DVR Systems welcomes a new product to our
line, the Road Guard. This one camera
system is easy to install and use. It will help prevent
accidents by alerting you if your vehicle drifts to the
right or left, if your stopped and the vehicle in front of
you is moving or if you are approaching a stopped car in
excessive speed. Not only will it help prevent accidents,
but it will record them too. Excessive G-forces will
activate the recording. A sudden stop, turn or bump is
recorded 12 seconds before it happens and 6 seconds after it
happens. The software used to view the video is easy to use
and can help custom Road Guard to your preference. Let
Road Guard be your extra set of eyes when
you need it the most.
