Encryption Details
Verified Talkgroup Data
Verification Status
We don't yet have per-talkgroup data for Naperville 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 Naperville 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 Naperville Police radio encrypted?
Our database lists Naperville Police as using P25 AES-256 encryption, though this listing is unverified. Our records list a subset of this department's talkgroups as encrypted rather than the whole system. Verify the current per-channel status at RadioReference.
Can I listen to Naperville Police on a police scanner?
Possibly. Our database lists Naperville Police as encrypting specific talkgroups rather than the whole system, which would leave some channels accessible. The listing is unverified — check RadioReference for specific talkgroup status.
Why do agencies like Naperville Police encrypt their radio?
Agencies cite officer safety and operational security. Those are assertions rather than findings — no local evidence is typically produced — while the effects are concrete and land straight away on anyone who relied on hearing Naperville Police to know what was happening nearby.
Can DuPage County reverse the encryption decision?
It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by DuPage County officials are policies those officials can revisit when constituents press for it.
What can I do about Naperville Police encryption?
File a FOIA request for Naperville Police's radio recordings and encryption-decision paperwork, then show up to speak at a council or commission meeting. Find other residents or journalists in DuPage 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.
