Recorder AKA (DVR)
Digital Video Recorder (DVR)
A DVR is a computer based digital recording
system that records video on to a computer hard drive. Using a hard drive
allows the recording system to record video for longer periods of time.
Motion Detection Triggers Recording
One feature of a DVR is motion detection.
How the motion detection feature works is: when the DVR detects motion in
one of the cameras, the motion in the camera triggers the DVR to start
recording and end recording after a set period of time. So the DVR is only
recording when motion is detected saving hard drive space and lengthening
recording history. When the DVR hard drive is full the DVR will than start
to record of the oldest recordings. The motion detection also has an alarm
feature that notifies camera system users of motion in the camera by
setting off a loud alarm when motion is detected with in the camera.
Remote Viewing via an Internet Connection
Another feature of a DVR is Network
Compatibility. Network compatibility allows the Camera system to be
connected to your computer network allowing the cameras to be viewed over
an existing network via a Personal Computer. Your internet connection can
also be configured to allow the Camera System to be viewed over the
internet. A computer and camera system connected to a high speed internet
connection would work best.
Another feature of a DVR is its ability to
either view all of the cameras at one time, allow the cameras to be viewed
one at a time manually, or to view all cameras via a time laps dwell
setting, the view on the monitor will automatically change from camera to
camera at a set time.

camera detection, and the cameras can be set to record at different times
of the day via a camera timer.
