|Frequently Asked Questions
Frequently Asked QuestionsWhat 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. 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. 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. What does "wired camera" mean?
- A wired camera is a camera that does not have a built-in wireless transmitter, but can be plugged into a separately purchased transmitter which will transmit the pictures to a receiver. The receiver then displays the picture through a TV or monitor. The receiver can also be plugged into a standard VCR configuration. If you don't wish to use a wireless transmitter, the camera can be plugged directly into a TV or VCR.
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 4 sections allowing you to view 4
cameras at once. Do you have
a monitor that has built in Quad? - No, we do not have a monitor
with built in Quad. 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 and the CA-100. 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? - Federal law prohibits the use of audio with surveillance
cameras except for law enforcment agencies and the military. 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. How many cameras
can I hook up to one TV? - Should I use Color or Black & White?
Color does not work well in dark conditions. Infra-red will not work with color cameras. Black & white cameras work much better in low-light conditions and offer a far crisper picture. Black & white cameras can be used with infra-red illumination devices.
How much will
the Yagi Antennas increase reception range? - The Yagi Mini Antenna
will increase your reception by 100 ft. and the Yagi Antenna will increase
your reception by 200 ft.
What is Varifocal? What is an auto-iris? Do you need

or DVR if you want to record. Will a 900Mhz
camera and receiver interfere with my 900Mhz cordless phone? - No

How long will
the camera last with a 9-volt battery? - The 434Mhz and the 900Mhz
camera will last about ten hours. The 2.4Ghz will last about five hours.
