I’ve seen some amateur projects popping up for camera and visual sensors that either sell the gear or schematics to make your own sensors. However, I haven’t seen any programs so far that seem expansive or organized enough yet. And, they’re currently only monitoring the sky and not objects in the water. The systems I’ve seen are also expensive or daunting for an average person to set up. I think one is bound to catch on and hopefully help establish public data on the phenomenon.
The odd thing is that the DoD, alongside AARO’s report downplaying UAP, had announced plans for a portable sensor system for UAP. The Gremlin sensors are intended to be able to provide broad coverage of the US and potentially the world. Japan has already considered using these or similar to monitor their airspace. The problem again is that the data is controlled by the DoD or individual governments setting these up.
