Downlook Video System
The Downlook system is the first fully integrated Video and Alarm transmission system to utilize
standard alarm control Panels and Central Station Receiver.
The Downlook system provides for the transmission of video images over standard telephone
lines or a cellular connection.
Communication of the video images takes place with the communication of the event
information, video images can be sent with: alarm conditions - holdup - opening and closings equipment failure, etc.
The Downlook Video Transmission Module can be connected directly to one of the following
DSC, Partner or Sur-Gard alarm panels or Communicator.

Partner P600
The Downlook Video Receiving Module connects directly to the Sur-Gard MLR2* Digital Central
Station Receiver. One Video receiver module works with one Digital receiver line.
Communication is over standard phone lines and not expensive or prohibitive Data lines.
The Downlook video system can be easily added to an existing location by simply changing the
alarm panel or adding an interface communicator. Existing video cameras can be utilized as
Downlook does not require special cameras. Simply taking a video output from a looping
switcher or monitor will provide the required video.
Video Compression and Transmission is produced by the DLM-4/DLM-4L module, Video
receiving is provided by the MLRV-A Module with PC storage, printing and retrieval via the
Downlook Grabber Board and Downlook PSA software.
Downlook is the leading Video Integration - Verification - Confirmation system, designed
specifically for the security industry and utilizing standard security equipment for the capture,
program, communication and display of video.
Visual Verification is the most accurate method of determining if the information communicated
to a Central Station is correct. Providing Video Verification to a Central Station can result in the
maximum response by the emergency services and can help in the reduction of false alarms.

DLM-4/DLM-4L
Video Transmission Module
The DLM-4 is the video capture, compressor and transmission module and must be used on all
Downlook applications, the DLM-4 connects to one of the listed Alarm Panels, Communicator or
with the DLM-4L onto the Power 832 - 5108L Module.
One single BNC post provides for a direct single video connection with 75 ohm termination.
The DLM-4 can capture and store 4 video pictures and transmit those images when instructed
to do so by the Alarm panel or communicator. Time of first image capture is programmable in
the control panel and the time spacing between additional captures is fully programmable on
the DLM-4 by way of dip switches.
A programmable time for first image capture allows for the flexibility of Downlook activation from
Infrared detectors, Door contacts, Hold up buttons and glass break detectors.
A rotary feature provides for alternate image capture for up to four cameras.
All DLM-4L function and features are programmed into and provided by the Power832 control
panel.
E.g. If used with two cameras, on a common alarm condition the first image will be taken by
camera one, second by camera two, third by camera one, fourth by camera two.
Dip switch selection provides for a switched output on camera supervision, after the cameras
are connected and power applied disconnection of a camera or loss of video signal will result in
the output changing state.
No Video adjustment or calibration is required. Power requirements are 10.5 - 16 VDC; 300ma
@12V.
