Information listed in the following compatibility chart is only based on our lab test results. The actual performance and compatibility might vary due to the third factors (such as the change of manufacturing method and raw material) from time to time. For other EZVIZ devices not listed on the table, you may refer to those manufactures and models that have passed our tests.

Please note that only partial devices have 256G micro SD card support function including C1C, C2C, C6CN, C3W, C3WN, C6T. Meanwhile the firmware needs to be updated to V5.2.7 or higher. Or else only 128G micro SD card or smaller can be supported.
