An intercom system is a two-way communication electronic device that contains circuitry for the purpose of transmitting and receiving audio and/or video transmissions.
With the advent of cellular communication, digital telephone systems, and other communication devices. However, there are lots of applications where these devices work better than anything else. There are a very wide variety of systems available at Real Summit Office as defined below:
Difference Categories of Intercom Systems as Available at Real Summit Network are:
Wired or Wireless Intercoms
Wired Intercom Systems: When you can run wires between locations, a wired system can give you a little more privacy and eliminate possible interference from neighboring systems. There are different wire types such as 2-wire shielded or Cat-5/6 that can be used with these systems. If you are considering a video system, a wired unit may be the best solution we can provide for you.
Most intercom systems have traditionally been the "wired" type that require low-voltage wiring be installed between each of the Master Stations and Sub-Stations. Wired intercom systems tend to be very reliable and require very little maintenance. Because of this, wired intercom systems have long been the preferred choice of most commercial and industrial users.
In applications where wires cannot be run, a wireless system is used. Intercom systems are available that allow "wireless" communications between Master Stations and Sub-Stations. These systems typically use radio signals to provide the communications path between stations and don't require any type of wiring.
There are a broad spectrum of two-way wireless communication devices that include such devices as handheld radios, outdoor wireless callboxes, as well as traditional desktop devices. The range these units will transmit varies widely based on the wireless technology used.
Video Intercom Systems
These critically adopt a unit that has a camera, speaker, and a push button that goes at an entrance door, and an internal monitor unit that can communicate with the entrance unit. Some systems can have multiple video monitors internally
They therefore incorporate video surveillance features. Video intercom Sub-Stations are similar to regular Sub-Stations except that they also include a small built-in video camera that provides a direct view of the person operating the station. Most cameras offer a fixed viewing angle; some cameras can be moved up and down and right and left by the person receiving the call. This monitor is used to view the image produced by the camera in the video intercom Sub-Station.
Given the difficulty of sending video over the airwaves at very much distance without interference, most available units are wired.
Apartment Intercoms: This type of system has a door unit at an entrance door and then each apartment or flat has either one or multiple units that can speak to the door and possibly see the visitor, or the door unit rings a landline or cellular telephone number. A visitor simply presses the correct button for the apartment they want to speak to, and the tenant can speak back and then press a button to unlock the door.
Two-Way Radios: While these are technically not intercoms, there are two-way radios that communicate with base station intercoms. So you can have the flexibility of a mobile radio that communicates over long distances mixed with the capability a fixed intercom gives you.
Real Summit Cable Network are equipped with intercom systems provision and installations, which can be done in the following ways:
