Hamilton County, OH Police Communications

HAMILTON COUNTY COMMUNICATIONS SYSTEM

The Hamilton County Communications Center is located on U.S. Route 127 (Hamilton Ave.) just south of I-275 (their antenna tower can be easily seen from 275). The communications center is staffed and run by the Hamilton County Commission, the dispatchers are not members of the Sheriff's office. The dispatch room is manned by 5 dispatchers, 4 of which dispatch for the Sheriff's Office, while the fifth dispatches fire for the various community fire departments. The dispatch room also contains the Emergency 911 phone operators who take the emergency calls. For communication purposes Hamilton County is divided in to 3 sectors as follows:

EAST SECTOR - Clermont County line to U.S. Route 42 (Reading Rd.)

CENTRAL SECTOR - U.S. Route 42 to U.S. Route 127 (Hamilton Ave.)

WEST SECTOR - U.S. Route 127 to the Indiana State line

These sectors run south from the Butler/Warren County lines to the City of Cincinnati Corporation line.

Hamilton County Police service unit numbers use I-75 as an east/west dividing line.

In July 2003 Hamilton County went on-line with their new 800 MHz Motorola APCO-25 9600 Baud trunked radio system.
Currently there are only three scanners on the market capable of monitoring this system. For more information click on the
