Frequently Asked Questions
Is Arvada Police Department radio encrypted?
Yes. Arvada Police Department uses P25 AES encryption. This agency encrypts all of its radio communications, including routine dispatch. The public, journalists, and even other first responders can't monitor its activity.
Can I listen to Arvada Police Department on a police scanner?
No. Arvada Police Department has fully encrypted their radio communications using P25 AES. No consumer scanner can decode encrypted transmissions.
Why did Arvada Police Department encrypt their radio?
The reasons offered are almost always the same two: officer safety and operational security. Whether either was tested against a real Adams/Jefferson 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 Adams/Jefferson 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 Adams/Jefferson County officials are policies those officials can revisit when constituents press for it.
What can I do about Arvada Police Department encryption?
Put the question to whoever signs off on Arvada Police Department's radio budget: why full encryption rather than a delayed feed or tactical-only channels? File for the recordings and the decision documents alongside it, and link up with neighbours and local reporters in Adams/Jefferson County so the ask arrives as a group rather than a one-off.
