Klausimai apie šią prekę

How do I install the Reolink CX820 dome camera on a wall or ceiling and which step is most often missed?

Mount the base to the wall or ceiling, run a single Ethernet cable to a PoE switch or injector, then secure the dome; the step most often missed is verifying the PoE source delivers enough power before final tightening.

What maintenance will the Reolink CX820 need over time?

Clean the dome cover periodically to keep the F1.0 aperture clear, check the Micro SD card health if recording locally up to 256GB, and apply firmware updates when released.

What limit appears first during continuous 4K recording on the Reolink CX820?

The Micro SD card capacity tops out at 256GB, so sustained 3840×2160 capture will fill the card before any other hardware limit is reached.
