Add a card with Philips SAA7134HL chipset
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 :-)
