Texas Police Radio Encryption: DPS, Houston PD, Dallas PD & Statewide Status
Texas DPS encrypts statewide channels and Houston PD encrypts some of its traffic, but many local Texas departments—Fort Worth, San Antonio, El Paso, most rural counties—still run open communications. The contrast with neighboring states that have gone to blanket encryption is real and worth fighting to preserve.
Monitor Texas's open agencies—before encryption spreads
San Antonio, Fort Worth, El Paso, and much of Central and West Texas remain open. DPS and NTIRN suburbs are dark, but a lot of the state still runs unencrypted P25. Encryption is still the real fight—here's the stack listeners use to cover what's left, plus NOAA weather for tornado season.
Texas at a Glance
DPS encryption varies by region, and most local Texas agencies have held on to open communications. San Antonio, Fort Worth, and El Paso remain accessible. Houston and Dallas have partial encryption mostly on tactical channels. Texas has moved more slowly toward encryption than California, and local control has been the main reason.
The Brazos County case in December 2025—where a college-town department encrypted without public notice—showed that the Texas pattern can change quickly and quietly. Community pushback was strong but came too late.

Regional Analysis
Houston metro
HPD's main dispatch runs on open P25, but tactical operations, SWAT, and specialized units are encrypted. Harris County Sheriff follows the same pattern. The country's fourth-largest city still offers meaningful scanner access.
- HPD: Main dispatch open, tactical encrypted
- Harris County Sheriff: Partial encryption
- Suburban agencies: Mostly open
- Scanner access: Possible with P25 scanner
Dallas-Fort Worth
Dallas has moved toward partial encryption while Fort Worth stays open. The two cities share the same metro area and face the same crime landscape—making Fort Worth's continued transparency a direct counter-argument to Dallas's decisions.
- Dallas PD: Partial encryption, trending more
- Fort Worth PD: Open and accessible
- Tarrant County Sheriff: Open
- Suburban agencies: Generally open
San Antonio/Austin
San Antonio, Texas's second-largest city, runs fully open P25. Austin has tactical encryption but keeps main dispatch accessible. Central Texas is the best region in the state for scanner access.
- San Antonio PD: Fully open
- Austin PD: Mostly open
- Bexar County Sheriff: Open
- Travis County Sheriff: Partial
West Texas/border
El Paso runs open communications despite being one of the larger border cities in the country. Rural agencies across West Texas lack the budget for encryption upgrades and face no meaningful pressure to encrypt.
- El Paso PD: Open
- Border Patrol: Federal (encrypted)
- Rural sheriffs: Generally open
- Small departments: Mostly analog/open
NTIRN: North Texas Going Dark
A growing number of NTIRN agencies are encrypting
RadioReference listeners have documented a growing number of agencies encrypting on the North Texas Interoperable Radio Network (NTIRN), affecting communities across the Dallas-Fort Worth metroplex. Verify current agency-by-agency counts and talkgroup status directly at RadioReference rather than relying on any single snapshot — the picture changes as agencies join.
The NTIRN encryption wave has largely happened without the public debate that preceded encryption decisions in Denver or San Francisco. Residents in affected communities should attend local council meetings and demand transparency policies before more agencies join.

Encryption Without Notice (December 2025)
On December 8, 2025, Brazos County—home to Texas A&M University—encrypted law enforcement radio without public notice or community input. Fire department channels were explicitly excluded. The decision came in the shadow of the Uvalde shooting, where radio recordings had exposed the delayed law enforcement response. Rather than addressing accountability, Brazos County removed the public's ability to monitor future responses.
By the time most residents knew about the decision, it was done. Local government agendas need active monitoring—encryption proposals rarely get advertised as such.
Protecting scanner access in Texas
Much of Texas is still open. Keeping it that way requires paying attention now, before contracts are signed.
Watch city council agendas
Look for radio system upgrades, P25 transitions, or "communication security" line items. These are how encryption gets funded without a public debate.
File open records requests
Texas has strong public records law. Request information about encryption plans, vendor contracts, and the internal decision-making process before a vote happens.
Build a coalition
Connect with local journalists, neighborhood associations, and fire and EMS personnel who depend on scanner access. A broader coalition carries more weight at a council meeting.
Reference Uvalde
Radio recordings from the Uvalde response exposed failures that official statements did not disclose. That is the concrete Texas case for why scanner access to police radio matters.
Frequently Asked Questions
Are Texas police scanners encrypted?
Texas is split, and DPS encryption varies by region rather than being statewide. Many local departments remain open. Houston and Dallas have partial encryption on tactical channels, while San Antonio, Fort Worth, and El Paso maintain open dispatch channels. Texas has been slower to encrypt than California, but the trend is moving in that direction.
Can you listen to Houston police scanner?
You can still listen to Houston Police Department's main dispatch channels on P25 digital scanners. However, tactical channels and some specialized units are encrypted. Harris County Sheriff also maintains partial access. You'll need a digital scanner capable of P25 to listen.
Is it legal to have a police scanner in Texas?
Yes, owning and using a police scanner is legal in Texas for personal use. Texas has no statewide restrictions on scanner ownership. However, using a scanner to aid in committing a crime is illegal. Some jurisdictions may have local ordinances, but generally Texans have full rights to monitor public safety communications.
Why did Brazos County encrypt without notice?
On December 8, 2025, Brazos County (College Station/Bryan area) encrypted law enforcement radio without public notice or community input; fire department channels were explicitly excluded. This came in the shadow of the Uvalde shooting response criticism. The sudden secrecy raised concerns about accountability, especially given Texas's transparency traditions.
Which Texas cities still have open police scanners?
Several major Texas cities maintain open or mostly open police communications: San Antonio, Fort Worth, El Paso, and many smaller cities. The Central and West Texas regions are generally more open than the Dallas-Fort Worth and Houston metro areas where partial encryption is more common.
What you can do
Encryption is a policy choice, not a technical requirement. Here are the next steps that have worked in Texas and elsewhere.
