Micro SD card
brand
Kingston 4GB, Kingston 1GB, Kingston 16GB, Transcend 16GB,
SanDisk 1G, SanDisk 4G.
Usually we recommend the 4GB (or higher) or industry-level high
speed card in case the slow speed results in data loss.
Please use active device for the audio monitor input, otherwise there
is no audio in the client-end.
General power adapter work temperature ranges from 0℃ to 40℃.
It may result in unstable performance if it works in the extremely too
hot or too cold environments. In this case, you may need to use the
industrial-level power adapter.
