f.
USB
ports – The DVR has 2 USB ports located on the back of the unit. One port is
intended for the optical mouse. The second USB port is can be used for backing up files to
a separate drive (e.g., flash drive, CD/DVD burner, etc.).
g. Hard Drive Installation – Unless ordered with and preconfigured at the factory, the DVR
requires a DVR hard drive to be installed. This unit will support a single hard drive up to
2TB. Secure the drive in the bottom of the case using the four included screws. Then
connect the drive to the SATA hard drive cable and power cable. Be sure the drive is
installed securely in the case. When applying power to the DVR the unit should
automatically (i) detect the drive, (ii) alert the user to confirm initialization and (iii) begin to
initialize it. Note that when the drive is initialized it will be formatted.
Formatting the drive
will erase any existing data on the drive
.
Important Note Regarding Hard Drives
– Not all hard drives are fully compatible with
DVRs. If you have an existing hard drive you wish to use with the DVR you may install it at
your own risk and determine if the DVR recognizes the drive and correctly records data to
it. If you are considering the purchase of a hard drive, contact Securitytronix for
