Video Surveillance Systems
What is the difference
between the different wireless frequencies?
2.4 GHz: 4
Channel video 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. All 2.4 GHz wireless cameras come with a transmitter and a
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 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
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 Video Surveillance 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? - The only camera we offer that comes with audio
is the DC-111W-AA.
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 video
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.
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.
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 Band Width And Frequency.
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.
What is LUX?
- LUX is the measurement of low light needed for the camera to view and
What is the operating
temperature of the surveillance 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
The storage temperature & humidity is -30ºC to +70ºC or
-22ºF to +158ºF
