The DVR considers any changes in pixels, brightness, contrast and color as motion.
Sometimes, even a slightest movement of a shadow, or camera noise is enough to
trigger motion recording.
9. Do I need extra speakers to hear the audio during playback which has audio?
The DVR does not have a built-in speaker to playback audio. A connection from the
audio output to a device with audio output is necessary to hear audio.
10. How are the settings preserved on the DVR?
The settings on the DVR are preserved on its internal memory, which is powered by
a backup battery when the DVR is powered down. A typical battery life is seven days.
The DVR, provided that the unit was powered down properly by pressing the power
button, also keeps a copy of the settings on the hard drive. When the battery power
is drained and the settings are lost from its internal memory, the DVR recalls the
settings from the hard drive when it is powered on at a later time.
11. How can I reset the DVR to the factory default setting?
The factory default setting can only be reset at the vendor or from the manufacturer.
12. What is the estimated recording time per recording settings?
The estimated recording time per recording settings will actually vary based upon the
environment and the images that the DVR captures. Please contact the vendor or
the manufacturer for an estimated recording time per settings.

It is projected to have 16 channel loop out by the end of year 2004.
14. Can two or more DVRs be connected and controlled using a single control
device?
