City of Fairfax Police Encrypt Dispatch: DC Suburb Scanners Dark

On July 13, 2026, the City of Fairfax (VA) Police Department encrypted its primary dispatch radio channel — a separate jurisdiction from the already-dark Fairfax County Police — closing one of the last remaining public-safety radio windows in the Washington, D.C. suburbs. The move came as part of a coordinated rollout with the Fairfax County Police Department, whose eight district dispatch channels went encrypted the same day, according to FFXnow. The good news for scanner listeners: fire and EMS dispatch in the region remains open — for now.

What Changed on July 13

The City of Fairfax Police Department, which serves the independent city surrounded by Fairfax County, switched its primary dispatch channel to encrypted operation effective July 13, 2026. The department announced the transition in an official city press release, confirming that scanner listeners can no longer hear police dispatch traffic in real time.

The City of Fairfax and Fairfax County operate on the same Fairfax County Public Safety Radio System, which also hosts the Town of Herndon Police Department and the Fairfax County Adult Detention Center — all of which may be affected by the system-wide encryption transition.

Why Encryption: Privacy, Safety, and Scanner Apps

The city’s press release cited victim privacy, officer safety, and concerns over “real-time monitoring and redistribution of sensitive police communications through scanner applications” as the rationale for the change. It’s the same justification Northern Virginia agencies have used as they push toward full encryption of the regional public-safety network.

That rationale — particularly the focus on scanner apps republishing live police traffic — is increasingly common across the country as departments respond to live-dispatch feeds and social-media redistribution of raw radio traffic.

What Scanners Can Still Hear in the DC Suburbs

Critically, Fairfax County Fire & Rescue confirmed it has “no plans in the future to encrypt our primary radio channels”, meaning fire and EMS dispatch remains the one actionable window for scanner listeners in the region. If you want to keep monitoring what stays open, a police scanner that can receive the regional system will still pull fire, EMS, and other clear talkgroups even with police dispatch locked out.

Neighboring Loudoun County has faced similar pressure. An audit there exposed a transparency gap as the county encrypted its channels — see our coverage of the Loudoun County encryption transparency gap audit for how agencies in the region are handling public access.

The Transparency Debate in Northern Virginia

Independent public-safety reporter Larry Calhoun of News From the Concrete told FFXnow that the encryption wave “absolutely hurts transparency.” Calhoun suggested a compromise that preserves both officer safety and public access:

If this is about officers’ safety, then just delay the dispatches if anything.

A delayed-dispatch model — holding radio traffic by a few minutes rather than locking it out entirely — has emerged as a middle ground in several U.S. jurisdictions, letting reporters and listeners follow major incidents without exposing real-time officer locations.

Frequently Asked Questions

When did City of Fairfax police encrypt their dispatch?

The City of Fairfax (VA) Police Department encrypted its primary dispatch radio channel effective July 13, 2026, in coordination with the Fairfax County Police Department.

Is the City of Fairfax the same as Fairfax County?

No. The City of Fairfax is an independent city surrounded by (but separate from) Fairfax County. The two agencies share the Fairfax County Public Safety Radio System but are distinct jurisdictions.

Why did the City of Fairfax encrypt its police radio?

The city's press release cited victim privacy, officer safety, and concern over real-time monitoring and redistribution of sensitive police communications through scanner applications.

Can I still hear police in the DC suburbs on a scanner?

Police dispatch for both the City of Fairfax and Fairfax County is now encrypted. However, Fairfax County Fire & Rescue has said it has no plans to encrypt its primary channels, so fire and EMS dispatch remains open.

What is a delayed-dispatch compromise?

A model proposed by reporter Larry Calhoun and others in which radio traffic is held back by a few minutes instead of encrypted entirely, protecting officer safety while preserving transparency for the public.

Bottom line: With the City of Fairfax Police joining Fairfax County in encrypting dispatch on July 13, 2026, live police scanning in the DC suburbs has largely gone dark. Fire and EMS channels remain open for now — the last actionable window for listeners in the region. If you want to keep hearing what your local first responders still transmit in the clear, having a scanner tuned to the regional system is your best bet before that window closes too.
