==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 :-)
