Is there a hard disk drive fitted to the DVR4-Alert?
The DVR4-Alert does not come with a Hard Disk Drive fitted, but it supports most IDE (also called PATA) hard drives up
to about 400GB in size. Check with your retailer for availability of suitable Hard Drives. Hard Drives can also be bought at
most computer retailers.
When selecting a Hard Drive You can calculate and estimate recording hours by using the following formula based on the
use of an 80GB Hard Drive.

I have fitted a new hard drive to my DVR4-Alert and it is working some times, but when I set it for mo-
tion activation the hard drive stops working, what is causing this?
Make sure your hard drive is jumpered to “Master”. This is done using the small plastic jumper blocks that are on the pins
that are usually between the data socket and power socket on the end of the hard drive. Most hard drives come with an
instruction sheet on the correct jumper setting for “Master”, and many also have the information printed on the label on top
of the drive casing.
Also make sure that you have connected both the IDE and Molex connectors to your hard drive correctly and that there
are no bent pins.
