Denning
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)
Zoneminder/CCTV
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.
Issues
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.
