Distributing Video Over Cat5 and Cat7: Things You Need to Know About Video Distribution Through Cat5 or Cat7

When thinking of setting up your home video system, it means that you should know something about distributing video over CAT5 and CAT7 because it is the kind of system that will broadcast optimum performance. It also means that you can now have your source from a distance away from the display device, television or monitor.

There are three (3) general types of video distribution system:
1) Analog or Baseband
2) Internet Protocol
3) Radio Frequency

Any of these types may use coaxial cables, category 5 or more commonly known as CAT5 cables, CAT5e, CAT6, CAT6e or CAT7 cables. What are the differences between them?

1) CAT-5 distributes video up to 100M.
2) CAT-5e 350M.
3) CAT-6 and CAT6e distributes video as far as 550M to 1000M
4) CAT-7 is rated from 700M to 1000M.

Viewing Video Over CAT5 or CAT7

Video over CAT5 or CAT7 like those delivered by CATV, data, and telephone are all distributed in similar wiring closets. It delivers videos that may run along a distance of 100M for CAT 5 or even up to 1000M for CAT7. Video over CAT5 or CAT7 all goes out on the same cabling system. The system is channeled in a passive broadband balun that converts any uneven coaxial signal into a balanced signal through the video over CAT5 or CAT7. Even when distributed to different channels simultaneously, it will not slow down the network because the air analog signals do not travel on that similar network, and thus, it does not rely on the bandwidth of the video signals.

Presently, the use of FTP or UTP cables for audio and video needs is prevalent. Instead of using coaxial cables, CAT5 and CAT7 cables are used. Coax are first installed into the hubs and everything else is distributed through the FTP/UTP. Video over CAT7 or CAT5 for that matter are now possible at a limited cost. There is ease in the installation and location change is not a big deal. All one needs to do is connect patch cords from the distribution hub to the patch panel and have a single port converter connected to the television.

Advantages of a Video System Using CAT5 and CAT7

1) Video over CAT5 or CAT7 is cost effective as it eliminates the need for additional coaxial cables.
2) Configuration of video over CAT5 or CAT7 is much easier than having multiple splitter taps, amplifiers and combiners of coax.
3) A high quality signal is maintained as the distribution system of video over CAT5 or video over CAT7 uses active RF video hubs. It makes automatic slope adjustments hence all video channels’ image quality is sustained.
4) The video distribution system of CAT5 or CAT7 can carry out voice and auxiliary signals simultaneously. There are no interferences between the voice and video data.
5) A system with video over CAT5 or CAT7 allows video streaming from the computer and it is made possible through a broadband video system.

Distributing video over CAT5 and CAT7 is made possible through an RF broadband system. It broadcasts CATV, HDTV, internally generated video, video-on-demand services, and satellite videos through twisted pairs of CAT5 or CAT7 cables.

Know the difference of how your video system will work. Systems working with video over CAT5 and systems running video over CAT7 will have their own advantages and disadvantages that you have to evaluate.

Are Free Sound FX Sites Doing Things Legally?

Recently, there have been a number of cases involving sound effects companies that are offering “free” sound effects as an enticement for people to sign up for their free accounts. Often times this is in order to harvest email addresses and names for marketing purposes or to sell lists to other marketing companies. The problem is that some of these sites are using copyrighted materials illegally. When companies do this they are not only neglecting their customer’s rights to privacy, but also placing them in potentially precarious legal dangers from the rightful copyright owners.


The issue has often risen from people who are either tired of buying sound effects legally, or who just don’t understand the legal implications and then post blogs on the web, solicit their friends and colleagues, and get people to search their computers for sound effects and then upload them to their newly developed, free sound effects site. Their intentions may be perfectly innocent, giving producers access to a wide variety of sound fx in one centralized location, but the real problem is that most of these uploaded sound effects are copyrighted and subject to the same copyright protections as music, movies and everything else.


There have been cases where people download sounds from these free sites to use in jobs for their paying clientele. Only later to get embarrassing and potentially career ending complaints, letters and law suits from their clients, who in turn have recently been contacted by the copyright owner’s attorney for copyright infringement. Not only can this devastating affair make you and your company look unprofessional, it is highly irresponsible as well. Nobody wants to be reflected poorly in professional circles, and in the highly sensitive environment of copyright law and the legal issues surrounding digital media, companies are coming down harder and people are treading lighter than ever before.


This is why it is important to make sure that the sound effects you are using have been obtained legally and with the appropriate licenses. There are many sites out there that offer sound effects legally. Some of these sites are free, others will charge a nominal fee, and still others may create sounds specifically for you that are licensed only to you. It is true that most of the time if you want a really high quality sound effect you will most likely have to pay for it, but the fee is usually small, ranging anywhere from a few cents to a few dollars, and more often that not it is completely worth it!


If you do want something custom built for you, you will probably pay more for it, but this sound will be licensed only to you and your production and will most likely never be available to the general public, unless releasing it was part of your sound effects/Foley creation agreement or if some one steals it and publishes it illegally.


Your best option is to play it safe. Most of the time the sounds you acquire from legitimate sources will be much higher quality anyway and will thus make your production sound much sweeter!
