Proprietary SMICT (Super Motion Image Compression Technology) with 1400:1 video compression provides for the smallest compressed file sizes for high resolution image reproduction, and thus providing the user with "all-hard disk" recording featuring the longest recording times and smallest bandwidth with best frame rates, allowing for remote connectivity over LAN and even PSTN when compared to other technologies using MPEG,JPEG,Wavelet, H.242/243 etc.

• A recorder may be used as a stand-alone system, or be connected to a network to cover the installation of hundreds of cameras, allowing up to 32 users to simultaneously view both live and pr eviously recorded video over a LAN or WAN from either multiple software equipped operator review stations running Digital VDO software, or the recorders themselves looking down at other recorders, and in most cases without the use of a dedicated server.

• All hard disk recording that may record video for months onto reliable lkegami Genius designed hard disk arrays. Unlike other systems, no tapes need to be managed or maintained weekly as with other systems using AIT/DAT or -DIV tape storage mediums and combination mechanically driven tape jukeboxes.

• No degradation over time of recorded data as well as immediate access to pre-recorded video without human intervention.

• Password protected, multi-level: Supervisor, Administrator, Operator, Remote User. Built-in Video.

• Authentication forcourt admissibility purposes.

• Unparalleled zoom video enhancement capabilities.

• Easy to use "make a clip", "take a snapshot" operator review mode.

• May control PTZ devices either locally or remotely via built-in RS-232 port as well as connect up to 32, 8 Input / Output I/O modules providing a total of 256 alarm and control relay points.

• Built-in 16xRW-CD for archiving of close to a days' video from 16 cameras at 2.5fps.

• Built-in Glide-point mouse for system set-up and local system operation.

• NTSC, PAL compatible. Variable frame rates per 4 inputs per video card.

• Features "field upgradeable" addition of 2 extra removable hard drives for added storage capability.
  *Need to change wire configuration.

• Built-in USB port for connection to storage devices.

• Built-in Video Motion detector for alarm marking, increasing recorded frame rate, as well as r emote signal of alarm conditions.

• May send alarm messages to a cell phone or other dial up device using pre-recorded voice prompts.

• Features 1 channel of audio recording, audible hi-temp and fan fail alarm.

• Front mounted, accessible, washable air filter.

• The system may be used as a stand-alone recording device with a VGA monitor and keyboard connected to the recorder, or, be connected to either a 10 Base T or 100 Base T Network, allowing up to 32 remote operator review stations to simultaneously communicate with a recorder, offering both live view, playback as well as remote file transfer . In addition to this feature and unlike other systems, the Digital VDO recorder itself may be set up as a client, to view video from other remotely or LAN connected Digital VDO recorders without the required use of a dedicated server or dedicated review station/PC as with other competitive technologies.

• The system with all 4, 4-channel Video capture cards installed, and all 16 cameras connected to the system will record Video from these 16 cameras at between 2.5 and 3 fps at 220 Horizontal TV lines at 320 x 240 tile size format onto a single factory installed 75 GB drive for between 30 and 60 days, more if ther e is less activity within the field of view of the cameras. Traditionally, other systems using other standard compression technologies would r ecord Video from the same number of cameras at a lesser frame refresh rate as well as lower resolution for only about 48 hours instead of one month as with Digital VDO.

• File sizes are dynamically changing based on background and foreground high fr equency algorithmic calculations, providing a changing Video bandwidth that also makes PSTN telephone line transmission a reality without sacrificing eitheron resolution or frame refresh rates. Typically using a PSTN connection with a 56KB modem, 4 cameras may be viewed at 2 fps each in a quad mode down a traditional phone line with a 56KB modem at each end with 56 KB data transfer rate available.

• The system may be accessed once started by entering a valid password. Once entered, system parameters may be adjusted to account for lesser number of cameras connected to each Video capture card and thus increasing frame refresh rates on a percard basis, changes to r esolution and Video sensitivity, assignment of passwords, camera and system descriptions, PTZ control, alarm functions, setting up 4 Video motion detection zones per camera for alarm transmission/alarm marking/frame rate increase, etc.

• Once the Video threshold of the defaulted 500 MB of spare overhead space in the standard 75 GB hard drive is achieved, the system will rewrite the oldest stored Video with the latest curr ent hour. To satisfy needs in other countries whereby a maximum of 31 days Video archival is allowed by local regulation, the user may change this Video recording threshold accordingly , but not below 500MB.

• It is suggested that all the Video be stored onto the recorders hard drive, or additional hard drives, for the period that is required by the client, example, 2 month, 4months etc., and that files are transferr ed for scenes of interest or alarm onto the recorder's RW-CD.
