VGA Extender: Extend Clear VGA Video Over a Long Distance

An electronic device used to transmit VGA video over Cat5 / Cat5e / Cat6 UTP cables to long distances is the VGA Extender. It operates without hampering the resolution of the relayed signals. This piece of hardware lowers the overall cost of your system by increasing its lifetime via better media player protection. The greatest advantage being that you can put your expensive content PCs in a secure, temperature-controlled backroom where they can easily be accessed and maintained by service people. These extension devices increase the signal strength from a VGA port and are extensively used in schools, restaurants and conference rooms.

By eliminating the excessively long cables used between the monitor and the computer, they act as a cost efficient mode of transmitting video signals. The VGA Video Extender is available as a Cat5 VGA Splitter Extender with 1/2 / 4 / 8 ports to extend VGA Video from one source to multiple locations. The options available are VGA Video / Audio which will transmit both VGA Video and Stereo Audio over standard Cat5 UTP cable or VGA Video / RS232 Extension for use in digital signage configurations. Easy to install and requiring no additional device drivers for operations, they work on simple plug and play functionality. Sharp and clear images with resolutions of up to 1900 x 1200 along with equalization and video signal gain adjustment is provided by these devices.

The Cat5 VGA Extender is composed of a local transmitter that connects to the video source and a remote receiver that is placed next to the monitor. The two VGA Extender units are connected via Cat5 / Cat5e / Cat6 UTP cable and are powered using the included 12V power supplies. Some models of this extension device are available with a unique dual screen receiver which allows transmission to two back-to-back screens at the same time thereby doubling the value of your system. Compatible with various operating systems, these extension devices can be connected to any video source with a VGA connection. They work well with PCs, DVD players, VHS, DVRs etc. Since the VGA Extender provides secure access, control, and management, it is used by military, financial and government agencies.

Powerline Networking Analysis And Example Of The Technology

Building a computer network in your large home with two storey building is more difficult compared with a place with only one floor building and is many times frustrating. Thick concrete building generally contributes signal attenuation and dead spots in wireless. Running network cable is a hard work. But Powerline Ethernet adapter helps you build the network easily.

Should you build an address computer network from the scratch which comprise of first floor where your Cable television / DSL internet connection starts and the second floor where you would like to Expand the network wirelessly, you should assess your requirements to meet your needs. On the first floor, how no end of computers you need, how you are connected them-- wired or wireless. On the second floor, this is important because you need to hook up the first floor to the second floor where a thick concrete building will be a barrier whether you run the network cable television or wireless easy access.

In the first floor where your router entrance (with 4x Ethernet vents) is located is connected two desktop computers which are close each other with the gateway router-- a wired connection for each of the computer is easier. You just need to run a network UTP cable television from each of the desktop computer to the router Ethernet slots.

Now the challenge is how to join a number of laptop computers with Wi-Fi enabled and other Ethernet based devices in the second floor to allow them hook up and access the Internet? You have two choices-- you run a network cable from the first floor to the second floor, or you provide wireless easy access from the first floor to the second floor customers. To run a network cable from the first floor to the second floor you need an extra work most likely by drilling the hole or run the clutter of the cables that will just look messy.

You can add a wireless access point in the first floor and allow purchaser computers in the second floor get in touch wirelessly. But with the thick concrete building in between the first and the second floor the wireless signal strength received by buyer computers in the second floor would be drastically weak. Your wireless performance in the second floor would be poor.

The easiest way for your cabin computer network with two floors like this is to install a Powerline Ethernet adapter in the first floor and another adapter in the second floor. With Powerline Ethernet adapter, you can design high-speed secure building wide network using the power outlets in a single circuit buster. The TPL-401E2K Trendnet Powerline Ethernet adapter is a new high speed adapter delivering the speeds of up to 500Mbps (theoretical) via the power outlets.

In this case, you can put in one TPL-401E2K in the first floor and connect to the Ethernet vent of your router entrance. And then you can put in other Powerline adapters in each of the obtainable power outlets in place as necessary to meet your need. Put up one adapter in the second floor where you would like to deploy the wireless obtain point.

What this TPL-401E2K Does

Trendnet TPL-401E2K powerline adapter is a high speed adapter via power outlets delivering the speeds of up to 500Mbps (in ideal conditions). The adapter is provided with one Gigabit Ethernet vent which is ideal in delivering high speed applications such as streaming High Classification (HD) media and smooth video gaming. You can deploy up to 16 adapters in a network. For security connection, the adapter supports advanced 128-bit AES data encryption.

One thing to just remember in setting up the Powerline Ethernet adapters in a building is that the adapters ought to be in a single signal buster system. If there are two signal buster systems in your building, to cover the whole building network you need to make a link in between the routine breakers. You need to put up one adapter in one routine breaker and another adapter in the other routine buster and link them as a bridge.

Now you can effectively build your farm computer network providing wired connection in the first floor and wireless connection in the second floor using the TPL-401E2K Powerline Ethernet adapter as a bridge between the floors via power outlets getting rid of the clutter of the wires.

UTP cat-5 passive balun for CCTV camera system...?

I've been researching CCTV systems - standalone DVRs and cctv cameras - and I've come across something I don't completely understand. I'm looking at using "passive baluns" to connect each camera to the dvr. Now the descriptions in every listing I read says something along the lines of "passive device - no external power required". Does that mean simply that the BALUN itself doesn't need a power supply, or does that mean that when using baluns the CAMERA doesn't need an external power source?

It'd be awesome if the latter case were true, as my company is looking at a 16 camera system, and we'll be running somewhere around 4000ft of cable. It'd be nice if we could just run a cat-5 cable from each camera instead of a video cable to the dvr AND a power cable to a reserved power supply box.

Any suggestions?

p.s. - example of the baluns I'm looking at: http://www.2mcctv.com/product_info-VITEKVTTR1M.html

Thanks!

The Passive Balun means you can transmit a video signal using cat5 cable.

The advantage is that you can transmit video over a longer cable run, usually up to 300m using passive balun. Normal coaxial cables have a limit of around 90m. The twisted cable pairs in cat5 is also good at rejecting electro interferrence.

'No power required' or 'Passive' means that you do not need a powered amplifier or any power source to extend the VIDEO SIGNAL ONLY.....up to 300m.

'Active Balun' is a powered balun which means it will amplify the video signal up to 1200m or so.

If you use the cat5 cable to run power to the cameras, the balun will not make any difference to the distance you can feed power. After 60m of cable, the voltage on most cables start to drop.

If you want a long cable run to power your camera, use a 14v power supply for 12v cameras or 28v psu for 24v cameras. In this case any voltage drop over the distance of the cable will be slightly compensated by the higher originating voltage.

Here's a few tips
------------------------

1) Use a balun that has a power connector with it so you only need one device o make video & power conection on camera side e.g see the balun with the dc connector here http://www.cop-security-online.co.uk/acatalog/Shop__front_Passive_system_36.html

2) A trick I did on an installation with long distance cameras is use a 24vAC power supply then I used a 24vAC to 12vDC convertor guaranteeing I could get 12v on the camera end up to 250m away

Hope this helps.
