What's the difference between a hardwired camera and a
wireless camera?
A hardwired wired camera has 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 allows you to see the picture. All wired cameras must
use RCA cable to connect the camera to the TV or VCR.
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.
What's the difference between 900Mhz, and 2.4Ghz cameras?
Mhz (Megahertz) and Ghz (Gigahertz) refer to the different frequencies that
our cameras use.
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. Our cameras are sold with receivers unless otherwise specified.
900Mhz wireless cameras transmit 1000 feet line of sight. 2.4Ghz wireless
cameras transmit 600-700 feet line of sight. Line of sight distance is under
optimal conditions with no interference and no obstructions between camera
and receiver.
So which one should I get?
If you have a 900MHz cordless phone, go with the 2.4GHz. If you have a
2.4GHz phone, go with the 900MHz. Phones near the same frequency as the
camera may interfere with the video signal.
If you don't think it will matter, then go with the 2.4GHz systems. They
have shown to be less prone to other signal interference than the 900MHz
systems. Other signal interference could be wires in the walls, the type of
walls you are transmitting through, or even appliances. It's recommended that
you use 2.4GHz systems if you are inside a structure and going through walls.
The signal stays stronger through walls.
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. If the description says it comes with cable, then you only
need additional cable if the size specified is not enough.
Are the cameras difficult to set up?
Both the wired and the wireless cameras are very easy to set up. You do not
need any special knowledge or skills to set up and operate these hidden
cameras. Basically, all you do is apply power, either by plugging it to a
regular wall outlet or by using batteries.
For a wired camera, you plug the RCA cable into the camera and run the
cable to your TV or VCR. Follow your TV or VCR instruction manual for viewing
the video input.
For a wireless camera with receiver (900Mhz or 2.4Ghz), apply power either
by plugging it to a regular wall outlet or by using batteries. The receiver
plugs into a wall outlet as well or you can use a battery pack. The receiver
plugs into your TV or VCR the same as wired cameras.
Can I use my camcorder to record?
You can use a camcorder or any video device that has a video-in port that
will accept RCA cable. Depending on your input port, it may be necessary for
you get an RCA to BNC connection adapter. These are easily obtainable at any
Radio Shack for $2-$4.
Do the cameras come equipped with audio?
Covert use of video and audio together is reserved for law enforcement
personnel only. We do not carry any hidden cameras that have audio
capability. Audio is only available to law enforcement agencies due to
federal US law**.
I have a 2.4GHz telephone system, will that be a problem?
There are
a number of possible problems. When the phone is picked up, the picture may
go out. You may not get any picture at all. There may be a horizontal hold
type problem with the picture. Problems may vary because of all the telephone
manufacturers and the different telephones. If you have a 2.4GHz phone system
or any other 2.4GHz system in your home or office, please consider
hard-wired, 900MHz., or replacing your existing 2.4 appliance.
What is Resolution and Lux?
Resolution refers to the cameras ability to reproduce images. The higher
the resolution, the better. 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.
Special Frequencies also Available.
