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 [https://wiki.zoneminder.com/Kodicom_8800 Kodicom 8800]

Each input is configured with:

* 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.
