What is the use of CCTV video balun?

What is a balun? A video balun is a wire connector device that allows UTP cable (such as CAT5) to transmit the video signal from CCTV cameras instead of using coaxial cable such as RG59.

How does a passive balun work?

Baluns work by transforming the original unbalanced (video/power/data/etc.) signal to a balanced frequency used by a different cable, like CAT5 UTP. Not only does this reduce interference, but it also allows you to transmit a signal much longer than the original application would allow.

Which cable is better for CCTV?

For CCTV frequency, RG59 and RG6 coaxial cables are recommended from Finolex Wires and Cables for optimum performance, non-distorted and noise-free video transmission.

What is a 1 to 1 BalUn?

BalUn means: Balanced to Unbalanced. This enables us to adapt an unbalanced fed system (coaxial cable) to a balanced antenna system (dipole antenna). The 1: 1 BalUn 800 Watt is suitable for QRO.

What is the purpose of a balun?

This transformer is known as a balun, and they are in operation in anything from telephone lines to transmitters. Baluns are used both to sort out the flow of AC signals and make the necessary impedance transformation between coaxial cable, which has a low impedance, and balanced loads, which have higher impedances.

Why do I need a balun?

A Balun is used to “balance” unbalanced systems – i.e. those where power flows from an unbalanced line to a balanced line (hence, balun derives from balance to unbalanced). As an example, consider a coaxial cable connected to a half-wave dipole antenna shown in Figure 1.

When should I use an antenna balun?

Baluns are used in many areas to transition between balanced & unbalanced scenarios: one key area is for radio frequency, RF applications for antennas. RF baluns are used with many antennas and their feeders to transform a balanced feed or line to an unbalanced one.

How far can you run Cat6 cable for CCTV?

Max length of Camera Cat5e/ Cat6 cable run Print Per Ethernet standards, the maximum length of a Cat5e and Cat6 cable run is 100 meters (or 328 feet).

Is CAT5 or coax better for CCTV?

Long distance: There are some definite advantages. To begin with, CAT5 gives long distance video transmission capability. By using a CAT5 cable you can run CCTV colour video footage over 1000 metres. If a coaxial cable is used, you will still be required to run an extra cable for data transmission.

How far can you run CCTV cable?

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.

Do baluns go bad?

That balun is usually the thing that goes bad. It’s pretty durable and works well, but most baluns are simply printed circuit boards and with enough hot and cold weather, they can crack. At the same time, some of the wiring that connects parts of the antenna together or connects to the balun can crack.
