I - 1. Introduction
VisorNet 4c is a digital transmission device for video signals over IP protocol for
remote surveillance.
VisorNet 4c incorporates different alternatives for IP network connections through
links that can be: Integrated Services Digital Network (ISDN), an Ethernet Local Area
Network, a point-to-point Frame Relay Network or any other WAN type up to 2
Mbps, and even the Public Telephone Switch Network (PSTN) through an external
modem.
This variety of networks combined with the universal use of the IP protocol permits
the use of the device in a wide range of scenarios.
VisorNet 4c configuration is carried out through forms contained in various web
pages that offer an integrated server in the device itself. The forms permit rapid
introduction of all the device operation parameters.
VisorNet 4c permits you to access video images from up to four different cameras
from a remote PC. Depending on the network bandwidth, the device selects the most
adequate video quality.
Through the six inputs, the VisorNet 4c can detect alarm device activation
(Volumetric, fire sensors, alarm switchboard etc) and capture a sequence of images
from any of the four cameras. VisorNet 4c at this point uses the existing
communications link in order to transmit an indication of an alarm situation to an
Alarms Control Center or to the Telesurveillance Center. Together with the alarm
situation indication, the device sends the sequence of the captured images from the
appropriate camera, which aids early detection of false alarms.
VisorNet 4c has two relay outputs available through which you can activate or
deactivate the external devices.
A key slot with four positions is situated on the front panel and permits VisorNet 4c
programming. There are two pre-saved programs (“Day and Night”), which identify
with two key positions and permit you to establish two security levels or different
performances. Choosing the “Auto” position key enables the VisorNet 4c to activate
one of the two programmed timetables. The fourth key position deactivates the
device.
The possible VisorNet 4c deployment scenarios are varied. Among those that stand
out is the one that is displayed in the following figure:
