Denning

Runs the non-vital services that used to run on Boole. Might get used for other stuff as well. Same hardware as Boole

Runs the local LDAP server. The LDAP db is replicated from Turing.

Runs zone minder, see below.

Zoneminder/cctv

Has an 8 port video capture card in it. It's currently connected to the 3 yard cameras and the rear lobby camera. The other 4 inputs are disabled until we put more cameras up.

The card is one of these (or a clone):

• http://www.zoneminder.com/wiki/index.php/File:Karta.jpg
• http://www.zoneminder.com/wiki/index.php/Kodicom_8800

The modprobe.d settings I'm using are:

options i2c-algo-bit bit_test=1 options tuner debug=1 options bttv gbuffers=16 card=102,102,102,102,102,102,102,102 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 audiodev=-1,-1,-1,-1,-1,-1,-1,-1 v4l2=1 bttv_verbose=1 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1

Each input is configured with:

• fps: 10
• alarm fps: 25
• palette: BGR24
• resolution: 640 x 480

This might just about work with all 8 inputs, we may have to drop the resolution to 360 x 288

The old card.

Issues

Has only a single mechanical harddrive so vulnerable to data loss.
