The Ademco RapidEye Multi is a small CCTV DVR, serving the same purpose as the Pelco. As it turns out, this hardware is quite different from Pelco's. The Ademco uses a Pentium-I desktop, wrapped with a custom housing and interface boards.

Warranty Void

The unit is also running Wind River VxWorks. Since we all know a Pentium cannot simultaneously compress 8 different video streams, this card contains the extra horsepower. It also has a small wire running to the motherboard's reset line.
PCI Video I/O Card

The unit also has a modem and two serial ports. If you attach a cable to the second port, you can interrupt the boot sequence to change settings like the IP address. Use 8-N-1, 9600 baud. You'll need to press enter quickly to block the boot-up sequence. Here's an example capture:

I also imaged the disk. The disk is split into two partitions. The first is a 2GB FAT containing VxWorks. The second is a partition listed as 'free space', but actually holds the video data. Here's the file list:
