Is it possible to use an external hard drive on my TRIDVR16? For example using a Western Digital, MyBook, 4 terabyte portable harddrive.
You can only use an internal hard drive to record video on a standalone DVR. The USB port is for video backup only for providing video evidence to law enforcement.
If you are looking to expand recording storage, certain DVRs and NVRs we carry have eSATA ports that allow connection to a external drive array we sell for up to 8 external hard drives.
