Multi Channel Voice Logger |
|
 |
|
Basic module
is for 4 - channels. Number of channels can be increased upto 256
as per requirement. Interconnection of all modules in one cabinet
enables combined working of all modules i.e. combined recording,
search and play of all audio channels. Each 4 - channel module is
with dedicated hard disk. The attached computer will store the parallel
data in its own hard disk. When for any reason computer Hard Disk
does not take voice data, record can be called from dedicated hard
disks of 4 - channel modules. |
