Has anyone tried the Logitech HD Pro Webcam C910 USB camera with zone minder? Does anyone know whether it might be compatible?
Thanks!

Re: Logitech HD Pro Webcam C910
Hello,
I was able to get working system with 6 C910 cameras. But it is quite hard. At first, driver for C910 allocate whole USB controller, so you can not connect more than one camera per controller, so I have added 4 additional USB controllers to computer. I have reported this problem to uvc driver developers, but I'm not sure, if this problem is solved. For connecting C910 camera I used mjpeg streamer, because using YUYV format is not good for frame rate. Due memory allocation for mjpeg streamer I have to increase memory for kernel using this parameter in grub configuration "vmalloc=256M", you have to increase memory for zoneminder too (my settings is kernel.shmall = 262144, kernel.shmmax = 1073741824). At lease I have to disable motion detection because with enabled motion detection I get load over 5 with AMD PhenomII X6 1075T processor. With 2 TB HDD I'm able to store about 7 days back with 4 pictures per second from 7 cameras. Last camera is connected to another computer and solution is same as for local cameras connected to computer with Zoneminder. As distribution I use openSuSE 11.4 32bit with Zoneminder build from Monex repository, I didn't try to compile Zoneminder by my self.
