| The
digital video recorder that will work best for your application
will depend on 4 factors: the number of cameras that you will
have, the frames per second that you need, whether you want
a card, stand-alone or embedded system, and if you want remote
viewing.
Number of cameras:
Be sure to purchase a DVR that supports the number of cameras
that you need now as well as what you may need in the future.
Frames Per Second (fps):
Calculate your fps per camera by taking the total fps of the
system and dividing it by the number of cameras that you have.
For example, a 4 camera system with 100 FPS would give you
about 25 fps per camera. However our PC Based DVR
automatically allocates the FPS to the camera/s on which the
motion is happening.
Card, Stand-alone or
Embedded:
Card systems are good if you have a spare computer with the
compatible parts and operating system and the expertise and
time to build it, you can save yourself some money using this
do-it-yourself approach. Pre-built PC-based (standalone)
systems allow the convenience of just plugging in the cameras
and knowing that all of the hardware and software is
compatible and pre-tested.
Remote viewing:
You can view your cameras remotely either by connecting
directly to the system using a modem, (A)DSL through the internet,
or through your company’s network.
