Security cameras typically transmit video over RG59 Coax Cable but in some cases it makes additional perception to utilize Cat5 cable. that is especially true when wanting to transmit the video signal over long distances. The solution to this type of problem is the CCTV video balun.
A CCTV video balun is definitely an impedance transformer. Impedance in accordance with this internet definition, is the complete opposition that a circuit offers towards flow of alternating current or any other varying current at a specific frequency. It is largely a mixture of resistance R and reactance X, measured in ohms.
In layman's conditions a CCTV video balun converts a 75 ohm video signal over towards correct 100 ohm impedance for Cat5 cable and then back again 75 ohm's again. In order for this to perform you require a few of baluns. One for every end of the Cat5 cable.
Using baluns can be a real time saver too. For example: What if you are in the commercial business office setting up and must install a security camera You can see if there are unused Cat5 telephone lines. picture eliminating the require run coax cable from the 1st towards 6th floor.
Another advantage of transmitting video over Cat5 cable is that you just have multiple pair of wires. usually you have 4 pairs of 22 evaluate wire so you can use one cable for 4 cameras. As a aspect be aware you ought to both energy the security cameras at the camera by itself or use a separate Cat5 cable. If you don't take this precaution, interference can occur.
