| How does motion detection work? Through the camera or software?
Motion detection works through the software in the DVR system
by recording video when pixels in the image change. Most Security
DVRs offer a sensitivity scale so the user can set the sensitivity
of the motion detection.
Can I view live and recorded video locally?
Yes.
Can I view live and recorded video remotely?
Yes, most of our Security DVR systems are Internet enabled.
You can view live and recorded video from anywhere through
the Internet. Some systems support off-site viewing via mobile phone.
What kind of broadband do I need? How much bandwidth?
Basic DSL or cable will suffice in most cases.
Can several users view one site at once?
Most Internet-enabled Security DVR systems allow multiple users
to view the same site simultaneously. However, as more people
look at the same cameras/DVR at the same time, the bandwidth
will be shared between them.
Can I record audio?
Yes, if the Security DVR system comes with an audio option
you can record audio. Most analog cameras do not come with
built in audio, so you will probably need a separate microphone.
Can I listen to live and recorded audio remotely?
Yes, some of our Security DVR systems have that option. With
an optional audio module, you can listen to live and recorded
audio from anywhere through the Internet.
How many cameras do I need?
This will depend on the size and layout of the area you wish
to survey. On average, we recommend one camera per 1000 Sq. Ft.
Can I use my existing cameras?
Yes, you can use your existing CCTV cameras. Simply plug them
into the back of the Security DVR which replaces the VCR.
What camera lens size is the best for my application?
Viewtech Security carries a large selection of security camera
lenses, but the lens you will need depends on where you plan to
use it.
What is an Auto-Iris Lens?
An auto iris lens provides consistent video signal in areas
where light levels vary.
What is Lux?
Illumination is measured in units called Lux. For more information,
please refer to our LUX Explanation Page
Can I zoom in with a camera?
Yes, but you need a special camera called a Pan-Tilt-Zoom or
PTZ camera. Browse our selection of PTZ cameras and find the
one that is right for you.
What type of Operating System (OS) does the Security DVR use?
Most PC-based Security DVR Systems use Windows XP Professional,
and Standalone Security DVRs are Linux based.
What kind of cable should I use?
Coaxial cable, which is an RG59 and a pair of 18 gauge wire
What happens if there is power outage?
Most Security DVRs will come back on as soon as power is restored.
However, we suggest an uninterruptable power supply (UPS)
which provides a short period of backup power and also serves
as a surge protection device.
Can I use my cash register with your POS interface?
Our GeoVision and AverMedia systems work with most PC-based
and electronic cash registers. Contact us with the make and
model of your register, and we can tell you if your system
is compatible.
Can the Security DVR report an alarm?
Yes, some Security DVRs have that option.
Indoor/Outdoor?
Will the camera be used indoors or outdoors? Typically all
outdoor cameras can also be used indoors, but not all indoor
cameras can be used outdoors. Most cameras that are built with
exterior metal casings are considered weatherproof. A camera
that is classified as “weatherproof” is one that
can withstand freezing temperatures, rain, and heat. The
typical operating temperature of a weatherproof camera is
-50° C to 80° C. Vandal-proof or tamper-proof cameras
are also usually considered weatherproof. If the camera will
be installed in an area where it is a potential target to be
damaged, a Vandal-proof (tamper resistant) camera will offer
extra security to help prevent secure the premises against
would-be trouble-makers.
