A single cricket match can carry more cameras than most other sports. The count is driven by the geometry of the game rather than by production ambition.
The game reverses every over
Bowling alternates ends, so every angle needed at one wicket is needed in mirror image at the other. A camera behind the bowler's arm at one end is useless six balls later.
That doubling applies to the main high cameras, the low ones at ground level and the tight lenses on the batter. The core set is effectively built twice before anything else is added.
Directors also cut between ends in a fixed rhythm, so both sets must be manned and matched for colour and exposure. A visible difference between ends is obvious across a long innings.
The field is enormous and circular
Action occurs anywhere in a large oval, and a boundary catch on one side is as decisive as a delivery in the middle. Coverage has to reach the rope at every point.
Fixed cameras are therefore ringed around the ground, supplemented by operators who follow the ball. Wide areas that rarely see action still need coverage for the occasions when they do.
Overhead coverage comes from a suspended cable camera that can move across the field without obstructing play. It provides the descending shots used for field settings and celebrations.
Officiating systems need dedicated views
Ball-tracking requires several high-speed cameras placed at surveyed positions, and those cameras cannot be repurposed for pretty pictures. Their framing is fixed because the software depends on it.
Edge detection uses another set, typically ultra-high-speed lenses trained on the bat and pad, plus stump microphones feeding an audio trace synchronised with the images.
Run-out and stumping decisions rely on cameras aligned precisely with the crease lines. An angle a few degrees off produces parallax that makes a close call unreadable, so the position is surveyed.
Small cameras add the intimate angles
Miniature cameras sit inside the stumps, looking back down the pitch and sideways along the crease. They provide shots impossible from the boundary and are used constantly in replays.
Similar units are mounted in the sightscreens, on the boundary rope and occasionally on umpires. Each is cheap individually but each needs cabling, power and a slot in the vision mixer.
The helmet and player-worn units used in some competitions add another layer, along with the wireless links and frequency coordination those require inside a crowded stadium.
Replay depth drives storage as much as cameras
Every camera is recorded continuously, not only when it is on air. A decision review may call for an angle that was never broadcast, so all feeds must be retrievable instantly.
That means server capacity scaling with camera count, and operators whose only job is to find and cue the relevant angle within seconds of a request from the third umpire.
The truck's size therefore reflects the officiating requirement more than the viewing one. Much of the equipment exists so a decision can be checked, not so a shot can be shown.
