Chapter 1 Product Introduction
1.1 Summary
The Alien Pro series Network Digital video Recorders are excellent digital
surveillance products. They adopt an embedded MCU (Microprocessor Control Unit)
and an embedded Real-Time Operating System (RTOS). They combine the most
advanced technology in the Information Industry such as video and audio
encoding/decoding, hard disk recording and TCP/IP transmission. The firmware is
burnt onto a flash memory, which makes it more stable and reliable than software
programs that run from a standard disk drive.
The Alien Pro series combine features of both Digital Video Recorder (DVR) and
Digital Video Server (DVS). They are widely used as stand-alone units or part of a
powerful surveillance system.
