. Typically, 2 to

7 minutes of single video segments can be exported to a single

1.44 MB floppy disk.

Video exported to a CD includes all 16 video channels and one

audio channel recorded, with alarm information to the hard drive

during the segment exported. The CD is recorded in an

ISO9660 format and can be played back using an AurorAcorD

unit. Depending on activity, typical segments, ranging from 10

to 12 minutes, can be exported to a single 650 MB CD.

All exporting functions, either to the floppy or CD, can be com-

pleted while simultaneously recording and viewing live video.

A CD-R type disk can be used for copy without formatting and

is recommended by Vicon. However, a CD-R/W disk must be

formatted in the AurorAcorD unit and can be quickly erased for

reuse.

Serial Communications

Two serial ports are provided that are configurable for RS-232,

half duplex/simplex RS-422 and 2-wire RS-485 AurorANet pro-

tocol. These ports are used for the support of a host computer,

uploading software upgrades, receiver communications, and

AurorANet compatible devices.

PTZ Control

AurorAcorD features full telemetry control (PTZ). Using the

front panel keys, the AurorAcorD can remotely control up to 16

Vicon camera domes/PTZ drives using RS-422/485 protocol.

Display Options and Performance

AurorAcorD can play back recorded video through a VGA mon-

itor output or a standard digital BNC output. The VGA output

provides a horizontal resolution of 720 pixels (540 TVL) and the

digital BNC output provides 640 pixels (480 TVL) resolution.

A third video output, the spot monitor output, is a non-digital

output used to display one camera or a sequence of all system

cameras. Sequencing of cameras can be done in any order. In

addition, AurorAcorD features two video looping connectors for

convenient looping of input video to other devices. Two looping

cable assemblies are provided in the accessory kit.

AurorAcorD provides a large variety of multiscreen options for

live or playback through the VGA or digital BNC output. These

multiscreen options include: picture-in-picture (PIP), quad

split, 3 × 3 (9 screen segments), 4 × 4 (16 screen segments), and

various combinations of quad- and sixteenth-sized segments.

Video may be sequenced in individual video sectors in multi-

screen modes. In all of the multiscreen displays, any camera may

be assigned to any of the screen segments. There is no fixed par-

titioning of camera input to screen segment. Also, any screen

segment may be made to sequence multiple cameras. If sequenc-

ing is selected, the cameras assigned to the sequence may be put

in any order, and selected cameras may be sequenced with

greater or lesser frequency than other cameras in the sequence.

Each camera channel can be given its own title of up to twelve

characters in addition to a time and date display. Additional

display information includes an alarm status display that indi-

cates whether the alarm source is a hardwired input, motion

detection, receiver alarm, receiver communication fail or video

loss. Titling is available on any monitor. Date information may

be displayed in the American, European, or Asian formats.

AurorAcorD includes an automatic daylight saving feature.

AurorAcorD allows the user to digitally magnify live or record-

ed images on a linear scane from 1× to 16×. The magnification

uses a proprietary interpolation technique which minimizes

blocking and pixelation in high-magnification.

NOTE: Electronic zooming is not the same as optical lens zooming.

In photographic zooming, the telephoto setting looks at a smaller

part of the original scene and thus can capture more detail than

would be seen in a wide-angle view of the scene. In electronic zoom-

ing, a segment of a picture of the original object is enlarged.

Consequently, only the detail that was in the original picture is

enlarged; no additional detail is seen. This is true of all electronic

zoom devices.

Alarms

AurorAcorD offers versatile, multi-faceted alarm functions.

There is one hardwired alarm contact for each camera channel

(total 16), and each may be used as an alarm input or output.

Inputs may be set for normally open (NO) or normally closed

(NC) operation, and outputs may be set to active high or low.

Alarm inputs may be defined as latching or momentary. Alarms

may be acknowledged automatically or manually. Digital video

motion detection is provided on each camera channel, and all

channels are protected by a video loss alarm feature. Sixteen

receiver alarms are available (these alarms are always latching).

Alarm outputs include a tone, a special display of the alarmed

video, the word ALARM displayed on screen, a front-panel

LED for each alarmed channel and dry contact relay outputs

(NO and NC).

Motion Detection/Museum Search

AurorAcorD features video motion detection in all display for-

mats. Detected motion on recording video may be used to gen-

erate alarms or to increase the overall system-recording rate and

quality, or to do both. The video picture area is divided into 192

motion detection blocks. Detection may be enabled or disabled

for each block, and each camera channel may be programmed

for the minimum number of blocks that must detect motion

before the motion detection outputs go active. In addition, the

detection sensitivity level may be set on each camera channel

over a relative range of 1 to 9.

AurorAcorD features museum search. Museum search is applied

to playback video. Motion can be detected at an accelerated

playback rate using all the detection block features of motion

detection without having to review all video at the recorded rate.

Programming

AurorAcorD is programmed with user-friendly on-screen

menus. AurorAcorD's on-screen menus lead the programmer

step-by-step through the various programming functions. A very

important feature of AurorAcorD’s menu system is the ability to

set the background to “video” or essentially make it transparent

while viewing the display. This feature applies to all 3 monitor

outputs and allows the convenience of programming while

monitoring video. Another very important feature of the
