Videocards with Philips saa7134 chipset

Add a card with Philips SAA7134HL chipset

Create or edit file /etc/modprobe.d/options.conf

alias char-major-81 videodev
alias char-major-81-0 saa7134
options saa7134 card=33,33,33,33

Then execute command:

modprobe saa7134

Some users have reported that this method can resolve situations where only gray scanlines where captured from the camera.

If above doesn't work, you can try

modprobe saa7134 card=60,60,60,60
or
edit your modprobe.conf to include
options saa7134 card=60,60,60,60

All Philips saa7134/7135(HL) cards should be automatically registered by kernel since kernel 2.6.2x.xx, but i am not sure so, please verify!

NOTE

Do not forget to to increase "shared memory" at the end of /etc/sysctl.conf with
kernel.shmall = 134217728
kernel.shmmax = 134217728

cause your card supports 640x480 pixel with 24 bit depth and thats more than 112Mbyte ;-)

NOTE

You have to define following things at source of camera:
1st capture method = v4l2
2nd device channel 3
3rd device format PAL (and not NTSC -> causes some vertical flips)
And, last but not least... do not worry if you got no signal after changing resolution -> just restart zoneminder after changing parameters!!!!
max. resolution seems to be 720x576 ... also 320x240 and 640x480 seems to work... please verify :-)
