Questions
How do hidden cameras work? A small board camera
is built into an everyday item. The camera can be wired which means
it is connected to the DVR or VCR using a cable. The camera can
also be wireless, in this case the camera transmits a signal to
a receiver that is connected to the DVR or VCR.
What is the difference between a wired and
a wireless camera? - Wired cameras have a video cable that
runs from the camera to your recording or viewing device such as
a DVR, VCR or monitor. Wireless cameras have a built-in transmitter
that sends the video signal to a receiver. The receiver connects
to your recording or viewing device.

sends what it sees to the receiver which is able to
pick up the actual video and transfer it through the
RCA cable to your TV or VCR (or other recording
device)"

How far can a wireless hidden camera
transmit? - Standard wireless hidden cameras can
transmit up to 1000 feet and high-powered wireless hidden
cameras can transmit up to 2000 feet. (Except baby
monitor nanny cam and button
hidden camera in the wireless version is up to 300 feet.)
Can I get audio in my hidden camera? - No you cannot. According to United States federal laws, audio
should not be used in a surreptitious manner. One example of surreptitious
interception is audio in a hidden camera. This includes pinhole
board cameras and all covert or hidden cameras; i.e., a clock radio.
Audio in a hidden camera or board camera is only available to law
enforcement agencies. Title 18, Section 2512.
How many wireless cameras can you have in
one location? - You can have up to four wireless cameras
in one location. You can view all cameras at once using four receivers
or you can use one receiver and switch to each camera. You will
only be able to view one camera at a time if you only use one receiver.
If you want to install multiple wireless cameras in one location
it's best to order them at the same time so that we can put them
on different channels.
Will a cordless phone interfere with wireless
cameras? - Cordless phone that operate on the 2.4 GHz frequency
will cause interference with 2.4 GHz cameras. Interference should
be minimal and usually occurs if the phone is between the camera
and receiver.
What is a 2.4 GHz wireless frequency? - A
frequency is used to transmit a signal or data like video. 2.4GHz
is the specific wireless frequency that our tranmitters use to send
video signal to a receiver. All of our wireless cameras operate
on the 2.4 GHz frequency. Range varies from 200' to 700' depending
on environmental conditions. These units are FCC approved.
Are the transmitters FCC approved? - The transmitters used in all of our wireless systems are FCC and
Industry Canada Certified.
What is CCD? - CCD is used in professional
cameras because of it's high resolution quality and it's ability
to record in low-light situations. CCD is basically a small silicon
chip that receives light and turns it into voltage variations which
makes up an image. It's usually measured in inches with 1/3"
CCD being the standard. They are higher priced but are great for
cameras that may require vision in near darkness.
What is a Quad? - A Quad splits your
monitor into 4 sections allowing you to view 4 cameras at once.
Will a Quad allow
four cameras to record at the same time? - Yes you can record all
four cameras at the same time. You also can record using a switching monitor,
which will record the camera that is showing at that moment.
Do the receivers work through walls up to
two feet thick? - Yes as long as there isn't excessive
amount of metal in the wall.
Do the plug and play connections require extra
wire to run the signal back to the VCR or TV? - Yes, you
need to buy the length of cable you need we offer the CA-25,
CA-50, CA-100 and the CA-150.
What is the difference between a DVR and a
VCR? - A Digital Video Recorder (DVR) system records high
resolution digital images to a hard disk drive (HDD) and eliminates
the requirement of maintaining VHS tapes. Since the video images
are stored digitally, the image quality will not degrade overtime,
as would a VHS tape when recorded over multiple times. The time-saving
search capabilities of a DVR will enable the user to locate the
desired video clips via user defined parameters (camera, time, date,
etc.) versus the fast forward and rewind functions of a VCR. A DVR
can be accessed remotely from anywhere in the world using the Internet.
How many hours will a DVR record? - The amount of time a DVR will record for is based on the size
of the DVRs hard drive, the number of cameras recording and the
number of frames per second it is recording at. One camera recording
in Real Time uses 1 GB per day. So a 16 camera system will use 16
GB in one day.
Do I need a VCR from you or can I use my own
VCR? - You can use your own VCR for recording. However,
the VCR will have to be recording all the time. Most VCRs can only
record for about 10 hours but we have special VCRs that can record
up to 1280 hours.
What is a DVR card? - DVR Cards enable
the user to convert their computer into a Digital Video Recorder.
The DVR Card(s) is typically installed in an available PCI slot
of a computer. DVR cards are bundled with video surveillance software
which allows the user to record and display multiple cameras simultaneously
from the camera site or a remote location.
What is a Plug and Play connection camera? - It is an RCA Video plug and a power plug on the camera
for easy connection to VCR or TV. This is done by running the RCA
(Aux) line into the VIDEO IN of the VCR or TV. The TV or VCR must
be set on the correct channel to view the VIDEO IN picture.
How many cameras can I hook up to one TV? - You can hook up as many cameras as your TV has inputs. Most TVs
have 2 inputs but when using a quad you can hook up four cameras.
Do you need a VCR to record or will the cameras
record? - You must have a VCR or DVR if you want to record.
How long will the camera last with a 9-volt
battery? - The Cyber Eye and BD-127 will last 5 hours.
Between what temperatures is it safe for cameras
to operate in?
Safe for B/W cameras to operate between -23°C to + 50°C
or -10ºF to +122ºF
Safe for color cameras to operate between -23º C to
+40ºC or -10ºF to +104ºF
It is safe to store cameras between -30ºC to +70ºC or
-22ºF to +158ºF
What is the operating voltage of a camera? - Our cameras range from 9 volts (CMOS) to 12volts, and also 24
volt professional models.
What is a varifocal lens? - A varifocal
lens is one where the focal length of the lens can be varied. This
is a fancy way of saying it is a zoom lens. Most varifocal lenses
have, and in almost all circumstances should have, an auto iris
feature.
What is a fixed lens? - A fixed
focal length lens cannot zoom. The focus is fixed. A fixed
focal length lens usually allows more light to pass through
the lens at a given focal length than a varifocal, or zoom
lens. This can be important in low light situations.
