The dispatcher's voice was that of Shaaron Claridge, a real Los Angeles dispatcher. Jack Webb thought using a real dispatcher for the voice-overs would lend authenticity to the program.
In keeping with the reputation of Jack Webb's series being scrupulously accurate about police procedures, selected episodes of this series were used in police academies as instructional films.
The paramedics from Squadra emergenza (1972) sometimes crossed paths with the cops at Rampart Hospital.
Martin Milner's daughter, Amy, made a guest appearance playing the daughter of a shopkeeper shot during a robbery. Look for her as Debbie McMahon in Victim of the Crime (1975).
After Martin Milner died on September 6, 2015, LAPD dispatcher Shaaron Claridge, who provided the voice of the dispatcher on the show for all seven seasons, broadcast the "End of Watch Call" transmission over the LAPD radio, recognizing Milner's performance on the show. Claridge's transmission was nearly three minutes in length.
