Super Turbo RG59+2C Siamese Coax Cable with Power 0.75MM2 CCA Round
Wire
Siamese Cables:
Siamese Cables are usually those that have certain power wires
attached to them. While they are considered to be quite complicated
to handle, it does, however, provide transmission of both data and
power at the same time to security cameras. A combination of two
cables, it is made up of RG59 Coax and 2cores of 18AWG Power cable,
the former for video transmission quality and the latter for power
purposes. In other words, since RG59 is a coaxial cable, it helps
in running the video to the security camera, whereas 18AWG/ 2C
cable helps in the 24V AC/ 12V DC power to the camera.
RG-6
This particular cable is made for higher bandwidth, made of copper
and aluminum, and for higher frequency. Therefore, it isn’t ideal
for indoor CCTVs. It’s a lot heavier than its other types, thus
perfect for CCTVs used by city authorities, administrations, police
authorities.
RG-59
Similar to RG-6, the RG-59 refers to ‘Radio Guide’ while 59 refers
to the diameter size, i.e., .059 and uses a copper plate. This type
of cable is recommended for a lower bandwidth, therefore, it’s
ideal for CCTV installations particularly suitable for flats,
apartments, societies, hotels and other interior, relatively
smaller places. Hangzhou Aite RG59 coaxial cable is a foaming-based
dielectric system. With a super gas injected from the foam
insulation, the cable thus helps in providing a better quality
signal which eventually helps for better surveillance.
What is the Max Distance for CCTV Cable?
What is the max distance that installers can run CCTV cable for
video and power?
Here is a question that I received from a customer recently.
Hi thomas, can you please assist. Is it possible to run power cable
together with the video on RG59 Cable for a distance of 250 meters.
I am a new CCTV technician who has just faced a challenge on an old
installation which is not working properly.
Here is the information that I provided.
Analog CCTV camera video transmission is limited to 213 meters or
700 feet using RG59 coaxial cable, unless you use a video amplifier
like this one
Using this amp, you can run CCTV video up to 1000 meters / 3000
feet with RG59.
The max distance that you can run power cable to the camera without
voltage drop depends on the voltage, amount of power the camera
draws in amps, and the gauge of the cable that you are using. You
can use this voltage drop calculator and voltage drop chart.
