Alarm Installer Guidance
Emizon IP makes transition to the digital/IP environement easy and profitable. Designed specifically for broadband/IP networks, Emizon is good news for both installers and end-users. End-users are able to leverage their broadband investment; its faster speeds, improved functionality and reduced costs while still maintaining the highest security standards. Installers are able to provide a secure, cost-effective signalling service that is easy to fit and maintain. In addition by exploiting the added value features of Emizon's online servicing option they can also provide better and cheaper customer service.
With a planned programme of upgrading customers with legacy signalling systems to Emizon IP you can protect your customers and create business advantage; call us on 01858 575754 to find out more.
Here we take a look at some key pointers for alarm installers when moving to Emizon IP.
Signalling Paths
Emizon IP is a dual path service. The primary (wired) path connects directly into the customer’s broadband/IP network via the Customers router or Ethernet network connection. The secondary (wireless) can access the four leading GPRS network providers in the UK, Vodafone, 02, Orange and T.Mobile.
The Router
A router is used to connect different devices such as computers, faxes, and or alarm panels on the same site to the internet over the same broadband connection. The router will assign each device a unique (internal) IP address (e.g. 85.123.23.45) so that it can direct data across the internet to and from the correct device. All devices need an IP address to communicate across the internet.
DHCP (Dynamic Host Configuration Protocol)
Routers use the DHCP system to assign IP addresses to devices that they connect over the internet. This is usually done automatically by the router once the connected device (e.g. a Bosch, Pyronix or Emizon TCD) is powered up. Any IP address assigned using DHCP will be dynamic, because it can be changed at the request of the service or device.
The DHCP system is usually used in residential and small to medium business premises without a dedicated IT or Network function. Here, because the IP address is assigned automatically, the TCD is designed to connect automatically, and there is no need for any additional action by the installer.
Static IP Address
Most often used in larger premises with an IT department, or where a 3rd party is contracted to manage the network.
As the name suggests, a static IP address does not change, and is assigned to the device before it connects to the router. Because all devices must have a unique IP address the system requires a system administrator to allocate and track the static IP addresses used.
When using a TCD within a Static IP address system, you will need to complete the Customer IT Survey Form (link) which records the details required i.e. IP address, Netmask and Gateway numbers. On receipt of this information Emizon can input the required IP address into the TCD remotely, via the wireless GPRS path in a matter of seconds.
TCD and Network Security
The TCD uses outbound TCP/IP connections only in the IP destination rage of 18,000-18,049 via the landline IP (Ethernet) and GPRS IP networks. The TCD does not accept inbound connections and does not require any inbound IP ports to be opened up on the customer’s firewall or router. The TCD also contains an internal firewall to isolate it from any unauthorised connections or IP traffic.
