Frequently Asked Questions
Is Sunnyvale Police radio encrypted?
Yes — Sunnyvale Police's radio system runs on P25 AES-256 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 Sunnyvale Police on a police scanner?
No. Sunnyvale Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Sunnyvale Police encrypt their radio?
Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Santa Clara County where an open channel caused harm. The costs need no such documentation: reporting on police department response slows down, and mutual-aid coordination gets more awkward, immediately.
Can Santa Clara 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 Sunnyvale Police encryption?
Contact the officials who oversee Sunnyvale Police's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Santa Clara County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
