A balun can take many forms and may include devices that also transform impedances but need not do so. Transformer baluns can also be used to connect lines of differing impedance. Sometimes, in the case of transformer baluns, they use magnetic coupling but need not do so. Common-mode chokes are also used as baluns and work by eliminating, rather than ignoring, common mode signals. -Wikipedia | ||

− | The way a midspan works is that whenever a device is connected to it, a small amount of power is transferred along the cable; not enough to power the device, but enough to power the port. The midspan will then send a short signal over the network to ask the device if it needs power. A Power over Ethernet enabled device will return a message saying that it does require power which the midspan will then supply. A device which does not support Power over Ethernet will not reply and thus will not receive any additional power. This means that you can never damage a device that does not support Power over Ethernet by plugging it into a midspan. -[http://www.networkwebcams.com/ip-camera-learning-center/2008/09/30/glossary-term-power-over-ethernet-midspan/ | + | Transmission Distance with Midspan: 950 Feet |

A network switch (also called switching hub, bridging hub, officially MAC bridge[1]) is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device. Unlike less advanced network hubs, a network switch forwards data only to one or multiple devices that need to receive it, rather than broadcasting the same data out of each of its ports. -Wikipedia | A network switch (also called switching hub, bridging hub, officially MAC bridge[1]) is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device.

Cable Distance Limitations and Solutions
Description
When scoping out a potential location to install a security system, there are often challenges with cable distances. Longer cable runs can be especially challenging if you don't know how to work around these issues. Below are several solutions for HD-CVI and IP bases systems that need cable runs longer than the standard cable distance limitation.

- 1920H(1920×1080): 300m (984 Ft.) via Φ75-3, 400m (1312 Ft.) via Φ75-5
HDCVI 3.0

Baluns

Midspans
Transmission Distance with Midspan: 950 Feet
The way a midspan works is that whenever a device is connected to it, a small amount of power is transferred along the cable; not enough to power the device, but enough to power the port. The midspan will then send a short signal over the network to ask the device if it needs power. A Power over Ethernet enabled device will return a message saying that it does require power which the midspan will then supply. A device which does not support Power over Ethernet will not reply and thus will not receive any additional power. This means that you can never damage a device that does not support Power over Ethernet by plugging it into a midspan. -networkwebcams.com
