Same hardware as Bell (more detailed hardware configuration there)

Running the following services:

  • Non-vital services that used to run on Boole.
  • Local LDAP services replicated from Turing.
  • ZoneMinder CCTV recording from legacy analogue cameras (b/w & colour) - possibly feeding into Bruce (the new ZoneMinder server)


Denning has a full height 8-port PCI video capture card installed to digitise the analogue cameras.

The card is 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 a BT878 8-chip 8-input full height PCI card similar to the 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, however, we may have to drop the resolution to 360 x 288 - realistically this may never happen as we have been opting to install IP cameras in the space - superior images and no complicated capture cards for image acquisition.


Currently has only a single mechanical hard drive so vulnerable to data loss. There is space for a second hard drive if we want to mirror the drive.
