** As with all wireless products the maximum range is determined by the amount of interference between base stations. Any solid obstruction between a direct line of sight range will reduce the distance of the signal between the individual base stations. For maximum distance reduce as much interference as possible.

Primarily purchased just before wife had lumbar surgery where I could be reached anywhere in house including downstairs. It works. To test on back of our 9 acre property. Have not had time;however, range off property either direction is approximately 1/2 mile. These replace Radio Shack intercoms which were extremely unreliable. Satisfied with purchase. May link to alert zones when I have the time. James
