Video Balun – Supporting Wide Range of Technologies

Technology has managed to bridge the entire world in a seamless manufacturing and transaction line. It relieves us from the burden of unnecessary and repetitive actions that are needed in our daily lives. A video balun may be well defined as a transformer linked between an unbalanced load or source and a balance load or source. There are two conductors on a balanced line, with equivalent current in the opposite directions while an unbalanced line has only one conductor and the current returns to it via common earth or ground path.

 

Some of the basic features of Video Baluns include:

 

  • They do not need power
  • They have built in noise filter and impedance coupled device.
  • Male connector of BNC directly mounted to video source of the camera.
  • BNC coax is used for screwing terminals therefore you need not waste your time on crimping the RJ-45 connectors.
  • They are compatible with the coax system for providing video and power over single twisted pair.
  • The cost of Cat5 cable as well as video balun is much less than the traditional wires, especially the expensive plenum coax cables.
  • Coax alternatives are much bigger than the UTP cables which mean that more cameras are routed through smaller diameter, making installation and termination much easier and faster.
  • Video signals can co-exist in same wire bundles as datacom, telephone and low-voltage circuits of power.

A security camera generally transmits videos over RG59 Coax Cable but in certain cases, it shall make more sense to use Cat5 cable. It is particularly beneficial if you have been planning to transmit video signals over longer distances. A solution to such a kind of problem may be the CCTV video balun which may be defined as impedance transformers. Impedance means total opposition which a circuit can offer to the alternating current flow or any other type of current running at a specific frequency. This is the combination of R (resistance) and X (reactance) measured in terms of ohms. In easy terms, a CCTV video balun can convert a video signal of 75 ohm for connecting 100 ohm impedance for the Cat5 cable and return it back to 75 ohm. If you want to make it work more efficiently, you can add 2 baluns, one for both the ends of a Cat5 cable.

 

Making use of a video balun may save a lot of time of the user also. For example, if you have been working in a huge office building and want to install security cameras over there, you can make use of any unused Cat5 telephone lines at your convenience. In this way, you will be able to remove the coax cables running from 1st to the 5th floor of the building. Another unmatched advantage of passing on video over a Cat5 cable is that the users have multiple pairs of wires because typically, there are four pairs of twenty two gauge wires so that the users can use a single cable for as much as 4 cameras. You can either power the cameras at camera itself or use separate Cat5 cables.

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
