3G
3G is the next generation cellular GSM network and is expected to become the main technology used for the transmission of alarm signals to a Central Monitoring Station.
Cellular Backup
As the use of video images for verification of alarm events becomes more widespread, 3G is the technology of choice where a backup path to the monitoring server is required. 3G networks offer bandwidth far in excess of todays 2G GPRS/EDGE networks and are capable of streaming live camera images.

The Cisco WRP400 wireless router has everything you need to future proof your security system way beyond the expected 2017 expiry date for both PSTN landlines and cellular 2G networks.
Start using the built in VoIP ports to safely transmit signals over your DSL Internet connection today and rest assured that once cellular 3G plans fall within your budget, the WRP400 will allow you to plug in a USB modem and provide seemless failover to the monitoring center when your DSL internet fails.
A one-off $29 provisioning fee provides you with a unit that will transmit alarm signals to a Central Station over your DSL connection when good and over a wireless 3G connection when your DSL goes down or your line is cut.
