Power
The DVR’s power supply plugs into the socket marked DC 12V next to power switch (Item
number 2 in Picture 2-2). It is absolutely essential that you only use the power supply that
came with the DVR to ensure proper operation and to avoid damage.
We also recommend that you use an uninterrupted power supply (UPS) so that the system will
continue to operate in the event of a power loss. In addition, you should connect the DVR into
a UL-1449 rated surge protector. It should have a joule rating of at least 400, a response time
of 10 nanoseconds or less and a clamping voltage of no more than 330 volts.
Mouse
The included USB mouse will only operate if connected to the DVR through the USB port
on the rear of the DVR (Item number 5 in Picture 2-2). The USB port on the front of the
DVR’s screen is only for external USB storage devices.
