A municipal police department polices their municipality plus any contract areas.

A county sheriff does or does not, in your case does, have police. They normally police unincorporated areas of the county and areas that contract with them for more intense patrol.

County sheriff's also often run court services, like they provide court security and bailiffs and the county jail.

Police departments are set up to offer services within an incorporated city. They are often controlled by a mayor, commissioner, or chief in conjunction with a city council.

A Sheriff is an elected official for a county. The policing part of the job is generally the same, but Sheriff's often run court security, prisoner transport, the jail, a civil division (deals with court paper services, evictions etc). In Oregon the Sheriff is also charged with Search and Rescue and patrolling of the waterways.

Sheriff of the County

Police of the City Limits within the said county.

I think Sheriff is usually for the whole county, police department is for a town or city.

And then you have the state police who operate statewide.

The Sheriff’s office has been established by the State Constitution. a police dept has been established under municipal regulations.

Police officers are city employees and sheriffs are county.
