I've tried the FireFly under Linux. It worked well. I don't remember if I tried it with PD/Gem but should be fine. I used Coriander http://damien.douxchamps.net/ieee1394/coriander/ to create a videoloopback device for V4L use. jim On Mon, 2009-05-11 at 23:02 -0700, Jaime Oliver wrote: > Hi, > >

Hi, I am about to buy one of these FireflyMV's. It's 350$ with shipping to california. Has anyone actually tried them? There is a new version with usb2.0, do any of you think it would be easier than 1394 to get these working under linux? best, J On Fri, Mar 6, 2009 at 10:06 AM, Martin Schied

Hello David, Thanx for all this informations using an analogue camera. It's good to know there is FireWire extensions, but it is very expensive (245 pound sterling !). If i understand, the system is like this : Analogue camera with BNC -> BNC baluns with power -> cat 5 cable -> composite ba

Hi Jack, I've done a fair bit of this sort of thing before. The most useful setup i've found is: 1) Analogue monochrome CCTV camera. (Preferably with around 700 horizontal lines or so, very low lux, and self syncing) I use these. http://www.allthings.com.au/Catalogue/CCS/monochrome%20l

hi Jack, it's about $200 for the "firefly mv". They somehow don't want their prices in public... I had a lower price in mind - maybe I mixed that up with the unibrain. I think for that application it's not necessary using higher frame rates. I tried simple movement detection and tracking in gem

mmh, I don't really know about lengths. I think there is a limit to how long your firewire cable should be.

Thanx for the reply. The models are too big for me. I need a smaller camera (something like a cube) because the installation must be discreet. Have you something else to suggest ? Chris : what do you think about Sony driver ? I can't use a PCI card because i will work with a macmini. ++ Jac

Latency is mostly affected by the device driver for any source. Even some of the professional capture boards have relatively high latency, but typically Firewire or USB based devices will have much higher processing time in the driver than an uncompressed PCIe card. On Thu, Mar 5, 2009 at 1:04 P

Sony Handycams are pretty good but you need to make sure that you can mount it on a tripod and charge it at the same time. I have had a lot of problems using some models of them, as the quality is excellent, they work with firewire but some models will only allow a firewire cable to be hook
