Yes. Monterey Park Police uses P25 AES-256 encryption. Everything this agency transmits is encrypted, dispatch included. For anyone outside the department — residents, reporters, neighbouring responders — the channel is simply silent.
Can I listen to Monterey Park Police on a police scanner?
No. Monterey Park Police has fully encrypted their radio communications using P25 AES-256. No consumer scanner can decode encrypted transmissions.
Why did Monterey Park Police encrypt their radio?
The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.
Can Los Angeles 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 Los Angeles County officials are policies those officials can revisit when constituents press for it.
What can I do about Monterey Park Police encryption?
Put the question to whoever signs off on Monterey Park Police'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 Los Angeles County so the ask arrives as a group rather than a one-off.
