The touchscreen of an embodiment includes a battery backup system for a security touchscreen. The touchscreen incorporates a standard Li-ion or other battery and charging circuitry to allow continued operation in the event of a power outage. In an embodiment the battery is physically located and connected within the touchscreen enclosure. In another embodiment the battery is located as a part of the power transformer, or in between the power transformer and the touchscreen.
The example configurations of the integrated security system described above with reference to FIGS. 5 and 6 include a gateway that is a separate device, and the touchscreen couples to the gateway. However, in an alternative embodiment, the gateway device and its functionality can be incorporated into the touchscreen so that the device management module, which is now a component of or included in the touchscreen, is in charge of the discovery, installation and configuration of the IP devices coupled or connected to the system, as described above. The integrated security system with the integrated touchscreen/gateway uses the same “sandbox” network to discover and manage all IP devices coupled or connected as components of the system.
