The Indian Hill Rangers have been directly monitoring alarm systems for the residents of Indian Hill more than 40 years. In 2014,, this monitoring system was replaced with state of the art technology that features redundant systems and automated supervision, making it more reliable. Within seconds of an alarm system activating, a monitor alerts Ranger dispatch. This system does not require phone lines or cellular service, instead it uses a special, licensed radio link provided by Koorsen Fire and Security. The total fee for this monitoring is $21 per month. If you would like more information about having your alarm system monitored by the Rangers, please call 561-7000.
