Wireless Intercoms: More Than Just A Door Phone
When one thinks of wireless intercoms, more often than not, a door phone pops in mind. True, the two terms are related but a door phone is just one of the many applications of wireless intercoms. Aside from a door phone, here are some other wireless intercom devices and their applications: Baby monitor. Baby monitors come in many forms: audio or video or both and one-way or two-way communications. Wireless cameras can also be included in this category and these intercoms can also be used for security monitoring and surveillance. Walkie-talkie or two-way radio transceiver. Developed in WWII, two-way radios are now very popular for personal and business use. The Family Radio System (FRS) that is usually used by two-way radios is unlicensed and FRS radios are mostly mass-produced and are a low-cost alternative for the business band. Under normal conditions, with few obstructions in line-of-sight, the range of FRS is about a third of a mile. In business, two-way radios are usually used by security and other roaming personnel. Other industries, such as care-giving services, events organizing and TV or movie productions also use two-way radios. Callbox. A callbox can function similarly with a two-way radio but it is usually mounted on a fixed location, usually in unmanned areas. Common uses of a call box are for construction sites, golf courses, hotels, hospitals, parking lots and gated entrances. Customer service callboxes are also used in large stores with unmanned areas. Some callboxes have a gate relay. Public Address (PA) System. The system consists of a receiver and a speaker wherein a base station intercom or a handheld radio is used to deliver voice messages. This is used in public areas for announcements and for emergency management. Alert Systems. There are some detection devices that can be integrated in the wireless intercom system. Examples of these are metal detectors and motion sensors that can send an alert signal to a handheld radio or a base station. A common application for these devices is for security. Hunters also use motion sensors for scouting areas and monitoring animal trails. Because the word “intercommunication” is very general, intercoms have taken many forms and purposes. Take the wiring out of the intercoms to make them portable and transmit data or signals through radio waves, and the number of applications of wireless intercoms increases even more. |
