What's the difference between a wired camera and
a wireless camera?
A wired camera needs a cable that goes from the camera
to a TV or VCR. The video signal is passed from the camera,
through the cable, and to your TV or VCR, which in turn
allows you to see the picture. All wired cameras must use
RCA cable to connect the camera to the TV or VCR. We have
cable available in 25-, 50-, 100-, and 150-foot lengths.
A wireless camera does not need an RCA cable connected
from the camera to the TV or VCR. The video signal is transmitted
through the air to the TV or VCR directly, or to a receiver.
However, wireless cameras still require power. You can apply
power by either using batteries, or by plugging the camera
into a regular wall outlet.

Do I need to get cable with my camera?
All wired cameras require RCA cable to connect your camera
to a TV or VCR. Cameras with a description that says wired
for Plug and Play Connection have two leads coming out from
the camera. One of these leads is for power. A power supply
is provided to plug into a regular wall outlet. The other
lead is an RCA video connection to connect to your TV or
VCR. The video connection is a female connection and additional
RCA cable must be obtained to connect to your TV or VCR.
We have cable available in 25-, 50-, 100-, and 150-foot
lengths. If the description says it comes with cable, then
you only need separate cable if the size specified is not
enough.

What is the difference between the different wireless
frequencies?
2.4 GHz: 4 Channel transmitter. Approximately
2" x 2" x 1/2". No tuning required. We generally
recommend 2.4 GHz over 434 MHz or 900 MHz, as the overall
video quality is better. Range varies from 200' to 700'
depending on environmental conditions. Operates on 12 Volts.
These units are FCC approved.
900 MHz: Amateur band. 4 channels available
in the 900 band. The signal goes to a dedicated receiver
that is tuned from 902-930. Our standard transmitter is
set at 916.5 MHz, but we also carry 3 other frequencies.
Manual or automatic switching receiver. Range can vary from
200-700 feet or more depending on environmental conditions.
Antenna is approximately 3 1/2 inches. Operates on 9 Volts.
434 MHz: Lower frequency amateur band.
Operates on one channel which is picked up directly by a
television. You do not need a receiver. With a TV: set to
channel 59, cable mode but remove actual cable from the
input, and use a UHF antenna (high gain increases the range)
ears to receive the signal. With a hand held TV: can be
received on UHF band just below channel 14. Range can vary
from 300-400 up to 1,000 feet. THe range can vary depending
on frequency interference and other environmental factors.
Antenna is approximately 6 1/2 inches. Operates on 9 Volts.
Note: 900MHz and 2.4Ghz wireless cameras require a
receiver to pick up the video signal. The receiver in turn
is plugged into the TV or VCR with provided RCA cable. 900MHz
Receivers are sold separately. 2.4GHz receivers come with
all 2.4GHz cameras and transmitters.

What is Resolution?
Resolution refers to the cameras ability to reproduce images
- the higher the resolution, the better.
RETURN TO TOP
What is LUX?
LUX is the measurement of low light needed for the camera
to view and record properly. In other words, LUX refers
to the amount of light that is needed for the camera to
“see.” This becomes important if you need the
cameras to “see” in low light. The lower the
LUX, the better.

What is CCD?
It is analog technology. The CCD camera has a little bit
higher resolution than CMOS. The camera also functions better
in low light. A CCD camera drains a little bit more power
than the CMOS cameras. It uses 12v instead of 9v. CMOS camera
is smaller than a CCD camera and works longer with the 9v
battery.

What is a Quad?
A Quad splits your monitor into four sections, allowing
you to view four cameras at once.
RETURN TO TOP
Do you have a monitor that has built in Quad?
No, we do not have a monitor with built in Quad.
RETURN TO TOP
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.
RETURN TO TOP
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 have
cable available in 25-, 50-, 100-, and 150-foot lengths.
RETURN TO TOP
Do I need cable on my TV to get channel 59 to work?
No, you just need the cable setting for your TV or VCR
and then turn it to cable channel 59.

Do the display screens work on the cell phone or
the beeper?
No. Nothing but the camera works on the cell phone and
the beeper.

Do any cameras come with audio?
The only camera we offer that comes with audio is the DC-111W-AA.
RETURN TO TOP
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. If you are using
the motion detector video system, you will need to buy a
VCR from us.

How do I hook up the Plug and Play connection camera?
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.
RETURN TO TOP
How many cameras can I hook up to one TV?
-Only one 434MHz camera.
-Three 900MHz cameras.
-Four 2.4GHz cameras. You will need a Quad or a Switching
Monitor.

Do you need a VCR to record or will the cameras
record?
You must have a VCR or DVR if you want to record.

Will a 900Mhz camera and receiver
interfere with my 900Mhz cordless phone?
No. The 900Mhz cameras are set to a different bandwidth
and frequency.

What is the operating temperature of the cameras?
The operating temperatures of the B/W cameras are -23°C
to + 50°C or -10ºF to +122ºF
The operation temperatures of the color cameras are -23º
C to +40ºC or -10ºF to +104ºF
