Hi All,
Security and communications systems combine voice, data and video within a
structured system that often includes access control. Access control
identifies users and limits their access according to defined authorization
rules. Technologies employed in these applications include facial
recognition, card readers, keypads and computer-activated locks, door
panels, and more. Telephone entry control, plastic identification (ID)
cards, video ID equipment, radio frequency identification (RFID) tags, and
fingerprint recognition technologies are also available for use with
building security and communications systems. Due to the mission-critical
nature of these applications, network redundancy is essential in case the
primary network fails or is disabled by an intruder.
Integration with the building's existing Ethernet network for secured
access and central monitoring
Network redundancy to backup the security system in case the Ethernet
network goes down
*Solution Description
*
Moxa's solution used the building's existing Ethernet network as the primary
backbone and a cellular network for the backup solution. The OnCell 3100
series IP modem was used to develop the cellular network. A reliable backup
system is extremely crucial because if the Ethernet network goes down and
the security monitoring company is not instantly notified of the disruption,
a robbery can occur during the interval. Therefore, power redundancy is also
an important requirement for this project.
The OnCell G3100-HSDPA series of high-speed industrial-grade IP gateways are
intelligent and fully-featured wireless communication platforms that connect
your Ethernet and serial devices over a cellular TCP/IP network. The OnCell
G3100-HSDPA series offers connectivity to all tri HSDPA/UMTS frequency bands
and quad GSM/GPRS/EDGE frequency bands used in Europe and the United States,
allowing seamless global roaming on the best available network.
The OnCell G3100-HSDPA comes with private IP management software and
supports VPN for handling the IP address issue in cellular network
structures. The OnCell G3100-HSDPA also comes with a built-in relay output
that can be configured to indicate the priority of events when notifying or
warning engineers in the field. Two digital inputs also allow you to connect
basic I/O devices, and the OnCell G3100-HSDPA comes with redundant power
inputs to assure non-stop operation.
