After extensive cross-referencing, the exact string cp-unr-4k2161-v2 does not match a mainstream retail model from major brands (like Sony, LG, Samsung, or even standard Chinese OEMs like Eufy or Reolink). It strongly correlates with a generic OEM security camera SoC (System on Chip) board, a Linux-based IP camera driver package, or a component-level firmware for a specific batch of 4K IP cameras sold under brand names like Annke, Hikvision OEM, Uniview, or a no-name CCTV module.
