Check out this new, underwater “trail camera” by SpotX that is triggered by a Vemco acoustic tag:
Similar to a wildlife trail camera, the Spot X underwater camera trap can trigger a camera based on a range of input stimuli. The first use-case triggers a GoPro Hero 8 Black using the ping recorded by a VEMCO/InnovaSea VR2 receiver. However the system is flexible and can interpret PWM, RS-232 or any other analog sensor signal, and can be customised to work with many other cameras.
