Visible crew/equipment: During the structure fire, Johnny and Roy rescue the security guard, and when Roy breaks the window with the chair, we can see a couple of crew members, equipment, and lighting on a tripod, outside down below.
Visible crew/equipment: When Squad 51 is heading to 1511 West Hill, responding to the attempted suicide, in the closeup of Roy and Johnny en route, we see the reflection of Squad 51 as they're driving past houses/stores on Johnny's side. Just about as Roy says, "It should be it over there," in the reflection we see two crew members riding on the squad - one on top of the squad, and the other one standing on the back.
Visible crew/equipment: At the structure fire, after the security guard is safely down the ladder, Johnny follows him as Roy watches from the window, and when the fire flashes through the doors, we can see the hand of a crew member pushing the lower boxes causing them to tumble.
Visible crew/equipment: After Roy breaks the window with the chair, the guys place the ladder against the window and Marco starts to climb up. In the next interior shot, just as Roy and Johnny lift the security guard, right outside the window we can see the corner of something else (platform-like), besides the top of the ladder.
Visible crew/equipment: When Squad 51 arrives at the second location, 1511 East Hill, trying to find the correct address for the attempted suicide, the outline of Johnny's lav mic transmitter is visible at the back of his shirt.
Visible crew/equipment: While Early is listening to the heartbeat of the boy with a heart problem, Dixie is standing beside him, and on the glass case behind them we can see movement in the reflection, even though it's only the three of them in that treatment room.
Visible crew/equipment: During the structure fire, when Roy, Johnny and the security guard are in the upstairs room and Roy closes the doors, just as they start to walk toward the window, the moving shadow of the cameraman and camera are visible on the wall. The shadow is not moving in sync with the guys so we know it's not theirs.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
