Oakland County Emergency Management

Oakland, Michigan

How we verified this

Oakland County's dedicated Emergency Management channels ('Oakland EMD 1' and 'Oakland EMD 2,' both tagged 'Emergency Management - E.A.S. Alerting / Tornado Sirens') are conventional analog (FMN) with no encryption, even though the county's separate MPSCS police dispatch is stated to be fully P25 encrypted. The 'Emergency Management' function specifically is clear/mixed, not fully encrypted.

Oakland County Context

Oakland County is a mixed picture: 9 of 18 agencies we track here are fully encrypted (50%), which means some neighboring departments are still audible on a scanner.

What This Means

Coverage here is uneven — parts of the system are locked and parts are open, so a scanner gives you an incomplete rather than an empty picture.

Frequently Asked Questions

Is Oakland County Emergency Management radio encrypted?

Yes. Oakland County Emergency Management uses P25 AES-256 encryption. Coverage here is uneven — parts of the system are locked and parts are open, so a scanner gives you an incomplete rather than an empty picture.

Can I listen to Oakland County Emergency Management on a police scanner?

Partially. Oakland County Emergency Management encrypts some of its talkgroups while leaving others open, so some channels may still be accessible. Check RadioReference for specific talkgroup status.

Why did Oakland County Emergency Management encrypt their radio?

The reasons offered are almost always the same two: officer safety and operational security. Whether either was tested against a real Oakland County incident is rarely part of the public record, whereas the consequences are easy to observe — no real-time accountability, and neighbouring agencies still in the clear left working around the gap.

Can Oakland County reverse the encryption decision?

Yes — nothing about the underlying radio technology forces this. It's a decision Oakland County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.

What can I do about Oakland County Emergency Management encryption?

File a FOIA request for Oakland County Emergency Management's radio recordings and encryption-decision paperwork, then show up to speak at a council or commission meeting. Find other residents or journalists in Oakland County who want the same access — state legislation requiring public radio access is the longer-term fix, but organized local pressure is what usually moves the needle first.
