Introduction
The V4000 captures and stores video images (ME-JPEG's) for transmission to a central
station for visual verification of alarms. Images are transmitted over standard telephone
lines using an internal modem. The capture of images is initiated by a zone violation in
an associated control panel. Specialized Control Center Software allows the user
configuration options including pre-trigger/post-trigger on alarm, frame capture rate, and
image resolution. Refer to the Control Center Software User Guide for additional
details.
Basic Operation
Video information from the 4 video inputs is initially formatted into an ME-JPEG format
and stored in an on-board buffer. Subsequent video captures store only the difference
data required to assemble the frames captured. When the buffer is full, the data is
continuously updated by writing the new data over the old data. This process ensures
that a recent history is maintained in memory before an alarm event occurs. The buffer
allocated to on-going storage is programmable using Control Center Software. When
an alarm event occurs, the control panel calls the central station to report the alarm and
then signals the V4000 via the control panel's keypad (ECP) bus. The remaining video
buffer memory is used to capture the event. When the remaining memory is filled,
recording of video events ceases. After the central station call is completed, the V4000
takes control of the phone line and calls a previously stored number for the central
station that will process the video signal. The completed video clip including the pre-
alarm video and the post-alarm video is transmitted to the central station using the
internal modem.
Note: Central Station calling and transmission of video by the V4000 is independent of
the control panel. If a subsequent alarm event occurs during video transmission,
the transmission will be terminated and the control panel will seize the phone
line to forward the alarm information to the central station. When the call is
completed the V4000 will resume its call to the central station and transfer the
video data. Contact your central station to confirm support for OzVision™ video
transmission protocol.

Video data can also be retrieved by accessing the module via telephone with a PC
using Control Center Software and utilizing the module in a streaming video
mode.
