Radio encryption in Mercer County
Nothing monitored in Mercer County remains in the clear. All 22 talkgroups logged across the Mercer County Interoperable Public Safety Radio System and the New Jersey Interoperability Communications System (NJICS) are encrypted. Three agencies appear in the record, all using P25 AES-256: Ewing Township Police, verified as fully encrypted; Trenton Township Police, listed as fully encrypted but unverified; and the Mercer County Sheriff, listed as partially encrypted and also unverified. With two of three agency records unconfirmed, the department-level detail is weaker than the talkgroup count, but the talkgroup count is unambiguous — a scanner will not receive monitored public safety traffic in this county.
