Countywide Law Enforcement

All police departments in Ingham County have a number designator assigned to the department.  
Most departments use this number as the first digit in their unit number. 
Lansing has their own dispatch channels, East Lansing/MSU have their own dispatch channel, and all other units share an out-county dispatch talkgroup. 
Lansing has several proprietary encrypted tactical/ops channels, as well as the sheriff department, and East Lansing/MSU also have their own. 
The tac/ops channels are often setup to scan and also pick up traffic on the main dispatch channels. 
Groups, such as MSU parking enforcement and contracted security, have their own operations/tactical (and dispatch) talkgroups, but also have access to main dispatch and tactical channels. 
Michigan State University also uses MPSCS for IPF and transit, and they do have some common interoperability talkgroups with law enforcement.

- MSU Breslin Center and Special Events use analog UHF radios that could talk to the old Harris radios and had patches to that system. Most Breslin Center activity is on 469.75 MHz, most Special Events is on 462.6. These are the last holdouts on UHF analog, after MSU Parking Enforcement and Greencoat Security in 2024. All other county security, law enforcement, public safety, as well as most public works are now on the MPSCS since late 2021. MSU Special Events are capable of operation on the old MSU PD Event conventional repeater, which was used by MSU Greencoat Security until recently. They may soon move to this repeater, and plan to get onto the MPSCS eventually. 
- All MPSCS-capable Ingham law enforcement and related radios have access to 33COM, 33ICMAIN, 33INGFIRE, MPSCS event channels, 700-MHz simplex, and 33SPEV1-10. Police radios also have access to 33ICOPS, several other encrypted channels (LEIN, detectives, interoperability with fire and EMS, etc), and proprietary tac/ops channels.
- Each department has their own proprietary tac channel, and a few have several, as well as proprietary ops channels. Generally, 'tac' channels are in the clear and 'ops' channels are encrypted.
