Replacing built-in SD card
Some of the Reolink IP cameras (model 411WS/410WS/410S/411S) have a 16GB build-in SD card. If you want to expand the SD card to one with larger capacity, there is a possible way and the SD card capacity could be up to 64GB. However, it is our duty to remind you replacing the SD card can cause some unexpected issues. So we DO NOT recommend you to replace the SD card.
Replacing the build-in SD card requires you to disassemble the IP camera. Any improper operation may cause the destruction of wiring, electronic chip or the interior structure. If you really need a SD card with larger capacity, please ask someone with experiences for help and look out the wiring during the disassembling.
