Verification Status

We don't yet have per-talkgroup data for Montclair Police from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at low confidence (50%) based on how closely the wiki listing matches this agency's name and county.

If you monitor Montclair Police directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

Frequently Asked Questions

Is Montclair Police radio encrypted?

Montclair Police is listed in our records with P25 AES-256 encryption — a listing we haven't yet verified against live talkgroup data. This agency is listed in our database as encrypting all of its radio communications, including routine dispatch. The listing is unverified — confirm current status on the live RadioReference database.

Can I listen to Montclair Police on a police scanner?

Likely not, if the listing is accurate: our database lists Montclair Police as fully encrypted using P25 AES-256, which no consumer scanner can decode. The listing is unverified — check the live RadioReference database for current status.

Why do agencies like Montclair 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 San Bernardino 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 San Bernardino County reverse the encryption decision?

Yes. Whoever made this call for Montclair Police can also unmake it; there's no technical lock-in. The approach that has worked elsewhere combines public-records requests, direct council pressure, and a coordinated local coalition.

What can I do about Montclair Police encryption?

Start local: show up when San Bernardino County officials discuss the budget for Montclair Police, and ask specifically why full encryption was chosen over a delayed feed or tactical-only approach. File a FOIA request for recordings or policy documents, and connect with others nearby who want the same information — a coordinated ask carries more weight than an individual one.
