Yes, but requiring all triggers before firing is usually a custom logic/electronics job rather than a standard camera accessory feature.

The simplest low-cost method is a wired remote that fires when a circuit closes: replace the single switch with multiple switches wired in series. In a series circuit, the camera only triggers when every switch is pressed, completing the circuit.

If you want something more flexible, a trigger controller such as Camera Axe can handle multiple inputs/outputs and can be combined with wireless trigger devices. That’s a more advanced solution but is better suited to custom triggering logic.

Standard radio remotes like PocketWizard are good for triggering one or more cameras remotely, but they are generally used so one trigger fires all linked devices. They are not the simplest way to require multiple separate triggers in sequence or all at once unless you add extra control logic.

So in practice:

• cheapest: modify a wired shutter release with switches in series
• more flexible: use a programmable trigger controller
• standard wireless remotes alone: best for one-to-many triggering, not “all inputs required” logic
