Hajime's Monitor, Arifureta Vol 7

“Oh, hi Shizuku-chan. We spotted some people being chased by imperial
soldiers,” Kaori explained.
She pointed to the cube-shaped crystal, which showed a pair of rabbitmen being chased through a ravine by a group of imperial soldiers. The cube crystal was another one of Hajime’s artifacts. He’d crafted it out of sightstone, ore enchanted with Farsight, and transferstone, ore enchanted with magic that let it display things seen by other objects linked to it.
Hajime had equipped Fernir with a number of external camera-type crystals, and then linked them to the crystal in the bridge. That way, he could see everything going on outside from here. He’d dubbed this artifact SCD, or Solid Crystal Display. Shizuku leaned closer to the crystal and nodded in understanding when she saw what was displayed. Two rabbitmen girls were running for dear life through a dry ravine.

They were still a good five kilometers away from the scene of the battle.
