Intercom – PoE – PABX System……….
An intercom (intercommunication device), talkback or doorphone is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles.

How do IP intercom systems work?

The transmission of voice and images over Ethernet and by IP is increasingly replacing analog and ISDN-based transmission technologies. Voice communication and image are converted into digital signals and then transported over the IP network by means of a specific protocol such as SIP.
Typically, SIP is directly implemented in IP intercom systems with the necessary Ethernet interface.
Other adapters or converters are unnecessary. This is especially advantageous in companies which already have IT networks and structured cabling as it allows easy integration of the IP intercom into the existing environment.
Existing IT resources can be used without the need for an additional network. The network cable also provides power to the IP intercom system via PoE. Alternatively to a cable connection, intercoms may be operated over WLAN. In that case, obviously no network cable is required but consequently a separate power connection.
IP phone systems: Intercoms are self-contained and therefore operate free of the public phone system.
Intercoms are generally permanent fixtures in the space that they connect to another via communication and utilize hardware such as walkie talkies, telephones, public access loudspeaker systems, and wall mounted speaker and phone systems.
Some, but not all intercom systems are also attached to security systems, allowing for access control functions within the intercom itself.

 

There are several basic forms of intercoms:

Master or Base Station: The master or base station of an intercom system is an intercom base which has the capability to make announcements to the entire system and also has the capability to connect with any system within the intercom system. So, although a business owner may wire certain intercoms to connect with only certain others, the business owner him or herself may connect with any and all intercoms within the system.
A Door station intercom: system is a system that is situated at the door of an office or home that is capable of making contact only with the main or base station. The door station may not intercom individual intercoms within a building; it only communicates with one base station). This is commonly used in security systems as a means of controlling access to a space.
A handset:  is a portable intercom that does not have a headset mechanism attached to it. Instead it functions like a portable telephone or a walkie-talkie.
Many modern office telephone systems offer an intercom function, which allows for a closed-circuit intercom messaging system across desks. In many such devices, the ring that signals an incoming intercom correspondence is different than that which indicates an incoming call from an outside source. The intercom system on a telephone does not utilize the outside phone system.
Many intercom systems are hardwired into a building or set of buildings. However, for installations where hardwiring is not possible or desirable, wireless intercom systems do exists. It should be noted that in the case of wireless intercom systems, there is a risk of interference from other systems.

 

 

Our Work Scope – Planning, Installations & Delivery

 

Customers can contact our technical team for inquiry, and first to table the need for their security system requirements. To this end WESTCOT-GULF can arrange a site visit, for inspection, and parameter array, and develop a blue print to best suit the customer’s requirement, and offer input for security options and an installation schedule.
Our installations and maintenance projects are highly customers friendly, well planned from Site Inspection, Technical Design, Analysis, and down to Implementation, to minimize security risks, and focuses on cost efficient delivery with the least possible disruption to the customers operations.
All our installations are carried out by WESTCOT-GULF certified installers and a Hi-Tec Supervision by our affiliated Original Equipment Manufacturers.
The final phases are. . Test-Running, Training of personals and Commissioning
