If you’re looking for the longest range wireless outdoor intercom, there is really only one type of system that will meet your needs. That is assuming by long range you mean more than 1000 feet.
The outside wireless intercom system we put together for our clients is based on the MURS callboxes we offer. These callboxes can communicate at ranges of up to two miles. They are not inexpensive products, but unfortunately an inexpensive option doesn’t exist where long range is needed.
These MURS outdoor callboxes communicate with our MURS Commercial Intercom or our MURS 4-Mile Range Intercom base stations, or available handheld two-way radios we offer. That gives you the ability to configure a system with stationary or mobile radios.
By combining these products you can put together the longest range wireless outdoor intercom system available.
