Maximising Security with Intercom and Door Entry Systems: A Comprehensive Overview

In the course of installing your system, we will take into account all factors and leave your premises without any marks.

 There are three basic components of an intercom system: a master station, a substation, and wiring.

      • Location of the intercom system: You need to determine where you want to install the intercom system. Meanwhile, Polytech staff will advise you to take the best choice.
      • Wiring requirements: If you choose a wired intercom system, you must run cables from the main station to each substation.
      • Power source: While wireless systems may use batteries or a plug-in power supply, wired systems normally need AC power
      • Integration with other systems: The integrated intercom system, which has a modern and simple design, is a reducing replacement for analogue intercom systems. This type of system’s basic capabilities can be combined with existing motion detection, fire detection, and video monitoring installations to provide a unified security solution and automation.  

If you have other home automation systems, such as a security system or smart home devices, you may want to choose an intercom system that integrates with these systems. 

Polyteck has the experience and the ability to integrate already existing intercom systems with new ones achieving a unified security solution.
