This does not work for example on such a camera:

hostname=RC8221D46459
description=
defname=SCD46459
h264_resolution=640
mic_in=on
speaker_out=off
ptctrl=off
wlled=off
irled=on
serial=off
resolutions=1280960,640360,320180,16090
mac=00:0e:8f:d4:64:59
privacy_button=on
pir_sensor=on
wps_pin_code=39193216
ioctrl=on
company_name=Elisa
model_number=RC8221
wireless=on
fw_ver=V1.0.10R00
ip_addr=192.168.0.47
netmask=255.255.255.0
gateway=192.168.0.1
timezone=26
current_time=01/01/2010 03:50:50
http_port=80

rtsp_port=554

What to do? Are there any ideas or firmware to read and look for a password file there? Thank!
