Can a hospital security guard use a radar gun to give “hospital tickets” to staff?

Question by thejenerator: Can a hospital security guard use a radar gun to give “hospital tickets” to staff?
The hospital I work for has a security guard who bought his own radar gun and will pull over employees for speeding in the parking lot or for running stop signs. Is this legal? I’m in California. The tickets aren’t actual fines, just warnings from the hospital but if you get enough of them you can be suspended.
Please let me know where you get your information from.

Sounds like the “rules” of the hospital…we have “rules” where I work too
