This camera system is a nice companion to our wireless callboxes when
you need to both see and talk to visitors, but you can't run wire. While
this unit doesn't have the range of our callboxes, in ideal conditions
is can transmit a video signal up to 450 feet. How far the camera will transmit depends on a number of factors like
type of solid objects the signal will pass through such as walls and
doors, plus any other interference encountered. Your
range will likely be lower. The 7" Wireless Video Monitor Digital
Camera System has a seven inch monitor that enables you to
simultaneously monitor up to four digital wireless cameras. You can set
the monitor to view all four cameras in quad screen mode, automatically rotate
between all or some of the channels, or you can lock the screen on one
channel. The monitor also has RCA and BNC jacks for connecting to a TV,
VCR, DVR, or large screen observation system.
This portable digital wireless monitoring system uses encrypted
technology to deliver secure, quality video. This wireless camera and monitor like others of
its kind uses the 2.4GHz frequency range for transmission and receiving.
There can be a few problems for systems that use this range. One is that
this is the same frequency range that wireless computer networks use so
there can be interference. And second, if the devices are analog, other
devices in that range may be able to intercept the signal. So people
nearby may be able to see what's happening by your camera
The 7" Wireless Video Monitor Digital Camera System solves these problems not
only by using a digital signal, but by using FHSS technology (Frequency
Hopping Spread Spectrum). Essentially that means your camera's signal is
chopped up into tiny segments, or packets, and distributed over a wide
band of frequencies in the 2.4GHz range. Since transmission occurs only
on a minuscule section of these frequencies at any given time, the
signal being transmitted does not suffer from greatly reduced signal
degradation and also avoids blocked paths and other devices with
competing signals. Also, the strength of the signal being transmitted is
much higher then the a comparative analog transmission signal allowed by
wireless authorities around the globe.
Using FHSS requires the camera and monitor to be "paired." This
means that even if your neighbors have the identical monitor, they
cannot see what's happening on your camera. When you purchase the
system, the devices are already paired, but if you add cameras, you will
have to go through the pairing procedure before they will work with your
monitor.
The cameras have built-in IR LEDs,
which provides the camera with the ability to view images up to 46 feet
away in no/low
light conditions. The cameras also have a built in microphone so you can
listen in to what's happening around the camera area.
This kit comes with the monitor, two cameras, and all the mounting
accessories.
