MODELS AND PRODUCT CODES
DigiTek is designed to detect changes in video by comparing Model Number
Description
a current scene to a reference scene held in memory. An intruder in the scene causes a change in the video level compared to the reference scene. If this change exceeds a specified threshold level, the intruder may be highlighted and triggers an alarm. Highlighting may be enabled or disabled.
A video image input from a camera is divided into more than 3700 rectangular blocks or cel s and each block is subdivided into 4 × 4 pixels. One image from each camera is stored as a reference, and the reference image memory is updated at a frequency set by the Product specifications subject to change without notice.

CONTRACTORS’ SPECIFICATION
MULTICHANNEL DIGITAL INTRUSION DETECTORS
The digital intrusion detector shall detect changes in the video images being generated by the cameras connected to it by comparing each incoming frame to a reference frame held in memory. If the incoming frame has changed, to exceedspecified threshold parameters, the changed video shall trigger an alarm. The sensing area shall have more than 60,000sensing points divided into more than 3700 separate sensing cells. The smallest area that can be programmed to detectintrusion shall be one cell; the largest area shall be the full monitor screen, excepting a narrow margin at the edges of thescreen. It shall be possible to program multiple sensing areas per camera input channel.
The reference frame update rate shall be user-selectable from 0.0 to 127.5 minutes in 0.5 minute increments. The minimum intrusion time shall be user-selectable from 0.00 to 15.00 seconds in 0.25 second intervals. The minimum intrudersize shall be user-selectable from 1 to 256 cells. Highlighting active cells during an alarm condition shall be user-selectable.
The sensitivity of the sensing zones shall be user-selectable, with options including automatic or manual settings and indooror outdoor settings. In the manual mode and in the auto/indoor mode, there shall be a choice of eight sensitivity levels. Inthe auto/outdoor mode, there shall be six levels of sensitivity. Alarm video output to the recorder shall be selectable fromnormal, interleaved, or alarm-only modes.
The intrusion detector shall accept monochrome and color composite video inputs and shall have two monitor outputs.
All programming shall be done from on-screen menus. A real-time clock and a scheduling program for active detectionperiods shall be provided. On-screen displays shall include camera numbers and titles, monitor titles, time and date, thecurrent sensitivity level, the number of currently active cells, the status of the sequential switching function, and alarminformation. The user shall be able to select black or white letters, with or without a contrasting outline. The user shall alsobe able to enable or disable a transparent tinted background for the screen titling displays. There shall be multipleuser-selectable modes of displaying time, date, and title information, and individual elements may be included or excludedfrom the display. Each monitor may have its own titling program.
In addition to motion-based alarms, the intrusion detector shall also provide one hardwired input for each camera input.
Alarm outputs shall include one hardwired output per camera, and relay outputs to activate additional equipment such as aVCR shall also be provided. Alarm annunciation shall include a flashing red LED, an on-screen message that identifies thealarm channel number, and an audible tone. The user shall be able to enable or disable the flashing display of cells activatedby an intrusion. The user shall be able to enable or disable the screen message and audible tone. An additional alarm shallactivate if video is lost from any input channel while the detector is powered up.
The intrusion detector shall be able to sequence video on both monitors, with each monitor having its own sequencing program. It shall be possible to sequence the cameras in any order and to have individual dwell times for each camera.
The intrusion detector shall be available in model variations accepting four, eight, and sixteen video inputs. It shall measure not more than 1.73 in. (4.4 cm) in height, 19.0 in. (48.3 cm) in width with rack-mounting brackets installed, and 9.25in. (23.5 cm) in depth. Its weight shall not exceed 8.91 lb (4.04 kg). The digital intrusion detector shall be one of these Viconmodels: V704-IDS, V708-IDS, or V716-IDS.
