Intercom systems


A doorking telephone entry system is a significant component for an access control security system for your business premises’ security infrastructure. It serves as a doorbell and intercom to give you control over who enters the site. At the same time, it acts as a security system for controlling staff access throughout the building.
There is a broad range of door telephone entry systems on the market, which means you have great choice and flexibility:


An intercom (intercommunication device), talkback, or door phone is a stand-alone voice communications system used within a building or a small collection of buildings. It’s a two-way communication electronic device that contains circuitry to transmit and receive audio and video transmissions. Intercom allows people to speak into a microphone to be heard on a speaker by people in a different room or area.

Intercom solutions have long outgrown the image of the single-linesingle-button door buzzer panel. In a wide range of communication and building management settings, the intercom is emerging as the future central hub technology that brings together audio and video communication.

Different types of intercom security systems:

Wireless Intercoms

Wireless intercoms are using where cannot run wires. There is a broad spectrum of two-way wireless communication devices, including handheld radios, outdoor wireless callboxes, and traditional desktop devices.


Wired Intercom Systems

Wired intercom access control systems give you a little more privacy and eliminate possible interference from neighboring systems. Different wire types, such as 2-wire shielded or Cat 5/6, can be used with these systems.


Video Intercom

Most available units wire. These typically have a team with a camera, speaker, and push-button at an entrance door, and an internal monitor unit that can communicate with the entrance unit. Some systems can have multiple video monitors internally, given the difficulty of sending video over the airwaves at much distance without interference.


Apartment Intercoms

This type of system has a door unit at an entrance door. A visitor presses the correct button for the apartment they want to speak to, and the tenant can talk back and then press a button to unlock the door. Then each flat has either one or multiple teams that can speak to the door and possibly see the door unit rings a landline or cellular telephone number.


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.


Security intercom systems

Security intercom access control systems are using to provide voice communications between two or more locations for security purposes. Security telephone entry systems are frequently using between a locked building entrance door and a constantly attended area.


Some telephones include intercom functions that enable paging and conversation between instruments of similar make and model. A single device can add intercom functionality to multiple standard telephones on a typical phone line, even of different makes and models. Installation effort is minimal and is not vulnerable to the radio interference and security issues of wireless systems. Intercom paging is accomplishing by sounding a distinctive ring from all telephones after any phone is taken briefly off-hook off the hook. After paging, any number of phones may converse. During intercom use, one can hear an external call’s ringing signal in the earpiece. The device temporarily disconnects the external phone line during intercom use and reconnects when all phones are again on hook.


The TEC1 provides basic telephone entry system with the SES advantage. TEC1 series offers 2 or 4 line displays and five capacities: 50125250500, and 995 to match your requirements. The “CA” models have card access capability and include the modem and CELCOM essential software. The display is easily read in direct sunlight or at night. As with all SES telephone access control systems, the TEC1 series has board-level surge suppression at no additional cost. The stainless steel front door and aluminum back box are sure to provide years of durable service. Designed to the same high standards as the TEC and CAT product lines, the TEC1’s come with a two-year limited warranty. The best of basic telephone entry, with unmatched SES quality.



SES VoIP/SIP Interface (“SVSI”) allows SES CAT and TEC series to call residents using VoIP and eliminates phone line or cellular service costs. When a visitor dials a resident on a CAT or TEC series unit, the call is passed through VoIP in the cloud access system system to dial the resident. On answering, the resident can talk to the visitor and then press the Open Door touch tone on their phone to grant access. As in all VoIP applications, the “SVSI” interface only needs internet access through a local router, a phone connected directly to the CAT/TEC, and power. Can set up voIP services with Google Voice (free) or from a list of other VoIP providers.
