Visible crew/equipment: When Art, The Screenwriter, goes on his first ride-along with Squad 51, just as Art rambles on about the fire truck on its mission of mercy going 80 miles an hour, two shadows of mic/camera equipment are visible on the left and right side of Squad 51's hood. What's amusing is that a moment prior to this, Art actually says that they could mount a camera right on the hood of the truck, when they make the film about paramedics.
Visible crew/equipment: When Engine 51 arrives at the toy factory fire and comes to a full stop, we see the hunched over cameraman holding a handheld camera, with another crew member standing right behind him, and just as Captain Stanley opens the door and emerges, we see the cameraman being helped up and both men turning and moving quickly to their left, as Captain Stanley jumps off the engine.
Visible crew/equipment: When Station 51 is dispatched to the structure fire at the Kiddytime Toy Factory, while en route there's a shot from the POV of the top of Squad 51, and the reflection of the cameraman and the camera can be seen on the lightbar's chrome surface.
Visible crew/equipment: When the dispatcher calls for Station 51 to respond to the "structure fire at the Kiddytime Toy Factory," while Captain Stanley is at the radio receiver base station, the reflection of the camera equipment is visible on the back of the squad's cab as it trucks left.
Visible crew/equipment: When John and Roy help the driver out of the overturned armored truck, the bulging outline of the mic transmitter is visible on the left side of the driver's shirt, and when Roy's arm is around the man's waist, Roy even puts his palm over the mic transmitter as he bends to pickup the man's gun.

Visible crew/equipment: After the sniper surrenders, Captain Stanley instructs Engines 12 and 51 to come to the rear of the building, and a few shots later the camera moves alongside Engine 12 as it's turning the corner. In this specific shot, up ahead we are able to see set lighting (including moleeno-style array lights), equipment, crew and actors (in the blue paramedic uniforms), some sitting on chairs in front of the parking attendant's booth (which was shot at by the sniper during the scene).

As an aside, in the previous and following shots that crew member and wind machine fan are in the same spot where Chet and Johnny supposedly are.
Visible crew/equipment: When the guys are at the scene of the vehicle accident, after Roy asks Captain Stanley and Captain of 69 to assist the man to the top of the hill, the reflection of the array lighting is visible on the side of Engine 51 as Mike works the engine's pump panel.
