Police Department Partially Encrypted Discovered via RadioReference

Ossining Township Police

Westchester, New York

How we verified this

The live Metro-25/MTA MRRS system page lists three Ossining PD talkgroups: 9600 'Ossining PD Disp' and 9601 'Ossining PD Tac' are clear (no encryption marking), while 9602 'Ossining PD Sec' is marked 'T Enc' (encrypted) -- a partial, not full, encryption posture, contradicting the recorded 'all' scope. Note the agency's real name is likely 'Village of Ossining Police Department'; New York has no 'township' layer of government of the kind implied by this record's name.

Frequently Asked Questions

Is Ossining Township Police radio encrypted?

Yes — Ossining Township Police's radio system runs on P25 AES-256 encryption. Some of this agency's traffic is encrypted and some is not. What you can hear depends on the channel and on what the department is doing at the time.

Can I listen to Ossining Township Police on a police scanner?

Partially. Ossining Township Police encrypts some of its talkgroups while leaving others open, so some channels may still be accessible. Check RadioReference for specific talkgroup status.

Why did Ossining Township Police encrypt their radio?

Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Westchester County where an open channel caused harm. The costs need no such documentation: reporting on police department response slows down, and mutual-aid coordination gets more awkward, immediately.

Can Westchester County reverse the encryption decision?

Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.

What can I do about Ossining Township Police encryption?

Contact the officials who oversee Ossining Township Police's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Westchester County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
