Outdoor intercoms are available in both wired and wireless versions. The wired intercoms are most often used at external doors where people at a fixed location inside the building need to monitor the door for visitors.

Wireless outdoor intercoms not only have the benefit of not requiring installation of cable, they also allow for mobility of the person or people monitoring the outdoor wireless intercom. Some of these devices communicate with handheld two way radios and others with portable wireless intercoms.

A wireless outdoor intercom faces some difficult challenges. Most obvious is the weather. Not only is there moisture to worry about, but also extreme heat and cold. You need a wireless intercom that can withstand exposure to the elements.

Another factor is the range you need to cover. How far apart are the intercoms going to be? But it’s more than just distance. Building construction can greatly reduce the distance a wireless intercom will communicate. A wood-framed building with siding will reduce the range less than a concrete or brick building.

Depending on where you put the wireless exterior intercom you may also have to worry about vandalism. You need to ask yourself whether someone will attempt to steal or destroy the unit. If so, then you need a unit built to resist vandalism.
