Frequently Asked Questions
Is City of Lewisvile radio encrypted?
Yes — City of Lewisvile's radio system runs on P25 AES-256 encryption. A defined subset of this agency's channels is encrypted. The rest of the system continues to operate in the clear.
Can I listen to City of Lewisvile on a police scanner?
Partially. City of Lewisvile encrypts specific talkgroups rather than the whole system, so some channels may still be accessible. Check RadioReference for specific talkgroup status.
Why did City of Lewisvile encrypt their radio?
Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Denton County-specific evidence that open communications ever caused a problem, while the loss of public oversight and the friction with still-unencrypted neighboring agencies are both immediate and real.
Can Denton County reverse the encryption decision?
Yes, and some departments already have. Because encryption here is a choice rather than a technical necessity, the path back runs through the same people who chose it: budget hearings, records requests, and residents who keep asking in public.
What can I do about City of Lewisvile encryption?
Ask for the paperwork first — the policy that authorised encryption for City of Lewisvile, and the recordings themselves — because a specific request is harder to wave away than a general complaint. Then take what you learn to a council meeting, and bring others from Denton County with you.
