Default Mic frequencies used by DPS

Any idea what frequency the DPS uses for their in car camera system where it transmits what the trooper is saying thru his lapel mic when making traffic stops?
Any other frequencies for other agencies such as PD's, SO's etc?

I believe most police camera audio systems use 2.4GHz digital spread spectrum which can not be received with a scanner.

If they are still using older equipment the might be on: Cordless Microphones - The RadioReference Wiki

Years ago I heard a few PDs in the DFW area on some of the 8 channels in the 169-171 MHz range.

Most of the older MobileVision units that the state provided for every city about 11 years ago included a VHF analog microphone. The unit inside the vault was just a VHF receiver.

There was an option that was available later to make them 900 MHz spread spectrum. That is where most of them are now. I would imagine DPS upgraded to that.

I remember years ago that I could hear some of the local SO and PD units with their Mobile Vision equipment. I just recently got back into scaning again with a BCD996XT and was wondering if it would pick up anything or not.
Thanks for your replys
