Intercoms provide a means of identifying visitors at your premises without having to remove any barriers between you and them. While audio devices (such as phones) allow for good interaction, adding video allows the user to gauge the situation outside visually as well, being able to check the circumstances as well as the visitor. Both wired and wireless systems are available. Wired systems are more labour intensive to install, but the direct power supply ensures lower operational costs and higher reliability. Wireless systems on the other hand are more flexible, and ease of installation is better for non-technical persons.
