Looking for information I have found the glossy spider beetle (Gibbium psylloides), which is more similar to the video shown.
Thank you for the interest shown.

Approximate size: 3-4mm

Found on the roof of an old pharmacy that suffers from structural deficiencies that allow the entry of rodents, specifically Mus musculus (house mouse)
.
Mediterranean area: Murcia.
