Digital recording is the next step in surveillance. While analog recording is
still the most common method of recording, the benefits of going digital will
soon change that.
Instead of using tapes to store video, DVR systems use hard drives.
This means that operators do not have to constantly change tapes. Since
video is digital data, it an also be easily backed up, or able to be exported to CD
or DVD discs.
Another benefit of using a hard drive is random access. Just insert date and time, and
footage of any part of the video can be accessed within a split second. The operator
can skip ahead or go backwards at any time, and with great ease. Live video can be
paused and replayed while the DVR keeps recording live feeds in the background; an
impossibility with tapes.
The DVR system also allows for a number of different resolution
settings. With this, it is possible to capture video at a higher
resolution setting and improve picture quality, if required.
The DVR systems fit in with your existing equipment and cameras, so
intergrating your system does not become a costly project. It will allow usuage of
all your existing front end equipment, such as joy sticks and controllers, multi-
plexers, etc. Our equipment only requires a mouse to work PTZs, however, we
know that a lot of surveillance techs are very use to the existing joy sticks they
have been using over the years, thus, they can still be used on our DVRs.
Not ready to overhaul your existing system? DVRs are upgradeable and
expandable. Our equipment is scalable, so you can start with one unit and
upgrade as your budget allows.
We provide a total solution to meet all your security and surveillance needs, from
one system to cover a single channel, to an unlimited amount of cameras. We
also provide complete solutions for LAN and WAN requirements, and best of all,
at the most competitive prices in the industry, for both DVRs and RAID 5
disk arrays.
All this functionality comes with an "easy to use" interface. Our equipment was
designed with input from the actual users of this type of equipment, the
surveillance and security techs, thus, it was basically customized to meet
their requirements. You will find that it is one of the easiest systems to use and
get around on. Most techs that have had the opportunity to use our equipment
have commented on how easy our equipment was to use. Call for a demo and
see for yourself.
