/3 640x480, 1/3 1280x1024). Ubuntu 9.10, ZM 1.24.2, mmx jpeg libs.

And the gui's running, along with a minimally used wiki.

Quad core cpus are so cheap I would definately go that way if you want to do multiple cams. Combined with intel ipp (see recent posts) or some other optimization libs (plus limited zone areas if possible) you oculd pull off multiple cams at that resolution. Make sure to do a decent hd raid setup to help too.

Depending on how many of these cameras he's going to want, and how many FPS, RAID is a must. And core 2 quads are wonderful chips, my machine (prior to adding the RAID and bumping the ram to 8gb) cost me around $700 initially (2 years ago), refurbed HP Pavilion media center, so as a bonus, it came with a hauppage tv tuner/video input card in case you throw an analog camera into the mix. ZM has a variety of processes for each camera that are constantly running, in addition to your operating system, and any viewing sessions going on, so the more cores the better.

On the other hand, depending on the application, you might be able to get by with an analog auto-tracking PTZ camera with a nice optical zoom. Bluecherry carries a nice 36x optical ptz http://store.bluecherry.net/PTZ_AT_Auto ... at-36x.htm which if you're only tracking one person, vehicle, etc., you can get amazing close-ups without requiring the higher resolution. Obviously if you're trying to cover a room full of people, this wouldn't be a good option, but if you're following 1 person or vehicle, the 480 tv lines of resolution are plenty thanks to the optical zoom. I've gotten license plates and great facial shots from 100 feet away.
