For this use, dedicated compact cameras are probably not the best fit. A fixed webcam/IP-camera style system is a more practical and usually less expensive approach.

Why it fits better:

• It’s a permanent installation, so portability and typical camera features matter less.
• Webcams or network cameras are available in many resolutions and price points.
• They can often be triggered or queried by software, so one button press—or even an automated sensor—can capture all five views.
• Images can go straight to a computer or server, which is much easier than relying on SD cards or consumer camera wireless workflows.
• Replacing or upgrading one camera later is simpler because you’re not tied to one camera brand’s remote system.

If you want the process to be very reliable, consider a fully automated setup: pallet enters position, a sensor triggers capture, and software saves the files to local storage and then syncs to Dropbox or similar cloud storage.

In short: use a computer-connected webcam or IP camera system rather than five consumer still cameras with remote triggers.
