Is it possible to trigger cameras to begin recording footage based on RFID tag-read events?
It is possible, yes.
Most readers have input-output ports allowing users to connect other devices, including cameras. You could have a camera start filming if a tag was interrogated—or, in the case of a still-image camera, you could have the device snap a picture. Simply RFID‘s Nox system, for instance, integrates RFID with surveillance cameras. I am unaware of any off-the-shelf system that integrates with still cameras, however.
It is possible to link tag reads to video segments, so you could go back and quickly review a portion of a surveillance video during which a tag was being interrogated. This could be useful in determining what happened to a tagged item.
