VIDEO ALARM
VERIFICATION UNIT
VIVER
viver_en 09/08
The VIVER module provides remote video alarm verification, based on image sequences
transmitted from cameras installed in the protected facility. The device is designed to be used
with the STAM-2 monitoring station with video verification option enabled. Communication
can be effected through the Ethernet network only, or through the modem only, or through
both the network and modem.
1. Module features
•
4 video inputs for connecting CCTV cameras.
•
4 transmission triggering inputs.
•
4 transmission unlocking inputs.
•
Buffering image sequences from cameras.
•
Optional “live” view of the protected facility.
•
Built-in TCP/IP communication interface.
•
Built-in 56k modem as a reserve communication channel.
•
PC software for module configuration.
2. Operation
The VIVER module has 4 inputs (VA, VB, VC, VD) to which the protected facility cameras
can be connected. Images from the cameras are stored in the module memory in the real
time mode. On violation of any of the transmission triggering inputs (INA, INB, INC, IND),
the module will inform the monitoring station of the event and will start sending the sequence
of pictures recorded into memory before the input violation. At the same time, it will record the
corresponding sequence of pictures after the input violation, which will also be sent.
The module is capable of sending up to 255 pre-event images and up to 255 post-event
images. Having received the event information, the monitoring station operator has
a predetermined time period (0-240 seconds) to invoke the live view of the protected facility.
Sending the alarm sequences has priority over the live view – if there is a new violation of the
triggering input during the live view from the given camera, the live view mode will be
stopped. A next image sequence will be sent to the monitoring station and a corresponding
event will be generated. As long as the module is gathering images from the camera on
violation of the triggering input, another violation of the same input will be ignored. Only after
a sequence of images is sent, a new violation of the same input will generate an event and
initiate the process of image sequence sending.
Sending data to the monitoring station is done synchronously, i.e. the module is sending
images by one from each triggered camera, starting from the oldest image.
