At Lekruise Solutions Company we install 3 types of intercom systems
In these type of installation wires are used to connect and install devices. Wired systems are best to be installed when the building is still under construction so that the wiring can be made within the wall . They may be installed in completed buildings but tend to be costlier and may not be as neat . They have an advantage of not being prone to interference.
As inferred by the name, they do not involve wiring and can be used without installation of components. Wireless intercom make use of radio frequencies for transmitting signals. These systems are prone to interference causing problems. Interference can be caused by distance involved as well as brand and quality of equipment. Most of the wireless intercom systems come with a portable receiver that can be used from different locations.
These are essentially wired intercom with wireless receivers. The difference from normal wired intercom and wired/wireless is just the receiving device which comes with a cordless handset enabling the user to carry it around away from the receptor base.This combines the advantages ot wired and wireless by ensuring signal strenght(around the base) and ease of movement.
