It was probably an Arash drone. Check the specs.

2 of them hit Eilat target 45 minutes earlier, and just 10 minutes before this one happened, Israel had alerts all over the east Gallilee area, searching for a drone just like this one.

Then Iran launched their 50+ missiles to coincide with this drone and others like it. Then this video in OP happened.

Note the slow speed of the missile or drone. Suggesting it was a drone.

150kg warhead looks about right too based on the video.
