According to my research and the manufacturer's specifications, this should be possible. The cameras must be in the same WLAN and recording must be started separately for each camera; there is no centralised, manual recording function. There is also no limit in this sense, so recording can take several hours, depending on the storage space. With regard to the detailed app functions, I also recommend contacting the manufacturer directly, as functions may change depending on the update or firmware.

how? thank you
